It has no effect on the car, because it is used for air conditioning and refrigeration, and if it is in summer, it can make the car cooler.
Refrigerant is used in refrigeration and air conditioning systems to transfer heat energy and produce freezing effects. Refrigerant is an intermediate substance in the refrigeration process, which first accepts the cold amount of the refrigerant and cools down, and then cools other cooled substances, we call the intermediate substance refrigerant. It can also be called refrigerant.
Refrigerants include gas refrigerant, liquid and solid refrigerant, gas refrigerant mainly air, etc.; Liquid refrigerants include water, salt water, etc.; Ice and dry ice are used as solid refrigerants. The refrigerants commonly used in air-conditioning engineering are water and air. In daily life, the refrigerators and freezers we use, and the cold storage in the commercial industry, rely on air as the refrigerant to transfer the cold energy in the refrigeration process to the food in the circulating refrigeration process, so that the food is frozen and preserved in the freezer room (or in the cold storage refrigerator).
In the air-conditioning system, through the operation of the refrigeration unit, the refrigerant that enters the evaporator evaporates and absorbs heat, when the cold water in the evaporator is introduced, the heat is quickly exchanged in the evaporator, the heat is absorbed by the refrigerant and the temperature drops to become chilled water, and then the chilled water is exchanged with the treated air through the surface cooler in the air-conditioning equipment, so that the air temperature is reduced. In this refrigeration cycle and heat exchange process, the long-distance transmission of its cooling capacity to meet the air cooling requirements in the air conditioning system must have water and air as refrigerants. When less than 0 water is required as a refrigerant, substances such as salt water can be used.
As can be seen from the above, the refrigerant is used in the air conditioning system, so it has no negative effect on the car.

Air filter dirty: The air filter is designed to protect the engine and reduce wear, generally replaced in about 10,000 kilometers, if the replacement is not timely, there will be insufficient air intake to cause low idle speed, and the engine shakes, as long as the filter element is replaced. High Voltage Line Break:
High-voltage wire disconnection refers to the disconnection of the high-voltage wire core, which can affect the ignition and cause the engine to shake. Spark plug life: The spark plug has a lifespan, and the ignition efficiency is significantly reduced after more than 3-40,000 kilometers, and can affect the ignition, which is the most common failure, and the spark plug can be replaced completely.
Low idle speed: The engine idle speed value has been set in the computer, and when the number of revolutions is low to a certain range, the car computer will automatically adjust it. If the idle speed is too low and the jitter is beyond the control range of the computer, some cars have adjusting screws on the throttle to adjust the idle speed, and some cars can not adjust, this kind of car can check the idle valve, throttle, air flow meter, vacuum sensor, adjust the ignition time (car with distributor), you can increase the idle speed.
Low idle speed can occur even when the water temperature is low, so you can check and replace the thermostat. Abnormal water temperature: There is a normal range of engine operating temperature, and high water temperature will cause early ignition time, change in oil-gas mixing ratio, thinner oil viscosity, and poor lubrication performance.
The general fault cause is the jitter caused by the lack of antifreeze, the thermostat cannot be opened, the fan does not rotate, and the temperature of the temperature control switch is inaccurate. Fuel injector is blocked: The fuel injector of the EFI truck is a key component of automobile fuel injection, and the service life is very long, which can reach hundreds of thousands of kilometers.
However, because there is gum in the gasoline, the fuel injection hole of the fuel injector will be blocked, so the amount of fuel injected by each fuel injector is inconsistent, resulting in the inconsistent work of each cylinder and causing the engine to shake. The solution is to remove it and clean it. Carbon deposits, grease blockages:
The throttle, idle valve, and air intake hole will be blocked by carbon deposits, oil scale, and poor air intake after a period of use, which will affect the stable idle speed and shaking. It is necessary to inspect and clean the above parts with cleaning agent, and there is no need to remove them for cleaning. Cylinder pressure is low:
The engine has 3 cylinders, 4 cylinders, 5 cylinders, 6 cylinders, and 8 cylinders, and if one cylinder does not work well, there will be a lack of cylinder and the engine shakes. Three-cylinder engines are the most obvious, followed by four-cylinders. Check the cylinder pressure with the cylinder pressure gauge, and solve the fault of low pressure with Xinba.
Xinba has a unique effect on low cylinder pressure and unbalance. It can be added to the engine oil or directly added to the cylinder to restore the balance cylinder pressure. Precautions Engine idle value:
-
Many people don't like to buy a three-cylinder engine model, thinking that the three-cylinder engine shakes a lot and makes a lot of noise. So is it true that a three-cylinder engine can't be bought?
-
The engine power of the three-cylinder will be weaker, but there should be no shaking under normal driving.
-
There will definitely be an impact, and the jitter will cause the link parts of the car to loosen.
-
The vehicle shakes, drives weakly, and idles unsteadily.
The car fault light is on.

4. When reversing, you must pay more attention to the situation in the rear, you can get out of the car first to observe, and reversing matters.

As long as there is no high temperature, it doesn't matter.

The three-cylinder engine is a product of helpless design. The four-cylinder engine can easily solve the first-order inertia force and the second-order inertial force through the balance shaft. However, the three-cylinder engine cannot solve this dynamic balancing problem with the balance shaft.
Therefore, from the perspective of physical innate nature, the stability of the three-cylinder engine is far inferior to that of the four-cylinder under the same technical strength. In a four-stroke engine, the minimum number of cylinders that can maintain uninterrupted power output between cylinders is four-cylinder.
However, because the current car needs to develop to a small displacement, in the case of a small engine displacement, the volume of each cylinder is smaller, which will lead to a very bad low-torque data, in order to maintain the single-cylinder volume, only a three-cylinder engine can be developed.
-
Advantages of three-cylinder engine: the use of three-cylinder engine is a model below the displacement, its advantages are low fuel consumption, simple engine structure, low cost, low maintenance costs, even if the engine overhaul is at most more than 500 yuan, so the cost of use is low. Buying a three-cylinder car mainly depends on the owner's use of the car and the funds to buy the car.
If a large number of times are used in the city, only I prepare.
If you buy a car of 30,000 yuan or 40,000 yuan, you should choose a three-cylinder car with a displacement of less, which has a low cost of purchase and use, and is economical and fuel-efficient. Disadvantages of three-cylinder engines: The disadvantages of three-cylinder engines are:
Due to the small number of cylinders and small air intake, the starting and acceleration speed is not as good as that of the four-cylinder engine, and the power is enough to drive in the city, while the power is not too enough for long-distance running. Overall, the three-cylinder engine sedan is more suitable for urban travel, in the city it has enough power, due to the small displacement, light weight, good fuel economy performance, and relatively low maintenance costs. However, its absolute power is relatively small, and the power is slightly insufficient at high speeds, and the vibration and shaking are somewhat large.
And because of the high cost performance of these models, many shortcomings could be ignored under the conditions of the time. However, with the advancement of technology, the technology of the three-cylinder engine is also constantly improving, and the three-cylinder engine has become one of the research and development directions of many manufacturers, and the three-cylinder engine is no longer a symbol of backward technology.

Let's talk about the benefits first, compared with the four-cylinder engine, the combustion space of the three-cylinder engine is more concentrated, so the combustion efficiency is greatly improved, the fuel economy is greatly improved, and the emissions are also greatly reduced. The most stringent China VI emission standards in history are coming soon, and many old four-cylinder engines on the market actually do not meet the China VI emission standards, which is why there are more and more three-cylinder engines. In addition, when the three-cylinder engine is running, there is a 60-degree ignition interval between the cylinders and the cylinders, and there is no exhaust interference, so the turbo lag of the three-cylinder engine with a turbocharger is also small, which is also its advantage over the four-cylinder engine.
As for the disadvantages, it is actually more difficult to say, advanced technical components such as balance shafts and dual-mass flywheels make the NVH performance of three-cylinder engines even better than many four-cylinder engines in the same class. If you have to talk about the disadvantages, it may be contrary to the traditional concept of "the more cylinders, the more magnificent".
-
Is a three-cylinder engine good or not? The innate advantage of the three-cylinder engine makes the four-cylinder engine irreplaceable.
-
The advantage of the three-cylinder engine is that the production cost is relatively low, and the disadvantage is that the three-cylinder engine is obviously resonant compared with the four-cylinder engine model because of the structural limitations.
-
The only advantage is that it saves some fuel and the size of the engine is relatively small.
There are many disadvantages. The first is due to the unbalanced activity of the piston. The vibration of the engine is noticeably larger. The second is that the loss is different. Over time, an imbalance in the engine can lead to uneven wear and tear on components.
-
Replace the middle cylinder and change the piston assembly, which has no effect on the car, but must be re-run-in. The precautions are the same as those for new car running-in. After the break-in, change the engine oil and it can be used normally.
From top to bottom, the engine is the valve chamber cover, cylinder head, cylinder block (middle cylinder), and oil pan. The middle cylinder is the larger cast iron thing on the engine. The cylinder is equipped with crankshafts, connecting rods, bearings, pistons, piston rings, piston pins, and other accessories.

Does car fuel booster really work? So let's first understand what is Fuel Treasure, Fuel Treasure is a common name for the third generation of gasoline detergent (also known as, gasoline detergent or fuel additive), in order to solve the carbon deposition problem of the fuel system of EFI models, quickly restore the best working conditions of the engine, and can make up for the defects of gasoline in some properties and give gasoline some new excellent characteristics: such as improving atomization, reducing wear, protecting the engine, reducing emissions, etc.
Fuel treasure is a high threshold of technical products, the cost and a single bottle ** is higher, so it is a lot of low-quality products, and even counterfeit products are the hardest hit area, the use of counterfeit products not only can not play a role in removing carbon deposits, maintenance of the engine, but also is likely to cause damage to the engine, so be sure to buy from formal channels, such as physical stores, networks, regular 4S stores and other channels.
-
Fuel treasure is only for the oil channel to clean, the power impact is not large, and the damage can not be raised, but it is not recommended to add fuel treasure for new cars.
Fuel Treasure is a common name for fuel additives (also known as, gasoline additives or fuel additives), which is to make up for the defects of gasoline in some properties and give gasoline some new excellent characteristics, with the effects of cleaning system carbon deposits, increasing octane number, improving atomization, reducing wear, and protecting the engine.
The first thing to say is that carbon deposition is an unavoidable phenomenon in the process of engine operation, especially advanced direct injection engines and supercharged engines, the structure of the fuel direct injection system will exacerbate the generation of carbon deposition, resulting in problems such as decreased engine power and increased fuel consumption, so the regular use of maintenance-free additives is essential for the engine. In addition to the carbon deposits that are normally generated, the carbon deposits on the back of the intake valves are indeed more problematic for direct injection engines, and since they are unavoidable, they can only be removed by targeted cleaning. Normally, we can use the method of no-dismantling cleaning of the intake tract and intake valve to clean the intake tract and intake valves, compared with ordinary EFI (manifold injection) engines, the cleaning cycle of carbon deposits may be shortened depending on the specific use situation.
-
Is the car "fuel treasure" really useful, or is it a big hole?
-
Hello, I added it to the tank, and I can feel it improve after adding it. And because it does not contain metal components, it will not cause hard friction with the engine, which is harmless to the engine and can also remove carbon deposits.
-
Before launching a new car, automobile manufacturers have taken into account the domestic automobile use environment, including the quality of air and oil, so there is no need to use additives for automobiles, especially new cars. Additives are like tonics, if you take them when you are not sick, you will definitely make up for your illness.
-
Fuel treasure is only for the oil channel to clean, the power has little impact.
-
The damage is also not mentioned, but it is not recommended to add fuel treasure to new cars.
-
Four-stroke engines must have at least 4 cylinders to ensure uninterrupted power stroke. In addition, the four-cylinder engine can completely resolve the first-order and second-order moments of inertia through the balance shaft. So stationarity is inherently dominant.
The three-cylinder engine is just an embarrassing design to ensure that the volume of a single cylinder is not too small. Because the volume of the whole machine is very small, if the number of cylinders is too large, the volume of each cylinder will be too small, which will seriously deteriorate the low torque parameters. So I had no choice but to reduce the number of cylinders.
-
Three-cylinder turbocharged engines are simple to manufacture, smaller in size and lighter in weight than four-cylinder engines. But compared to the four-cylinder engine, it will still be a little worse.
-
Question: So is this what it means to buy a four-cylinder when you buy a car?
Question: I don't know anything about cars.
Thank you for your answer!

The engine of a three-cylinder car has only three cylinders, and the engine of a four-cylinder car has four cylinders; Generally, a four-cylinder engine runs more smoothly than a three-cylinder engine; If compared with engines with the same displacement, the cylinder bore of a three-cylinder engine is larger than that of a four-cylinder engine; In terms of power performance, the three-cylinder engine is larger than the four-cylinder engine.
1. The balance is not the same:
For 4-stroke engines, the main difference between a three-cylinder engine and a four-cylinder engine is that the balance is not the same.
The balance of a three-cylinder engine is not as good as that of a four-cylinder engine.
2. The ignition interval is different
The ignition sequence of the three-cylinder engine is generally 1-3-2The ignition interval angle is 240 degrees.
We know that the crankshaft angle of one stroke of the engine is 180 degrees, which means that in the adjacent ignition interval, within the 60 degree crankshaft angle, three cylinders consume power at the same time.
The ignition sequence of the four-cylinder engine is generally 1-3-4-2, and the ignition interval angle is 180 degrees. The power strokes of each cylinder are tightly connected and there is no interval.
3. Balance of crankshaft:
The three-cylinder engine adopts a three-turn crankshaft, and without taking balance measures, it can only achieve static balance, not dynamic balance.
That is, the resultant force of centrifugal force is equal to 0 when the mass system rotates, but the centrifugal moment of inertia is not equal to 0.
The four-cylinder engine adopts a 4-turn plane crankshaft, which not only has the resultant force of centrifugal inertia force of 0, but also the distance of centrifugal inertia force is equal to 0, and it can reach a state of dynamic equilibrium.
First of all, I want to say that the three-cylinder only indicates the number of cylinders of the car engine, and does not represent the quality of the car, in addition, the cylinders of the car are generally double-numbered, because it is convenient for symmetrical arrangement, I have not been exposed to the three-cylinder engine, so I don't know the three-cylinder car you said. However, the quality of the car is a big concept, including the body, the site, the engine, the circuit and many other aspects, it should be noted that the quality of the car is first based on good design, and then the level of manufacturing process, etc. Of course, the performance of the engine is a very important aspect, and the engine is as important to the car as the heart is to the human body, so when choosing a car, of course, you have to look at the engine. >>>More
Buick, Chevrolet, BMW these cars are three-cylinder engines, which can solve the problem of vibration, and can also buffer part of the pressure, so it is more stable when driving, but the driving experience is also very good, and it is safer.
We all know that engines have different cylinder counts, and the common ones are, the main difference between the structure of three cylinders and four cylinders is one less cylinder. As for the number of cylinders and displacement, the larger the displacement, the more cylinders, the greater the power. Why do we say relative? >>>More
There are many reasons why the three cylinders do not work, first check the spark plug, ignition coil, and exchange with other cylinders [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】
Specifically, you can start from the following aspects: 1. It is suspected that the oil pump is not working well, due to the damage of the check valve caused by the lack of cleaning for a long time, resulting in the reflux of residual fuel in the oil pipe after the flameout, and the system pressure is reduced. >>>More
