What items can improve the engine condition of the car maintenance?

In fact, the key to improving the engine state is the engine oil, and it is good to replace high-quality engine oil with small maintenance. In the past, when I used the original engine oil in the 4S shop, the power was also poor, and the throttle was relatively heavy. After the insurance, I changed the GT Magic Red engine oil in the maintenance shop, and the driving experience was obviously different.

Up to now, it has been used for 70,000 or 80,000 kilometers, and the engine has been in good health. Therefore, the difference between good engine oil and low-end engine oil is still large, and it is obvious that you can change it for two days.

The items of car maintenance mainly include changing the engine oil, changing the oil filter, replacing the air filter, and replacing the air filter. The specific operation items are as follows:

1. Replace the air filter.

The engine sucks in a lot of air during operation, and if the air is not filtered, the dust in it will accelerate the wear of the piston group and cylinders. Larger particles enter between the piston and the cylinder, which can also cause a serious "cylinder pulling" phenomenon. The function of the air cleaner is to filter out dust and particles in the air and ensure that sufficient and clean air enters the cylinder.

2. Replace the gasoline filter.

The function of the gasoline filter is to provide clean fuel to the engine and filter out the moisture and impurities of the gasoline. This optimizes engine performance and provides the best possible protection for the engine.

3. Replace the oil filter.

The oil filter is clogged and will hinder the flow of lubricating oil, so that the engine is poorly lubricated, wear and tear is increased and even burned tiles, etc., usually replaced every 8000km, if the weather is dry. It should be shortened to 5000km and replaced once.

Dabao's project:

Replacement: steam filter, air filter, machine filter, air conditioning filter (if needed).

Maintenance and inspection: four-wheel brake system, parking brake system.

Inspection: chassis bolts, four-wheel and spare tire pressure, valve clearance of various electrical appliances in the car (if adjustable).

If you feel that the car is underpowered: clean the throttle valves, idle valves (if equipped), fuel injectors, air intakes, check the spark plugs (and replace them if necessary).

Use the minimum oil of the specified load specification, but also use the oil with the smallest viscosity of 100° movement, so that the engine is much lighter, you may have more oil.

1. Regularly change the engine oil: the engine oil is the lubricant of the engine, which can lubricate, clean, cool, seal, reduce wear and other functions of the engine, and is also the "blood" of the engine. Failure to change the oil for a long time can lead to severe wear and tear on engine parts, reducing the life of the engine.

The manufacturer recommends replacing it every 5,000 or 10,000 kilometers. Therefore, when it comes to choosing a motor oil, it is necessary to choose a good quality.

2. Regularly change the three filters: the three filters refer to the air filter, oil filter and gasoline filter. The three filters can provide the engine with the effect of filtering impurities, protect the engine, and also improve the working efficiency of the engine.

The regular maintenance interval of the three filters is the same as that of the engine oil.

3. Battery: The battery is used to ensure that the engine can start normally, and the color of the "electric eye" should be checked in the observation window at the upper part of the battery to see whether it is green. The battery life is generally about two years, and the life may be shorter in cold weather.

4. Brake fluid: Brake is very important for driving safety, brake fluid has strong water absorption, can automatically absorb moisture in the air. Therefore, it is necessary to check the level of brake fluid regularly, and add or replace it in time if it is lower than the standard value.

5. Coolant: The coolant is to ensure the normal operation of the engine, and it is necessary to regularly check whether the coolant level is at the standard value, and regularly check whether the coolant pot is leaking, and the coolant needs to be replaced once a year on average. How do you add coolant?

6. Power steering fluid: Power steering fluid is commonly known as direction oil, and it is necessary to regularly check whether there is any leakage or obvious abnormal noise. Electronically assisted models are maintenance-free, so there is no need to change the steering oil. The maintenance interval of directional oil is about 60,000 kilometers.

Hello, if it is the first warranty, you only need to change the oil.

After buying a new car, you need to change the oil filter, air filter, and air conditioning filter once a year every six months or one year.

Generally, you need to change the spark plug for three years, you need to change the coolant, transmission oil, brake fluid for four years, you need to check the brake brake pads, brake discs, and you need to change the timing belt, water pump belt, tire change, etc.

If you do it according to the maintenance hand, some items can be delayed, and there is no so-called size maintenance.

In other words: small maintenance is often needed to do, which costs less money, and major maintenance is the maintenance that the car can not do several times after buying, which costs a lot of money.

Generally, when you go to the 4S shop for maintenance, they will check it.

An engine is a machine that converts a certain form of energy into mechanical energy. Its function is to convert the chemical energy of liquid or gas into heat energy after combustion, and then convert the heat energy into mechanical energy through expansion and output power. The power of the car comes from the engine.

The engine is the heart of the car, providing power for the walking of the car, and the power, economy and environmental protection of the car. To put it simply, the engine is an energy conversion mechanism, that is, the thermal energy of gasoline (diesel) is converted into mechanical energy by pushing the piston to work when the combustion gas expands in the sealed cylinder, which is the most basic principle of the engine. All the structure of the engine is for the energy conversion service, although the engine has gone through more than 100 years of history with the car, whether it is in the design, manufacturing, technology or the tung type in the performance, control has been greatly improved, its basic principle is still unchanged, this is a rich creative era, those engine designers, constantly the latest technology and the engine into one, the engine into a complex mechatronics product, so that the engine performance to the extent of nearly perfect, The world's famous automobile manufacturers will also take the performance of the engine as a competitive highlight, first, the role of the automobile engine.

The automobile engine is a device that provides power for the car, is the heart of the car, and is an energy conversion device, which is used to convert the thermal energy of gasoline (diesel) into mechanical energy by expanding the gas after combustion in the sealed cylinder bureau, pushing the piston to do work. According to different power**, automobile engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrids.

Second, the classification of automobile engines.

1. According to the working mode of the air intake system, it can be divided into four types: naturally aspirated, turbocharged, mechanically supercharged and double supercharged.

2. According to the piston movement mode, it can be divided into two types: reciprocating piston internal combustion engine and rotary piston engine.

3. According to the cylinder arrangement, it is divided into in-line engines, V-shaped engines such as engines, W-type engines and horizontally opposed engines.

4. According to the number of cylinders, it can be divided into single-cylinder engine and multi-cylinder engine. Modern cars mostly use three-cylinder, four-cylinder, six-cylinder, and eight-cylinder engines.

5. According to different cooling methods, it can be divided into water-cooled engine and air-cooled engine. The water-cooled engine cools evenly, works reliably, and has a good cooling effect, and is widely used in modern automotive engines.

6. According to the number of strokes, it can be divided into four-stroke internal combustion engine and two-stroke internal combustion engine. Four-stroke internal combustion engines are widely used in automobile engines.

7. Classified according to the way of fuel: carburetor engine and EFI engine and in-cylinder direct injection engine.

The following situations of the engine need to be overhauled: 1. The gap between the piston and the cylinder wall is too large and the blue smoke is emitted, which must be overhauled. 2. The engine emits serious black smoke.

Measured by a cylinder pressure gauge, if the cylinder pressure is lower than normal, it must be overhauled. 3. There is abnormal sound in the operation of the engine. When there is an abnormal noise in the engine, the air commesis town should be determined by dismantling, or measured with an engine abnormal noise detector.

4. The small and small tiles of the engine are seriously burned and the crankshaft is seriously worn. 5. There was the sound of pulling the cylinder, and through the dismantling of the engine, it was found that the live bucket was coarse and the cylinder wall was seriously strained.

Yes, the detailed orange type of engine maintenance has the following pretense;

1. Engine cleaning and maintenance.

2. Fuel intake system cleaning.

3. Three-way catalytic cleaning of Sun Wu stove.
