How long does the energy your heart need each day keep a car moving?

This is an exaggeration, in order to highlight the strength of the heart.

The energy produced by a heartbeat in a day is enough for the car to drive 30 kilometers.

The average heartbeat per minute for adult females is 78 beats per minute, while the average for adult males is 72 beats per minute.

In fact, you can't let the car run for long, but it needs a lot of energy.

Enough for a car to and from the moon.

The frequency of each person's heartbeat, that is, the number of heartbeats per minute, is different, some people are slightly faster, some people are slightly slower. Overall, women's hearts beat slightly faster than men's.

I haven't experimented with it, I don't know.

Who knows, but can't experiment.

Enough for this car to drive 30 km.

The heart relies on its own strength to beat.

Explanation: The heart doesn't need the brain's command or the rest of the body to keep beating, because the heart has its own electrical system to make it beat on its own and perform blood transfusion functions. Because of this, the heart can continue to beat for a short period of time after it has been removed from the body or the brain has died.

As long as the heart still has oxygen in it, it can beat constantly.

Expand: Knowledge about the heart.

The heart beats about 100,000 times a day. The heart is a very busy organ in the human body, beating about 100,000 times in a day, and about 3 billion beats in an average lifetime. The blood that comes out of the heart travels about 10,000 kilometers through the blood vessels, which is the distance after all the blood vessels are connected end to end.

The blood pressure value has two numbers. There are two measurements of blood pressure, systolic blood pressure (the pressure on the inner wall of the heart when it contracts) and diastolic blood pressure (the pressure that occurs when the arterial blood vessels elastically retract when the heart relaxes), commonly known as high pressure and low pressure. Normal systolic blood pressure values are less than 120 and diastolic blood pressure values are less than 80.

The heart requires energy for contraction and relaxation, and to obtain the necessary energy to perform its functions, the heart converts the chemical energy stored in fatty acids and glucose into the mechanical energy of actin-myosin interactions in myofibrils. This process consists of three parts: Substrate utilization:

Substrates mainly include fatty acids and sugars in food, as well as metabolites such as lactic acid, pyruvate and ketone bodies. In general, 60 90 of the energy required for myocardial activity comes from free fatty acids. Long-chain fatty acids are the main components of free fatty acids, which are taken up by cells and transported into human mitochondria with the help of endotoxin alkali lipphthalein transferase I (CPT-1) and enzymes.

Acetyl-CoA (CoA) is produced through oxidation and enters the tricarboxylic acid cycle; Another 10 out of 40 energy is provided by carbohydrate metabolism (glucose, lactate, ketones). After cardiomyocytes take up glucose, they produce pyruvate through glycolysis, and the uptake of lactic acid is accompanied by lactate dehydrogenase to produce pyruvate. Finally, under the action of pyruvate dehydrogenase (PDH), acetyl CoA is generated and enters the tricarboxylic acid cycle.

The respiratory chain of mitochondria produces energy: the electrons produced by the first process are transferred to oxygen through the respiratory chain complex in this process, resulting in a proton electrochemical gradient across the inner mitochondrial membrane that drives the F1F0ATP synthetase, which phosphorylates ADP to produce ATP. Transshipment and utilization of ATP:

That is, the high-energy phosphate bonds in ATP are transported to creatine to form phosphocreatine and ADP. Phosphocreatine is a molecule smaller than ATP that quickly diffuses from the mitochondria into myofibrils, where it is catalyzed by creatine kinase to regenerate ATP. Phosphocreatine is produced by the liver and kidneys and transported to the heart, where it is taken up by a special serous creatine transporter.

This process requires a 50-fold inversion of the concentration gradient. Creatine kinase catalyzes the phosphorylation of creatine in the cardiac total creatine pool of about 2 3 to produce phosphocreatine, and the remaining 1 3 remains free creatine. When energy needs exceed energy**, phosphocreatine levels drop, keeping ATP at normal levels.

This process is known as creatine kinase energy shuttling.

Therefore, the contraction and energy supply of myocardium are actually related to the above three processes.

How does oil run so fast? It's not that you're driving too fast, it's the problem.

Significant carbon deposits.

Under normal circumstances, if the car's fuel consumption suddenly increases and its power also decreases, there may be significant carbon deposits in many important locations of the car;

Don't worry at this point, take the time to go to a 4S shop or a regular repair shop to clean up the carbon deposit.

Of course, you can clean it up if you step on the accelerator until you step on four or five thousand rpm. In theory, this is possible, but the practical effect is largely negligible. So you don't have to go out of your way to remove the carbon.

Problems with vehicle sensors.

Once the sensor fails, the engine's oil-gas ratio is confused. Prior to failure, the fuel injection and intake ratio could be 1:14. When it is broken, it will become 3:14 and the fuel consumption will naturally increase.

There is a problem with the spark plug.

The spark plug, which is usually inconspicuous, is actually a very important part of the engine. If the engine is the "heart" of the car, the spark plug acts as the "pacemaker" of the engine. With the help of spark plugs, gasoline and air.

Combustion can be more complete, and the engine can remain continuous and powerful.

If there is a problem with the spark plug, it will affect the combustion of "oil and gas" in the cylinder. If the gasoline is not completely burned, fuel consumption will naturally increase and the vehicle power will decrease.

As for when it will be replaced? According to the above, for the type of spark plug to be replaced, friends can refer to their own.

In addition to these problems, it is important to be aware that these habits can also save you money on gas.

Make sure the tire pressure is normal.

If the tire pressure value is too low, the area of the tire per mu will increase, and it will bring increased safety problems. Fuel consumption will definitely increase at this time.

Of course, don't put too much pressure on the tires, which will affect comfort.

Keep your tires at reasonable pressure. If you don't know the normal tire pressure of your tires, you can look at them on the body, usually on the inside of the door or under the B-pillar.

The so-called ordinary gas stations are the gas stations of large companies, at least we can find them in any city, and the oil products of these gas stations are after-sales, and this oil is relatively small. The more fully burned, the lower the fuel consumption.

Some from the strange refueling workshop, even if it is not regular, there must be many discounts on **, but the doping of oil disturbs many impurities, and the fuel consumption will definitely be higher if it is not burned enough. Long-term use of this low-quality gasoline can also cause engine carbon deposition or other failures.

Reduce daily heavy loads.

Everyone knows that the weight of the car is lighter, and it will reduce some fuel consumption. However, some friends have long-term "equipment" in the car, so that the car will be "loaded" for a long time, and the fuel consumption of this kind of car will definitely be higher.

Some might say how much energy does it take to pull something in the car? Driving on congested roads, fuel consumption will definitely increase, so we try to choose the wrong peak trip, we can't avoid the rush hour, we have to plan the route in advance and try to choose a smoother one.

Another point, experience has taught me that it is much better to plan a "less blocked" route in advance, even if it is far away, than to be stupid to go to congestion.

After the car starts, the car computer receives the start signal, turns on the ECU (engine management computer) power supply, and the ECU begins to self-test all electronic systems of the driving system (including the engine, gearbox and basic safety systems such as ESP and airbags), and all the lights will be on the dashboard of the car. Soon, the electronic system self-test was completed and the instrument panel light was turned off.

The ECU is connected to the starter circuit, and the starter relay is turned on at the same time, the relay is engaged, and the high-voltage current is transmitted to the stator of the starter, and the starter motor begins to accelerate, driving the starter gear to rotate.

At the same time that the starting gear begins to rotate, another relay in the starter circuit is turned on, and an electromagnetic clutch is combined above the main motor of the starter, and this electromagnetic clutch controls a push rod, and the backward combination of the electromagnetic clutch will push the pull rod forward, and the pull rod is connected with the starting gear, and the starting gear is pushed forward until it is combined with the engine starting gear.

At this time, the starter starting gear has been connected to the engine starting gear, and the powerful starter begins to rotate with the engine crankshaft. On the engine side, the crankshaft rotation signal detected by the crankshaft sensor allows the ECU to start the engine process, and the engine speed begins to rise rapidly under the thick mixture.

When the engine speed rises enough to complete the start-up by its own power, the electromagnetic clutch of the ECU-controlled starter is disconnected and the starting gear is disconnected from the engine starting gear (to avoid damage to the starter due to excessive engine speed). Subsequently, the starter motor is powered off, the starter stops, and the engine relies on its own strength to complete the start, and drives the vehicle power system to drive the vehicle to run.

The operation of a car is a process of energy conversion.

The engine burns the fuel in the cylinder to do work, the chemical energy of the fuel is converted into mechanical energy, the crank connecting rod mechanism of the engine converts the reciprocating motion of the piston into the rotary motion of the crankshaft, the crankshaft is connected with the transmission through the clutch, and then the wheel is driven to rotate through the transmission shaft, the wheel is rubbed against the ground, the ground gives the wheel reaction force, the wheel rolls, and the ground moves relatively, so that the vehicle runs.

The car is driven by its own power plant, and its drive train is composed of a clutch, a transmission, a cardan drive shaft device, and a final reducer, differential and half shaft in the drive axle.

1. The car has engine power, wheels, and a steering wheel. Engine power is generated by gasoline burning in the cylinder**, pushing the piston to move, from the crankshaft to the gear, driving the wheels.

2. The reason why the car moves is also because the movement mode of the car rotates around itself, and there is also a reciprocating motion, and the one that completes a cycle after two strokes is called the two-stroke engine.

The engine with diesel fuel generally uses a fuel injection pump to inject diesel directly into the cylinder, and after mixing it with compressed air, it is automatically burned at high temperature and high pressure to produce power, which is called compression-ignition diesel engine, and these conditions are enough to make the car move.

3. There is also in the car engine, when the owner twists the car key, the electronic lighter shoots a spark, igniting the gasoline that is sprayed out and compressed in the cylinder, and the cylinder head of the engine starts to operate, and then the gear.

When the owner of the clutch is easily opened, the gears of the gearbox are connected to the axles, and the axles are connected to the wheels, and the wheels rub against the ground, and the ground gives him a reaction force, and the wheels roll and move relative to the ground, so that the car will run.

The car runs because it has an engine, and the engine burns the fuel to generate force, and then through a series of systems to transmit the force to the wheels.

A car engine is a power unit that produces power.

The clutch transmission drivetrain transmits power to the wheels.

The wheels rotate under the power drive, and the ground creates a reaction force that pushes the car forward.

Since the truck is driving normally and has not violated traffic laws, then the truck driver is not responsible.

As long as you confirm that you have no violations and the car is up to standard, you will not be responsible.

The replacement cycle of ordinary automobile spark plugs is about 30,000 kilometers.

Depending on the material of the spark plug, the replacement mileage also varies:

Ordinary copper core spark plug replacement mileage; 30,000 km;

Yttrium spark plug replacement mileage: 50,000 km;

Platinum spark plug replacement mileage: 50,000 km.

In the ignition system of a gasoline engine, a high-voltage current is introduced into the cylinder to produce an electric spark to ignite the components of the combustible gas mixture. It is mainly composed of a wiring nut, an insulator, a wiring screw, a central electrode, a side electrode and a shell, and the side electrode is welded to the shell.

The gap between the electrodes of the spark plug has a great influence on the work of the spark plug, and if the gap is too small, the spark is weak, and it is easy to leak electricity due to carbon deposits; The gap is too large, the required breakdown voltage increases, the engine is not easy to start, and it is easy to occur at high speed "lack of fire", so the spark plug gap should be appropriate, the spark plug gap used in the general battery ignition system is 0 7 0 8mm, and the individual spark plug gap can reach more than 1 0mm.

Generally speaking, under normal use, the service life of ordinary spark plugs is 30,000 kilometers, while the service life of spark plugs of advanced materials is 6 to 90,000 kilometers. Do not extend it so that it needs to be replaced at the right time.

If you find that the fuel consumption of the vehicle increases, you can consider whether to replace the spark plug, and the general repair shop will recommend replacing it after 20,000 or 30,000 kilometers, because at this time, although the spark plug is not completely damaged, the efficiency has decreased. In fact, this is determined by the quality of the spark plug, the ordinary spark plug can be changed once every 3-40,000 kilometers, and the platinum and iridium can be changed once for 6 80,000 kilometers.

Spark plugs basically serve two main functions:

A spark is generated in the combustion chamber and the mixed steam is ignited to generate power;

Seal the spark plug bore to maintain pressure inside the cylinder. In general, the high-voltage electricity supplied to the spark plug from the ignition coil through the distributor through the wire is about 20,000 to 30,000 volts, and the electrodes of the spark plug must be constantly in a high-temperature combustion chamber with an atmosphere pressure of about 45 times or more, and it must also maintain a high degree of air tightness. Therefore, in such a harsh environment, the quality and durability of the spark plug will directly affect the performance of the engine, so it must be taken seriously.
