The car s throttle controls the amount of oil per cycle of the engine , or

First, the throttle of the car is to control the amount of fuel entering the engine.

Second, just like a faucet, increase the throttle, just like the switch of the faucet is turned on a little bigger, and decreasing the throttle is to turn off a little smaller.

3. The principle of the four-stroke internal combustion engine is: to complete a working cycle within the four strokes of air intake, compression, combustion and exhaust, during which the crankshaft rotates twice. During the intake stroke, the intake valve opens and the exhaust valve closes.

The air flowing through the air filter, or the combustible mixture formed by the carburetor and gasoline, enters the cylinder through the intake pipe and intake valve; When compressing the stroke, the gas in the cylinder is compressed, the pressure increases, and the temperature rises; The combustion stroke is to inject oil and ignite before compressing the top dead center, so that the mixture is combusted, generating high temperature and high pressure, pushing the piston down and doing work; During the exhaust stroke, the piston pushes the exhaust gas in the cylinder and discharges it through the exhaust valve. After that, the intake stroke starts and the next duty cycle begins.

Fourth, the amount of oil sprayed each time directly affects the high pressure and the degree of work produced by combustion, as well as the speed of pushing.

Therefore, the throttle is the switch that controls the fuel and is the operator who controls the speed of the engine.

The throttle controls the throttle, the throttle controls the amount of air intake, and the engine injection is based on the air flow meter to detect how much air is incoming to the engine computer to control the injection.

Now the EFI engine throttle controls the air intake volume, and the fuel injection volume is computer controlled.

According to the information in Sohu.com, the advantages of diesel engines are high torque and good economic performance, and the working process of diesel engines has many similarities with gasoline engines.

The diesel engine is an engine that burns diesel fuel to obtain energy release, and was invented by the German inventor Rudolf Diesel in 1892, in honor of this inventor, diesel is indicated by his surname Diesel, and diesel engines are also known as Diesel engines.

When climbing, the engine needs to have a lot of traction, and the traction can not be achieved by increasing the power alone, which is obtained by p=fv: if you want to increase f, you can only reduce the speed When the power is the maximum, the speed is the smallest, and the traction is the largest.
