How does the engine work? How does the engine work?

1. Basic theory: The gasoline engine converts the energy of gasoline into kinetic energy to drive the car. , the easiest way is to gain kinetic energy by burning gasoline inside the car engine.Therefore, the car engine is an internal combustion engine - combustion occurs inside the engine.

2. Only the engine can run by itself, and the work cycle can proceed automatically. Therefore, the whole process of crankshaft starting to rotate under the action of external force until the engine begins to idle automatically is called the start-up of the engine. The device required to complete the start-up process is called the starting system of the engine.

3. High-temperature and high-pressure gas acts on the top of the piston, pushing the piston to make a linear reciprocating movement, and the mechanical energy is output out through the connecting rod, crankshaft and flywheel mechanism. The four-stroke gasoline engine completes a working cycle in the intake stroke, compression stroke, workingstroke and exhauststroke.

4. Diesel engine, first the oil line pumps the fuel out of the fuel tank through the fuel pump, and then enters through the fuel filter.Low-pressure pipe, the fuel enters the fuel injector from the low-pressure pipe, and then enters the fuel injector from the high-pressure pipe. The fuel injector injects the fuel into the cylinder block, and then the fuselage is compressed, and the engine begins to work.

5. How does the car engine work? The gas pressure generated by fuel combustion directly acts on the top of the piston, pushing the piston up and down. Through the piston, the connecting rod and the crankshaft, the reciprocating linear motion of the piston is converted into the rotational movement of the crankshaft, so that the crankshaft drives the flywheel to rotate, producing a strong The torque force.

6. Engine working process: air intake-compression-fuel injection-combustion-expansion work-exhaust. An engine is a machine that can convert other forms of energy into mechanical energy. It was first born in the United Kingdom. It is suitable for both power generators and the whole machine including power generators.Air intake stroke The quality that enters the cylinder is pure air.

Detailed process of car engine start-up

1. After starting , put the gear in D gear, slowly release the brake, and the vehicle will move forward. If it is a manual transmission, you need to step on the clutch beforeStart the engine, then put it in 1st gear, slowly release the clutch, and move your right foot from the brake pedal to the accelerator pedal, and refuel slightly. The throttle and clutch are used together, and the vehicle moves forward slowly.

2. When the car engine enters the working state from a stationary state, the engine must be rotated with the help of external force, so that the mixed gas combustion and expansion work cycle in the cylinder can run automatically. Under the action of external forces, the process of the engine crankshaft from the beginning of rotation to the idling operation is called the start-up process of the engine.

3. The correct way to start the engine is: when starting, turn the ignition key to the on position, wait for 58s, and then turn the key to the start position to start the engine.

4. And starting a car is also the first step to drive.The following will introduce the steps of starting the car in detail. After inserting the key, gently swir the key to connect it to the ignition system. When the key is stwed to the last position, the ignition system of the vehicle will start. If you find that the ignition fails, you can try to turn the key again.

5. Do you know the start-up process of the engine? When the key is turned on to the ON position, the ECU is energized. After the ECU is energized, the corresponding sensor is powered on through each pin and the sensor information is obtained to control the engine operation. At the same time, the gasoline pump in the fuel tank is energized for 3-5 seconds to provide sufficient pressure on the oil supply system.

6. Continue to turn the key to on (if the key can't be turned on, it is likely that the steering wheel is locked. While gently turning the steering wheel, just squee it), and then stop waiting for 6-10 seconds to let the oil pump relay close.Start the engine, and then observe whether the indicator light of the instrument is normal.

How to start the car? The correct ignition steps of the car (engine start method)

1. After the key is inserted into the ignition switch, stay in each gear for about 1 or 2 seconds. At this time, you can hear the sound of the electrical equipment being energized, and then enter the next gear. Some cars can go directly to the ON position, and then wait for all aspects of the electrical appliances to start in all directions for about 6-7 seconds, and then turn the key to the START state to ignit directly.

2. The correct way to start the engine is: when starting, turn the ignition key to the on position, wait for 58s, and then turn the key to the start position to start the engine.

3. There is no problem after self-examination, that is, after all the instruments are turned off, then turn the key to start. At this time, follow the normal startup operation steps. For some one-click start vehicles, there is actually also a self-inspection operation method. Specifically, press the button directly without stepping on any pedal, and the vehicle will enter the self-inspection process.

4. The method of igniting the car in extremely cold weather is as follows: 1 Check the battery. There is a button battery-sized inspection window to indicate the battery status. If it is green, it means that the battery power is more than 50%. You can rest assured to try to ignite it once or twice. 2 If you raise the engine temperature, you can light the stove and bake it under the engine. Engine 3 increases the ignition probability 4.

5. Observe the surrounding environment of the car. Before driving, go around the car to see if there are obstacles around the car, whether there are pedestrians on the driving track, and whether the road ahead is clear.

The three basic processes of starting the engine?

The starter uses three parts to realize the whole startup process. The DC series motor introduces the current from the battery and makes the drive gear of the starter produce mechanical movement; the transmission mechanism meshes the drive gear into the flywheel ring, and can automatically detach after the engine starts; the starter circuit is controlled by an electromagnetic switch.

Engine start-up can be divided into three stages: the stage of establishing fuel injection pressure; the engine control unit judgment cylinder ignition stage; and the successful ignition conversion to idle stage.

First, connect a thick wire from the positive pole of the battery and connect it to the empty screw of the iron suction switch of the starting motor.Column, there are two thickest studs on the iron suction switch. Take a closer look at one of the studs that has connected a wire to the interior of the starting motor. The wrong pole wire is connected to the unused stud.

Use the key to turn the ignition switch to ON gear (the previous gear to start), the instrument is energized, and the car is ready to start after a few seconds. ( 2) Turn on the SRART gear of the ignition switch, and turn on the circuit of the battery and the start-up system.

The process of starting the engine can be briefly summarized into four steps: air intake, compression, ignition and exhaust. First, the engine is started by a battery or starter, and the air is sucked in from the air filter. At the same time, gasoline is transported from the gasoline pump to the fuel tank to form a fuel-air mixture for air intake.
