How does the engine adjust the power generation

The generator of a car is directly driven by the engine, and the engine speed fluctuates greatly. It is basically possible to change from a few hundred to nearly ten thousand revolutions. Recent updates Of course, the generator must have an adjustment mechanism to ensure the output of electricity and medical certification. But when you step down the accelerator, the voltage soars, and the car's circuit is paralyzed in an instant. How to adjust the power generation? The answer is to adjust the strength of the generator's magnetic field. As mentioned in junior high school physics, the generator relies on the coil to cut the magnetic induction line to generate electricity. The faster the cutting speed (rotation speed), the higher the magnetic field strength, the higher the voltage. We can't adjust the speed, but we can only adjust the magnetic field strength. When the output voltage of the generator is low, the voltage regulator energizes the excitation coil, adding magnetic field strength to increase the output voltage. When the output voltage is too low, the voltage regulator will energize the excitation coil and increase the magnetic field strength to increase the output voltage. When the output voltage is low.

The malfunction caused by the ECU of the electronic control engine computer

The electronic control engine computer ECU cannot monitor the failures caused by the following reasons. (1) Generally, the ECU of low-end cars cannot monitor the failure of the high-voltage ignition circuit caused by the inoperative ignition coil, the polluted or damaged spark plug, and the broken core of the high-voltage line. (2) ECU cannot monitor the blockage of the inlet filter of the electric gasoline pump, the fuel filter pipeline, and the failure of the incoming fuel caused by the flattening of the fuel inlet pipeline or the return pipeline. Smooth, or the mixture is too thin. Loose rearview mirror in Mercedes-Benz car (3) The ECU cannot monitor the air filter inlet or the air filter plugging or throttling. The solution to the failure or vibration caused by the change of the air flow rate. Product brand summary Commonly used accessories for Mercedes-Benz maintenance and repair (4) ECU cannot monitor the high or low cylinder pressure, or the uniformity of each cylinder pressure (5) ECU cannot monitor the plug and the pins are damaged, but it will produce fault codes caused by this situation (6) ECU cannot monitor the bad grounding, but it will produce fault codes caused by this situation (7) ECU cannot monitor the leakage or throttling of the vacuum line of the vacuum booster in the engine control system. However, the vacuum degree of the absolute pressure sensor of the intake manifold will be monitored and the ECU will also record the fault code. The above 10 items are the causes of failures that cannot be detected by the electronic control engine, which should be paid attention to when repairing the electronic control engine. Whether it is an electronic control failure or a mechanical failure, the location and performance characteristics of the occurrence must be correctly distinguished in order to accurately and quickly determine and eliminate the failure During the inspection, if the engine is faulty and the engine fault warning light is not lit (the fault code is not displayed), it means that the engine fault may be in the mechanical part.

Function and composition of engine block group

Body group function The body group is the support of the engine, and is the assembly base of the crank connecting rod mechanism, the valve mechanism and the main components of the engine systems. The cylinder head is used to close the top of the cylinder and form a combustion chamber together with the top of the piston and the cylinder wall. In addition, the water jacket, oil passage and oil pan in the cylinder head and body are the components of the cooling system and lubrication system respectively. Body group composition structure Modern automobile engine block group is mainly composed of block, cylinder head, cylinder head cover, cylinder liner, main bearing cover and oil pan. For engines with cylinder liners, the body group also includes dry or wet cylinder liners.
