Anonymous users2024-02-14The working process of the diesel engine: The four-stroke engine is a piston reciprocating four strokes to complete a working cycle, including four processes: air intake, compression, work and exhaust. The four-stroke diesel engine goes through the same process of air intake, compression, work and exhaust as the gasoline engine.
But the difference with the gasoline engine is that the gasoline engine is ignited, and the diesel engine is compression-ignited.
[Introduction]: A diesel engine is an engine that burns diesel fuel to obtain energy release. It was invented in 1892 by the German inventor Rudolf Diesel, and in honor of the inventor, diesel is represented by his surname Diesel, and diesel engines are also known as diesel engines.
Features]: The advantages of diesel engines are high torque and good economic performance. The working process of a diesel engine has many similarities with a gasoline engine, and each working cycle also goes through four strokes: air intake, compression, work, and exhaust.
However, because the fuel used in diesel engine is diesel, its viscosity is greater than that of gasoline, it is not easy to evaporate, and its spontaneous ignition temperature is lower than that of gasoline, so the formation and ignition of combustible mixture are different from those of gasoline engine. The main difference is that the mixture in the cylinders of a diesel engine is compression-ignited, not ignited. When the diesel engine is working, it is air that enters the cylinder, and when the air in the cylinder is compressed to the end, the temperature can reach 500-700, and the pressure can reach 40-50 atmospheres.
When the piston is close to the top dead center, the fuel injector of the fuel supply system injects fuel into the cylinder combustion chamber in a very short time with extremely high pressure, the diesel oil forms fine oil particles, mixed with high-pressure and high-temperature air, the combustible mixture burns by itself, violently expands to produce explosive force, and pushes the piston down to do work, at this time the temperature can reach 1900-2000, the pressure can reach 60-100 atmospheres, and the torque generated is very large, so the diesel engine is widely used in large diesel equipment.

Anonymous users2024-02-11The oil pressure and the cylinder barrel are not related, the oil pressure is mainly involved, the relationship between the oil pump, the main shaft bearing, the main oil channel safety valve connecting rod bearing and the sub-bearing bearing is very small, it is recommended that you remove the oil bottom to see if the collector of the oil pump has any stolen goods

Anonymous users2024-02-07If you can be sure that the nozzle is stuck, it is a problem of oil quality, but the fuel injection pressure of the fuel nozzle of the EFI is very high, and the oil quality will not be so easy to jam the nozzle, are you misjudged, is the injector seriously depressurized, or the solenoid valve is burned out.

It's hard to start just these few things, the ignition timing is not accurate, the motor is weak, the cylinder pressure is insufficient and difficult to catch fire, your car has been a few years, and you haven't said it, whether it started like this or slowly, you didn't make it clear, but I want to remind you that the usual driving habits are also very important, step on the clutch and hit the motor when the car is cold in the morning, so that the motor will not drive the gearbox to turn, If you are really in a hurry to get on the road, you must stabilize the throttle with the first gear as far as possible (about 200 meters), Because in the morning, the oil has been refluxed to the oil pan after a night of precipitation, and it is slow because it is good for the oil pressure, and all parts of the machinery have not been fully lubricated, and the water temperature is a little higher and then pull the high speed, which is very good for the service life of the engine. >>>More
Petrol or diesel engine for EFI?
Among the two major institutions and the five main components of the system of electronically controlled diesel engine and traditional diesel engine, the fuel system is quite different. The traditional diesel engine uses a mechanical oil pump to pressurize the diesel fuel and then inject it into the cylinder through the injector, and the injection pressure and injection time cannot be controlled with the different working conditions of the engine; For the electronically controlled diesel engine, a set of electronic control system has been added, mainly including ECU, common rail pipe, high-pressure oil pump, etc., the common rail pipe is mainly used to store high-pressure diesel, play a role in stabilizing pressure, and ensure that the injection pressure of the engine is relatively stable under different working conditions; By calibrating the rail pressure, advance angle and other parameters, it ensures that the engine has sufficient power and the lowest fuel consumption under different working conditions. >>>More
1) The four-stroke gasoline engine mixes air and gasoline in a certain proportion to form a good mixture of automobile engines. In the intake stroke, the mixture is sucked into the cylinder, and the mixture is compressed, ignited, and burned to produce heat energy. The high-temperature and high-pressure gas acts on the top of the piston to promote the piston to do linear reciprocating motion, and the mechanical energy is output outward through the connecting rod, crankshaft and flywheel mechanism. >>>More
The landlord, the battery has many functions after the car starts, such as the electrical appliances of the whole car depend on him, such as headlights, instrument lights, tail lights, glass regulators and so on. Because after the car starts, the generator starts working, and the output of his alternating current is very unstable. The generator alone cannot supply the electrical appliances of the car, so the designers directly charge the electricity from the generator to the battery through the rectifier regulator, and then the battery supplies power to the electrical equipment of the whole car. >>>More
