Water-cooled cylinderThe cylinder block of the motor and the upper crankcase are often cast into one, which is called the cylinder block - the crankcase, also known as the cylinder block.

What is the difference between Honda's i-VTEC engine and Earth Dream engine?

I-VTEC is an Earth Dream, which belongs to a series of Honda engines. The full English name of I-VTEC is: (variable valve timing and lift electronic control system), and the Chinese name is (variable valve timing and lift electronic control system).

I-VTEC is the Earth Dream, which belongs to the Honda engine series. I-VTEC is called variable valve timing and lift electronic control system in English, and variable valve timing and lift electronic control system in Chinese. The I-vtec system first appeared in 1989. Its inventor is Kenichi Matsuzawa.

Is i-vtec an earth dream? I-VTEC is an earth dream, which belongs to a series of Honda engines. The full English name of I-VTEC is: (variable valve timing and lift electronic control system), and the Chinese name is (variable valve timing and lift electronic control system).

This Earth Dream engine adopts technologies such as in-cylinder direct injection, i-vtec, variable intake manifold technology, high compression ratio and lightweight cylinder, so the performance of the engine is very strong.The essence of Honda Earth Dream Engine is still on i-vtec. The working details of the engine are very complicated.

Honda Witec engine and Earth Dream engine are different in materials; Engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engine (resurrection plug engine), external combustion engine (Stling engine, steam engine, etc.), jet engine Machine, electric motor, etc.

working principle of automobile engine

1. The reason why the engine continuously provides power is due to the orderly cycle of the four strokes of air intake, compression, work and exhaust in the cylinder. Intake stroke: When the piston moves from the upper stop point to the lower stop point in the cylinder, the intake valve opens, the exhaust valve closes, and the mixture of fresh air and gasoline is sucked into the cylinder.

2. The working principle of engine 1. Intapt stroke When the intake valve opens and the exhaust valve closes, the piston moves from the upper stop to the lower stop. The volume of the cylinder above the piston increases, resulting in a vacuum degree, and the pressure in the cylinder drops below the intake pressure.

3. Cars include gasoline engines and four-stroke diesel engines. Their working principle is as follows: The working principle of gasoline engine: the four-stroke gasoline engine first mixes air and gasoline in a certain proportion into a good mixture, and then sucks the mixture into the cylinder during the intake stroke. The mixture is compressed and ignited to produce heat energy.

4. The working principle of automobile engines is mainly to convert chemical energy into mechanical energy. The reason why the engine has sufficient power is that by burning the fuel in the cylinderGenerate kinetic energy, which makes the piston in the engine cylinder reciprocate, which is also a process of working cycle.

5. Working principle of automobile engine: by burning the fuel in the cylinder to generate kinetic energy, it drives the reciprocating movement of the piston in the engine cylinder, thus driving the connecting rod connected to the piston and the crank connected to the connecting rod, making a reciprocating circular movement around the center of the crankshaft, and outputting power.

What is the reason for the engine shaking?

The throttle valve is too dirty or the fuel nozzle accumulates too much carbon, and there is a problem with the ignition system. For the problem of the ignition system, it is necessary to check the working condition of the spark plug, high-voltage conductor and ignition coil. The poor operation of the ignition system and the poor condition of the spark plug jumping will also lead to such failures. Too much carbon needs to be cleaned up in time.

Seven reasons for engine jitter are abnormal water temperature: the operating temperature of the engine has a normal range. If the water temperature is high, the ignition time will be earlier, the oil-gas mixing ratio will change, the oil viscosity will become thinner, and the lubrication performance will deteriorate.

The air filter is blocked. The main function of the air filter is to protect the engine and reduce wear. In general, the owner needs to replace it after a certain mileage. If moreIf it is not replaced in time, it may cause insufficient air intake, which will cause the car engine to shake during use.

The most common reason for car shaking is that the throttle valve is too dirty or the fuel injector has too much carbon.

What's wrong with the shaking of the Passat engine?

1. Too much carbon accumulation in the throttle valve, fuel injector and intake duct may cause serious start-up shaking of the car. There is too much carbon accumulation inside the engine, and the gasoline sprayed by the start-up fuel injection head will be absorbed by a large amount of carbon accumulation, resulting in the start-up mixture gas being too thin, causing the start-up shaking.

2. The engine carbon accumulation is serious. The most common cause of idling jitter is excessive carbonisation of the throttle valve or fuel nozzle.

3. Severe idling jitter of Passat may be caused by the following problems: serious engine carbon accumulation, ignition system problems, unstable oil pressure, and aging engine parts. The engine has serious carbonization. The most common cause of car shaking is too dirty throttle or too much carbon in the fuel injector.

4. Causes of engine shaking: the engine foot glue is aging or loose. The foot glue is the glue block. Its function is to reduce the vibration and buffering of the engine during work, and to fix the engine. Once these foot glues are aging or loose, the vibration of the engine will be abnormally obvious.

5. The common fault points are as follows: intake manifold or various valve leakage. When the air intake of the engine is not right, the mixture will be too thick or too thin, causing the engine to burn abnormally. It will cause the engine to shake at idle speed.

6. The intake manifold or various valves leak. When the intake of the engine is not right, the mixture will cause the mixture to be too thick or too thin, causing the engine to burn abnormally. It will cause the engine to shake at idle speed. When the air leakage position affects the vacuum of the engine, the engine will shake violently, which has a greater impact on the idling speed of the cold car.

What is the phenomenon and cause of engine death?

1. There are two situations where the engine is dead: the piston and the cylinder liner are dead. Causes: The engine high temperature caused by serious lack of cooling water, jamming of the thermosulator, damage to the fan tape, lack of lubrication in the cylinder wall, etc. If the crankshaft and the bearing are dead, the tile will be burned.

2. Most of these reasons are caused by lack of oil or poor oil lubrication.However, there are also parts damaged due to other reasons, causing the engine to be stuck and unable to run, so it is not all caused by lack of oil or poor oil lubrication, it depends on the specific situation.

3. The dead crankshaft of the car engine will cause the car to turn off, which is over. Reason for death: poor lubrication conditions of the engine: engine tile, in many cases, it is caused by poor lubrication of the oil. Now the working conditions of the engine of the truck are relatively poor; it is easy to have large heat load and high temperature of the engine.
