Problems solved by technology
[0002] The well-known four-stroke internal combustion engine in the low power output state, in order to realize the Miller cycle, will use the valve adjustment mechanism to reduce the opening lift and opening time of the valve to achieve the purpose of reducing the intake air. The opening lift of the valve will increase the resistance of the intake air. At the same time, reducing the opening time of the valve will cause a part of the piston to be in an idling state. These two aspects will lead to an increase in the pumping loss during the intake phase.
In the state of high power output, it is in the Otto cycle state. Since both the compressed air and the expansion work are performed in the same internal combustion engine cylinder, the compression ratio is equal to the expansion ratio. Taking gasoline internal combustion engines as an example, considering the knock characteristics of gasoline, compression The ratio is generally limited to about 10:1, and it is impossible to further improve fuel efficiency by increasing the expansion ratio
The well-known four-stroke internal combustion engines must use specific fuel grades to meet the working conditions, resulting in increased fuel costs

Embodiment Construction
[0012] The use of a complete working process of an air precompression internal combustion engine device of the present invention Figure 2 to Figure 4 To illustrate.
[0013] First, if figure 2 As shown, in the working exhaust chamber 3, the piston 2 crosses the bottom dead center 11 and moves upward to enter the exhaust stroke, the exhaust valve 9 is opened, the side-opening high-pressure valve 4 is closed, and the exhaust gas is discharged through the exhaust valve 2. At the same time, in the combustion chamber 4, the high-pressure air valve 6 is opened, and the high-pressure air is injected into the combustion chamber, and the fuel is injected into the fuel synchronously through the fuel injection valve 7 to form an air-fuel mixture. closure.
[0014] Next, if image 3 As shown, in the power exhaust chamber 3, the piston 2 approaches the top dead center 6 at a specific moment, and in the ram combustion chamber 4, the spark plug 8 activates the ignition, ignites the air-...

Background technique [0002] The well-known four-stroke internal combustion engine in the low power output state, in order to realize the Miller cycle, will use the valve adjustment mechanism to reduce the opening lift and opening time of the valve to achieve the purpose of reducing the intake air. The opening lift of the valve will increase the resistance of the intake air, and at the same time reduce the opening time of the valve, which will cause a part of the piston to be in an idling state, both of which will lead to an increase in the pumping loss during the intake phase. In the state of high power output, it is in the Otto cycle state. Since both the compressed air and the expansion work are carried out in the same internal combustion engine cylinder, the compression ratio is equal to the expansion ratio. Taking gasoline internal combustion engines as an example, considering t...
