[0002] Fuel engines are generally used in traffic equipment such as automobiles. Those skilled in the art know that the fuel supply of fuel engines (especially gasoline engines) is determined according to the intake air near the fuel injector. The larger the intake air, the greater the torque of the engine. In the prior art, the turbocharger method is used to increase the intake pressure at an appropriate time or under all working conditions, thereby increasing the engine torque. The turbocharger uses the exhaust gas pressure as the power source, and the exhaust pipe The exhaust gas turbine installed at the exhaust gas turbine is connected with the intake turbine installed at the intake manifold to make them synchronized, and the exhaust gas pressure is used to drive the intake turbine to rotate to increase the intake pressure at the intake manifold. Although this method is mature , but it also brings certain side effects and defects, such as the increase of exhaust gas exhaust resistance, resulting in incomplete exhaust exhaust, more exhaust gas residues in the combustion chamber, the negative pressure of the intake air in the combustion chamber is affected, and more combustion residues. There is a lot of carbon deposits. Although the exhaust gas recirculation is beneficial to the complete combustion of the dye, it is obviously not an ideal structure to increase the exhaust resistance, because it affects the exhaust gas discharge frequency and the back pressure on the exhaust valve. Moreover, when the turbocharger works, it is generally under high-speed engine operating conditions, and the necessity of exhaust gas recirculation is low under this operating condition; the high temperature of the exhaust gas has extremely high requirements for the shaft-connected rotation between the exhaust gas turbine and the intake turbine, making the turbine The supercharger is extremely expensive and has a short service life

[0003] Existing conventional engines use exhaust valves and intake valves to intermittently communicate and cut off the combustion chamber, exhaust manifold and intake manifold, and the knocking frequency between the valve and the cylinder block is extremely high, and the knocking The wear caused by the impact process will change the size of the combustion chamber space and affect the air tightness. Valve leakage is a routine fault after the engine has been used for a period of time. The high temperature of the combustion chamber affects the valve lubrication and the reliable service life of the valve. Engine Flaws and Illnesses
