Embodiment Construction

[0012] In the first embodiment shown in Figure 1, the intake valve (8) and the exhaust valve (7) are installed in the intake and exhaust passages of the engine cylinder head (9) respectively, and the camshaft (2) is installed in the intake and exhaust valves. Above, the outlets of the cylinder head intake and exhaust ducts are distributed on both sides of the cylinder head, and the intake duct (1) is installed outside the intake duct, which is connected with the cylinder head intake duct, and the control valve assembly (6) is installed outside the cylinder head exhaust duct. The exhaust pipe (4) is installed outside the control valve assembly (6), and is connected with the exhaust channel of the control valve assembly (6), and one end of the intake branch pipe (3) is installed outside the control valve assembly (6). And be connected with the intake passage of control valve assembly (6), the other end is connected with intake pipe (1), because the temperature of exhaust is very ...

Abstract

This invention relates to motor compound gas-in system, wherein, the gas cylinder channel is fixed with gas-in tube and control valve bus connected with discharge tube and with discharge channel; the control valve bus gas-in channel is connected to gas-in tube; the control valve bus discharge channel is fixed with one gas control valve and discharge control valve through screw tube to control switch between discharge tube and channel; at end of motor discharge, discharge door and control valve closes and the gas-in door opens.

Description

Technical field [0001] The invention relates to an engine composite intake system, which can significantly improve the charging efficiency of the engine, enable the engine to be filled with more charge under the same conditions, and improve the power performance, economy and emission level of the engine. Background technique [0002] At present, the intake and exhaust system of a naturally aspirated engine for automobiles is usually mainly composed of an intake pipe, an exhaust pipe, a cylinder head, an intake valve, an exhaust valve and a camshaft. When the engine is working, the intake valve opens during the intake stroke, and a certain degree of vacuum is generated in the cylinder due to the movement of the piston. And after the power stroke, the exhaust valve is opened, and the exhaust gas is discharged through the cylinder head exhaust port and exhaust pipe through the movement of the piston. Since the speed of the automobile engine is usually several thousand revoluti...
