Problems solved by technology

The gas distribution system of the existing valve shaft type engine cannot control the gas flow direction and flow rate when the gas is taken in. After the gas enters the combustion chamber, an orderly air flow field cannot be formed, resulting in poor combustion conditions, high fuel consumption, poor emissions, and poor power performance. High pump air loss, slow response

Abstract

The invention discloses a gas distributing shaft motor gas distributing system and a corresponding motor and a corresponding automobile. The gas distributing shaft motor gas distributing system comprises a cylinder cover, a gas distributing shaft and a power wheel, wherein the gas distributing shaft penetrates through the cylinder cover transversely, the power wheel is fixedly connected with one end of the gas distributing shaft and drives the gas distributing shaft to rotate, gas inlet ducts and gas outlet ducts are distributed on the cylinder cover in the axial direction of the gas distributing shaft at intervals, gas inlet channels corresponding to the positions of the gas inlet ducts and gas outlet channels corresponding to the positions of the gas outlet ducts are distributed on the gas distributing shaft in the axial direction at intervals, the gas inlet channels and the gas outlet channels are not arranged in parallel, and a control valve used for changing the section of the air inlet of each air inlet channel so as to change air inlet flow is arranged inside each air inlet channel. According to the gas distributing shaft motor gas distributing system, the control valves are capable of changing the air inlet sections of the air inlet channels and accordingly controlling the air inlet flow entering a combustor, meanwhile, gas is made to form a flow field inside the combustor, the number of parts of the gas distributing shaft motor gas distributing system is reduced, the rotating speed of the motor is increased, and cost of the motor is reduced. The gas distributing shaft motor gas distributing system is suitable for various motors and further capable of being used for various automobiles.

Description

technical field [0001] The invention belongs to the technical field of motor vehicles, and relates to a valve shaft type engine gas distribution system, an engine and an automobile with the system. Background technique [0002] The traditional engine gas distribution system is mainly composed of cylinder head, valve, valve spring, tappet, rocker arm, rocker shaft, camshaft and timing mechanism. There are many transmission parts and complex mechanical structure. As a result, the parts wear fast, the operation noise is large, and a certain amount of power is required to overcome the resistance of the valve spring to drive the valve to move. Therefore, the cam valve type valve mechanism has a high failure rate, short maintenance period, and high power loss. [0003] The gas distribution system of the gas distribution shaft type engine is mainly composed of a cylinder head, a gas distribution shaft that runs through the cylinder head, and a power wheel that drives the gas distri...
