Abstract

The invention relates to a device for improving surface smoothness of air inlet and outlet channels of a combustion motor cylinder cover. The device comprises an air compressor pump 1, a gas feeding pipeline 4, a shot blasting storing container 6, at least one spray gun 8, at least one nozzle 9 and an air cylinder cover 10, wherein the air cylinder cover is arranged on an air cylinder cover placing platform 11, and the air compressor pump 1 is connected with the spray gun 8 through the gas feeding pipeline 4; and the shot blasting storing container 6 is connected with the spray gun 8 which is connected with the nozzle 9, the nozzle 9 stretches into the air cylinder cover 10, an air inlet channel or an air outlet channel of the air cylinder cover 10 is aligned, and the air cylinder cover placing platform arranged below a valve base of the air cylinder cover 10 is provided with a through hole. The device is used for processing the air cylinder cover and has the cleaning function, the surface smoothness of the air outlet channel is improved, and improvement of the consistency of the air incoming of all cylinders of an engine is facilitated. The invention also discloses a method for improving the surface smoothness of the air inlet and outlet channels of the combustion motor cylinder cover.

Description

technical field [0001] The invention relates to a device and a method for improving the surface smoothness of the intake and exhaust channels of the cylinder head of an internal combustion engine. Background technique [0002] The intake and exhaust passages of the cylinder head are the "breathing" passages of the combustion chamber of the internal combustion engine, which provide sufficient fresh air or combustible mixture for the combustion process, and discharge the exhaust gas produced by the combustion in time to ensure the smooth progress of the combustion process. The surface finish of the intake and exhaust ports directly affects the engine intake charge coefficient and combustion characteristics in the cylinder, which in turn affects the power and fuel consumption of the internal combustion engine. Improving the surface finish of the intake and exhaust passages can increase the intake air flow, reduce the intake air flow loss, and accelerate the exhaust discharge ra...
