Method for increasing air-fuel ratio of engine and supercharged engine

Abstract

The invention discloses a method for increasing the air-fuel ratio of an engine and the supercharged engine. The supercharged engine comprises an air cylinder, a piston, a spark plug, an air intake valve, an exhaust valve, an air intake valve cam and an exhaust valve cam, wherein the air intake valve cam and the exhaust valve cam are arranged on a cam shaft and used for controlling opening and closing of the air intake valve and the exhaust valve. A supercharged air valve is further arranged on the air cylinder and is connected with a constant-pressure air storage tank. A supercharged cam controlling the supercharged valve to open and close is additionally arranged at the corresponding position of the cam shaft. Thus, the supercharged valve is controlled to be opened through the additionally-arranged supercharged cam while the engine completes normal air intake, and therefore compressed air of the constant-pressure air storage tank enters the air cylinder of the engine through the supercharged valve, the content of air in the air cylinder is additionally increased, the air-fuel ratio of the engine is increased, the air intake of the engine is greatly increased, consumption of the oil amount is reduced, the work efficiency of the engine is improved, and the content of harmful components in exhaust waste gas is reduced.

Description

technical field [0001] The invention relates to a method for increasing the air-fuel ratio of an engine and a supercharged engine, belonging to the technical field of engines. Background technique [0002] With the continuous development of automobile technology, all countries in the world are improving automobile engines and have achieved a lot of results, but they have not made breakthrough improvements to the working methods of engines. Exhaust gas turbocharged engines are a good example. Although It has been applied to internal combustion engines at present, and has achieved good economic and environmental protection effects, but the work efficiency is not satisfactory, and the fuel saving effect is not obvious. Contents of the invention [0003] The purpose of the present invention is to provide a method for improving the air-fuel ratio of the engine and a supercharged engine with a novel structure, stability and reliability, and high working efficiency, thereby great...
