Problems solved by technology

[0002] At present, the exhaust volume of the traditional internal combustion engine is fixed, and the speed and power are controlled by the throttle valve. The biggest disadvantage of the internal combustion engine controlled by the throttle valve is that the oil-air mixing ratio cannot reach the best state, resulting in rich gas and poor fuel or rich gas. Oil-poor gas, resulting in a large loss of fuel or air pollution due to insufficient combustion

Abstract

The present invention discloses a displacement-adjustable internal combustion engine. A rotatable upper camshaft is added on the original internal combustion engine; a sliding key can be controlled by an operating lever to slide to the left and the right in a runner, so that the upper camshaft can be rotated at different angles in the sleeve of a driven gear; and a steadier and a valve tappet are utilized to control the closing time of an intake valve assembly, so that the closing time of an intake valve can be controlled and therefore displacement can be adjusted. A piston shaft is flexibly connected with a crankshaft, the compression ratio of a combustion chamber can be adjusted by adjusting spring pressure or liquid pressure, so that the fuel-air mixture ratio can reach the optimal state, and thereby, not only can fuel be saved, but also environment pollution can be reduced.

Description

technical field [0001] The invention relates to an internal combustion engine, in particular to an internal combustion engine with adjustable displacement of overhead double camshafts and constant compression ratio. Background technique [0002] At present, the exhaust volume of the traditional internal combustion engine is fixed, and the speed and power are controlled by the throttle valve. The biggest disadvantage of the internal combustion engine controlled by the throttle valve is that the oil-gas mixing ratio cannot reach the best state, resulting in rich gas, poor fuel or rich gas. Oil-poor gas, resulting in a large loss of fuel or atmospheric pollution due to insufficient combustion. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the above-mentioned technologies, and provide an adjustable internal combustion engine with compact structure and reasonable design, which can change the drawbacks of traditional ...
