Variable displacement, constant (air density) compression ratio, constant air/fuel ratio and non air throttle reciprocating engine

Abstract

The engine in this invention has five strokes of sucking, exhaling, pressing, bursting and eliminating. The sucking and exhaling divide the sucking stroke of the existing engine. The engine power is adjusted by the long-short exhaling stroke which is resolved by the coupled and combined camshaft mechanism. The engine saves the suction stroke consuming and reduces the emission without installing the air throttle. The ratio of the upper center capacity and the inflatable amount of the cylinder is kept as a constant by moving the upper and lower cylinders and the camshaft mechanism synchronously. The relative position between the upper and lower cylinders / the camshaft mechanism and the axle core under different work conditions can be detected by the sensor. The detecting value is used to calibrate the fuel supplies. The relationship between the cylinder inflatable amount and the cam mandrel 36 moving amount appears nonlinear by adjusting the shape the cam mandrel driving groove 43. It selectively optimizes the quasi-sidereal compression ratio and air-fuel ratio under different work conditions, which is more energy-saving and environmental protection than the traditional engines.

Description

[0001] TECHNICAL FIELD: This invention relates to reciprocating engines. Background technique [0002] The four-stroke throttle-controlled reciprocating engine has been in operation for hundreds of years and is one of the cornerstones of modern civilization. The research and improvement work on it has never stopped, and a large number of new technologies are used in it, and modern engines have been perfected day by day. But the so-called perfection is based on the inherent working mode. Its original and existing working mode is as follows: the four-stroke operation mode marked by suction pressure explosion, the throttle valve controls the cylinder air intake to adjust the engine operating conditions, and there is a fixed cylinder top dead center volume , the intake valve closes at a fixed angle. This kind of engine has disadvantages. The throttle control means that the suction stroke is carried out under negative pressure conditions. The suction stroke of most engines is car...
