Continuous adjustable piston height type self-locking energy-saving engine

Abstract

The invention discloses a continuous adjustable piston height type self-locking energy-saving engine. The engine comprises an engine system and a piston adjusting system, wherein the engine system comprises a cylinder cover, an electric oil injector, a cylinder body, a main piston, a connecting rod, a crankshaft and an engine oil pump, wherein the piston adjusting system comprises a secondary piston, a self-locking solenoid valve, a returning solenoid valve, a returning spring, a controller, a pressure sensor and a temperature sensor; the secondary piston, the returning solenoid valve and thereturning spring are sleeved with the main piston; the self-locking solenoid valve is connected to the cylindrical sidewall between the main piston and the secondary piston; and an oil inlet and an oil outlet are formed in the lower part of the main piston. The engine is simple in structure; the adjusting method is simple, easy and reliable; the requirements on the discharge, compressing ratio, inner pressure of a cylinder and temperature in the cylinder of the engine under different rotating speed and different load can be met in real time; the applicable scope is wide; and the good economicbenefits and the emission reduction effect are achieved after popularization.

Description

technical field [0001] The invention relates to an energy-saving engine, in particular to an energy-saving engine with continuously variable and self-locking piston height. Background technique [0002] The engine piston and connecting rod group includes piston, piston pin, connecting rod, etc. The piston is connected to the small end of the connecting rod through the piston pin, and the large end of the connecting rod is connected to the crankshaft through the crank pin. The linear reciprocating motion of the piston is converted into the rotation of the crankshaft through the connecting rod. sports. Once the traditional piston connecting rod group is processed and assembled, its structural size is invariable under different engine operating conditions. With this structure of engine, the displacement and compression ratio of each cycle engine are operated according to the design value of the engine, and it is impossible to adaptively adjust the displacement, compression rat...

AI Technical Summary

Problems solved by technology

This invention patent has changed the connection mode of the traditional piston connecting rod group and crank connecting rod mechanism. Compared with the traditional structure, the structure of the invention patent is complicated. In addition to the traditional piston connecting rod group and crank connecting rod mechanism, an additional oil storage is added. Chamber, variable piston, connecting rod, eccentric cam, crank pin, oil pump, control valve and other components require an additional drive oil pump device and hydraulic oil, etc. The mechanism is complicated and the cost is high, so it is not suitable for mass transformation of existing engines
