Abstract

This invention relates to a variable stroke engine, in addition to its working method, which belongs to vehicle engine technique field. The engine comprises six cylinders, EGR, exhaust-gas turbocharger system, four strokes discharge distributing valve, exhaust duct, bent axle piston and electrical controlling unit. when working, it needs to decide whether the two stroke cylinders join to work with the jar cutting technique according to different power, making the engine switch in different working condition; the six cylinders will bedding-in work through each inlet distribution valve to increase pressure and power output. Said invention can be used in transporting vehicle such as tank armored vehicle, machineshop truck needs to provide large power output and so on.

Description

technical field

[0001] The invention relates to a variable-stroke engine and a working method thereof, belonging to the technical field of vehicle engines in the direction of mechanical manufacturing in power engineering and engineering thermophysics. Background technique

[0002] Common internal combustion engines can be divided into two-stroke internal combustion engines and four-stroke internal combustion engines according to different cycle modes. The two-stroke internal combustion engine piston completes one cycle up and down each time, the upward behavior is the intake compression stroke, and the downward behavior is the power exhaust stroke. The piston of a four-stroke internal combustion engine completes a cycle twice up and down. First, the piston goes down for the intake stroke, then the piston goes up for the compression stroke, then the piston goes down again to complete the power stroke, and finally the piston goes up for the exhaust stroke. Both cycle forms of...
