Embodiment Construction

[0020] Take the in-line four-cylinder gasoline engine as an example

[0021] 1. The combustion chamber adopts a hemispherical structure, and each cylinder is equipped with four valves, namely: intake valve, air intake valve, exhaust valve, and exhaust air valve. Three passages are arranged for each cylinder, the intake passage and the intake air passage are arranged on the same side of the cylinder head; the exhaust air passage and the exhaust passage are shared and arranged on the other side of the cylinder head.

[0022] 2. The four valves are respectively driven by two camshafts arranged above the cylinder head. One camshaft drives the intake and intake valves, and the other camshaft drives the exhaust and exhaust valves. The gear ratio of the crankshaft timing gear to the two camshaft timing gears is 1:3. Driven by a timing gear belt.

[0023] 3. Set the phase angle and outline shape of each cam to adapt to the working process of the six-stroke engine.

[0024] 4. Set ...

Abstract

The reciprocating piston fix-stroke engine is a power device used in atomobile, locomotive, ship and engineering machine, and is a new intenral combustion engine, and is expressino of working processof existent four-stroke engine, and is characterized by that after exhaust stroke and before induction stroke two strokes of air admisssino and air discharge and air inlet channel and exhaust line are added so as to possess the actions of cleaning residual waste gas and reducing combustion chamber temperature and can obtain more completely combustion.

Description

Technical field [0001] It belongs to the technical field of internal combustion engines. Power devices used in automobiles, trains, ships, construction machinery, etc. Background technique [0002] In the existing technical field of internal combustion engines, engines can be divided into two types: rotary piston type and reciprocating piston type. [0003] Reciprocating piston engines are classified according to the number of strokes the piston needs to go through to complete a working cycle, and can be divided into two-stroke engines and four-stroke engines. [0004] The application technology of two-stroke engine and four-stroke engine has reached a relatively perfect level at present. However, due to defects in the working process determined by their inherent structure, their performance in terms of complete combustion and thermal power conversion efficiency is relatively low. [0005] In general, two-stroke engines are less economical than four-stroke engines. Only ...
