Embodiment Construction

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0052] An engine with variable compression ratio and ignition position, which includes a variable compression ratio mechanism that can change the mechanical compression ratio, and a spark plug that works synchronously with the expansion mechanism, and makes the compression ratio when the engine is running at low load. The compression ratio and ignition position are completely different when the engine is running under medium load and high load, and different compres...

Abstract

The invention proposes a method for controlling the position of the spark plug in the engine, which solves the problem in the prior art that the unified ignition position of different engine loads is invariable. The technical solution of the present invention is achieved as follows: a method for controlling the position of a spark plug in an engine, comprising: adjusting the oil supplied to the hydraulic chamber based on the different rotational speeds of the engine, adjusting the oil supplied to the hydraulic chamber to increase the oil capacity will Actuating the variable compression piston to extend or adjusting the supply to the hydraulic chamber to reduce the oil capacity will cause the variable compression piston to retract, and the extension or retraction of the variable compression piston will achieve a change in the ignition position of the engine, thereby improving fuel consumption. Improve the combustion efficiency of the engine to improve the power and power of the engine.

Description

[0001] technical field [0002] The invention relates to a gasoline engine, in particular to an engine which can change the compression ratio and ignition position according to the engine load and rotation speed. Background technique [0003] The compression ratio of the engine refers to the ratio of the stroke of the working piston in the cylinder to the combustion chamber. The higher the compression ratio, the better the combustion efficiency. However, the higher the compression ratio, the higher the knocking of the engine, and the easier it is for the cylinder and piston to knock and wear. Especially under high load conditions, the power of the engine will drop instead. [0004] As the grade of gasoline gets higher and higher, the increase of octane number is to reduce the knocking caused by the high compression ratio. However, its effect is limited. It can only be controlled at 13:1. Of course, due to the refining and manufacturing process of regional gasoline for the sa...
