Embodiment Construction

[0054] 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.

[0055] 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 an engine with variable compression ratio and variable ignition position, which solves the problem of uniform compression ratio and invariable ignition position of different engine loads in the prior art. The technical solution of the present invention is achieved in this way: a variable compression ratio and ignition position engine, which includes a variable compression ratio mechanism that can change the mechanical compression ratio, and a spark plug that works synchronously with the telescopic mechanism, and makes the engine The compression ratio at low load operation is completely different from the compression ratio and ignition position at medium load and high load operation of the engine. The ignition position also changes when different compression ratios are achieved to meet different compression ratios and different ignition positions at different engine loads and different engine speeds, thereby improving fuel combustion efficiency and increasing engine power and power.

Description

technical field [0001] 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 [0002] 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. [0003] 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 same engi...
