Embodiment Construction

[0052] 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.

[0053] 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 provides an engine with a variable compression ratio and a variable ignition position. According to the engine, the problems that the compression ratio is unified and ignition positionsof different engine loads are not variable in the prior art are solved. According to the technical scheme, the engine with the variable compression ratio and the variable ignition position comprises avariable compression ratio mechanism capable of changing the mechanical compression ratio and a spark plug synchronously acting with a telescopic mechanism; the compression ratios and the oil injection positions during the low-load operation of the engine are completely different from those during the medium-load and high-load operations of the engine so as to realize that the ignition positionschange along with the different compression ratio states so that the different compression ratios and the different oil ignition positions of different engine loads and different engine rotating speeds can be met, and therefore the rate of work and the power of the engine are improved through the improvement on the combustion efficiency of fuel.

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...
