Abstract

The invention proposes a piston with variable compression ratio and 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 the following way: a piston with variable compression ratio and ignition position, characterized in that the fox surface of the variable compression piston constitutes a second combustion chamber, and the second combustion chamber is connected with the first combustion chamber of the cylinder head. A combustion chamber works together; the variable compression piston projects a support column from the inside, and at least one spark plug seat hole is designed in the support column, and the spark plug seat hole is used for installing a spark plug. The surface of the second combustion chamber of the variable compression piston and the surface of the first combustion chamber of the cylinder head are arc-shaped, spherical or conical. To meet the combustion efficiency at different engine loads and different engine speeds, so as to improve the fuel combustion efficiency and improve the power and power of the engine.

Description

Technical field [0001] The invention relates to a gasoline engine, in particular to an engine that can change the compression ratio and ignition position according to the engine load and speed. Background technique [0002] The compression ratio of an 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 engine knock, and the easier it is for cylinders and pistons to knock and wear. Especially under high load conditions, the power of the engine actually drops. [0003] As the mark of gasoline gets higher and higher, the increase in octane number is to reduce the knocking caused by the high compression ratio, but its effect is limited. Its compression ratio is the same as that of Mazda's Blue Sky technology engine. It can only be controlled at 13:1. Of course, due to the regional gasoline refinement an...
