Problems solved by technology

After the cylinder gasket is compressed, it forms a certain volume in the combustion chamber. By reducing the thickness of the cylinder gasket or replacing it with a thinner steel cylinder gasket, the volume of the combustion chamber can be reduced and the compression ratio can be increased accordingly. However, the compression ratio Improvement is also limited
However, increasing the radius of gyration of the crankshaft may involve the rearrangement of many components, which is troublesome

Embodiment Construction

[0026] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0027] figure 1 Schematic diagram of the original structure of the engine. Such as figure 1 As shown, the engine includes a cylinder liner 5, a piston 4, a cylinder head 2, a valve 1, a cylinder gasket 3, a connecting rod 6 and a crankshaft 7. The piston 4 is located in the cylinder liner 5 and can reciprocate. One end of the connecting rod 6 is connected with the piston 4 and the other end is connected with the crankshaft 7 . The piston 4, the cylinder liner 5 and the cylinder head 2 form a closed space. When the crankshaft 6 moves to the top dead center, that is, figure 1 In the position shown, the closed space formed by the piston 4, the cylinder liner 5 and the cylinder head 2 constitutes the combustion chamber of the engine.

Abstract

The invention discloses an engine which comprises a cylinder sleeve, a cylinder cover, a piston positioned in the cylinder sleeve, a link connected with the piston and a crankshaft connected with the piston through the link. The engine is characterized in that a part for reducing the volume of a combustion chamber of the engine is further arranged in confined space formed by the cylinder sleeve, the cylinder cover and the piston. The engine has the advantages that the engine can reduce the volume of the combustion chamber of the engine under the situation of minimizing the change of the original engine, thereby improving the compression ratio of the engine.

Description

technical field [0001] The invention relates to an engine, in particular to an engine with increased compression ratio on the basis of the existing engine, and belongs to the technical field of internal combustion engines. Background technique [0002] The compression ratio ε is the ratio of the total volume of the cylinder to the volume of the combustion chamber. The compression ratio indicates the degree to which the gas in the cylinder is compressed when the piston moves from the bottom dead center to the top dead center. The larger the compression ratio, the higher the pressure and temperature of the gas in the cylinder at the end of compression. With the increase of the compression ratio ε, the intake efficiency of the combustion will be improved, the thermal efficiency will be improved, the power and torque of the engine will be increased, and the fuel consumption rate will be reduced. [0003] At present, most of the development and application of methanol engines a...
