Abstract

The invention discloses an engine. The engine comprises a crank link mechanism, spark plugs, diesel injectors, a gasoline injector and a distribution mechanism, wherein the crank link mechanism comprises a machine body set; cylinders are arranged in a cylinder body of the machine body set; intake and exhaust ways corresponding to all the cylinders are formed in a cylinder cover of the machine body set; an upward concave structure is formed on the bottom surface part, corresponding to the cylinders, of the cylinder cover; each cylinder is correspondingly provided with one spark plug; each cylinder is correspondingly provided with one diesel injector; the distribution mechanism comprises intake valves and exhaust valves corresponding to all the cylinders; included angles between the center lines of the intake valves and vertical planes passing through the longitudinal center line of the engine are within 0-5 degrees; included angles between the center lines of the exhaust valves and the vertical planes are 0-5 degrees; and a compression ratio is 13-17. The engine can obtain a better combustion effect through reasonably controlling the compression ratio and the valve setting angles, and facilitates to improve the combustion efficiency, the power output performance and the fuel economy.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an engine. Background technique [0002] The block group of the engine includes the cylinder head, cylinder head gasket, cylinder block and oil pan. A plurality of cylinders are formed in the cylinder body, and the piston can perform reciprocating linear motion in the cylinders. When the engine works in a cycle, especially for the compression stroke and the power stroke, the piston will exert a large force on the cylinder wall, and the cylinder wall is prone to deformation under the action of this force for a long time, thereby reducing the fuel economy, power and performance of the engine. Emission performance, resulting in poor performance of the engine. [0003] In addition, traditional gasoline engines have poor thermal efficiency and are not as efficient as diesel engines. Diesel engines have higher emissions, especially when starting at low temperature, harmful gas emissions ar...

Problems solved by technology

When the engine works in a cycle, especially for the compression stroke and the power stroke, the piston will exert a large force on the cylinder wall, and the cylinder wall is prone to deformation under the action of this force for a long time, thereby reducing the fuel economy, power and performance of the engine. Emission performance, resulting in poor performance of the engine

[0003] In addition, traditional gasoline engines have poor thermal efficiency, which is not as high as diesel engines, and diesel engines have higher emissions, especially when starting at low temperatures, harmful gas emissions are doubled, and there is a problem of difficulty in starting at low temperatures
