Engine and vehicle with such engine

Abstract

The invention discloses an engine and a vehicle with the same. The engine comprises a crank connection rod mechanism, sparking plugs, diesel sprayers, gasoline sprayers and a gas distribution mechanism. The crank connection rod mechanism comprises an engine block set, a piston connection rod set and a crankshaft flywheel set. At least one cylinder is arranged in a cylinder body of the engine block set. Gas inlet ways corresponding to the cylinders respectively and exhaust ways corresponding to the cylinders respectively are formed in a cylinder cover of the engine block set. At least one sparking plug is correspondingly arranged on each cylinder. At least one diesel sprayer is correspondingly arranged on each cylinder. The gas distribution mechanism comprises inlet valves and exhaust valves. Each inlet valve and the corresponding exhaust valve are used for opening or closing a corresponding combustion chamber. The swirl rate of the combustion chambers ranges from 1 to 6. The compression ration of the combustion chambers ranges from 13 to 17. According to the engine, by reasonably controlling the compression ratio and the swirl rate, a good combustion effect can be achieved, and the combustion efficiency, the power output performance and the fuel economy of the engine can be easily improved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an engine and a vehicle with the 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 tempera...

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
