Engine

Abstract

The invention discloses an engine and belongs to the technical field of engines. The engine comprises a cylinder body (1), a crankshaft and pistons arranged in the cylinder body (1), the pistons are connected to the crankshaft through connecting rods, the engine is characterized in that the number of the sleeved pistons is at least two, every two adjacent pistons are connected in a sliding mode, aheight difference exists between the tops of the combustion chambers corresponding to every two adjacent pistons, the top of each combustion chamber serves as the wall of the combustion chamber on the adjacent outer side of the combustion chamber, and an air inlet (8), an air outlet (9) and an oil inlet which are communicated with the combustion chambers are formed in the cylinder body (1). According to the engine, the structure of the piston of a traditional engine is changed, the piston is arranged to be connected in a sleeved mode, when the multi-cylinder engine is arranged, the size of the engine is greatly reduced, the occupied space of the engine is small, and enough space is reserved for installation of other components of an automobile engine bin.

Description

technical field [0001] An engine belongs to the technical field of engines. Background technique [0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. At present, the engines used in automobiles are usually internal combustion engines. Since many indicators of the engine are related to the displacement, generally speaking, the larger the displacement, the greater the output power of the engine. In order to increase the displacement of the engine, the engine is usually Set to multi-cylinder. [0003] At present, the arrangement forms of the cylinders of the multi-cylinder engine mainly include in-line, V-shaped arrangement, W-shaped arrangement and horizontally opposed arrangement, etc., which leads to the bulky size of the engine and takes up a lot of space, whic...
