Problems solved by technology

If the piston stroke is increased, the height of the cylinder will increase accordingly. If the diameter of the cylinder is not increased at the same time to widen the swing space of the connecting rod, the cylinder will be stuck when the connecting rod moves.
[0004] 2. The piston and piston ring are restricted by the friction loss between the side pressure and the cylinder wall

Embodiment 1

[0027] The design and determination of structure, connection mode and structural size are as described in the summary of the invention. Only the cylinder block is an in-line 4-cylinder with a cylinder diameter of 74mm, and the linear motion guide rail is a rolling linear guide rail pair in a rolling linear guide rail.

Embodiment 2

[0029] The design method of structure, connection method and structural size is the same as Example 1, the difference is that the cylinder block is a V-shaped 6-cylinder, the diameter of the cylinder is 74mm, the linear motion guide is a rolling spline pair in the rolling linear guide, and the length of the crankshaft arm is , The piston stroke is increased by 20% on the basis of the original engine crankshaft arm length and piston stroke.

Embodiment 3

[0031] The design and determination of the structure, connection mode, and structural size are the same as in the first embodiment, except that the linear motion guide rail is a linear guide rail in the sliding guide rail. The crankshaft arm length and piston stroke are increased by 30% on the basis of the original engine crankshaft arm length and piston stroke, and the compression ratio is adjusted. The gasoline engine compression ratio is between 6-12, and the diesel engine compression ratio is between 14-22.

Abstract

The invention relates to a linear motion guide rail engine; a piston is fixed by a linear motion guide rail device and makes reciprocating linear motion on the basis of reserving the whole structural form of the original engine, the structure of the piston is improved, the height of a cylinder is reduced, and the stroke of the piston is increased, so that the output power of the engine is improved, and the power performance, the economic performance and the emission performance of the engine can be improved; and therefore, the linear motion guide rail engine which is low in consumption and high in power can be provided for the technical field of the engine.

Description

technical field [0001] The invention relates to a reciprocating piston engine, especially a linear motion guide rail engine which applies a linear motion guide rail to the engine, fixes the reciprocating linear motion of the piston, increases the stroke of the piston, and increases the torque to increase the power of the linear motion guide rail engine. Background technique [0002] The original gasoline and diesel engines are generally composed of a body (body group), two mechanisms (crank linkage, gas distribution mechanism), and five major systems (fuel supply system, ignition system, cooling system, lubrication system and starting system). The crank connecting rod mechanism is composed of a piston connecting rod group and a crankshaft flywheel group. It is the main mechanism for reciprocating piston engines to convert heat energy into mechanical energy. During the working process, the combustion gas pressure directly acts on the piston, pushing the piston to reciprocate ...
