Internal combustion engine block and internal combustion engine applying block

Abstract

The invention discloses an internal combustion engine block. The internal combustion engine block comprises a body, a cylinder, runway seats, a guide slide way and main bearing seats, wherein the body is a hollow cavity; two runway seats are arranged on the left side and the right side of the body and are coincident with each other along a central plane in the width direction; the two main bearing seats are arranged on the front side and the rear side of the body; central axes of cavities of the two main bearing seats are collinear; the cylinder is arranged above the body; the guide slide way is arranged below the body; the central axes of the cavity of the guide slide way and the cavity of the cylinder are coincident with each other; the central line of the cavity of a bearing hole is vertically crossed with both the central line of the cylinder and the central plane of two runways in the width direction; the central line of the cylinder is parallel to the central planes of the two runways in the width direction and is a predetermined distance away from the central planes; and a netlike grid structure is also arranged on the outer wall of the block body at the peripheries of the two runway seats. The block can be applied to an internal combustion engine of a crank round slide block mechanism and has lower vibration and noise. In addition, the invention provides the internal combustion engine applying the block.

Description

technical field [0001] The invention relates to a single-cylinder internal combustion engine, in particular to a single-cylinder internal combustion engine body adopting a crank circular slider mechanism. The invention also relates to an internal combustion engine using the body. Background technique [0002] Single-cylinder internal combustion engines, especially single-cylinder diesel engines, have a huge demand and inventory in my country. The annual output of single-cylinder agricultural diesel engines is more than millions. However, in the traditional single-cylinder internal combustion engine, the motion conversion mechanism adopts a crank connecting rod mechanism. The reciprocating motion of the piston is converted into the rotational motion of the crankshaft through the crank-link mechanism, and then the crankshaft outputs torque to drive the driven equipment. Due to the swing of the connecting rod, the single-cylinder internal combustion engine of the traditional...

Problems solved by technology

However, due to the structural difference between the crank-slider mechanism and the traditional crank-connecting-rod mechanism, the traditional single-cylinder internal combustion engine body applied to the crank-connecting-rod mechanism cannot be directly applied to the crank-sliding block mechanism, and it is necessary to design a new The body of a single-cylinder internal combustion engine with a circular slider mechanism, especially the body of a vertical single-cylinder internal combustion engine that conforms to the current industrial policy
