Horizontal diesel engine cooling water-inlet chamber

Abstract

The present invention relates to a horizontal diesel engine cooling inlet cavity, which belongs to diesel field. Characterized in that lower side body of inside horizontal diesel engine is equipped with special cooling inlet cavity, special connecting passage is placed between cooling inlet cavity and air cylinder chilled water apartment, right side body (flywheel end-face) or left side (gear face) has waterproof pump mounting face and water inlet of cooling inlet cavity, left side or right side of body has sand hole of cooling inlet cavity. Because it designs forced cooling inlet cavity between body bottom oil pan mounting face and air cylinder cooling water jacket, the present invention make connecting passage distance short, and is propitious to chilled water circulate, which has the advantage of compact conformation, good cooling effect, no-vapor loc, and is a new type structural horizontal type single-double cylinders diesel engine cooling inlet cavity.

Description

Horizontal diesel engine cooling structure technical field The invention relates to a cooling water inlet chamber of a horizontal diesel engine body. It belongs to the field of diesel engine cooling system. Background technique Diesel engine body cooling water inlet chamber is an important part of diesel engine cooling system. Its structural design requirements must ensure that the structural design and layout of the body cooling water chamber is simple and convenient; The vapor resistance phenomenon in water and the rationality of its structural design directly affect the power, economy, reliability and emission performance indicators of the diesel engine. Chinese patent CN200720104721.2 proposes a forced cooling structure for a single- and double-cylinder horizontal diesel engine. It uses a forced cooling structure to greatly improve the cooling effect of single-cylinder and double-cylinder horizontal diesel engines. The upper front end of the cylinder horizontal diese...

Chinese patent CN200720104721.2 proposes a forced cooling structure for a single- and double-cylinder horizontal diesel engine. It adopts a forced cooling structure, which greatly improves and enhances the cooling effect of single-cylinder and double-cylinder horizontal diesel engines, but the cooling water inlet chamber is set in the single- and double-cylinder The upper part of the front end of the cylinder horizontal diesel engine body, that is, on the cooling water channel, sometimes steam resistance occurs during use, which reduces the cooling effect
