Engine and cooling system for engine

Abstract

The invention provides a cooling system for an engine. The cooling system comprises a front cylinder cover, a cylinder body and a rear cylinder cover, wherein the front cylinder cover and the rear cylinder cover are arranged on two side faces of the cylinder body; the front cylinder cover is provided with a bent channel, an outlet and an inlet; two ends of the channel are connected with the inletand the outlet; the width of the position of the channel connected with the outlet is greater than that of the position of the channel connected with the inlet; the cylinder body is provided with a first flowing port, a second flowing port and a bent through groove; the rear cylinder cover is provided with a blind hole, a collecting tank and a bent flow channel; the width of the position of the flow channel connected with the blind hole is greater than that of the position of the flow channel connected with the collecting tank; and cooling fluid in the engine passes through the collecting tank and flows back to a cooling fluid supply source to fully cool the front cylinder cover, the cylinder body and the rear cylinder cover, and the cooling efficiency is improved. Moreover, by the bent arc design and dimension change design of the channel, the through groove and the flow channel, the flow rate of the cooling fluid is reduced, the retention time of the cooling fluid in the front cylinder cover, the cylinder body and the rear cylinder cover is prolonged, and the cooling effect is enhanced.

Description

technical field [0001] The present invention relates to the field of cooling systems, in particular, to an engine cooling system. Furthermore, the invention also relates to an engine having the above-mentioned cooling system. Background technique [0002] When the rotary engine is working, the heating conditions of various parts of the body are different. The temperature in the intake and compression sections is relatively low, which becomes the cold arc zone; while the temperature in the combustion expansion and exhaust section is relatively high, called the hot arc zone. The disparity in temperature between these two sections seriously affects the reliability and life of the engine. [0003] Now the water-cooled cooling method is commonly used to cool the hot arc area of ​​the engine. However, the existing cooling water circulation method and water channel structure are simple, unable to effectively cool the hot arc area of ​​the rotor engine body, and the cooling effici...
