Problems solved by technology

[0002] Due to the small size and high heat load of ordinary air-cooled engines, the control and cooling of the engine oil temperature is the key to the reliability of the entire engine. The usual method is to use the heat sink of the engine itself and the heat transfer of the body to conduct heat exchange to control the oil temperature. However, when the engine needs to be strengthened, the oil temperature rises sharply and the reliability decreases

Embodiment Construction

[0013] A new type of oil cooling system with an external condenser at the air inlet of an air-cooled engine, comprising an oil inlet pipe 4 and an oil outlet pipe 3; one end of the oil inlet pipe is connected to the oil outlet of the body chamber cover 6, and the other end of the oil inlet pipe Connected with the condenser; one end of the oil outlet pipe is connected with the oil inlet of the body cover, and the other end of the oil outlet pipe is connected with the condenser 2; the condenser is fixed on the air inlet of the engine air guide cover 1 by the fixing bolt 5 . There are cooling fins on the main oil passage of the condenser. The condenser is in the form of a serpentine tube or other suitable form.

[0014] When the engine is working, the internal engine oil enters the condenser 2 through the oil outlet of the chamber cover 6 and enters the condenser 2 through the oil inlet pipe 4 under the pressure of the engine oil pump. Cooling and heat exchanging are carried ou...

Abstract

The invention discloses a novel engine oil cooling system externally equipped with a condenser at an air inlet of an air-cooled engine. The novel engine oil cooling system comprises an engine oil inlet pipe and an engine oil outlet pipe, wherein one end of the engine oil inlet pipe is connected with an oil outlet of an engine body chamber cover, the other end of the engine oil inlet pipe is connected with the condenser; one end of the engine oil outlet pipe is connected with an oil inlet of the engine body chamber cover, and the other end of the engine oil outlet pipe is connected with the condenser; and the condenser is installed on an air inlet of an engine air guide cover. The novel engine oil cooling system has reasonable structure, and enjoys extremely excellent cooling effect by sucking engine oil from the inside of an engine and enabling an engine oil cooler to have the maximum cooling area through large supply air rate of the air inlet of the air guide cover.

Description

Technical field: [0001] The invention relates to an oil cooling system of an air-cooled engine. Background technique: [0002] Due to the small size and high heat load of ordinary air-cooled engines, the control and cooling of the engine oil temperature are the key to the reliability of the entire engine. The usual method is to use the cooling fins of the engine itself and the heat transfer of the body for heat exchange to control the oil temperature. However, when the engine needs to be strengthened, the oil temperature rises sharply and the reliability decreases. Invention content: [0003] The purpose of the present invention is to provide a novel engine oil cooling system with reasonable structure and good cooling performance, which has an external condenser at the air inlet of an air-cooled engine. [0004] Technical solution of the present invention is: [0005] A new type of oil cooling system with an external condenser at the air inlet of an air-cooled engine, wh...
