Rear-mounted single-cylinder water-cooled automobile engine cooling cycle system

Abstract

The invention discloses a cooling cycle system for a water-cooled automobile engine with a rear single cylinder. The system comprises a thermostat, a fan heater, a radiator and a water pump, wherein the thermostat is connected with the fan heater through an engine water outlet pipeline, the radiator and the water pump are connected through an engine water return pipeline, an h-shaped exhaust tee joint is arranged between the thermostat and the fan heater, the two ends, located on the lower portion, of the exhaust tee joint are a water inlet and a water outlet respectively, the end, on the upper portion, of the exhaust tee joint is provided with an automatic exhaust valve, a water outlet of the thermostat is connected with the water inlet of the exhaust tee joint, and the water outlet of the exhaust tee joint is connected with a water inlet of the fan heater. The cooling cycle system has the advantages that the h-shaped exhaust tee joint and the automatic exhaust valve are additionally arranged between the thermostat and the fan heater, so that gas energy accumulating in the pipelines can be released timely through the exhaust tee joint during operation of the engine and is discharged out of the cycle system through the automatic exhaust valve; a manual exhaust valve is additionally arranged at the upper end of the radiator so that little gas accumulating in the pipelines can be released conveniently and cooling liquid can be conveniently injected into an expansion tank.

Description

technical field [0001] The invention relates to the technical field of single-cylinder water-cooled engines, in particular to a rear-mounted single-cylinder water-cooled automobile engine cooling circulation system. Background technique [0002] In the existing rear single-cylinder water-cooled automobile engine cooling cycle system, the hot coolant after cooling the engine is directly connected to the heater and radiator through the thermostat, and after cooling through the radiator, it is injected by the water pump through the engine return pipe Engine, cool down the engine. The water injection port of the radiator of this system is equipped with a pressure release valve, the purpose is that when the gas accumulated at the water injection port reaches a certain pressure, the pressure release valve will automatically open to release the gas. This device is very effective for cars with a large water pump in the front of the engine, because the front of the engine can make t...

Problems solved by technology

At this time, the coolant around the engine cylinder will quickly vaporize to form a gas cavity, and because the distance between the water pump and the cylinder is relatively short, the cavity around the cylinder will quickly extend back to the water pump, causing the water pump to lose its function and causing the engine to lose its function. The temperature is too high, or even damaged
