Adjustable cooling system of engine

Abstract

The invention relates to the field of engines, in particular to an adjustable cooling system of an engine. The system comprises a cooling main circulating pipeline. The cooling main circulating pipeline comprises a main path thermostat, an engine radiator, a main path water pump, a machine oil cooler, an engine cylinder body and a cylinder cover, which are communicated in sequence; a cooling circulating branch is arranged on the main circulating pipeline; one end of the cooling circulating branch is connected with the main path thermostat, and the other end of the cooling circulating branch is connected with one end of a water outlet of the engine radiator; and the main path thermostat can distribute the flows of cooling water in the cooling main circulating pipeline and the cooling circulating branch in real time according to the temperature of the cooling water. The adjustable cooling system can reasonably distribute the cooling water to precisely perform the real-time heat management for a whole vehicle, and can realize quick vehicle heating in a cold state of the engine when the engine reaches the normal working temperature as quickly as possible, so that the mechanical efficiency of the engine is improved, and the purposes of energy conservation and emission reduction are achieved.

Description

Technical field [0001] The invention relates to the field of engines, in particular to an adjustable cooling system of an engine. Background technique [0002] The function of the automobile cooling system is to dissipate part of the heat absorbed by the heated parts in time to ensure that the engine works at the most suitable temperature. The cooling system of the engine is divided into air cooling and water cooling. The cooling system with air as the cooling medium is called air-cooling system; the cooling system with cooling liquid as the cooling medium is called water cooling system. The role of the automobile engine cooling system is to ensure that the engine works at the most suitable temperature under all working conditions. The matching of the cooling system will directly affect the service life and fuel economy of the engine, so in the design and calculation of the cooling system In the cooling system, the selection of the radiator and the matching of the fan play a vi...

Problems solved by technology

[0009] However, in the existing engine cooling system, when the engine is running, the cooling water pump drives the cooling water to pass through the engine cylinder block, cylinder head, oil cooler and warm air radiator, etc. at the engine cold start stage, the water temperature of the engine cylinder block water jacket rises. Slow, the matching gap between the piston and the cylinder liner is small, and the frictional resistance is large, resulting in large friction work during the warm-up period, increasing fuel consumption and serious pollution
