Intelligent automobile engine cooling system

Abstract

The invention relates to an intelligent automobile engine cooling system. A cooling control device compares control instructions provided by a CPU (central processing unit) by collecting and processing signals to regulate a variable water pump and a speed-governing fan according to variable indexes such as water temperature of a water circulation system inside an automobile internal-combustion engine, rotation speed of the internal-combustion engine, torque and the like; an electronic control device taking a single chip microcomputer as a core conducts the determination on work conditions according to information fed back by a sensor, and automatically regulates and controls the temperature and the flow of a coolant through the variable water pump and the speed-governing fan so as to ensure that the engine works in an optimal temperature state; and special-purpose software that is developed by a digital simulation technique and experiments can monitor operation conditions of the internal-combustion engine at the right time, and analyze, compare, compute and control water amount and air amount. The intelligent automobile engine cooling system has the advantages of reducing the fuel consumption, improving the economy of the engine, lowering abrasion and prolonging the service life.

Description

【Technical field】 [0001] The invention relates to the technical fields of electromechanical integration and electronic control, in particular to an intelligent automobile engine cooling system, which has the characteristics of reducing fuel consumption, improving engine economy, reducing wear and prolonging service life. 【Background technique】 [0002] According to CCID statistics, the national automobile production and sales volume exceeded 7.2 million in 2006, ranking among the top three in the world in one fell swoop. In 2007, China's total automobile output reached nearly 8.4 million units, and compared with 2006, the output growth rate was as high as 17%. In terms of absolute quantity, compared with 2006 and 2007, the automobile output increased by more than 1.2 million, which is quite astonishing. Compared with developed countries, China's auto industry is in its infancy. Compared with foreign car ownership, China still has a certain room for development. In 2006, th...
