Abstract

The invention discloses a method and a system for utilizing engine waste heat. The system comprises an engine cylinder body and a cooling water jacket outside the engine cylinder body, wherein the cooling water jacket is provided with a plurality of spray heads; each spray head is connected with a water tank through a water pump; the cooling water jacket is provided with a steam outlet; the steam outlet is connected with a steam driving device; the steam driving device is connected with an electric generator; and the electric generator is connected with a storage battery. The method and the system provided by the invention are particularly suitable for gasoline-electric hybrid automobiles. Steam kinetic energy produced by cooling an automobile engine is continuously and dynamically converted into electric energy, so that an automobile storage battery is charged continuously, the construction of a special charging station for hybrid electric vehicles can be avoided, resource investment can be saved greatly, the rapid development of the gasoline-electric hybrid automobiles is promoted and the international development trends of energy conservation and emission reduction are conformed.

Description

technical field [0001] The invention relates to engine technology, in particular to a method and system for utilizing engine waste heat. The system integrates cooling, waste heat recovery and energy saving. Suitable for gasoline engines, diesel engines, etc. Background technique [0002] The function of the engine cooling system is to keep the engine in the proper temperature range under all operating conditions. During the working process of the engine, the combustion temperature in the combustion chamber can be as high as 1973~2773K (1700~2500℃). If the cooling measures are used, the excessively high temperature will significantly reduce the strength of the metal material, the moving parts may destroy the normal fit clearance due to thermal expansion, and the lubricating oil will also deteriorate due to high temperature burnout or decrease in viscosity, so that the engine parts cannot be maintained. The normal oil film can cause parts to seize or increase wear. Therefor...
