A pneumatic starting system for automobile engine

Abstract

The invention relates to a pneumatic starting system of an automotive engine. The pneumatic starting system is used for reducing adverse impact on a motor and a storage batter due to frequent starting of an engine, and comprises a heat exchanger, a water sprayer, a high-pressure steam storage tank and a steam cylinder. The heat exchanger is connected in an exhaust system pipeline, the water sprayer is assembled with the heat exchanger, the high-pressure steam storage tank is communicated with the heat exchanger through a high-pressure steam storage tank air inlet and also communicated with an air inlet of the steam cylinder through a high-pressure steam storage tank air outlet, the steam cylinder is mounted in an engine body and abreast with an engine cylinder, and an exhaust port of the steam cylinder is communicated with an engine exhaust system. The pneumatic starting system has the advantages that energy of engine tail gas is utilized effectively, the problem that an engine motor driving system starts frequently is solved, and thus service lives of the motor and the storage battery are prolonged, and economic performance of a vehicle is improved.

Description

technical field [0001] The invention relates to an automobile engine starting system, in particular to an automobile engine starting system driven by generating high-pressure water vapor from the heat of engine exhaust, and belongs to the technical field of combustion engines. Background technique [0002] For traditional gasoline engines, only part of the energy generated by fuel combustion is used to do work, part is absorbed by cooling water, and the rest is taken away by high-temperature exhaust gas. If the energy of high-temperature exhaust gas can be recovered and utilized, it will not only improve the thermal efficiency of the engine, but also improve the efficiency of the engine. Achieving vehicle energy efficiency and emission reduction targets will have a positive impact. [0003] Cars often stop at red lights when driving on urban roads. Relevant studies have shown that the fuel consumption of the engine idling for ten seconds is greater than the fuel consumption ...

Problems solved by technology

However, the current engine starting system uses a single motor drive mode, which is powered by the battery. The engine drives the generator to charge the battery while the vehicle is running. Frequent starting of this system will reduce the life of the battery and the motor. The starting speed is slow and takes time. Long, and it takes a few seconds to stabilize before driving
