Technical field

The present invention relates to field of dynamic engineering, restore dress more particularly, to a kind of diesel engine performance suitable for height above sea level switching It sets and its applies.

Background technique

Diesel engine is mechanical as communications and transportation important in modern society and power output, has extensively in each industrial circle General application, and China territory length and breadth of land, it is with a varied topography, it is dispersed with the highlands of many High aititudes.Therefore, either engine Tool or apparatus of transport, all may be in face of turning to the case where high altitude localities works by low altitude area.And in high altitude localities, Since air pressure reduces, atmospheric density decline causes the diesel engine remained running under original configuration performance loss occur.

Performance compensation for the diesel engine run in high altitude localities, there are many implementations.On the one hand it can improve The Design Technology for Diesels parameter such as air intake duct, port timing, combustion-chamber shape, compression ratio is carried out for High aititude running environment again Design.However such method can not solve the performance compensation that same diesel engine switches to high altitude localities operation from low altitude area Problem.On the other hand being then can be by changing diesel pressure booster pressure ratio and pressurization series, and increase actually enters cylinder Atmospheric density, the kinetic energy of kinetic energy or diesel engine itself of the pressurization motive power source of such method in exhaust gas, and exhaust gas pair Required by diesel engine condition has, engine driven supercharging then needs additionally to consume the kinetic energy of diesel engine itself, and improvement cost is higher and is difficult to Realize performance recovery without side-effects.

Therefore, developing one kind can be without side-effects to diesel engine performance itself, while having no need to change engine block The High aititude performance recovery device of parameter, has important practical significance.

Summary of the invention

It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind can improve high sea Rise sheer from level ground the inlet air conditions of area's diesel engine, is allowed to be restored to low altitude area level, is run with improving diesel engine in high altitude localities The diesel engine performance recovery device for being suitable for height above sea level switching of performance loss and its application.
