Diesel Turbocharger Pursues Energy With Reduced Emission For The Automobile
Until 1999, Volkswagen Company created 3L Lupo automobile diesel turbocharger motor
. This motor power efficiency produced the whole world astonished. The conception car adopting this type motor recognized oil saving globe file of 0.99L for each hundred kms. Until then, people started to realize that diesel motor was the mainstream technologies in future which was to make a splendid new era.Diesel motor is more green and environmental protectiveAccording to some senior car engineers introduction, higher energy efficiency and superb economic efficiency would be the biggest good points of diesel engine, though every operating recycle of diesel engine is identical with gasoline engine that needs air inflow, compression, power working and emission four programs. But because the gas diesel motor makes use of is diesel, and its viscosity is harder than gasoline, it doesn't easily vapor. Also for the reason that diesel self-ignite temperature is lower than gasoline, the developing and igniting way of flammable mixture gasoline are all various with gasoline engine.As being understood, combination gas in diesel engine cylinder isn't ignited but compressed to burn. Throughout diesel motor works, what enters it really is gas and gas in cylinder is compressed to finish with the temperature between 5000 and 7000 centigrade, stress at 40 to 50 units. When plunger is near to the up finish, high-pressure pump on motor sprays diesel to cylinder on high stress. Diesel develops into small oil drop. Combining with high stress and higher temperature gasoline, diesel combination gasoline self-burn, expand fiercely and bring explosion power, subsequently prompt plunger to complete downward power work. At this time, temperature might attain to 1900 to 2000 centigrade, stress to sixty to hundred units and energy price is much higher. So, diesel motor is commonly applied in big diesel vehicle.The benefit of diesel engine in energy saving and carbon dioxide emission isn't replaceable by all heat motor which includes gasoline motor by turbocharger manufacturer. Presently, superior small size high pace gasoline engine emission has reached Europe III criteria. It really is marked with green engine'. Many newly researched European America cars all adopt diesel engine as the dynamic equipment. Technology improvement prompts diesel engine popularityDocument reveal, diesel motor is 30 percent higher in warmth efficiency compared with gasoline engine. Subsequently from the aspect of energy saving and fuel reduction, popularity of diesel motor automobile usage is of more significance. Diesel motor has the characteristics of higher power effectiveness, longer lifetime and better dynamic personality compared with gasoline engine. The green house effect caused by its emission is 45 percent lower than gasoline. Carbon monoxide and hydrocarbon emission is also decrease. Only Netrogen oxide emission is a bit higher than gasoline motor in the whole wagon usage lifetime.Recently, diesel engine adopts turbocharger, inner cooler, direct injection, exhaust catalytic conversion and DPF technologies and diesel engine vehicle emission has attained Europe III and Europe IV emission requirements. It can be predicted that with the growth of technology, little car equipped with diesel motor will become a trend of automobile development in long term.Taxi favor energy saving diesel engineAs taxi, changing the gas kind is an efficient way to reduce operation cost. Now, the proportion of diesel automobile in taxi market is frequently rising. Among newly purchased taxis, most drivers wish to choose diesel automobile as the replacing automobile type and few of them select gasoline as the fuel to operate. Diesel engine rotates a lot decrease and cylinder burning temperature is comparatively lower, so the failure price is decrease than gasoline motor without higher pressure igniting system. By way of the reduced rotation pace, component abrasion is comparatively slight and its usage lifetime is longer. Since diesel seldom emerge circumstance of burning and explosion, gas leakage consequence of it is much slighter than gasoline car.Nowadays, how to fully develop gas effectiveness and save resource has grown to become a problem we common face. Some professional individuals reveal that diesel automobile technology daily tends to be mature nowadays, it truly is sure to bring great social significance and financial meaning.by: sdaxc
