The Characteristic And Elements Of Turbocharger-www.277.cc

Automobiles The Characteristic of turbocharger Turbo charging is a technology that air-.pressor is driven by the waste gas produced from Internal .bustion Engine, being similar with the function of Super-charger, both of which can increase the air mass flow accessing into Internal .bustion Engine or boiler thus improving machinery efficiency. It is usually applied for automobile engine. Turbocharger can easily improve the horsepower output of Internal .bustion Engine, using the rate of heat and flow of waste gas discharged. Turbocharger can improve widely the power and torque of engine without increasing the engine emission, which is its great advantage. Generally, the power and torque of engine would be increased 20%-30% after installing turbocharger. The weakness of turbocharger is turbo-lag to the sudden variation of accelerator caused by inertia of impeller, making engine delay increasing or reducing output power, which may make the vehicles accelerating promptly and overtaking seems to be suspended suddenly. .pared with Aspirated Engine, the engine with turbocharger could increase the maximum power with 30%-40%, even more. Especially at the high altitude area with thin air, it would be more powerful. Besides this, it still has lower torque breaking point and wider torque than aspirated engine. These characteristics enable the automobile accelerate quickly and be with a good motive power. As a result, under the help of turbocharger, displacement automobiles could have the motive power matching the high displacement ones while reducing 10%-20% CO2 discharging, which contributes a lot to environment protection. Then, when you drive steadily, it is not likely to consume more fuel than the same displacement automobile without turbocharger. Consequently, turbocharger will be a development direction for further automobile power. The Elements of Turbocharger Turbocharger consists of pump impeller, turbine and other control .ponents. Pump impeller and turbine are connected by an axis named rotor. The waste gas exhausted by engine drives pump impeller which drives turbine spinning. The spinning turbine would pressurize the air inlet system. The operating temperature for supercharger is very high because of being installed at the exhaust side of engine. In addition to this, the rotate speed of the rotor is extremely high when it’s working, almost several hundred thousand turns per minute. Obviously, the regular mechanical needle and ball bearing can not bear such high rotation speed and temperature, thus, turbocharger generally uses the full suspension bear, lubricating with engine oil and cooling with cooling liquid. Formerly,  garrett turbocharger  was mostly used in diesel motor. However, nowadays, it is also widely applied to oil engine. About the Author: 相关的主题文章:
