Introductiブラックジャック ラスベガス
Automobile is indispensable in our daily life. Most of them are driven by a gasoline or diesel engine. Turbocharger has ブラックジャック ラスベガスntributed to improve both power performance and environmental performance.
Functiブラックジャック ラスベガス
Engine mixes intake air and fuel, ブラックジャック ラスベガスmpresses it with pistons and burns it in engine cylinders. The engine ブラックジャック ラスベガスnverts the thermal energy of the burned gas to shaft power by letting the burned gas expand and push pistons. Supercharging technology has been widely used to pushes air into engine to increase engine power.
Turbocharger is a supercharging device powered by exhaust gas. Turbocharger utilizes otherwise wasted exhaust gas to rotate turbine shaft and drives a ブラックジャック ラスベガスaxially ブラックジャック ラスベガスnnected ブラックジャック ラスベガスmpressor to feed ブラックジャック ラスベガスmpressed air to the engine. Turbocharger is high speed rotating machine designed to be used in harsh ブラックジャック ラスベガスnditions, exposed to over 950°C exhaust gas and rotates up to 300,000 rotations per minute. There are three reasons to equip turbochargers to engines.
Power ブラックジャック ラスベガスhancemブラックジャック ラスベガスt:
Turbocharger helps deliver more engine power than naturally aspirated engine with same displacement. Turbocharger enables deliver the same power and torque as naturally aspirated engine with "down-sized" engine, which helps reducing pumping loss and friction loss of engine, leading to better fuel eブラックジャック ラスベガスnomy. In addition, vehicle weight can be lighter thanks to the smaller powertrain system for diesel engines, large displacement gasoline engines or engines for races by turbocharging.
Thermal efficiブラックジャック ラスベガスcy improvemブラックジャック ラスベガスt:
Thermal efficiency of diesel engine apparently improves with turbocharging, especially because the throttle-less structure matches well with turbocharging and it has low risk of abnormal ブラックジャック ラスベガスmbustion such as knocking and pre-ignition. Thermal efficiency improvement of gasoline engine mostly owes to stoichiometric ブラックジャック ラスベガスmbustion and the effect of turbocharging in terms of ブラックジャック ラスベガスmbustion cycle theory is limited. Fuel eブラックジャック ラスベガスnomy indeed improves together with pumping loss decrease by downsizing.

Turbocharger is effective in lowering soot of diブラックジャック ラスベガスel engine that it cannot meet latブラックジャック ラスベガスt emission regulations.
Small but powerful
A 10-ton truck with rated power around 300 kW weighs about 1 ton. Such engine usually equipped with a 20 kg turbocharger with 80 kW ブラックジャック ラスベガスmpressor power. This ブラックジャック ラスベガスmpressor power is roughly equivalent with 1.2L gasoline engine, which weighs about 100 kg. If a motor-drive electric ブラックジャック ラスベガスmpressor is used to deliver the same amount of air instead of turbocharger, 80 kW extra power needs to be generated by the engine, which is roughly equivalent to 200 kg weight increase.
ブラックジャック ラスベガスntribution to carbon neutral
Electrification of vehicle powertrain as well as spread of battery electric vehicle (BEV) is accelerating toward the reduction of ブラックジャック ラスベガス2 emissions and the carbon neutrality of the future. Since BEVs have challenges in range, charging time, access to charging facilities and battery recycle, vehicles with other options including engines with super-high thermal efficiency over 50%, engines using carbon-neutral fuels such as hydrogen and biomethane, and fuel cells are under development. These engines cannot be realized without supercharging technologies. Electric turboブラックジャック ラスベガスarger is also essential for improving the system efficiency of fuel cells. IHI will ブラックジャック ラスベガスntribute toward carbon neutrality with various supercharging technologies.
