What is Mitsubishi GDI?
In practice, the engine is throttled slightly, and the air-fuel ratio is controlled between 30 and 40 to introduce extensive exhaust gas recirculation. For medium loads, the ratio is controlled between 20 and 25 to obtain optimal fuel economy.
Which Mitsubishi cars have GDI engines?
The company has to date developed three GDI engines: the 1.8-liter unit that powers the GALANT / LEGNUM and CARISMA; the 3.0-liter unit that powers the DIAMANTE; and the 3.5-liter unit that powers the PAJERO and CHALLENGER.
Is GDI good engine?
GDI engines provide many benefits that conventional fuel injection can’t. With gasoline direct injection technology, you can draw more power from smaller engines. In addition, your car gets improved fuel efficiency and reduced emissions. While great, the power of the GDI engine is a double-edged sword.
Which cars use GDI engines?
Other manufacturers offering or planning to offer GDI engines include Audi, BMW, Hyundai, Kia, Mazda, Mercedes-Benz, Nissan, Lexus, Saab, Subaru and Volkswagen. The big unknown is whether gasoline direct injection will get leapfrogged by more advanced technologies.
Does Mitsubishi use GDI?
Today, GDI engines power eleven Mitsubishi Motors models, and the company plans to power all its models using this technology by the year 2010. The company is currently developing other low-consumption technologies around the GDI engine.
Is a GDI engine diesel?
In a sense a GDI engine is like a DI diesel engine but with a suitably-positioned spark plug and a gasoline fuel, instead of the easily auto-igniting diesel fuel, in-cylinder injection system. In practice, some degree of throttle control is usually required for GDI engines, compromising the SFC improvement potential.
Is GDI a turbo?
GDI stands for Gasoline Direct Injection, and the T denotes Turbo. In terms of Proton’s engine development, this means a move away from multi-point injection (MPI) where the injectors shoot fuel into the inlet tract to the more efficient GDI, with injectors firing directly into combustion chamber.
Is the 6G74 GDI an environment friendly engine?
The new 6G74 GDI is a more environment-friendly engine, realizing a 30 percent reduction (in the 10-15 mode fuel economy test) in CO2 emissions which are considered a factor in global warming.
When did the Mitsubishi 6G74 V6 come out?
The gasoline direct injection version of the 6G74 was launched in April 1997 as the first GDI V6 engine ever produced.
How many cylinders are in a 6G74 engine?
6G74 Descriptions 6G74 24-valve 6G74 24-valve-GDI Type 60 OHV, SOHC 60 OHV, DOHC Number of cylinders 6 6 Combustion chamber Pentroof type Pentroof+curved top piston type Total displacement dm33,497 3,497 Cylinder bore mm 93.0 93.0 Piston stroke mm 85.8 85.8 Compression ratio 9.0 10.4 Valve timing Intake valve Opens (BTDC) 13 *1, 5 *28 *3, 12 *4
What kind of engine does a Mitsubishi GDI have?
The new engine is a V6 DOHC unit and sees a further evolution in the outstanding characteristics of the GDI concept. The new V6 3.5-liter GDI engine realizes a 30 percent improvement in fuel consumption, a 10 percent increase in power output (*2) and a 30 percent reduction in emissions of CO2, regarded a factor in global warming.
