The 1996 Japanese-market Mitsubishi Galant was the first mass-produced car to use a GDI engine, when a GDI version of the Mitsubishi 4G93 inline-four engine was introduced. [52] [53] It was subsequently brought to Europe in 1997 in the Carisma. [54] It also developed the first six-cylinder GDI engine, the Mitsubishi 6G74 V6 engine, in 1997. [55]
The first four-stroke direct-injection petrol engine for a passenger car was released the following year, in the Mercedes-Benz 300SL sports car. [38] However the engine suffered lubrication problems due to petrol diluting the engine oil, [39] [40] and subsequent Mercedes-Benz engines switched to a manifold injection design. Likewise, most ...
The Omega Ω is a V8 engine produced by Hyundai Motor Company. It is a dual overhead cam design with electronic multiport fuel injection or gasoline direct injection . GDi
The Smartstream G1.0 T-GDI is a turbocharged inline 3-cylinder engine with gasoline direct injection (GDi); the engine makes 120 PS (118 hp; 88 kW) at 6,000 rpm and 17.5 kg⋅m (127 lb⋅ft; 172 N⋅m) of torque between 1,500 and 4,000 rpm. A detuned version with 100 PS (99 hp; 74 kW) between 4,500 and 6,000 rpm is also available for some ...
Indirect injection engines also tend to produce lower amounts of particulate matter compared to direct injection engines as the fuel and air are more uniformly mixed. Indirect injection using pre-combustion chambers are also used in high performance engines, such as those in Formula 1 , where they can allow the engine to produce more power with ...
In an HCCI engine, however, the homogeneous mixture of fuel and air is compressed and combustion begins whenever sufficient pressure and temperature are reached. This means that no well-defined combustion initiator provides direct control. Engines must be designed so that ignition conditions occur at the desired timing.
Either engine control units are reprogrammed to operate more efficiently, [23] or sensors that influence the ECU's operation are modified or 'simulated' to cause it to operate in a more efficient manner. Oxygen sensor simulators allow fuel-economy reducing catalytic converters to be removed. [24] Such devices are often sold for "off-road use ...
The most efficient cycle is the Atkinson Cycle, but most gasoline engine makers use the Otto Cycle for higher power and torque. Some engine design, such as Mazda's Skyactiv-G and some hybrid engines designed by Toyota utilize the Atkinson and Otto cycles together with an electric motor/generator and a traction storage battery.
