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]
All compression-ignition engines (e.g. diesel engines), and many spark-ignition engines (i.e. petrol (gasoline) engines, such as Otto or Wankel), use fuel injection of one kind or another. Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138 ) became available in the late 1930s and early 1940s, being the first fuel ...
The Smartstream G2.5 GDi is an inline 4-cylinder engine with both direct and multi-port injection and a 13.0:1 compression ratio; the engine makes 194 PS (191 hp; 143 kW) at 6,100 rpm and 25 kg⋅m (181 lb⋅ft; 245 N⋅m) of torque at 4,000 rpm in the Sonata, for the Azera and Cadenza the engine makes 198 PS (195 hp; 146 kW) at 6,100 rpm and ...
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
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 ...
Hyundai Motor Company has produced the following families of automobile engines. Gasoline engines use a naming system based on Greek letters. Spark Ignition (Gasoline) Straight-3. Epsilon ε - 0.8 L; Kappa κ - 1.0 L; Straight-4. Epsilon ε - 1.0/1.1 L; Kappa κ - 1.2/1.25/1.4/1.6 L; Alpha α - 1.3/1.4/1.5/1.6 L; Gamma γ - 1.4/1.6 L; Sirius ...
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 ...
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.
