Cars with gasoline direct injection (GDI) have been especially prone to carbon buildup, and car makers recommend fuels with higher detergent levels to combat the problem. [18] At first GDI was mainly available in high-end autos, but it is now being used in mid-range cars and economy cars, such as the Hyundai Sonata, Ford Focus and Hyundai Accent.
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 fuel efficiency and working principle of a PPC engine resemble those of Diesel engine, but the PPC engine can be run with a variety of fuels. Also, the partially premixed charge burns clean. [6] Challenges with using gasoline in a PPC engine arise due to the low lubricity of gasoline and the low cetane value of gasoline.
Currently, Proton is planning to develop a new engine known as the code name "GDi/TGDi engine" with option of displacement between 1.0/1.2L three cylinders,1.3/1.5 naturally aspirated and turbocharged and progressively 2.0 L, 2.3 L all in the variant of either natural aspirated or in force induction type. The existing CamPro engines which are ...
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.
