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]
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 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.
2011 Hyundai Sonata Limited 2.0T, turbo GDI engine. The first iteration of 2.0L T-GDI engine was used in the sixth generation Sonata and third generation Optima, compression ratio is 9.5:1 and the engine develops 261–278 PS (192–204 kW; 257–274 hp) at 6,000 rpm and 37.2 kg⋅m (269 lb⋅ft; 365 N⋅m) of torque between 1,750 rpm and 4,500 ...
Engine tuning is the adjustment or modification of the internal combustion engine or Engine Control Unit (ECU) to yield optimal performance and increase the engine's power output, economy, or durability. These goals may be mutually exclusive; an engine may be de-tuned with respect to output power in exchange for better economy or longer engine ...
The gasoline direct injection version of the 6G74 was launched in April 1997 as the first GDI V6 engine ever produced. It differed from the basic 6G74 in many ways apart from its unique fuel injection system—it had a crown-curved rather than flat piston head, upright intake ports rather than angled, and a 10.4:1 rather than a 10.0:1 ...
The first four-stroke direct-injection petrol engine for a passenger car was released the following year, in the Mercedes-Benz 300SL sports car. [41] However the engine suffered lubrication problems due to petrol diluting the engine oil, [42] [43] and subsequent Mercedes-Benz engines switched to a manifold injection design. Likewise, most ...
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 ...
