Further reductions in fuel consumption are anticipated as a result of a combination of the above with supercharging strategies and downsizing measures. In the following section, the thermodynamic aspects of gasoline direct injection are explained and the various combustion processes are described and compared. This is followed by an overview of engines with gasoline direct injection together with an indication of where future developments are leading. 2 Thermodynamic and combustion process Nowadays, modern diesel engines are equipped with direct fuel injection and most of these are supported by forced induction, which means that they can achieve a favourable level of fuel consumption.
2007). 4 Future trends Future developments in the area of combustion engines will concentrate on further reductions in fuel consumption and pollutant emissions. Gasoline direct injection technology will play a significant role in achieving this. The first engines with spray-guided combustion systems were launched in 2006. It can be assumed that in the next few years, other manufacturers will follow by producing engines with second-generation direct injection systems. Gasoline direct injection with turbocharging is an ideal combination for Stratified-charge combustion in DI gasoline engines 43 increasing the efficiency of the engines.
Although the peak cycle cylinder average temperature is reduced due to the overall leanburn charge, combustion temperature in the stratified charge remains high and becomes higher than the homogeneous charge as combustion takes place at elevated pressure without throttle operation. Furthermore, NOx emission increases with advanced combustion timing, which is sometimes necessary to achieve stable stratified charge combustion by catching the near-stoichiometric mixture formed soon after the end of injection.
