Abstract

Considering the growing demand for emission reduction, diesel engines are becoming more and more popular. CO2 can be further reduced by downsizing the engine. Engines in the range of 1.0 to 3.0 liter cubic capacity are being re-designed for high specific power in the range of 50 to 75 kW/l with peak firing pressure in the range of 160 to 200 bar, bsfc below 200 g/kWh and extremely low emissions to meet Euro V Norms and beyond. This paper highlights development strategies employed to meet this enhanced dynamic performance for such compact diesel engines. Some of the areas highlighted are design considerations, high performance crank train, cylinder head and cylinder block to meet high mechanical and thermal loading, air induction with 4 valve technology and VNT/Dual turbochargers, fuel injection with piezo multi stage common rail fuel injection and emission control technology. The use of diesel engine will continue with upward trend worldwide. With research efforts in material technology, induction, injection and combustion optimization and after-treatment devices, the future of diesel engines is looking bright and adaptable for wider range of applications.
