Design and Development of 3- Cylinder: 75 kW/liter, High Power Density Diesel Engine for Passenger Car Application to Meet Euro IV/V Emission Norms 2011-26-0033

To meet the latest trends in internal combustion engines pertaining efficiency, emissions and durability, downsizing of the engine has become the key focus area. This paper describes about a robust, reliable and an integrated approach used in design and development of state of art high power density/ high speed engine developed from the concept, which can be adopted for passenger car and LCV application.
A three-cylinder, 1.5 liter displacement diesel engine, fully balanced is being designed with an objective to produce 115kW @ 4200 rpm, delivering a specific power output over 75 kW/liter, which is at par with a contemporary class of specification in it. In the first stage, a derated version of 75 kW (50 kW/liter) with Euro-IV and Euro-V specifications is targeted aiming at smaller car and light motor vehicle segment and a prime-mover for hybrid application.
This paper outlines various technologies applied in developing this engine to achieve high power density, low exhaust emissions, and low noise and vibration characteristics.
Major thrust has given on mechanical design and manufacturing aspects and have been discussed in this paper.
