Tikar, S., Marathe, A., Mulik, R., Ramdasi, S. et al., "Design Strategies for Development of a Series of Small Power Diesel Genset Engines for Future CPCB II Genset Emission Norms," SAE Technical Paper 2013-26-0132, 2013, doi:10.4271/2013-26-0132.
Small power diesel engines are most demanding product in Indian market for stationary applications like power genset, agricultural purpose etc. The upcoming 2013 CPCB emission norms for diesel genset engines below 19 kW power rating are the most stringent one in the world. There is a need not only to upgrade technologies pertinent to the latest emission norms but also to reduce the product cost.This paper presents various design strategies used to meet the desired engine performance and emission levels for development of a series of small power diesel genset engines having bore dia. ranging from 76 mm to 120 mm. Design and development of single and two cylinder NA diesel engines has been carried out with the help of CAD/CAE, design analysis tools, in-house developed algorithms and available statistical databaseSimulation codes are used for design analysis of engine subsystems like valve train, power train and flow analysis of air cooled engine in order to make the product technically and economically viable. Design verifications performed on several engine systems and sub-systems have been presented in the paper
