Engine Development

The Automotive Research Association of India (ARAI) offers comprehensive services in the automotive field. Engine Development Laboratory (EDL) is one of the major R&D divisions of ARAI. EDL provides comprehensive engine design, emission control and testing expertise for diesel, gasoline, CNG, LPG, bio-diesel and ethanol engines. EDL undertakes projects for enhancing the power density and fuel economy and reducing emissions from engines used in 2 and 3 wheelers, cars, LCV and HCV, tractors, off-highway and genset applications. Services offered: concept design and detailed engineering; computational simulation based on advanced software; combustion optimisation, port development and matching; emission reduction to meet Euro, EPA and Indian norms; mechanical design of components, dynamic analysis of power train and valve train system; conversion of diesel and gasoline engines to CNG and LPG fuels; and feasibility study, durability testing, localisation programs, etc. EDL is equipped with the following state-of-the-art facilities: CFD software packages – FIRE, Swift, Fluent; design and analysis software – Excite Designer, Tycon, Glide, Hydsim, GT-Crank, GT-Vtrain, GT-Fuel, GT-Cool performance and emission simulation software – Boost, Cruise, GT-Power, GT-Drive. Transient engine test beds; raw and dilute emission system with integrated FTIR facility to measure unregulated gaseous species; partial flow measurement of diesel particulate; full flow dilution tunnel with CVS for heavy duty engine emission and particulate measurement; swirl and flow test rig; and high speed data acquisition for combustion and injection line pressures, injector lift, valve motion, torsional vibration, etc.
