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.

As a part of the Safety Test Facility Building initiated by ARAI, the bungee sled facility has been designed, setup and proven to meet the National and International Regulatory Requirements. The facility is being extensively used for Type Approval tests of safety belts, seats and their anchorages. The paper describes the capabilities of the facility, shares the first hand experience of the conflicting design considerations, infrastructure viz., civil structure, lighting, data acquisition, high speed videography and motion analysis software.
