Summary:

Today the whole automotive world is progressively transforming towards the adoption of new alternate and innovative technologies evolving in ICE to meet the stringent emission regulations and future CO2 goals while protecting the environment; may it be a Electrification, Various degrees of hybridization, Alternate fuels, Engine downsizing, Cylinder deactivation or VVT et cetera The key to achieve better FE, reduction in CO2 or emissions is realized by saving every pie of energy spent or reducing the parasitic losses and improving engine efficiencies wherever possible. In this paper, an experimental study on the deployment of various energy saving technologies are exploited on small 2 Cylinder CRDI BSVI engine for friction reduction moving forward from BSIV to BSVI phase.In first step, Piston-Ring pack is optimized for energy saving potentials by design and surface coating modification approach. Design optimizations are done in balancer shaft to improve energy losses. With similar objectives, DLC coated tappets are used in valve train. To reduce hydraulic pumping energy at various speed loads, a 2 stage variable displacement oil pump (VOP) is used to supply the oilFor Cylinder liner surface, bore coatings are applicated which are Plasma spread MMC (Metal Matrix Composite) coatings. This technology reduces liner friction and oil consumption. This engine has first of its type in India having coating on cylinder liner surface. Finally a low-viscosity synthetic oil SAE 5W30 is also included in the friction reduction package.It has been demonstrated in this experiment that the whole package of friction reduction on an engine saves the engine energy by more than 14~15% in FHP over the base engine along with substantial improvement in engine power and @ 3% benefit in overall BSFC. This improves mechanical efficiency of BSVI engine by 8~9 % over the base configuration engine
