Summary, etc The Diesel or compression ignition (CI) engines are widely used for public transport as wellas transport of goods. For these applications, it is difficult to replace them with ElectricVehicles (EVs) in the near future due to the low energy density of current batteries. Blendingmineral diesel with renewable fuels like biodiesel can minimize the dependence on fossil fuelsand can lower the emissions. Blends containing up to 20% of biodiesel can be used without anymodification in the existing CI engines. To meet the current emission norms for CI engines,engine manufacturers usually use after-treatment systems to reduce NOx and particulate matter(PM) emissions. But the major drawback of these systems is that they do not operate efficientlywhen the exhaust gas temperature is below 250◦C, as in low-load condition. In this work, 1-Dengine simulation software, Lotus Engine Simulation (LES) is used to study the performanceand exhaust gas temperature of biodiesel-diesel blends in direct injection (DI) Diesel engine. Atfirst, the performance of a single cylinder Diesel engine under nominal valve closure timings hasbeen investigated using blends of biodiesel and diesel fuel. Different compositions of biodiesel,as available in literature are used and validated against the experimental data. The engineperformance in terms of brake power, brake specific fuel consumption and torque show goodagreement along with higher exhaust gas temperature as reported earlier. With the confidencegained, the modelling is extended to a multi cylinder Diesel engine. Investigations have beencarried out on the effect of Variable Valve Timing (VVT) concept applied to Intake ValveClosure (IVC) timing using diesel fuel and are validated with available data. The multi cylinderengine is then simulated under same RPM and brake mean effective pressure (bmep) usingbiodiesel blends. Biodiesel blends result in higher exhaust gas temperature as compared topure diesel for same extent of advancing or retarding the IVC. This leads to the finding thatfor effective operation of after treatment systems in CI engines under low load, biodiesel blendsare more effective than using pure diesel fue<br/>
