An Effect of Biodiesel on Compression Ignition Engine Vibration -A Review

There has been a continuous demand of conventional fuels for the transport sector. But we only have a limited amount of fossil fuels. The fossil fuels are a non-renewable source of energy. Moreover, in the developing countries diesel engines are used to produce electricity or in the agricultural land. As the fossil fuels are depleting day by day we need to have an alternate source of fuel. Biodiesel, which is a renewable energy, and has similar properties like the conventional diesel fuel. Biodiesel also has more oxygen content which helps in reducing the CO and HC in the exhaust emission. As Biodiesel is a new fuel which is being discovered, the performance of the engine is an important issue. The performance of the engine can be affected by combustion, excess vibration in the engine body or because of the fuel mixture. Engine vibration is a major disadvantage as it reduces the efficiency of the engine and too much of the vibration can lead to catastrophic effect. This paper focuses on the engine vibration which are caused by the different biofuel blends. It also focuses on how with the injection of hydrogen in the intake manifold can change the level of vibration.
