Abstract- The burnt gases from exhaust is pumped back in to the intake manifold through suitable piping to dilute the air fuel mixture is the concept of EGR which reduces the Cycle Temperature due to high specific heat(Cp). Low cycle temperature results in lower combustion rate and peak pressure. Moreover lower peak pressure leads to less heat transfer which improves the efficiency. In the presented experiments an EGR loop has been used circulating the burnt gas from the exhaust back into the intake piping. When running the engine with high amounts of EGR it is necessary to use a back pressure valve in the exhaust pipe to force the exhaust gases into the intake pipe. The down side is that the pumping losses will increase. A heat exchanger is attached to the EGR valve in order to cool the burnt gases. The amount of EGR is calculated from the CO2concentrations in the intake compared to the exhaust. Investigation is carried in two phases one is on EGR with different rates on CI engine and another is EGR on HCCI engine and comparison of results of effect of EGR on CI and HCCI Engine mode of operation.
