This paper presents a numerical study on the characteristic of combustion using mixed fuel (Diesel-Propane) in a compression ignition (CI) engine with EGR. Propane is often used as an alternative fuel in motor vehicles, especially in countries that want to reduce exhaust emissions. However, the addition of propane to the Internal Combustion Engine (ICE) causes the combustion temperature to increase. Increased temperature in the combustion chamber can trigger Nitrogen to react and cause NOx emissions. From the last experimental study on impact of EGR in a Compression Ignition Engine can reduce combustion temperature because inert gas such as Nitrogen (N2) from emissions can be used as inhibitors in the combustion process. This method is carried out with the aim of reducing oxygen in the atmosphere to inhibit the rate of the combustion reaction thereby reducing combustion temperature. There are few studies on the combustion characteristics of Diesel-Propane fuel with EGR. Diesel Fuel (90%) - Propane (10%), Diesel Fuel (80%) - Propane (20%), Diesel Fuel (70%) - Propane (30%), and pure Diesel Fuel with EGR and without EGR were used as fuel in this study. To ensure numerical results we are comparing them with experimental studies. Combustion characteristics including diesel fuel and propane blend were investigated and got the highest pressure in combustion chamber on the D9P1 without using EGR of 86.5419 bar in the combustion chamber. Adding propane can increase the pressure in the combustion chamber during combustion, but adding too much propane can reduce the performance of the IC engine. The usage of EGR during combustion process produces smaller pressure in combustion chamber than combustion without EGR.
