In this study, the ECU program of the OM 457 diesel engine manufactured by IDEM Co. has been recalibrated and SCR aftertreatment has been installed in the exhaust gas path of the engine, which finally, by maintaining the engine performance, its emission standard has been upgraded to Euro 5EEV and the fuel consumption of the engine has also been reduced. With this upgrade, the engine's CO2 emissions have also been reduced, which is effective in reducing greenhouse gases that cause global warming. Also, this upgrade was done without changing the engine design and only by recalibrating the ECU program, which also reduced the cost of the project. The basic OM 457 engine has the Euro 3 emission standard, which is installed on vehicles with DPF aftertreatment, which DPF has a high price, and also DPF is very sensitive to the sulfur in fuel, and the gasoil used in the country has high sulfur, causing early DPF failure. Now, with this upgrade of the engine emission standard to Euro 5 EEV without using DPF, the problem of price and sensitivity of DPF to sulfur has also been solved, and SCR aftertreatment is not sensitive to fuel sulfur.
