Impact of Hydrogen Mixture on Fuel Consumption and Exhaust Gas Emissions in a Truck with Direct-Injection Diesel Engine

Performance and Exhaust Gas Emissions Analysis of Direct Injection Cng-diesel Dual Fuel Engine

Existing diesel engines are under stringent emission regulation particularly of smoke and particulate matter in their exhaust. Compressed Natural Gas and Diesel dual fuel operation is regarded as one of the best ways to control emissions from diesel engines and simultaneously saving petroleum based diesel fuel. Dual fuel engine is a conventional diesel engine which burn either gaseous fuel or d...

Impact of Methanol–Gasoline Fuel Blends on the Performance and Exhaust Emissions of a SI Engine

Reduction of emissions and fuel consumption of diesel engine by using common rail fuel injection and aftertreatment systems

In this experimental study, the fuel system of the OM364 diesel engine manufactured by IDEM company, which operates in the basic mode with inline fuel pump and mechanical governor control, is upgraded to a common rail system with electronic control by the ECU. Also, emmssion of exhaust gases is reduced by SCR and DOC catalysts then performance and emmission parameters of engine are compared i...

Combined effect of ignition and injection timing along with hydrogen enrichment to natural gas in a direct injection engine on performance and exhaust emission

To improve the engine performance and reduce emissions, factors such as changing ignition and injection timing along with converting of port injection system to direct injection in SI(spark-ignited) engines and hydrogen enrichment to CNG fuel at WOT conditions have a great importance. In this work, which was investigated experimentally (for CNG engine) and theoretically (for combustion Eddy Bre...

Dual Fuelling of a Direct Injection Automotive Diesel Engine by Diesel and Compressed Natural Gas

Application of Compressed Natural Gas (CNG) in diesel engines has always been important, especially in the field of automotive engineering. This is due to easy accessibility, better mixing quality and good combustion characteristics of the CNG fuel. In this study the application of CNG fuel along with diesel oil in a heavy duty direct-injection automotive diesel engine is experimentally investi...
