In this paper we demonstrate the potential of combining electric hybridization with a dual-fuel natural gas-Diesel engine. We show that carbon dioxide emissions can be reduced to 43 gram per kilometer with a subcompact car on the New European Driving Cycle (NEDC). The vehicle is operated in charge-sustaining mode, which means that all energy is provided by the fuel. The result is obtained by ha...

Abstract To further investigate the performance of glycol/diesel dual-fuel engine, we conducted a simulation test by varying injection advance angle diesel engine. Thus, investigated effect different angles on Simulation tests were to study effects ethylene engine when mixing ratio was 15% and 14.6°, 16.6°, 18.6° 20.6°, respectively. The research shows that fuel increases in-cylinder temperatur...

In this study it has been tried, to compare results and convergence rate of sensitivity analysis and conjugate gradient algorithms to reduce fuel consumption and increasing engine performance by optimizing the timing of opening and closing valves in XU7/L3 engine. In this study, considering the strength and accuracy of simulation GT-POWER software in researches on the internal combustion engine...

Hydrogen, as a suitable and clean energy carrier, has been long considered primary fuel or in combination with other conventional fuels such gasoline diesel. Since the density of hydrogen is very low, port fuel-injection configuration, engine’s volumetric efficiency reduces due to replacement by intake air. Therefore, direct in-cylinder injection (injection after valve closes) can be solution f...

Climate change brought about by the emission of Greenhouse Gases (GHG) has shone a spotlight on role internal combustion engine. These engines are significant contributors to GHG emissions. However, there have been recent improvements in their design. Natural gas produces lower emissions during combustion, making it suitable as fuel engines. Aside from impact gasoline and diesel, collapse Niger...

The lean-burn capability of the Diesel-ignited gas engine combined with its potential for high efficiency and low CO2 emissions makes this engine concept one of the most promising alternative fuel converters for passenger cars. Instead of using a spark plug, the ignition relies on the compression-ignited Diesel fuel providing ignition centers for the homogeneous air-gas mixture. In this study t...
