An evaluation was performed on the efficiency and emissions from an engine fuelled with compressed natural gas (CNG …) and a mixture of natural gas and hydrogen, respectively. The mixtures of CNG and hydrogen were named HCNG. …

misfiring. Opacity and NO emissions were also analyzed in detail. In the case with maximum EGR, the lowest average opacity …

Hydrogen-fueled internal combustion engines are considered to be more efficient and cleaner alternatives to their …, control and optimization of hydrogen engines. To serve for this broader purpose, a computational model, which has been widely … used for gasoline and diesel engines, is investigated for its capability to simulate hydrogen engines. Specifically, fuel …

performance at low load conditions. This paper experimentally investigated the co-effect of cylinder cutoff and hydrogen addition … on improving the performance of a gasoline-fueled SI engine. The experiment was conducted on a modified four-cylinder SI … engine equipped with an electronically controlled hydrogen injection system and a hybrid electronic control unit. The engine …

This paper compared the effects of hydrogen and hydrogen–oxygen blends (hydroxygen) additions on the performance of a …. HC emissions were reduced whereas NOx emissions were raised with the increase of hydrogen and hydroxygen addition levels … engine equipped with a hydrogen and oxygen injection system. A hybrid electronic control unit was applied to adjust the …

performance of a hydrogen-blended methanol engine at lean and various load conditions. The test was conducted on a four … in the intake of 0 and 3% were adopted to investigate the effect of hydrogen addition on combustion and emissions … performance of the methanol engine. The test results showed that brake thermal efficiency was improved after the hydrogen addition …

combustion, performance and exhaust emissions, using a blend of 20% POME (pongamia oil methyl ester) by volume in diesel were …Improved thermal efficiency, reduction in fuel consumption and pollutant emissions from biodiesel fueled diesel engines … operated at higher injection pressure. Substantial improvements in reduction of emissions levels were also observed for TRCC …

An experimental study is conducted to evaluate the performance and exhaust emissions characteristics of diesel fuel … regulated gas emissions such as nitrogen oxides, carbon monoxide and unburned hydrocarbons are measured. The differences in the … performance and exhaust emission parameters of the three DEE/diesel fuel blends from the baseline operation of the diesel engine …
