چکیده

Under the stress of environmental pollutions and fossil fuel consumption caused by on-road transport, hybrid vehicles are attracting much attention. Opposed rotary piston (ORP) engines a promising power source for vehicles, due to their compact designs high density. In this paper, combustion emission characteristics turbocharged ORP engine fuelled with hydrogen were investigated evaluate overall performance engine. The results indicated that volumetric efficiency was higher than 89.0% all given cases. Peak in-cylinder pressure in range 51.0 ~ 69.0 bar; 4000 RPM scenario had maximum value, being benefitted from intake temperature pressure, efficiency. Combustion duration ranged 27 43° crank angle (CA), phase happened at 7.5 13°CA after top dead centre (TDC). nitrogen monoxide (NO) formation rates corresponding 5 TDC; accumulated NO decreased slightly reaching peak value low speed conditions. Discharge start exhaust stroke 6.0 bar, especially 5000 case whose approximately 11.0 bar. This presented excellent torque characteristics, density 104.0 kW·L−1 which four-stroke reciprocating gasoline.

Exhaust Emission Analysis of an Internal Combustion Engine Fuelled with Hydrogen-Ethanol Dual Fuel

The work presented in this paper is an attempt to evaluate the exhaust emission characteristics of a hydrogen-ethanol dual fuel combination with different percents of hydrogen substitutions (i.e. 0-80 % by volume and of 20 % increment ) at three different compression ratios of 7:1, 9:1 and 11:1. Experimental investigations have been carried out on a computer interfaced with; four-stroke cycle, ...

Numerical Simulation of Combustion with Porous Medium in I.C. Engine

Porous media has interesting features in compared with free flame combustion due to the extended of the lean flammability limits and lower emissions. Advanced new generation of internal combustion (IC) engines are expected to have far better emissions levels both gaseous and particulate matter, at the same time having far lower fuel consumption on a wide range of operating condition. These c...

Knock and Combustion Rate Interaction in a Hydrogen Fuelled Combustion Engine

The paper describes correlation between combustion knock intensity and combustion rate calculated as the heat release rate from combustion pressure traces of a hydrogen fuelled spark ignited engine. Unlike a gasoline spark ignited (SI) engine, the hydrogen fuelled engine can easily generate knock during combustion at working conditions similar to a gasoline engine. However, the hydrogen knock d...
