چکیده

In this study, the effects of adding ethanol and diethyl ether to diesel fuel on combustion characteristics NO emissions were numerically investigated. 100% (D100) by volume 90% diesel+10% blend (D90E10), 80% diesel+20% (D80E20), ethanol+10% (D80E10DEE10) 85% diesel+ 10% ethanol+5% mixture (D85E10DEE5) was used as fuel. Analyzes carried out using a single cylinder direct injection engine at 2000 3000 rpm speed conditions. AVL FIRE software for numerical study. In-cylinder pressure, cumulative heat release rate, turbulent kinetic energy (TKE), velocity distributions in chamber investigated five different types. As result, in-cylinder pressure rate blended fuels lower than both speeds. This is due calorific value It observed that decreased content increased. For speeds, highest TKE obtained D90E10 mixed fuel, lowest found D80E10DEE10 Ethanol positively affected energy. The flow higher

Numerical Investigation on the Effect of Injection Timing on Combustion and Emissions in a DI Diesel Engine at Low Temperature Combustion Condition

One promising way to achieve low temperature combustion regime is the use of a large amount of cooled EGR. In this paper, the effect of injection timing on low temperature combustion process and emissions were investigated via three dimensional computational fluid dynamics (CFD) procedures in a DI diesel engine using high EGR rates. The results show when increasing EGR from low levels to levels...
