This work is carried out to investigate combustion characteristics of a dual fuel (diesel-gas) engine at part loads, using a quasi-dimensional multi zone combustion model (MZCM) for the combustion of diesel fuel and a single zone model with detailed chemical kinetics for the combustion of natural gas fuel. Chemical kinetic mechanisms consist of 184 reactions with 50 species. This combustion mod...

Considering the disadvantages of gasoline and natural gas as mono-fuel in SI engines has made the researchers to improve the performance and reduce the pollutant as the advantages of the application of dual fuel engines. On the other hand, lean-burn in engine may lead to the reduced pollutant. In the present study various mixtures of gasoline and natural gas with the gasoline as the dominant fu...

Vegetable oil causes problem when used as fuel in compression ignition engines. This problem is due to high viscosity and low volatility of vegetable oils, which can be minimized by the process of transesterification. The relatively high cost of refined vegetable oils render the resulting fuels unable to compete with petroleum derived fuel. To reduce the cost of biodiesel a relatively low cost ...

Methane is a popular alternative fuel for internal combustion engines due to its availability in many forms such as methane hydrates, natural gas, biogas, compressed liquid synthetic and pipe gas. can be effectively used existing diesel dual-fuel mode with few modifications. Dual-fuel technology helps bridge conventional gaseous fuel-powered engines. The properties of methane, including higher ...

This paper was to examine the reliability and criticality of two dual-fuel marine engine systems compare them with a conventional diesel system utilization dynamic fault tree analysis. The results analysis for engines indicate that failure probability is 8.84% on average at 14,000 running hours whereas 8.48% engines. finding contrasts our intuition are higher risk compared Research findings, ob...

Recent research activities in the field of Diesel engines have shown the potential to reduce pollutant emissions and improve thermal efficiency by controlling fuel reactivity. However, understanding the impact of blending fuels with different physical and especially chemical properties on diesel-like spray mixing and combustion processes is still a challenge. Since the experimental techniques a...
