Numerical Study of Reactivity Controlled Compression Ignition (RCCI) Combustion in a Heavy-Duty Diesel Engine Using 3D-CFD Coupled with Chemical Kinetics
In this paper, a numerical study is performed to provide the combustion and emission characteristics resulting from fuel-reactivity controlled compression ignition (RCCI) combustion mode in a heavy-duty, single-cylinder diesel engine with gasoline and diesel fuels. In RCCI strategy in-cylinder fuel blending is used to develop fuel reactivity gradients in the combustion chamber that result in a ...
متن کاملThe effect of hydrogen and nitrogen addition on heavy duty diesel engine emissions under reactivity controlled compression ignition combustion
The aim of this study is to evaluate a heavy duty diesel engine operation under reactivity controlled compression ignition combustion fueled with diesel oil and natural gas enriched with hydrogen and nitrogen addition. In this study, a single cylinder heavy– duty diesel engine is set to operate at 9.4bar gross IMEP (Mid- Load). The amount of injected diesel oil per cycle into the engine combust...
متن کاملEffect of Injection Characteristics on Emissions and Combustion of a Gasoline Fuelled Partially-premixed Compression Ignition Engine
Conventional compression ignition (CI) engines are known for their high thermal efficiency compared to spark ignited (SI) engines. Gasoline because of its higher ignition delay has much lower soot emission in comparison with diesel fuel. Using double injection strategy reduces the maximum heat release rate that leads to NOx emission reduction. In this paper, a numerical study of a gasoline fuel...
متن کاملAbnormal Combustion Detection in a Compression Ignition Engine
Abnormal combustion occurrences in compression ignition engines are one of the main causes of engine failures, which severely affect the continuity of transportation operations. The detection of these occurrences may help to take measures to minimize the engine failures and increase engine life. In this work, we implement a machine learning system for abnormal combustion detection system in a s...
متن کاملInvestigating the effects of fuel injection strategies in a dual-fuel diesel-H2 compression ignition engine
In this computational research, the separate and simultaneous impacts of diesel direct injection timing, fuel spraying cone angle, and hydrogen gas addition on combustion characteristics, output emissions, and performance in a single-cylinder direct injection diesel engine was studied. In order to conduct the simulations, valid and reliable models for combustion, break-up, and for turbulence wa...
