The Homogeneous Charge Compression Ignition is an alternative combustion technology that can reduce automobile pollution, provided that the exhaust emission can be controlled. A parametric study can be useful in order to gain more understanding in the emission reduction possibilities via this new combustion technology. For this purpose, the inlet temperature, the equivalence ratio and the compr...

An experimental study has been conducted to provide insight into heat transfer to the piston of a light-duty single-cylinder research engine under Conventional Diesel (CDC), Homogeneous Charge Compression Ignition (HCCI), and Reactivity Controlled Compression Ignition (RCCI) combustion regimes. Two fast-response surface thermocouples embedded in the piston top measured transient temperature. A ...

Reactivity Controlled Compression Ignition (RCCI), which is a low temperature combustion mode based on the principle of working with dual fuel, has attracted attention researchers in recent years due to its advantages such as high thermal efficiency, NOx and soot emissions, controllability combustion. In this study, effects injection timing lambda RCCI were investigated numerically by validatin...

In this study, we investigate the effect of different split injection strategies on ignition delay time (IDT) and heat release rate (HRR) characteristics in Reactivity Controlled Compression Ignition conditions via large-eddy simulation finite-rate chemistry. A diesel surrogate (n-dodecane) is injected into a domain with premixed methane oxidiser two separate pulses. Three are investigated by f...

This article demonstrates a feasible approach towards minimizing negative impact of combustion, which comprises low net carbon emissions operation internal combustion engines while achieving ultra-low engine-out exhaust emissions. Ultra-low emission was achieved by combining Reactivity Controlled Compression Ignition (RCCI) concept and the use an advanced fuel mix featuring life cycle consists ...

Environmental concerns over automotive exhaust emissions and consumer demand for higher fuel efficiency have led to the development of low-temperature combustion concepts. The reactivity-controlled compression ignition (RCCI) engine is one among them has potential reduce NOx smoke simultaneously. In this concept, a low-reactivity injected into intake port another high-reactivity cylinder direct...
