Abstract This paper examines the potential of using ammonia (NH $$_3$$ 3 ) as a primary fuel in heavy-duty engines for decarbonization, with some challenges yet to be addressed. It presents numerical study Reactivity Controlled Compression Ignition engine, where pilot diese...

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...

Recent investigations show that there are different combustion strategies promise to achieve higher efficiencies in internal engines. Advanced modes such as reactivity controlled compression ignition (RCCI) and dual-mode dual-fuel (DMDF) have proven be able low NOx soot engine-out emissions while being operate over the complete engine map. On another front, intensive research has been done fuel...

Gasoline compression ignition (GCI) has been shown as one of the advanced combustion concepts that could potentially provide a pathway to achieve cleaner and more efficient combustion engines. Fuel and air in GCI are not fully premixed compared to homogeneous charge compression ignition (HCCI), which is a completely kinetic-controlled combustion system. Therefore, the combustion phasing can be ...

In order to contribute to the solution of controlling the auto-ignition in a Homogeneous Charge Compression Ignition (HCCI) engine, parameters linked to External Gas Recirculation (EGR) seem to be of particular interest. Experiments performed with EGR present some difficulties in interpreting results using only the diluting and thermal aspect of EGR. Lately, the chemical aspect of EGR is taken ...

In order to directly control the premixed combustion phasing, a Jet Controlled Compression Ignition (JCCI) for diesel premixed compression ignition systems is investigated. Experiments were conducted on a single cylinder natural aspirated diesel engine without EGR at 3000 rpm. Numerical models were validated by load sweep experiments at fixed spark timing. Detailed combustion characteristics we...

The reduction of pollutant emissions from internal combustion engines, and in particular greenhouse gases, must be achieved by optimizing the process choosing fuels with a low carbon impact. Heterogeneous mixture combustions such as Diesel induce difficulty managing pollutants formation even if its principle output efficiency remains favorable. Therefore, it is necessary to distinguish this las...
