“…In some experimental and computational studies in the field of the RCCI, using natural gas and diesel or biodiesel has been studied considerably. [47][48][49][50][51][52][53][54] In the present work, the RCCI combustion with natural gas and diesel fuel in a heavy-duty diesel engine is simulated extensively in detail. The aim is to investigate the implications of a number of the combustion parameters to optimize such an engine efficiency, power output, and emission levels.…”

The aim of this study is to investigate in details the effects of a number of combustion parameters to optimize the reactivity controlled compression ignition operation running on natural gas and diesel fuel. In the present work, a singlecylinder heavy-duty diesel engine with a specially modified bathtub piston bowl profile for reactivity controlled compression ignition operation is studied and simulated through commercial software. A broad load range from 5.6 to 13.5 bar indicated mean effective pressure at a constant engine speed of 1300 r/min, fixed amount of diesel fuel mass, and with no exhaust gas recirculation is considered. The results from the developed model confirm that the model can accurately simulate the reactivity controlled compression ignition combustion. Also, by focusing on the time of formation of certain important radicals in combustion, the start of combustion and the time of natural gas dissociation are accurately predicted. Furthermore, the influence of some parameters such as different diesel fuel injection strategies, intake temperature, and intake pressure on the reactivity controlled compression ignition combustion is evaluated and the limitation of the engine operation at low temperature combustion is investigated.

“…High octane fuels or low reactivity with resistance to spontaneous ignition are more favorable for RCCI, PCCI and PPC combustion. For this reason, most of the studies carried out on RCCI, PCCI and PPC engines are focused on natural gas [89,[123][124][125][126][127][128][129][130][131][132][133] and ethanol [134][135][136][137][138][139][140][141][142][143][144] as an alternative fuel.…”

Researchers have studied on alternative fuels that can be used with gasoline and diesel fuels. Alternative fuels such as hydrogen, acetylene, natural gas, ethanol and biofuels also uses in internal combustion engines. Hydrogen in the gas phase is about 14 times lighter than the air. Moreover, it is the cleanest fuel in the world. On the other hand because of its high ignition limit (4-75%), low ignition energy, needs special design to use as pure hydrogen in internal combustion engines. It is proved that hydrogen improves the combustion, emissions and performance, when is added as 20% to fuels. Natural gas is generally consisting of methane (85-96%) and it can be used in both petrol and diesel engines. Ethanol can be used as pure fuel or mixed with different fuels in internal combustion engines. In this section, the effects of natural gas, hydrogen, natural gas + hydrogen (HCNG), ethanol, ethanol + gasoline, ethanol + hydrogen, acetylene, acetylene + gasoline mixtures on engine performance and emissions have been examined.

“…Due to comparatively larger cyclic variations in spark ignition engines, they are often main focus of investigation [5,6]. Stringent emission legislations and fuel economy requirements leads to investigation of cyclic variability in conventional compression ignition engines also [7][8][9] and as well as advanced premixed compression ignition engines [10]. Mostly experimental studies conducted have used statistical methods for cyclic variability analysis.…”

Current study focuses on cyclic variability analysis of indicated mean effective pressure (IMEP) and total heat release (THR) in a conventional single cylinder diesel engine using symbol sequence statistics. The objective is to characterize the cyclic variations and estimate the deterministic pattern in experimental data series. Results presented in this study can be beneficial for the design of effective control strategy. Experiments are performed at constant speed for five different engine operating conditions. Engine cylinder pressure data is acquired for 2500 consecutive cycles. Engine combustion parameters (IMEP and THR) are calculated from measured cylinder pressure on cycle to cycle basis and resulting data series is analyzed by symbol sequence method. Results revealed that selection of symbol sequence length and number of partitions is dependent on engine operating conditions and chosen combustion parameter.
