“…In this work, specific temperature is used as the threshold value for transition from ignition to combustion. The ignition delay time is supposed as a period when the cell temperature is less than 1100 K [12,29] and this phase is controlled chemically. The ignition model was used to consider low temperature combustion [29].…”

“…Various researchers have investigated the HCCI engine both experimentally [45][46][47][48] and numerically [45,[49][50][51]. Many numerical studies used a computational fluid dynamics (CFD) approach to obtain more accurate results of combustion temperature and products [52][53][54][55][56][57][58][59]. A CFD approach uses more computational power and time compared to a single-zone thermodynamics simulation.…”

Homogeneous charge compression ignition (HCCI) engine technology is relatively new and the combustion behavior in an HCCI engine is difficult to predict. The combustion is fully controlled by the chemical kinetics and the chemical reaction of the mixture is influenced by changing input parameters. A zero-dimensional single-zone model was used to investigate the combustion behavior of a diesel engine operating in HCCI mode. An open source chemical kinetics package from Cantera was used in this study. The combustion behaviour can be observed, where H2O2 was fully decomposed during the main combustion event. The time for H2O2 to completely decompose into OH radicals was very short, which was about 5°CA. The combustion phasing was predicted in accordance with the experiment. The auto-ignition can be controlled by controlling the intake temperature or AFR. The start of combustion was advanced by increasing the intake temperature from 20 to 70°C and reducing the AFR from 58 to 29. However, reducing AFR will increase the in-cylinder peak pressure. In general, a zero-dimensional model is a useful and faster tool to predict the combustion phasing. When coupled with chemical kinetics, it provides more accurate results.

“…In various methods for reducing both NOx and particulate emissions in diesel engines, natural gas (Agarwal, et al [ 1 ] ), dimethyl-ether (Kajitani, et al [2,3 ] ), methanol (Ishida, et al [4]), and Fischer-Tropsch diesel fuel (Johnson,et al[5]) have been investigated as alternative fuels for low emission diesel engines. Recent researches into NOx reduction and thermal efficiency improvement in diesel engines have shown that a homogeneous charge compression ignition (HCCI) will be a promising way to accomplish these targets.…”

: Fundamental concept for low emission engines in the present study is utilization of alternative fuels such as natural gas and methanol with low evaporation temperature for reducing smoke, and high EGR engine operation for reducing NOx. The final goal is to achieve the extremely low levels of both NOx and smoke without deteriorating high thermal efficiency in a dual fuel diesel engine. Natural gas or methanol was charged into the suction air, and a small amount of gas oil as an ignition source was injected directly into the combustion chamber of a four-cylinder DI diesel engine. The injection amount of gas oil, intake temperature, compression ratio and EGR ratio were changed in the experiments. The effects of these parameters on ignition delay, maximum rate of heat release, knock limit and misfire limit were clarified for the premixture of natural gas or methanol respectively.
