Study on the controlling strategies of homogeneous charge compression ignition combustion with fuel of dimethyl ether and methanol

Study of dimethyl ether homogeneous charge compression ignition combustion process using a multi-dimensional computational fluid dynamics model

“…Flowers et al [10] used chemical kinetics code to analyze the natural gas HCCI combustion process, and DME addition was adopted as a control strategy. Yao et al [11,12] applied DME as an ignition improver for both Compressed Natural Gas (CNG) and Methanol HCCI combustion processes.…”

Homogeneous Charge Compression Ignition (HCCI) Combustion Engine- A Review

“…The mixture enters into the cylinder during the suction stroke and the turbulence generated by intake flow improves further homogeneity. This method of mixture preparation has been found to be quite successful with gasoline and alcoholic fuels [26][27][28][29][30][31][32][33]. The main demerit of this strategy is that the start of combustion cannot be controlled by the injection timing.…”

Investigation of the LTC fuel performance index for oxygenated reference fuel blends

“…Other groups investigated the behavior of alcohols in HCCI engines, including neat butanol [20] and ethanol [20,[24][25][26]; wet ethanol also received significant attention as a neat fuel due to the potential for increased overall energy efficiency by avoiding or reducing distillation and dehydration [27][28][29]. The low reactivity of alcohols such as ethanol and methanol motivated additional research into operating HCCI engines using blends with more reactive fuels/additives such as n-heptane [30], diethyl ether [31,32], dimethyl ether [33][34][35][36], and di-tertiary butyl peroxide [37]. In the opposite direction, other efforts studied injecting water into the engine cylinder to temper the reactivity of highly reactive fuels [33,[38][39][40][41].…”
