“…The experimental results from Zhang et al 38 in a heavy-duty engine fueled by gasoline/HCB blends were employed to validate the above models. The experiment was conducted on a four-cylinder high-speed direct-injection (HSDI) heavy-duty diesel engine with different HCB blended ratios.…”

“…The detailed information on the engine can be found in For the detailed chemistry calculations, the CHEMKIN solver, 50 coupled with the KIVA@DUT code, was employed. For the HCB fuel and the China 95 # gasoline used in the experiment, 38 skeletal oxidation mechanisms of n-C 16 H 34 , 51 and primary reference fuel (PRF95) 52 were adopted to predict the combustion characteristics owing to their similar chemical properties, respectively. Both mechanisms were developed by the decoupling methodology, which can be divided into two parts: one is a skeletal mechanism for C 2 -C n ; the other is a detailed mechanism for H 2 /CO/C 1 .…”

“…Experimental and numerical studies on a heavy-duty diesel engine fueled by gasoline/HCB blends were conducted by our previous work. 37,38 The results indicated that NO x , CO, and HC emissions could be effectively reduced as the HCB blended ratio increases with a penalty of the slightly increased particulate matter emissions. In addition, it is also pointed out that the stable operating range of the GCI engine is very limited to the engine noise even at low loads.…”

Multiple-objective optimization of a heavy-duty compression ignition engine fueled by gasoline/hydrogenated catalytic biodiesel (HCB) blends at low loads was performed by employing the KIVA-3V code and genetic algorithm. In addition, the mechanism of multiple-injection and sensitivity of operating parameters on engine performance of the optimal cases were also explored. The results indicated that efficient combustions for G70H30 (70% gasoline and 30% HCB) and G100 (pure gasoline) with ultra-low nitrogen oxides (NOx) and soot emissions could be obtained after optimization. As HCB fraction increases, the ranges of operating parameters become more extensive, and the required initial temperature for optimal cases can be effectively reduced. When the main injection occurs after the ignition caused by pilot injection, main injection moderates the heat release rate (HRR) by creating concentration and temperature stratifications in the spray area simultaneously, and the exhaust gas recirculation (EGR) rate, pilot, and main start of injections and pilot fraction play dominant roles on engine performance. Moreover, when main injection is much more advanced than the ignition timing, main injection controls the HRR only through the concentration stratification in the reaction zone, and the EGR rate, initial temperature, and pilot faction have dominated effects on engine performance.

“…As the proportion of gasoline increases, soot emissions becomes insensitive to the change of intake oxygen concentration and remains at a low level with the gradual reduction of NO X emissions. A kind of second-generation hydrogenated catalytic biodiesel (HCB) with high reactivity was added to gasoline by Zhang et al, 21 the results show that with the increase of the HCB ratio, the GCI ignition performance and combustion stability at low is significantly improved. Kim and Bae 22 studied the effect of injection strategy on GCI.…”

Gasoline compression ignition (GCI) is an effective way to achieve both high thermal efficiency and low emission. The combustion and emission performances of GCI and DCI (diesel compression ignition) were compared on a 2.0 L diesel engine equipped with Three-way catalyst-Lean NOx trap/Passive selective catalytic reduction (TWC-LNT/PSCR) aftertreatment system. In order to further clarify the advantages and disadvantages of GCI, this paper first studies the combustion and emission at 1500 rpm and braking average effective pressure (BMEP) of 4–9 bar. Secondly, six small map points of worldwide harmonized light vehicles test cycle (WLTC) are studied. The results show that the braking thermal efficiency (BTE) of GCI is lower than that of DCI at low load. When BMEP is greater than 5 bar, the BTE of GCI is significantly improved. GCI achieves a maximum BTE of 43%, which is 3% higher than DCI. Compared with DCI, the NOx emission of GCI is slightly lower, the smoke emission of filter smoke number (FSN) is significantly improved, and the CO and HC emissions are significantly increased. GCI engine equipped with TWC-LNT/PSCR system with high aftertreatment efficiency has the potential to meet China’s VI B emission regulations.

“…For the nano-biodiesel blends, HC was drastically reduced and NOx and CO emissions were considerably reduced. Zhang et al [32] considered blends of hydrogenated catalytic biodiesel (HCB) derived from waste cooking oil and China's gasoline at different ratios. Gasoline compression ignition (GCI) engines are gaining more attention due to their high thermal efficiency and lower harmful emissions.…”

Biodiesel is a renewable energy source which is gaining prominence as an alternative fuel over fossil diesel for different applications. Due to their higher viscosity and lower volatility, biodiesels are blended with diesel in various proportions. B20 blends are viable and sustainable solutions in diesel engines with acceptable engine performance as they can replace 20% fossil fuel usage. Biodiesel blends are slightly viscous as compared with diesel and can be used in common rail direct injection (CRDI) engines which provide high pressure injection using an electronic control unit (ECU) with fuel flexibility. In view of this, B20 blends of three biodiesels derived from cashew nutshell (CHNOB (B20)), jackfruit seed (JACKSOB (B20)), and Jamun seed (JAMNSOB (B20)) oils are used in a modified single-cylinder high-pressure-assisted CRDI diesel engine. At a BP of 5.2 kW, for JAMNSOB (B20) operation, BTE, NOx, and PP increased 4.04%, 0.56%, and 5.4%, respectively, and smoke, HC, CO, ID, and CD decreased 5.12%, 6.25%, 2.75%, 5.15%, and 6.25%, respectively, as compared with jackfruit B20 operation.
