在一台单缸大功率柴油机上进行了聚甲醛二甲醚（PODE）作为直喷式高反应性燃料在双燃料反应性控制压燃（RCCI）工况下的试验研究。对汽油/柴油和汽油/PODE RCCI工况的燃烧和排放特性以及燃烧相位可控性进行了比较和讨论。结果表明，采用PODE作为DI高反应性燃料，可以实现稳定可控的RCCI运行。改进的指示热效率（ITE）和超低烟可以实现PODE，轻微的惩罚，但仍然相当的氮氧化物排放。单次喷射时汽油/PODE工况的最大负荷可达1.76 MPa，明显高于优化后的双次喷射时汽油/柴油工况的最大负荷（1.39 MPa），同时仍保持超低烟度和相当的ITE和PPRR。化学计量和清洁汽油/PODE双燃料RCCI操作也可以在高负荷下实现。这使得应用低成本的三元催化剂来进一步减少NOx、HC和CO排放成为可能，这为实现清洁高效的柴油燃烧提供了一条非常有竞争力的途径。
An experimental investigation has been conducted to explore the effects of polyoxymethylene dimethyl ethers (PODE) as the direct-injection (DI) high reactivity fuel in dual-fuel reactivity controlled compression ignition (RCCI) operation on a single-cylinder, heavy-duty diesel engine. The combustion and emission characteristics, together with the combustion phasing controllability of gasoline/diesel and gasoline/PODE RCCI operation are compared and discussed. The results show that stable and controllable RCCI operation is obtainable using PODE as the DI high reactivity fuel. Improved indicated thermal efficiency (ITE) and ultra-low smoke can be achieved with PODE, with a slight penalty, but still comparable NOx emissions. The maximum load of gasoline/PODE operation could be extended to 1.76 MPa indicated mean effective pressure (IMEP) with a single injection strategy, which is significantly higher than that of gasoline/diesel operation with an optimized double-injection strategy (1.39 MPa IMEP), while still maintaining ultra-low smoke and comparable ITE and PPRR. Stoichiometric and clean gasoline/PODE dual-fuel RCCI operation was also achievable at high load. This enables the possibility to apply a low-cost three-way catalyst to further reduce the NOx, HC and CO emissions, which offers a very competitive pathway to achieve clean and highly efficient diesel combustion.
