Abstract
According to the importance of methanol as an alternative biofuel and the current research trends towards more advanced internal combustion (IC) engine, it is required to fully understand the combustion and emission characteristics of advanced compression ignition (CI) engines fueled with methanol. Biomethanol can be produced from various biomass such as agricultural waste, forestry waste, livestock and poultry waste, fishery waste and sewage sludge through pyrolysis, gasification, biosynthesis and electrolysis etc. The main concern in this review is the application of biomethanol to advanced CI engines such as HCCI (homogenous charge compression ignition), PPC (partially premixed combustion), DF (duel fuel), RCCI (reactivity controlled combustion ignition) combustion mode. This review is a part of an on-going review project of application of bioalcohols to the advanced CI engines. In this review, it is found that the method for HCCI combustion in CI engine fueled with biomethanol can be divided into three categories: i.e. external, internal, and combined mixture preparation. DF combustion mode can be divided into four categories, i.e. blends, emulsion, fumigation, and dual fuel injection. In DF combustion mode, dual fuel injection can also be divided by two strategies, i.e. 1) PFI of the methanol and DI of the diesel in cylinder, 2) PFI of the methanol and DI of straight vegetable oil, Of two techniques, the methanol PFI (port fuel injection) and diesel DI (direct injection) was the prevailing technique to be studied in the dual fuel combustion. RCCI combustion mode can be divided into three categories, i.e. 1) methanol PFI/diesel or biodiesel DI, single injection, 2) methanol PFI/diesel DI, double injection, 3) methanol PFI/ diesel DI, triple injection.
