摘要
The effects of using diesel–methanol–dodecanol blends including methanol of various proportions on a CI engine performance are experimentally investigated. The methanol concentration in the blend has been changed from 2.5%to 15%with the increments of 2.5%, and 1%dodecanol was added into each blend to solve the phase separation problem. Experimental study has been conducted on a single-cylinder, water-cooled CI engine. The engine has been operated at different compression ratios (19, 21, 23 and 25) and the engine speed was varied from 1000 to 1600 rpm at each compression ratio. The performance parameters such as torque, effective power, specific fuel consumption and effective efficiency for each blend at various conditions are calculated depending on the experimental data. It was concluded that among the different blends, the blend including 10%methanol (DM10) is the most suited one for CI engines from the engine performance point of view. Improvements obtained up to 7%in performance parameters with this blend without any modification to engine design and fuel system are very promising.
