The addition of ethanol to a blend of vegetable oil (VO) and diesel, in general, has been found to improve the compression ignition diesel engine performance. In the present investigation, the influence of ethanol on Mesua ferrea Linn oil–diesel blend has been studied. Mesua ferrea Linn trees, abundant in the north eastern states of India, have the potential to supplement the fossil diesel. The blend studied is composed of 30% Mesua ferrea Linn oil and 70% diesel by volume (VO30). Ethanol is added 5 and 10% by volume to VO30 binary blend to form two ternary blend VO30E05 (5% ethanol and 95% VO30) and VO30E10 (10% ethanol and 90% VO30). Experiments have been carried out in a four-stroke, single cylinder, water cooled, stationary diesel engine at various engine loads. The addition of ethanol results in an increase of brake thermal efficiency up to 1.5% as compared to neat VO30. The brake specific fuel consumption of the engine increases on an average by 1.8 and 3% with the use of 5 and 10% ethanol, respectively. The use of ethanol results an increase of CO and HC emissions while a decrease of NO_X emission.

通常，已经发现在植物油（VO）和柴油的混合物中添加乙醇可以改善压燃式柴油发动机的性能。在本研究中，已经研究了乙醇对Mesua ferrea Linn油-柴油混合物的影响。Mesua ferrea Linn树木在印度东北各州盛产，有潜力补充化石柴油。研究的混合物由30％的Mesua ferrea组成亚麻油和70％体积比的柴油（VO30）。将乙醇按体积计5％和10％添加到VO30二元共混物中，以形成两种三元共混物VO30E05（5％乙醇和95％VO30）和VO30E10（10％乙醇和90％VO30）。实验是在四冲程，单缸，水冷，固定式柴油发动机上以各种发动机负荷进行的。与纯VO30相比，添加乙醇可使制动器的热效率提高多达1.5％。分别使用5％和10％的乙醇，发动机的制动比燃油平均平均增加1.8％和3％。乙醇的使用导致CO和HC排放增加，而NO _X排放减少。
