The fuel saving effects of emulsions in diesels used at home and abroad are described.The test results of emulsions obtained in high power medium speed and high speed single cylinder diesels are given.A lot of tests have been carried out by using emulsions in high power medium speed and high speed single cylinder diesels.The fuel savings have been proven.The maximum average saving of the order of 3.46% may be achieved by using emulsified fuels in high power medium speed single cylinder diesel of model 280.The maximum decrement of exhaust gas temperature was 50℃.The variation of explosive pressure is not distinct.In high power high speed single cylinder diesel of model 200 the maximum average saving of the order of 2.28% was recorded.The exhaust temperature lowers 40℃. But maximum increment of explosive pressure of the order of 1.5% was achieved.
