Characteristics of 1500 CC LPG fueled engine at various of mixer venturi area applied on Tesla A-100 LPG vaporizer

In the first generation of lpg kit,are called converter and mixer (cm),the engine power is influenced strongly by the size of mixer venturi,but this case has not been widely discussed. lpg has lower carbon content than gasoline,so it requires less air to burn. theoretically,the amount of air to burn lpg is 46% lower than gasoline. however,in practice,the venturi area of the mixer is made from 7.5 mm2 to 10 mm2 per output hp engine. to confirm this,the mixers with venturi area of 705,960,and 1256 mm2 are applied in toyota 5a-fe lpg-fueled engine with tesla a-100 lpg vaporizer. the engine performance characteristics were tested using the hofmann dynatest pro chassis dynamometer and the emissions were tested using qro-401 engine gas analyzer. the result shows that the venturi area of the mixer has a major influence on the engine power,which generates specific power characteristics. however,differences in the mixer size have little effect on emissions. this study concluded that the toyota 5a-fe lpg-fueled engine is recommended to use a mixer with venturi area of 960 mm2 (35 mm in diameter). � 2016,penerbit utm press. all rights reserved.
