EXPERIMENTAL OPERATION OF DIESEL AND GASOLINE ENGINE IN DUAL FUEL MODE USING PRODUCER GAS FROM WOOD CHARCOAL GASIFICATION

Wood charcoal gasification can produce low tar content in its producer gas. The producer gas is suitable to use in gasoline and diesel engine as fuel. This research aims to get the stability of producer gas from wood charcoal gasification and the savings of diesel and gasoline fuel in operating dual fuel engine. Tests were carried out on each electric load of 0 kW, 0.3 kW, 0.5 kW, 0.7 kW, 1 kW for diesel engines and 0 kW, 0.3 kW, 0.5 kW, 0.7 kW for gasoline engine. The test results showed that the wood charcoal gasification process took place at a air-fuel ratio were 1.7 – 2. The range of combustible gas stability was 91 – 105 min. Diesel and gasoline fuel consumption rate in dual fuel operation were 0.1 l/h to 0.2 l/h and 0.2 l/h to 0.37 l/h respectively. The average of diesel and gasoline fuel savings were each of 65.8 % and 19.8 % respectively.
