Summary:

High energy demand and environmental pollution leads to seekingof new, renewable and clean energy as biofuel and biomass. Thesefuels are abundant in tropical areas andagricultural-economic-based countries. Among various crops whichare used for biofuel, Jatropha Curcas L. Oil (JO) is morebeneficial and attractive as it is non-edible which is notcompetitive with food demand. In agricultural sector, the biomasswaste especially from rice production such as rice husk is atremendous resource in Cambodia. The combination of the use ofbiomass from rice husk (RH) and Jatropha Cake (JC) from the JOproduction in the gasification can produce more energy for theelectricity production especially in the remote and rural area. Inprevious research, some researchers have been investigated on theuse of JO in blending ratio, heated-neat condition and dual fuelcombustion of diesel and bio-digested biogas. The use of crude-neatJO and producing gas from the gasification has never conductingyet. In this study, mixed combustion of dual fuel of neat JO andproducing biogas (BG) in single cylinder, direct injectioncompression ignition engine was conducted at fixed injection timingθj = 17 °bTDC, with two mixing ratios of producing gasrpg = 25 and 50% in energy base as JOHBG25 and JOHBG50 at low,medium and high loads. The producing gas which composes ofhydrogen, carbon mono-oxide, methane, carbon dioxide, nitrogen andoxygen from the gasification was replaced by the simulated gas andwas fed from gas cylinder. In previous experiments, pressurehistories were recorded and engine outputs and combustioncharacteristics such as thermal efficiency, specific energyconsumption, rate of heat release, maximum pressure-rise rate,maximum heat-release rate were recorded and analyzed, and exhaustgas emissions were measured. From the results, at low load, JOHBG25is better for its thermal efficiency. Both dual fuels JOHBG25 and50 produced lower maximum pressure-rise rate, compared to JO anddiesel with similar brake specific energy consumption (BSEC). Inall loads, JOHBG25 and JOHBG50 produce higher CO and THC but lessNOx, opacity and smoke compared to JO anddiesel
