For carried out this work, a 6 cylinder four stroke engine with gamma technologies power software is modelled and the effect of compression ratio (15:1 - 19:1) and alternative fuels (Diesel, Ethanol, Methanol, Decane, Soybean biodiesel, Diesel- Ethanol) at wide open throttle and various speeds from 800-2400 rpm are presented. The results indicate that the brake speciļ¬c fuel consumptions of decane fuel at a compression ratio of 17:1 is lower than those of other fuels and also the maximum brake torque obtained with decane fuel at 1400 rpm. At this engine observed that decane fuel has higher brake power as compared to other fuels used due to higher heating value content. The emission results show that diesel fuel emitted more Carbon monoxide and Carbon dioxide emissions but soybean biodiesel (B100) has less Carbon monoxide, whereas highest oxides of nitrogen is founded with soybean biodiesel. Carbon monoxide and Carbon dioxide emissions are very close to each other when used decane and diesel fuel. In general decane fuel has higher performance and soybean biodiesel had fewer emissions at a compression ratio of 17:1.
