Abstract: The present investigation is carried out on Common Rail Diesel Injection (CRDI) engine at various loads. The research engine is operated with cotton seed oil blend (B20) as fuel at various fuel injection timings (IT). Initially run the engine at standard injection timing of 23° before top dead centre (BTDC), then operate the engine with retarded angle of 20° BTDC and advance angle of 26° BTDC. The B20 at injection timing of 23° BTDC showed higher Brake Thermal Efficiency (Bthe) when compared to the diesel and other injection timings. B20 with IT23 showed drastic reduction HC emissions about 50% when compared with the pure diesel operation. At injection timing 20° BTDC showed the clear reduction in NOX emissions when compared with the diesel
