چکیده
T his paper has investigated the effects of an alternative hybrid hydrogen-gasohol E20 fueled spark ignition engine on performance and exhaust pollutants. A hydrogen mixture with gasohol was performed in external formation by installing a fuel injection kit into intake manifold area which is responsible for injecting inside engine’s cylinder. The energy fraction gradually increased from 3% to 9% degree range 20°, 25°, 30° 35° before top dead center were controlled using electronic control unit study optimal condition four-stroke single-cylinder engine. In steady-state test half-open throttle under variable load at 28%, 42%, 56%, 70% maximum torque, can be available satisfactorily average relative air-fuel ratio (λ) value 1.2 fuel. results indicated that when increase volume fraction. Postponing timing closer (TDC) 25° BTDC, brake power thermal efficiency increases. It also noted postponing caused NOx, HC CO emissions decrease. NOx as increased, whereas decreased.
