Effects of Air Intake Pressure to the Engine Performance, Fuel Economy and Exhaust Emissions on a Small Gasoline Engine

The study presents the engine performance, fuel economy and exhaust emissions at variations of air intake pressure. In carburetor system, the air intake pressure is influenced by the degree of opening throttle plate and venturi effect which draw the fuel to the combustion chamber. The ex...
