Effects of air intake pressure to the fuel economy and exhaust emissions on a small SI engine

This study discusses on the fuel economy and exhaust emissions at variations of air intake pressure. The air intake pressure is influenced by the degree of opening throttle plate and venturi effect which draw the fuel to the combustion chamber in carbureted engine. The experimental work is conducted...
