Engine Improvement Presented by: MuhamadArifFadli Ahmad
Injection System • Fuel efficiency increase • The air-fuel ration can be adjusted to save fuel • The timing of the introduction of the fuel into the combustion chamber can be manipulated • No need for choke during cold start
Increased Pressure • Increase pressure in the combustion chamber • Can be achieved be putting a turbine or simple rotating fan
Air Filter Open pod air filter allows better air flow to the engine, increasing the performance
Invasive Modification MAINJET CHANGES • Increase fuel-air ratio needed for alcohol • Enlarge this opening by anywhere from 20 to 40% IDLE ORIFICE CHANGES (Carburator) • For the engine to run at slowest, or idle, speeds, the air-fuel mixture will pass thru the idle orifice • If it isn't large enough, will not provide the needed amount of air/fuel blend to keep the engine running • May only be necessary to loosen the idle mixture screw at the base of the carburetor • Can be enlarged by 50% ENGINE TIMING • The correct timing advance for a given engine speed will allow for maximum cylinder pressure to be achieved at the correct crankshaft angular position
