【 摘 要 】

Fossil fuel used by many car. Reduce fuel usage make a big change to our environment. Water Methanol Injection system injected water and methanol mixture into combustion chamber of an engine. In fact methanol has high octane number and water has characteristic that delay the combustion also cooling effect for combustion chamber. Then injecting premixed water and methanol beside the fuel will produce higher power and more fuel efficiency. The aim of this study was to increase fuel efficiency for a greener engine with the same engine model because the system can be mounted into any engine and just tune it properly. Injection method required system that able to control pressure, and flow rate to keep it efficient while working. Previous research found optimum range ratio is 10-25% premixed water methanol to fuel. To make the system meets the injection ratio target it must be connected with the Engine Control Unit that tells amount of fuel required. The research used an electronic fuel injection K24Z Honda engine.
