Abstract：IA single-cylinder four-stroke single spark plug gasoline engine for the China Econopower Race . The driving standard is determined by the most distance per liter of oil, reducing fuel consumption as the ultimate goal. But the engine＇s fuel economy driving distance of the vehicle played a vital role. Better fuel economy can reduce the fuel consumption of vehicle, increasing driving range. Dual spark plug is a measure which can significantly improved fuel economy. We devise the dual spark plug ignition system and optimize the ignition advance angle legitimately, making the engine work at the best advance angle. Then the comparison test of engine performance is conducted on the base of the work above. Bench test show that: at the same experimental conditions in the premise, compared with single spark plug, dual spark plugs and optimizing ignition advance angle legitimately can improve the engine＇s fuel economy, reduce vehicle fuel consumption and improve the car performance competition
