    • A fuel atomizer adaptable for use in cold starting a spark-ignited engine such as a single-cylinder motorcycle engine, especially when fueled by a low volatility fuel such as ethanol. The fuel atomizer comprises a nozzle (26) mounted in an engine air intake manifold (28), a pneumatic air tank (12), and an electrically-operated valve for dispensing air and fuel through the nozzle into the manifold. The air tank is filled by an air pump driven by the engine during periods of engine operation. The nozzle is preferably positioned such that atomized fuel is immediately mixed with air in the manifold. An engine control module monitors the fuel load being supplied to the engine at all times and varies the output of both the fuel atomizer and the individual fuel injectors in a smooth, fuel-efficient, start-up/warm-up protocol.
    • 一种燃料雾化器,适用于冷启动火花点火发动机,如单缸摩托车发动机,特别是当由低挥发性燃料如乙醇燃料时。 燃料雾化器包括安装在发动机进气歧管(28)中的喷嘴(26),气动空气罐(12)和用于通过喷嘴将空气和燃料分配到歧管中的电动阀。 发动机运转期间,空气罐由发动机驱动的气泵填充。 喷嘴优选地定位成使得雾化的燃料立即与歧管中的空气混合。 发动机控制模块一直监视供应给发动机的燃料负荷,并以平稳,省油的启动/预热方案改变燃料雾化器和各个燃料喷射器的输出。
