Most small engine manufacturers are looking to introduce fuel control technology to reduce engine out emissions, however most available conventional fuel injectors consume high levels of power to achieve controlled injection and suitable atomisation of the fuel. Typical fuel injection pressures of 300kPa are required to achieve pulsed injection and up to 10MPa to achieve full atomisation. The addition of an extra air delivery system at pressures of 600kPa can also be employed to atomise the fuel. These methods require many 100's of Watt's of power making them unsuitable for the vast majority of small engine applications. This paper presents experimental data from a novel electrostatic atomiser designed specifically for application to small engines, with very low power requirements and excellent fuel atomisation.
