Abstract
Keywords: Liquid Fuel, Atomization, Fuel Injection, Local Contact Microwave Heating
To control the atomization in the fuel injection, the Local-contact Microwaveheating method, a kind of the microwave heating technologies, was verified. The Localcontact Microwave-heating Injector (LMI) was manufactured with a commercial solenoid coil and a coaxial cable. The droplet dispersion area was used to evaluate the characteristics of the spray and an easy optics and a camera were used. The photographs were qualitatively evaluated with a simple image data processing. As a result, the droplet dispersion area was increased with the microwave heating. This shows that the LMI has a possibility to control the fuel atomization.
