  • System for operating two-cycle spark ignition engine
    Patent number: 5094196
    Abstract: A system for operating a two-cycle spark ignition engine, comprising an ultrasonic atomizer that is disposed in an intake pipe of the spark ignition engine. When the engine is to be started, a fuel for starting is supplied to the ultrasonic atomizer, and after the engine has been started, a gas oil is supplied to the ultrasonic atomizer to atomize and spray it into the intake pipe, thereby enabling an increase in the flow rate of fuel atomized and sprayed by the ultrasonic atomizer and realizing combustion of gas oil, and thus achieving a lowering in the fuel cost, ensuring safety and making it possible to provide a lightweight emergency pump unit which is suitable for use in vessels, for example.
