Claims

[Scope of utility model registration request]

A single-point fuel injector is installed in the intake passage downstream of the throttle valve location in the engine.
1. An injection fuel atomization device for an engine, characterized in that an air injection port is disposed near a fuel injection port of the injector to promote atomization of fuel injected from the injector.
