Abstract
An improved fuel delivery system which combines the advantages of an ultrasonic spray with fluidic metering of fuel. A fuel delivery system is provided which includes a plurality of fluidic controls each of which is responsive to a particular engine condition. The fluidic controls are disposed in fluidic branches to meter fuel flow in response to each engine operating conditions. The fluidic devices are preferably configured in four branches to respond to choke (start), idle, acceleration and cruise conditions to meter fuel to an ultrasonic atomizing spray device.
Claims8
A fuel supply system for an internal combustion engine comprising;
- a fuel tank;
- a carburetor;
- a plurality of fluidic control means having inlets and a plurality of outlets, said plurality of outlets supplying fuel from said tank to said carburetor in said engine;
- said fluidic control means including at least a separate fluidic control for starting, idling, accelerating, and cruising conditions respectively;
- pump means pumping fuel from said fuel tank to said fluidic control means;
- said pump means including constant pressure fluidic control means;
- ultrasonic spray means in said carburetor connected to receive fuel from said plurality of fluidic control means and discharge the fuel into said engine;
- responsive means responsive to an engine condition connected to a control line in each of said plurality of fluidic control means;
- whereby each of said fluidic control means responds to an engine condition being monitored by said responsive means to increase or decrease fuel supply at constant pressure to said ultrasonic spray means.
