Abstract
A method of injecting liquid fuel to an engine comprising delivering a quantity of fuel into a conduit and propelling the fuel along the conduit by a pulse of gas under sufficient pressure to discharge the fuel from an open nozzle into an engine induction passage, or combustion chamber. The pressure and quantity of gas preferably being suficient to cause the fuel to issue from the nozzle at or near sonic speed. The duration of the pulse of gas may be varied with the variation in the quantity of fuel to improve the fuel metering accuracy with engine load changes.
