Abstract

A method and apparatus for operating an internal combustion engine fuel injection system wherein fuel is cyclically injected directly into an engine combustion chamber through a selectively openable nozzle, whereby the nozzle is periodically maintained open while no fuel is being delivered through the nozzle and while the gas in the combustion chamber is at a temperature and pressure so that gas from the combustion chamber will pass into the open nozzle means to raise the temperature thereof sufficient to combust contaminate deposits thereon.
