METHODS FOR VARNISH REMOVAL AND PREVENTION IN AN INTERNAL COMBUSTION ENGINE |
摘要 |
<p>Methods for removing and preventing the buildup of unwanted deposits and varnishes on combustion chamber surfaces, particularly injector-igniter components that are exposed to combustion events. A method of removing deposits from an injector-igniter comprises monitoring the current across a pair of electrodes in the injector-igniter, comparing the current with a predetermined threshold level, and performing a cleaning cycle if the current exceeds the threshold level. The cleaning cycle may comprise injecting oxidant through the injector-igniter and into the combustion chamber. The cleaning cycle may further comprise ionizing the oxidant with an electrical discharge having a first polarity and ionizing the oxidant a second time with an electrical discharge having a second polarity. In other cases the cleaning cycle comprises injecting hydrogen through the injector-igniter and into the combustion chamber. In still other cases the cleaning cycle may comprise injecting coolant onto the electrodes.</p> |
