Abstract: Systems and methods are provided for an engine. The system comprises a direct injection engine having a cylinder in which a piston is slidingly supported to form in combination with a cylinder head a combustion chamber; a fuel injector for the cylinder having a catalytic coated tip portion that projects into the combustion chamber; and an electronic controller to control the operation of the engine and operates the engine in a heating mode of operation if heating of the fuel injector tip is requested. Various methods for heating the fuel injector tip are proposed including operating the engine on a reduced number of cylinders and varying one or both of fuel injection timing and quantity of fuel injected and the ignition timing in order to increase the temperature of combustion.

Abstract: Approaches for controlling dwell time in the ignition system of an internal combustion engine are provided. In one example, a method may include adjusting dwell based on engine operating conditions and further adjusting dwell in a manner proportional to existent spark plug conditions. By constantly assessing spark plug condition during operating of the internal combustion engine, premature wear of the spark plug may be prevented leading to an extension in the service life of spark plug and other ignition system components.
