Abstract
A fuel system for a diesel engine having a plurality of combustion chambers, the engine having ignition cackle occurring in at least one combustion chamber includes a standard fuel injector being associated with each of the non-cackling combustion chambers, and a non-standard fuel injector being associated with each of the cackling combustion chambers, each of the non-standard fuel injectors having an increased pilot volume of fuel, the increased pilot volume of fuel having a quantity of fuel therein for injection into the associated combustion chamber. A non-standard fuel injector and a method for affecting cackle are also included.
Claims27
A method of affecting ignition cackle occurring in at least one combustion chamber of a diesel engine having a plurality of combustion chambers, the non-cackling combustion chambers having a standard fuel injector associated with each of such combustion chambers comprising the steps of:
- (a) identifying the combustion chamber experiencing the ignition cackle;
- and
- (b) increasing the pilot volume of fuel, the fuel in the increased volume for being provided to a fuel injector associated with the identified combustion chamber.
A fuel system for a diesel engine having a plurality of combustion chambers, the engine having ignition cackle occurring in at least one combustion chamber, comprising:
- (a) a standard fuel injector being associated with each of the non-cackling combustion chambers;
- and
- (b) a non-standard fuel injector being associated with each of the cackling combustion chambers, each of the non-standard fuel injectors having an increased pilot volume of fuel, the fuel in the increased volume for injection into the associated combustion chamber during a pilot portion of an injection event.
A non-standard fuel injector for use in a fuel system for a diesel engine, the diesel engine having a plurality of combustion chambers, a standard fuel injector being associated with each of at least some of the plurality of combustion chambers, the engine having ignition cackle occurring in at least one combustion chamber comprising:
- (a) the non-standard fuel injector being associated with each of the cackling combustion chambers, each of the non-standard fuel injectors having an increased pilot volume for fuel as compared to a pilot volume of fuel of a standard fuel injector, the increased pilot volume for containing a quantity of fuel for injection into the associated combustion chamber.
