Abstract
The present invention provides, in an internal combustion engine of the type including: a combustion cylinder having a combustion chamber; an intake port in fluid communication with the combustion chamber; an intake valve for opening and closing the intake port; an exhaust port in fluid communication with the combustion chamber; and an exhaust valve for opening and closing the exhaust portion; the improvement comprising: (a) at least one intake injector disposed within the intake port for injecting a fluid into the combustion chamber; (b) at least one exhaust injector disposed within the exhaust port for injecting a fluid toward the exhaust valve; and (c) means for controlling the at least one intake injector and the at least one exhaust injector.
Claims21
In an internal combustion engine of the type including:
- a combustion cylinder having a combustion chamber;
- an intake port in fluid communication with the combustion chamber;
- an intake valve for opening and closing the intake port;
- an exhaust port in fluid communication with the combustion chamber;
- and an exhaust valve for opening and closing the exhaust port, the improvement comprising:
- (a) a plurality of intake injectors, each one of the plurality of intake injectors on a different axis and disposed within the intake port for injecting air into the combustion chamber;
- (b) a plurality of exhaust injectors for injecting air into the combustion chamber, each one of the plurality of exhaust injectors disposed within the exhaust port on a different axis;
- and
- (c) means for controlling the at least one intake injector and the at least one exhaust injector.
In an internal combustion engine of the type including a combustion cylinder having a combustion chamber;
- an intake port in fluid communication with the combustion chamber, an intake valve for opening and closing the intake port;
- an exhaust port in fluid communication with the combustion chamber;
- and an exhaust valve for opening and closing the exhaust port, the improvement comprising:
- (a) at least one intake injector disposed within the intake port for injecting air into the combustion chamber;
- (b) at least one exhaust injector disposed within the exhaust port for injecting air toward the exhaust valve;
- and
- (c) means for controlling the at least one intake injector and the at least one exhaust injector;
- (d) an intake air pump for providing the air to the at least one intake injector;
- (e) an exhaust air pump for providing the air to the at least one exhaust injector;
- and
- wherein the means for controlling the at least one intake injector and the at least one exhaust injector is an electronic computing system, the electronic computing system being in communication with the intake air pump, the at least one intake injector, the exhaust air pump, and the at least one exhaust injector.
In an internal combustion engine of the type including a combustion cylinder having a combustion chamber, an intake port in fluid communication with the combustion chamber, an intake valve for opening and closing the intake port;
- an exhaust port in fluid communication with the combustion chamber;
- and an exhaust valve for opening and closing the exhaust port, the improvement comprising:
