Claims
- 1. In an engine combustion system having a plurality of combustion chambers, each combustion chamber having an intake valve, an exhaust valve and a fuel injector, the improvement comprising:
- a plurality of discrete, separate control modules each being connectable to a respective one of said intake valve, exhaust valve, and fuel injector of a respective engine cylinder and connectable to one another in fluid communication, each of said control modules having a housing having three actuator cavities, three valve cavities, a high pressure major passageway, a low pressure major passageway, three high pressure intake passageways, three high pressure delivery passageways, three low pressure intake passageways and three low pressure discharge passageways;
- each of said actuator cavities being adapted to receive a actuator in fluid communication with the respective valve cavity;
- each of said valve cavities adapted to receive an "on-off" valve;
- each of said high pressure intake passageways being in fluid communication with the high pressure major passageway and a respective valve cavity;
- each of said high pressure delivery passageways being in fluid communication with a respective valve cavity and, in the installed position, a respective one of the intake valve, exhaust valve and fuel injector;
- each of said low pressure intake passageways being in fluid communication with a respective one of the intake valve, exhaust valve, and fuel injector and with a respective valve cavity; and
- each of said low pressure discharge passageways being in fluid communication with a respective valve cavity and the low pressure major passageway.
- 2. An engine combustion system, as set forth in claim 1, wherein said actuator cavities and associated valve cavities are generally parallel to one another and transverse a longitudinal axis of said combustion chamber in the installed position.
- 3. An engine combustion system, as set forth in claim 1, wherein the housing is of unitary construction.
- 4. An engine combustion system, as set forth in claim 3, wherein the housing passageways and chambers are longitudinally straight and intersect one another at various angles.
- 5. An engine combustion system, as set forth in claim 1, wherein the housing passageways and chambers are formed by drilling.
- 6. In an engine combustion system having a plurality of combustion chambers, each combustion chamber having an intake valve, an exhaust valve and a fuel injector, the improvement comprising:
- a plurality of discrete, separate control modules each being connectible to a respective one of said intake valve, exhaust valve, and fuel injector of a respective engine cylinder and connectable to one another in fluid communication via a high pressure major passageway, each of said control modules having a housing having three actuator cavities, three valve cavities, three high pressure intake passageways, three high pressure delivery passageways;
- each of said actuator cavities being adapted to receive an actuator in communication with the respective valve cavity;
- each of said valve cavities adapted to receive an "on-off" valve;
- each of said high pressure intake passageways being in fluid communication with the high pressure major passageway and a respective valve cavity; and
- each of said high pressure delivery passageways being in fluid communication with a respective valve cavity and, in the installed position, a respective one of hte intake valve, exhaust valve and fuel injector.
- 7. An engine combustion system, as set forth in claim 6, wherein said actuator cavities and associated valve cavities are generally parallel to the other actuator cavities and associated valve cavities and traverse a longitudinal axis of said combustion chamber in the installed position.
- 8. The engine combustion system of claim 6, at least a portion of at least one of said high pressure delivery passageways being formed at a compound angle.
- 9. The engine combustion system of claim 2, wherein at least a portion of said passages are formed at a compound angle.
