Claims
- 1. An engine comprising an induction system including a plurality of intake passages, a plurality of fuel injectors, at least one of the fuel injectors communicating with a corresponding intake passage at an injection point within the corresponding intake passage, and a balance passage interconnecting together the plurality of intake passages, the balance passage communicating with each intake passage of said plurality of intake passages at the corresponding injection point within the intake passage, and a fuel supply system communicating with said fuel injectors, said fuel supply system including a pressure regulator which communicates with at least one of said intake passages at the corresponding injection point.
- 2. An engine as in claim 1, wherein said pressure regulator communicates with each intake passage through the balance passage.
- 3. An engine as in claim 1, wherein each intake passage communicates with a corresponding variable volume chamber of said engine through a check valve, and said balance passage communicates with each intake passage upstream of the check valve.
- 4. An induction system as in claim 1, additionally including a plenum chamber that communicates with each of said intake passages, said plenum chamber having a drain outlet that communicates with said balance passage.
- 5. An engine as in claim 1, wherein said fuel supply system additionally comprises a vapor separator having a vapor discharge port, and the vapor discharge port communicates with the balance passage to deliver fuel vapor to each intake passage.
- 6. An engine as in claim 5, wherein said induction system comprises a manifold in which said intake passages are formed, said manifold also defines said balance passage and supports said fuel injectors.
- 7. An engine as in claim 6, wherein said intake passages are vertically aligned above one another within said manifold.
- 8. An engine as in claim 7, wherein said vapor discharge port of said vapor separator communicates with said balance passage through a vapor passage formed in said manifold, and said vapor passage communicates with said balance passage at a point near an uppermost intake passage.
- 9. An engine as in claim 7, wherein said pressure regulator of said fuel supply system communicates with said balance passage through a pressure passage, and said pressure passage communicates with said balance passage at a point near an uppermost intake passage.
