Controlling engine charge dilution for fuel efficiency |
摘要 |
Fuel consumption in a vehicle engine is reduced by varying charge dilution in an intake manifold of the engine to maintain a pressure in the intake manifold within a predetermined range. Pumping work performed by engine cylinders is reduced, which reduces fuel consumption.
