Abstract
A multi-cylinder engine includes a plurality of combustion chambers and employs an improved intake pressure sensor arrangement to control fuel injection into the combustion chambers. A plurality of intake conduits define intake passages through which air flows to the combustion chambers. An intake pressure sensor senses intake pressure within the intake passages. A plurality of first conduits are coupled with an accumulator independent of one another and a second conduit is also coupled with the accumulator. The first conduits connect the accumulator to the respective intake passages. The second conduit connects the accumulator to the intake pressure sensor. A control device controls the amount of fuel injected into the combustion chambers based upon at least a signal from the intake pressure sensor.
