    Abstract: A front and rear wheel drive vehicle having straddle-type seating. A power train is located beneath the seat and between the footpegs of the vehicle. The engine employs parallel output shafts located on either side of the crankshaft to drive power transmission means to the front and rear axles. A speed change mechanism is contained within the engine case along with the output shafts and includes a first transmission shaft between the crankshaft and one of the output shafts. In one embodiment, the cylinder block of the engine is illustrated as being inclined toward the speed change transmission such that the cylinder block, cylinder head and head cover do not extend laterally outwardly beyond the engine case. To employ both output shafts, sprockets are arranged on each shaft with a coupling chain. The orientation of the output shafts provides for a narrower engine profile.

  • Air fuel ratio control system for an internal combustion engine with improved operations for maintaining the engine output power
    Patent number: 4665883
    Abstract: An air/fuel ratio control system for an internal combustion engine provides a mixture leaner than a predetermined reference value when a detected engine load is in a light load range. In order to produce a required engine power during a transitional period, the system detects the speed of variation of an operating parameter used for the calculation of air/fuel ratio and controls the air/fuel ratio toward the reference level even though the magnitude of the detected engine load is in the light load range. Preferably, an EGR rate is also made smaller upon occurrence of a rapid change of the operating parameter so as to prevent the power down of the engine during the transitional period.
