ABSTRACT:
A two cycle, crankcase compression having fuel injection controlled in response to sensed intake air flow. The intake air flow is measured by measuring the crankcase pressure at crank angles corresponding to scavenge port opening and scavenge port closing of the engine. However, the actual angle at which the pressure is measured is adjusted to compensate for delay in the sensor reading and variations in the electric power supplied to the sensor. In addition, an arrangement is shown for protecting the sensor from corrosion.
