Engine Fuel System
The fuel injection system is all-electronic and is microprocessor controlled. It can continually
compensate for variations in engine load, speed and temperature to give the best economy and power.
The most unique feature of the system is the air mass meter which measures the mass of the inducted air
instead of the volume. In this way the system can make instantaneous adjustments for changes in air
temperature or density, thus always assuring the best economy with the lowest possible exhaust
emissions.
