ABSTRACT:
An internal combustion engine is disclosed which comprises first and second cylinder units each including at least one cylinder, pulse generator means for generating, in synchronism with engine rotation, a fuel injection pulse signal of pulse width proportional to the rate of air flow to said engine, and first and second fuel supply means responsive to the fuel injection pulse signal for supplying, into the first and second cylinder units, respectively, a controlled amount of fuel corresponding to the duty ratio of the fuel injection pulse signal. Control means is provided for cutting off the fuel injection pulse signal to the second fuel supply means when the engine load is below a reference level increasing with an increase in engine temperature except when the engine speed is below a given level at open throttle conditions.
