ABSTRACT:
An air-cooled multi-cylinder engine including two temperature sensors each attached to different cylinders. The temperature difference between the two cylinders is detected by the temperature sensors. The air-fuel ratio in each cylinder is made the stoichiometric air-fuel ratio by decreasing the amount of fuel fed into higher temperature cylinders and increasing the amount of fuel fed into lower temperature cylinders.
