1. An air-cooled multi-cylinder engine having a plurality of cylinders arranged along a direction of flow of a cooling air, said engine comprising:
- temperature sensors attached to at least two cylinders to detect a temperature difference between said two cylinders andair-fuel ratio control means for controlling an air-fuel ratio of in each cylinder on the basis of said temperature difference to make the air-fuel ratio in each cylinder a target air-fuel ratio.

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.

14. An air-cooled multi-cylinder engine having a plurality of cylinders which are arranged along a direction of flow of a cooling air, said engine comprising:
-
detecting means for detecting an amount of cooling air flowing around the cylinders; estimating means for estimating a temperature difference between two cylinders on the basis of said amount of the cooling air; and air-fuel ratio control means for controlling an air-fuel ratio in each cylinder on the basis of said temperature difference to make the air-fuel ratio in each cylinder a target air-fuel ratio. - View Dependent Claims (15, 16, 17, 18, 19, 20)
