Abstract
In a cooling mechanism for an engine electronic control module, a base plate of the engine electronic control module is attached to an intake pipe, and includes air rectifier fins. The air rectifier fins have an air rectification function for concentrating suction-air streams at a position while rectifying the suction-air streams, and a cooling function for cooling the engine electronic control module. Suction air flows into an intake duct, in which an air flow meter is provided, through the air rectifier fins. Therefore, eddies of air can be restricted from being generated at an upstream side of the air flow meter, thereby obtaining stable air-flow signals from the air flow meter.
