Patent attributes
In detection of a temperature of fresh air which is supplied to an intake manifold of an engine, by a fresh air temperature sensor, the invention aims at preventing precision of an engine control from dropping due to difference in an attached position of the fresh air temperature sensor. The engine device has an intake pipe for supplying fresh air to the intake manifold, a breather chamber for separating lubricating oil, the breather chamber being arranged within a head cover covering an upper surface side of a cylinder head, and a blow-by gas return pipe. The intake pipe and the breather chamber are connected via the blow-by gas return pipe. The fresh air temperature sensor detecting a temperature of the fresh air introduced into the intake pipe is attached to the intake pipe.
