Abstract:
A multicylinder engine cooling apparatus includes: an exhaust side cooing passage individually formed to extend in an exhaust side of the cylinder head in which the plurality of exhaust pipes are disposed; an intake side cooling passage individually formed to extend in an intake side of the cylinder head in which the plurality of intake pipes are disposed; a first downstream cooling water passage through which the cooling water having passed through the exhaust side cooling passage flows; a second downstream cooling water passage that allows the cooling water having passed through the exhaust side cooling passage and then the intake side cooling passage to flow to the first downstream cooling water passage at some midpoint of the first downstream cooling water passage; and a switching valve that switches a flow passage of the cooling water discharged from the exhaust side cooling passage between the intake side cooling passage and the first downstream cooling water passage.
