Abstract
In an internal combustion engine with cylinders and a crankshaft, coolant discharged from a coolant circulating pump is supplied to a coolant jacket formed in a cylinder block via a coolant jacket formed in a cylinder head. An inlet port through which the coolant discharged from the coolant circulating pump flows into the coolant jacket is provided at one end portion of the cylinder head on an intake side thereof in a cylinder-head center line direction, whereas an outlet port through which the coolant in the coolant jacket is allowed to flow out into a heater core is provided at the other end portion of the cylinder head on an exhaust side thereof.
Claims7
A water-cooled internal combustion engine with cylinders and a crankshaft, comprising:
- a cylinder block receiving said cylinders therein and defining a block-side coolant jacket;
- and
- a cylinder head connected to an upper portion of said cylinder block and defining a head-side coolant jacket,
- wherein coolant discharged from a coolant circulating pump is supplied to said block-side coolant jacket via said head-side coolant jacket,
- further wherein a first inlet port of said cylinder head through which said coolant discharged from said coolant circulating pump is allowed to flow into said head-side coolant jacket is provided at one end portion in a cylinder-head center line direction and an intake side of said cylinder head, and
- further wherein a first outlet port of said cylinder head through which said coolant from said head-side coolant jacket is allowed to flow out into a heater core is provided at the other end portion in the cylinder-head center line direction and an exhaust side of said cylinder head.
