Internal combustion engine with improved coolant arrangement
An internal combustion engine is described with a cylinder block having a line of cylinders and a cylinder head attached to a top surface of the cylinder block with a head gasket therebetween, longitudinally extending coolant distribution and discharge manifolds being provided adjacent each other on one side of the cylinder block, and coolant circuit means for circulating a liquid coolant from the distribution manifold through the cylinder head, from the cylinder head to coolant chamber surrounding each of the cylinders in the cylinder block and from the coolant chambers to the discharge manifold. The coolant circuit means comprises a row of intake passages connecting the distribution manifold with the interior of the cylinder head, each of the intake passages being located in association with a respective one of the cylinders on one side thereof, coolant flow paths through the cylinder head for directing coolant from the intake passages longitudinal and transversely through the cylinder head to outlet flow passages connecting the interior of the cylinder head with a top portion of coolant chambers surrounding each of the cylinders at a laterally opposite side of the cylinders from the side with the intake passages, and outlet openings connecting a bottom portion of the coolant chambers with the discharge manifold.
