Abstract
Each cylinder of a liquid cooled in-line internal combustion engine includes a cylinder pipe surrounded by an annular cooling chamber. The cooling chambers are interconnected in series by crossover passages between adjacent cylinder pipes and the cooling chambers have a greater cross sectional flow area on one side of the longitudinal central plane of the engine than on the other side. This cross sectional flow area relationship is reversed from cylinder to cylinder to thereby cause a meandering course of flow for a portion of the coolant thereby assuring adequate flow around the entire surface of the cylinder pipe and good flushing of the crossover passages between the cylinder pipes.
