ABSTRACT:
A particular cooling water passage structure is installed in a V-type engine having two cylinder banks offset in a lengthwise direction of a crankshaft. Each bank is provided with inlet ports, provided to admit a cooling water flow. Each inlet port communicates with a lengthwise front end portion of the water jacket. The inlet port of one of the cylinder banks, which is offset forward relative to the other, is further in communication with a side portion, adjacent to the front end portion, of the water jacket. The inlet ports have apertures which open at the same location in the lengthwise direction. Piping, connected to the inlet ports, is provided in a space formed between the offset cylinder banks.
