ABSTRACT:
A V-type internal combustion engine includes cylinder heads having respective compressed-air supply channels extending therein for providing fluid communication between an air compressor and charge injectors. Formation of condensation in the compressed-air supply channels is prevented. Charge injectors are provided in the respective cylinder heads, for directly injecting charges of fuel-air mixture into combustion chambers in cylinders. Compressed-air supply channels extend from an air compressor to the respective charge injectors, including a shared channel provided in a crankcase, and branched supply channels provided in each of the respective cylinder blocks. The compressed-air supply channels are internal conduits formed by attaching the cylinder blocks to the crankcase. In addition, cooling of the compressed air in the compressed-air supply channels is prevented during engine operation, so that formation of condensation within the compressed-air supply channels is prevented.
