1. An internal combustion engine comprising:
two intake pipe portions configured to guide intake air to two banks;
a blow-by gas recirculation path configured to guide blow-by gas from a cylinder head including the two banks or from a crankcase to the two intake pipe portions;
a silencer connected to upstream sides of the two intake pipe portions and configured to suppress intake noise; and
a branch unit provided on a downstream side of the silencer and configured to allow intake air in which the intake noise is suppressed to branch to flow into the two intake pipe portions,
wherein the blow-by gas recirculation path includes a distribution passage provided between the two intake pipe portions on the downstream side of the silencer and configured to allow the blow-by gas to be distributed to flow into the two intake pipe portions.
