INTERNAL COMBUSTION ENGINE

摘要

An internal combustion engine includes: a cylinder block having a block cooling water passage that supplies cooling water to a plurality of cylinder bores, and an inter-bore cooling water passage provided between cylinder bores that supplies cooling water between the cylinder bores; a cylinder head having a first cooling water passage to which cooling water is supplied from the block cooling water passage, and a second cooling water passage, which is provided independently from the first cooling water passage, and to which cooling water is supplied from the inter-bore cooling water passage; a heat exchanger; a first cooling water introducing part that leads cooling water, which is flown out from the first cooling water passage, to the heat exchanger; and a second cooling water introducing part that leads cooling water, which is flown out from the second cooling water passage, to a downstream side of the heat exchanger.

1. An internal combustion engine comprising:
a cylinder block having a block cooling water passage configured to supply cooling water to a plurality of cylinder bores, and an inter-bore cooling water passage provided between cylinder bores, the inter-bore cooling water passage being configured to supply cooling water between the cylinder bores; a cylinder head having a first cooling water passage to which cooling water is supplied from the block cooling water passage, and a second cooling water passage, the second cooling water passage being provided independently from the first cooling water passage, and the second cooling water passage being configured such that cooling water is supplied from the inter-bore cooling water passage to the second cooling water passage; a heat exchanger; a first cooling water introducing part configured to lead cooling water, which is flown out from the first cooling water passage, to the heat exchanger; and a second cooling water introducing part configured to lead cooling water, which is flown out from the second cooling water passage, to a downstream side of the heat exchanger.
