Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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. 2. The internal combustion engine according to claim 1 , wherein the first cooling water passage includes a lower stage cooling water passage that is provided adjacent to a combustion chamber defined by upper portions of the cylinder bores and a lower portion of the cylinder head, and an upper stage cooling water passage that is communicated with the lower stage cooling water passage and provided above the lower stage cooling water passage, and the first cooling water introducing part is configured to lead cooling water, which is flown out from the upper stage cooling water passage and the lower stage cooling water passage, to the heat exchanger. 3. The internal combustion engine according to claim 1 , wherein the heat exchanger is a radiator that has a tube through which cooling water flows, and the heat exchanger is configured to exchange heat between a coolant and the cooling water.
