Title:
COOLING DEVICE FOR INTERNAL COMBUSION ENGINE, AND METHOD FOR CONTROLLING SAME
Document Type and Number:
WIPO Patent Application WO/2014/080778
Kind Code:
A1
Abstract:
A cooling device is provided with a head cooling flow passage (13), a block cooling flow passage (14), and oil heat exchangers (20, 21). The head cooling flow passage cools a cylinder head (11) by means of cooling water which flows through the head cooling flow passage. The block cooling flow passage cools a cylinder block (12) by means of cooling water which flows through the block cooling flow passage. The oil heat exchangers exchange heat between lubricating oil in a power train and the cooling water which flows through the head cooling flow passage and the block cooling flow passage. The cooling device raises both the temperature of the cooling water which flows through the head cooling flow passage and the temperature of the cooling water which flows through the block cooling flow passage to the same temperature and then, before reducing the temperature (WB) of the cooling water which flows through the block cooling flow passage, reduces the temperature (WH) of the cooling water which flows through the head cooling flow passage.
