摘要

The turbocharged internal combustion engine has a charge air cooler (11) connected to a turbocharger, and a charge air passage (16) to feed charge air from the compressor to the cooler. The charge air passage is cooled at least partially by means of cooling passages (17,18,19) through which flows cooling water. The charge air passage is at least partially double-walled in construction, whereby the cavity between the walls acts as the aforesaid cooling water passage.
