Internal combustion engine, has low temperature cooler and charge air cooler arranged in low temperature circuit, where exhaust gas turbo charger is additionally arranged parallel to charge air cooler in low temperature circuit

摘要

The engine has a water cooling system with a lower temperature circuit (10), where a low temperature cooler (12) and a water-cooled charge air cooler (16) are arranged in the low temperature circuit. A water-cooled exhaust gas turbo charger (22) is additionally arranged parallel to the water-cooled charge air cooler in the low temperature circuit. An electrical cooling pump (14) is arranged in the lower temperature circuit, and the charge air cooler is designed as a plat heat exchanger.
