PCT No. PCT/DK96/00423 Sec. 371 Date Feb. 20, 1998 Sec. 102(e) Date Feb. 20, 1998 PCT Filed Oct. 7, 1996 PCT Pub. No. WO97/13968 PCT Pub. Date Apr. 17, 1997A multi-engine plant with a common freshwater cooling system comprises turbocharged diesel engines (1) which in their coolant system are provided with a charging air cooler 911), a high-temperature circuit (HT) and a low-temperature circuit (LT). The high-temperature circuit (4) contains a fist three-way circuit delivery pipe (7) to the engine with coolant. The low-temperature circuit (5) contains a second three-way valve (13) supplying coolant to the delivery pipe (14) of the charging air cooler in the LT circuit. The charging air cooler (11) is a two-step cooler in which the first step (10) is part of the HT circuit and the second step (19) is part o the LT circuit. A control valve (16) can adjust the coolant flow through the second step in dependency of the engine load. The discharge pipe (15) from the control valve is connected to the second three-way valve and a common return pipe (3). The discharge piper of the HT circuit from the engine is in flow communication with the common return pipe (3) and is connected to the first three-way valve, which is also connected to a common supply pipe (2).
