| 摘要 |
<p>The invention relates to a method of operating a turbocharged piston engine (1), which comprises a low-temperature cooling circuit (13) for low-temperature cooling liquid, a high-temperature cooling circuit (19) for high-temperature cooling liquid, and a charge air cooler (12) connected to the low-temperature cooling circuit (13). In the method charge air is pressurised at least in one stage, the pressurised charge air is cooled by the charge air cooler (12) into which low- temperature cooling liquid is fed, a dew point of the pressurised charge air downstream of the charge air cooler (12) is defined, and temperature of the charge air leaving the charge air cooler (12) is adjusted to be higher than the dew point by controlling temperature of the low-temperature cooling liquid fed into the charge air cooler (12). The temperature of the low-temperature cooling liquid is controlled by adding high-temperature cooling liquid thereto.</p> |
