度も高くなってきている。In recent years, internal combustion engines have tended to have higher output, and their operating pressures and operating temperatures have both become higher. Along with this, the operating temperatures of the lubricating oil system and fresh water cooling water system, which are the cooling systems of internal combustion engines, have also increased. It has become to.

However, in this case, there is a drawback that it takes a relatively long time to shift to high-load operation. In addition, if the transition time is shortened in such an internal combustion engine,
The problem arises of increased wear and tear on internal combustion engine components.

The auxiliary drive shaft (201) is connected to the compressor (4) via the clutch (202), and the clutch (202) is energized while the internal combustion engine Q51 is idling. 15) may directly drive the compressor (4). In this case,
In addition to warm-up from the fresh water cooling system, etc., the internal combustion engine generates more heat due to light load operation instead of idle link under no-load conditions, which further accelerates warm-up. This makes it possible to reduce machine time.
