内燃機関に用いられている潤滑油の温度に対する耐久性を試験するにあたり、 その潤滑油の温度を上昇するには、従来では、液冷式内燃機関であるとき、その 冷却液の温度を上昇している。このような先行技術では、内燃機関の耐熱上の問 題により、冷却液の温度を100℃以上に上昇することができず、したがって潤 滑油の温度をあまり上昇することはできない。また季節によって冷却液の温度が 変動し、潤滑油の温度を希望する値に安定に保つことは困難である。 When testing the durability of a lubricating oil used in an internal combustion engine against temperature, the conventional method for raising the temperature of the lubricating oil is to increase the temperature of the cooling fluid in the case of a liquid-cooled internal combustion engine. ing. In such a prior art, the temperature of the cooling liquid cannot be raised to 100 ° C. or higher due to the heat resistance problem of the internal combustion engine, and therefore the temperature of the lubricating oil cannot be raised so much. In addition, the temperature of the cooling fluid fluctuates depending on the season, and it is difficult to keep the lubricating oil temperature stable at the desired value.

Although such a prior art can be applied to a very small internal combustion engine such as for an automobile, in a large internal combustion engine such as an internal combustion engine for cogeneration, the lubricating oil is uniformly heated to a desired temperature. It is difficult to heat and is not actually done.
