Abstract

The cleaning agent for a diesel engine includes a mixed solution obtained by blending a solvent that exhibits solubility and has an ignition point of 238° C. or more, and lubricating oil such as mineral oil in a predetermined ratio. The solvent and the grease are selected such that the cleaning agent has a higher ignition temperature characteristic than the ignition characteristic of light oil, and an evaporation characteristic that takes eight minutes or more to vaporize 2.5 cc of the cleaning agent in a heated state at 120° C.

Abstract

[Problem] To provide a cleaning agent that demonstrates high cleaning effect without producing knocking when the cleaning agent is drawn into a combustion chamber while the diesel engine is operating, and that has strong sustainability in cleaning effect; and to provide a technology related a diesel engine internal cleaning system that uses the cleaning agent. [Solution] An internal cleaning agent for diesel engine and cleaning system using same, the cleaning agent for the interior of a diesel engine and the cleaning system characterized in that: the cleaning agent is composed of a mixed liquid in which a solvent that demonstrates solubility and that has an ignition temperature of 238° or higher, and a lubricating oil such as mineral oil, are blended together in a predetermined ratio; and the oil and fat, and solvent are selected so as to have an ignition temperature characteristic that is higher than the ignition characteristic of light oil, and an evaporation characteristic in which eight minutes or more are required for 2.5 cc to evaporate in a state heated to 120° centigrade.
