ABSTRACT:
A reciprocating piston internal combustion engine having an intake air system, an exhaust gas system, and an injection pump. To lubricate the injection pump, the latter can communicate with the lubricating-oil system of the internal combustion engine; the injection pump conveys a fuel having a low boiling point. A vaporizer is provided, the input side of which can communicate with the lubricating-oil return line of the injection pump, and the output side of which can communicate with the lubricating-oil system of the internal combustion engine and with the intake air system. The vaporizer serves for purifying the lubricating oil of fuel constituents which have a low boiling point and which contaminated the lubricating oil as a result of unavoidable leakages within the injection pump.
