Method for lubricating at least two units of a vehicle equipped with an internal combustion engine

A method for lubricating at least two units of a vehicle having an internal combustion engine, each unit comprising one or more assemblies, the method comprising:

• successively conveying lubricant through the at least two units in that fresh lubricant is fed to a first unit of the at least two units from a container, at least some of the used lubricant is removed from an oil trough of the individual units and is fed to the unit which is respectively arranged afterwards in the series;
• and
• feeding the lubricant which is removed from the oil trough of the last unit to the internal combustion engine for combustion,
• wherein additives are added to the lubricant removed from the unit, before it is fed to the unit which follows in the series.

A method for lubricating at least two units of a vehicle having an internal combustion engine, each unit comprising one or more assemblies, the method comprising:

• successively conveying lubricant through the at least two units in that fresh lubricant is fed to a first unit of the at least two units from a container, at least some of the used lubricant is removed from an oil trough of the individual units and is fed to the unit which is respectively arranged afterwards in the series;
• and
• feeding the lubricant which is removed from the oil trough of the last unit to the internal combustion engine for combustion,
• wherein the lubricant which is removed from the oil trough of the last unit is fed, or sprayed, for the purposes of combustion, into the exhaust section of the engine.

A vehicle having an internal combustion engine, having a reservoir container for fresh lubricant, the vehicle comprising:

• at least two units to be lubricated by lubricant successively conveyed through the at least two units, each unit comprising one or more assemblies and having an oil trough, and
• a fuel tank and a fuel line for feeding fuel into the internal combustion engine,
• wherein the at least two units are arranged in series in such a way that a feed line for fresh lubricant leads from the reservoir container to a first unit in a series, in each case a lubricant line leads from a unit which is arranged in a preceding position in the series, to a unit which is arranged afterwards in the series, and a discharge line for used lubricant leads into the fuel line or an exhaust section of the internal combustion engine from the unit which is last in the series,
• wherein the first unit to which lubricant is fed comprises one or more assemblies from the group consisting of hydraulics, transmission, and wet brakes, and
• wherein each consecutive unit comprises at least one assembly being lubricated by the lubricant conveyed from an oil trough of a preceding unit.
