Abstract
A method and a device for the lubrication, and for the simultaneous fuel supply, of an internal combustion engine are described. To an internal combustion engine during its continuous operation an additive-treated vegetable oil is supplied as a lubricant. The used vegetable oil lubricant, together with a mixture of fresh vegetable oil and Diesel oil or rape seed oil methyl ester is combusted in doses in the engine as engine fuel.

A method for lubrication of and simultaneous supply of fuel to an internal combustion engine, comprising:
- removing a first portion of fresh vegetable oil from a first container;
- mixing said first portion of fresh vegetable oil with an additive supplied from a second container to thereby provide an additive-treated vegetable oil;
- supplying to an internal combustion engine as a lubricant said additive-treated vegetable oil;
- removing a second portion of said fresh vegetable oil form said first container;
- and combusting in said internal combustion engine a fuel including a mixture of said additive-treated vegetable oil that is discharged from an oil pan of said internal combustion engine via an oil line as used additive-treated vegetable oil, said second portion of said fresh vegetable oil, and one of Diesel oil and rape seed methyl ester supplied from a fuel tank.
