A preparation for field tribological tests of lubricants and additives in a real diesel engine was carried out. A diesel generator based on a TMZ-450D singlecylinder air-cooled engine and its are described. In this connection, a specific task of the work is the study of the wear of parts in the cylinder-piston group of a complete diesel engine. In the statement of such a problem, a number of fundamental questions were solved regarding the compatibility of additive packages with the basic composition of lubricating oil and the final cost of the antiwear product added to the lubricating oil. The work demonstrates the specificity of the preparation for the tests and the technology of their implementation. Additionally, the technology of measuring parts in the cylinder-piston group, i.e. pistons, piston rings and cylinder lining. The study demonstrates the results of tribological field tests of lubricants tested in diesel engine TMZ-450D. The engine has a single-cylinder vertical layout and is designed for installation on light-duty vehicles, small-sized equipment, drives for mobile power plants, and as a stationary auxiliary marine engine. The implementation of the studied antiwear lubricant additive allowed reducing the overall wear rate of the cylinder-piston group of the diesel engine by 5-7%.
