FIELD: machine building.
SUBSTANCE: invention relates to an engine lubrication system, in particular to lubrication of a high pressure fuel pump roller contact with a drive cam. Motor thermal motor comprises high-pressure fuel pump 12 and lubrication system 50. HPFP is located at engine lengthwise end facing engine connecting side (100). HPFP is actuated by a cam rigidly mounted on the engine crankshaft. Lubrication system includes oil inlet channel (21) formed in crankcase (10), channel (25) of HPFP lubrication, main longitudinal distributing oil line (20) orthogonal to both channels, and into which both channels extend. Inlet channel (21) is located parallel to connecting side (100) in continuation of lubricating channel (25). Nozzle (30) is arranged at the end of lubrication channel (25) to reduce oil consumption.
EFFECT: technical result consists in simple and reliable lubrication of the HPFP drive cams located on the end of the crankshaft.
