METHOD OF DIESEL LOCOMOTIVE DIESEL ENGINE COOLING SYSTEM AUTOMATIC INDEPENDENT WARMING-UP Russian patent published in 2017 - IPC B61C5/00 F01P11/20 

FIELD: warming-up.

SUBSTANCE: invention relates to diesel locomotive diesel engine warming-up. Method of diesel locomotive diesel engine cooling system automatic independent warming-up includes, that warmed-up diesel engine is periodically started, performing diesel engine and its cooling system heating. Diesel engine shutdown occurs automatically at diesel engine cooling system component preset operating temperature, having most heat capacity. Automatic diesel engine starting occurs at cooling system component with highest heat capacity temperature drop to specified value or temperature drop below permissible limit in cooling system component with minimum heat capacity. After diesel engine shutdown performing coolant pumping through the entire diesel locomotive cooling system. Pumping is actuated at temperature drop in cooling system component with minimum heat capacity to threshold value, exceeding permissible limit for diesel engine starting. Pumping is switched off when temperature in cooling system component with minimum heat capacity reaches set limit.

EFFECT: technical result consists in reduction of pump operation duration for coolant pumping in cooling system and storage battery increased service life.
