LOCOMOTIVE DIESEL ENGINE COOLING METHOD (VERSIONS) Russian patent published in 2003 - IPC

FIELD: railway transport. SUBSTANCE: invention relates to method of cooling diesel engines in diesel locomotives. According to proposed method, heat is removed in cooling chambers. In summer time part of water of air and oil cooler of diesel engine is cooled in diesel engine water cooling chamber. In winter time, at ambient temperature below zero (0^oC), all water of air cooler and oil cooler is cooled in diesel engine water cooling chamber. Of two cooling chamber for diesel engine water cooling are provided, all water of air cooler and oil cooler of diesel engine if cooled in turn in one of said chambers, while other chamber is switched off. EFFECT: increased efficiency, especially at low ambient temperatures. 3 cl, 5 dwg
