Abstract
The utility model relates to an engine oil cooling device which is mounted on an engine body. The engine oil cooling device comprises a cooling water cavity with a mounting flange. An engine oil cooler is connected to the mounting flange. The cooling water cavity is integrally arranged on the engine body. The cooler core of the engine oil cooler is disposed in the cooling water cavity. An engine oil filter is fixed on the body of the engine oil cooler. The body of the engine oil cooler is respectively provided with a filter oil inlet passage and a cooler core oil inlet passage. A bypass valve is connected between the filter oil inlet passage and the cooler core oil inlet passage. Due to the fact that the cooler core of the engine oil cooler is completely disposed in the cooling water cavity, cooling water cools the engine oil passing the engine oil cooler fast to lower the temperature of the engine oil. By the bypass valve, when an engine is just started, the high-pressure engine oil can avoid the cooler core oil inlet passage with large resistance, directly enter the filter oil inlet passage from the bypass valve, flows through a main oilway to lubricate each moving part, and moving part abrasion is lowered.
