What are the symptoms of water entering a diesel engine?

[DeGiselle]

Possible symptoms of water entering the engine cylinder block include cracks in the cylinder liner, water spraying from the radiator, white smoke emitting from the exhaust pipe when the engine is running, reduced power output, and in severe cases, failure to start. Below is relevant information about the engine cylinder block: 1. The engine consists of two main parts: the cylinder block and the cylinder head, which are connected to each other by bolts. 2. The cylinder block material should have sufficient strength, good casting and machining properties, and be low-cost. Therefore, commonly used materials for cylinder blocks are cast iron and alloy cast iron. However, aluminum alloy cylinder blocks are becoming increasingly popular because they are lightweight, have excellent thermal conductivity, allow for reduced coolant capacity, quickly reach operating temperature after startup, and have the same thermal expansion coefficient as aluminum pistons. This results in minimal clearance changes when heated, reducing impact noise and oil consumption. Additionally, aluminum alloy cylinder blocks have the same thermal expansion as aluminum alloy cylinder heads, which helps reduce thermal stress caused by thermal shocks during operation.
