What Causes Engine Cylinder Cracking?
1 Answers
Engine block cracking can be caused by the following reasons. Lack of coolant in the radiator: If only water is added to the radiator without antifreeze, the water inside the engine block may freeze when the outside temperature is too low, causing the block to crack. Additionally, if the engine overheats and too much cold water is added directly or poured onto the engine, the sudden cooling can cause thermal shock, leading to cracks in the engine block. During severe impacts, the engine block may also develop cracks. The engine block is the most critical component of a car engine, providing installation and support for various engine parts, ensuring the accurate positioning of moving components such as pistons, connecting rods, and crankshafts, and facilitating engine ventilation, cooling, and lubrication. Water entering the engine cylinders: This can cause the connecting rods to break. When a vehicle drives through flooded roads, water may be sucked into the cylinders. Initially, the water entering the cylinders quickly turns into steam due to the high temperature, preventing the formation of a combustible air-fuel mixture. As more water enters, it accumulates on top of the pistons, reducing the effective volume of the combustion chamber and increasing compression resistance, which in turn increases the pressure transmitted to the connecting rods. When the water volume reaches a certain level, the compression stroke essentially compresses the water, drastically increasing the pressure on the connecting rods, leading to bending, deformation, or even breakage, and potentially damaging the engine block.
