As a mechanical engineer with a focus on automotive systems, I have a deep understanding of the intricacies of engine operations. Let's delve into the concept of an engine seizure.
An engine seizure is a critical mechanical failure within an internal combustion engine. It occurs when the moving parts of the engine become so tightly bound together that they can no longer move freely. This binding is typically due to excessive heat and friction, which can be caused by a variety of factors, but the most common and definitive cause is indeed a lack of lubrication.
In a properly functioning engine, oil plays a pivotal role in reducing friction between moving parts. It acts as a medium that allows components such as pistons, bearings, and crankshafts to move smoothly against one another. When oil is present, it forms a thin film that separates these parts and prevents direct metal-to-metal contact. This not only reduces wear and tear but also helps in heat dissipation.
However, if the engine is not adequately lubricated, the moving parts can start to rub against each other with full force. This friction generates heat, which in turn causes the metal parts to expand. As the temperature rises, the oil can break down and lose its viscosity, which further exacerbates the situation. The metal parts can seize, or lock up, preventing the engine from turning and potentially leading to catastrophic damage.
The signs of an impending engine seizure can be quite telling. One of the most noticeable symptoms is a drop in power. As the engine struggles to move its components due to the lack of lubrication, it will not be able to generate the same amount of power as it normally would. This can manifest as a loss of acceleration or a general feeling of sluggishness when driving.
Other symptoms may include unusual noises such as knocking, pinging, or grinding, which can be indicative of metal parts striking against each other. Additionally, the engine may run hotter than usual, which can be detected by a higher than normal temperature reading on the dashboard gauge.
In some cases, there may also be visible signs of oil leakage or a burning smell, which can be a result of oil not reaching the necessary parts due to a blocked or leaking oil system.
Preventing engine seizure is largely about regular maintenance and monitoring. It's essential to check the oil levels regularly and to change the oil and oil filter at the manufacturer's recommended intervals. Using the correct type of oil for the engine and ensuring that the cooling system is functioning properly are also critical in preventing overheating and the subsequent risk of seizure.
In conclusion, an engine seizure is a serious condition that can lead to significant engine damage and costly repairs. It is primarily caused by a lack of lubrication, leading to excessive heat and friction. By being vigilant about engine maintenance and addressing any issues promptly, the risk of engine seizure can be greatly reduced.

The correct answer is A. Correct. Engine seizure is caused by a lack of lubrication. Without oil, the engine's moving parts can't move smoothly against each other and the engine will overheat. The strongest signal that an engine is about to seize is that the power drops.
