What Are the Effects of Leaving a Car Unused for a Year?
2 Answers
The effects of leaving a car unused for a year include battery depletion, flat tires, small animals nesting in the engine compartment, and fluid leaks. Below is an introduction to engine-related content: 1. Energy Conversion: An engine is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines typically convert chemical energy into mechanical energy. 2. Device: The term 'engine' can refer to both the power-generating device and the entire machine that includes the power unit (e.g., gasoline engines, aircraft engines). The engine was first developed in the UK, so the concept of the engine originates from English, with its original meaning referring to 'a mechanical device that generates power.'
My car was left unused for almost a year last year, and when I came back, it wouldn't start at all—the battery was completely dead because lead-acid batteries naturally discharge, resulting in voltage too low to ignite. The tires had deformed where they touched the ground, and the mechanic said prolonged inactivity can cause rubber to crack, increasing the risk of a blowout. Additionally, the engine oil had settled and clumped, affecting lubrication efficiency, so a full oil change was necessary. To make matters worse, I found spiderwebs and rodent-chewed wiring harnesses in the engine bay—small animals had gotten in and caused damage. To prevent these issues, it's recommended to start the engine at least once a month, even if you're not driving, and let it run for about 10–15 minutes to keep the systems active. For long-term parking, it's best to store the car in a dry place and disconnect the battery's negative terminal. These maintenance steps can save a lot on repair costs, especially for electronic components like remote keys, which gradually lose functionality.
