Which Parts Does Engine Oil Lubricate in a Car?
2 Answers
Engine oil lubricates the following parts in a car: 1. Valve train. 2. Crankshaft bearings. 3. Pistons. 4. Engine crankshaft chamber. 5. Gasoline engine pistons. 6. Hydraulic lifters and hydraulic tappets. Engine oil, also known as motor lubricant, serves multiple functions including lubrication and friction reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption and cushioning for the engine. Symptoms of insufficient engine oil in a car include: 1. Insufficient lubrication in parts requiring lubrication due to oil splashing inside the engine. 2. Bearing seizure between the crankshaft bearings and bearing shells caused by poor lubrication. 3. Abnormal engine vibration and reduced power output. 4. Malfunctioning of the engine's variable timing solenoid valve.
When I first started driving, I knew nothing about car maintenance. It wasn't until one day when the engine noise was as loud as thunder that I took it for inspection and found the engine oil was almost dry. Engine oil primarily lubricates the moving parts inside the engine, such as the pistons moving up and down in the cylinders, the crankshaft rotating, and those bearings and camshafts. When these parts rub against each other at high speeds, they generate heat. The oil is applied to reduce wear and prevent seizing. Later, the mechanic told me that neglecting oil changes would accelerate part wear and could even lead to engine failure, requiring expensive repairs. Now I've learned my lesson. I check the oil level and color by opening the hood every month and change it regularly. This not only extends the car's lifespan but also saves me a lot of hassle and money.
