What Sounds Are Normal for an Engine?
1 Answers
Engine idle sounds that are steady and without abnormal noises are normal. An engine is a machine that converts other forms of energy into mechanical energy. Below are the types of engines: 1. Internal combustion engine: Fuel burns inside the engine. 2. External combustion engine: Fuel burns outside the engine. 3. Gas turbine: Combustion produces high-pressure gas, which drives the turbine blades to rotate. 4. Jet engine: An engine that directly generates thrust through high-speed gas ejection from the nozzle. Below are the reasons why engine sounds may become louder: 1. Engine oil does not meet standards or is overfilled, increasing the stirring resistance of the crankshaft connecting rod. 2. Unsuitable oil viscosity. 3. Excessive engine carbon deposits, accelerating wear on cylinders and pistons. 4. Mixing different brands of engine oil. 5. Failing to change the engine oil on time.
