What Causes Sudden Increase in Engine Noise?
1 Answers
Possible causes include carbon buildup, improper engine oil grade selection, and cold starts at low temperatures. Below is relevant information about engine speed: Speed Measurement: Typically measured using a speed sensor that corresponds to signal teeth on the flywheel to determine engine speed. Speed Range: During idle, engine speed generally ranges between 700-1100r/min. Rated Condition: The operating state of an engine at its rated power and rated speed is called the rated condition. Rated power is not the maximum power an engine can produce, but rather the maximum usable limit of effective power determined by the engine's intended application. For the same engine model, the rated power value may vary depending on its specific application.
