What does it mean when the engine overspeed warning appears?
1 Answers
Prompting engine overspeed occurs when the accelerator is pressed too deeply, causing the engine speed to rise excessively and exceed the prescribed limit. Excessive speed can significantly impact the engine. Below is relevant information: 1. Engine block: The block serves as the framework of the engine, providing the installation base for all engine mechanisms and systems. It houses all major components and accessories, bearing various loads. Therefore, the block must possess sufficient strength and rigidity. The block assembly mainly consists of the cylinder block, cylinder liner, cylinder head, and cylinder gasket. 2. Common fault causes: Throttle position sensor malfunction, excessive fuel pressure, cold start injector leakage or cold start control malfunction, injector leakage, oxygen sensor failure, ignition system failure.
