Why is the car loud when starting?
1 Answers
It is normal for a car to be loud when starting. During a cold start, the engine oil pressure takes time to build up, resulting in poorer lubrication and thus louder noise. Additionally, after a cold start, the engine runs at a higher idle speed to reach the optimal operating temperature quickly, which may make the noise seem louder. The noise will gradually decrease as the idle speed drops until it disappears. Here is some related information about idle speed: 1. Introduction: Idle speed is an operating condition of a car where the engine runs in neutral gear. The engine speed during idle is called the idle speed, which can be adjusted by modifying the throttle opening. Idle speed means the engine is "working but not producing output." 2. Driving idle: When the car is in gear without pressing the accelerator pedal or when the accelerator pedal is released while driving, maintaining the minimum throttle opening, the engine speed matches the parking idle speed. This state is referred to as driving idle.
