What is the engine speed when starting the car?
2 Answers
The engine speed when starting the car is 1200 to 1500 revolutions per minute (RPM). RPM refers to the number of revolutions the engine crankshaft makes per minute. The engine speed affects the number of work cycles per unit time or the effective power output of the engine. Its function is to promptly reflect the operating condition of the engine, allowing the driver to better coordinate the transmission gear and throttle position, ensuring the car maintains optimal working conditions. Precautions when starting the car include: 1. Do not start the engine immediately after inserting the key; 2. For vehicles with a one-button start, do not press the brake pedal first when starting; 3. If the key fob for a one-button start vehicle is out of battery, bring the key close to the start button; 4. Do not use excessive force if the key cannot be turned after insertion.
I've driven many car models before, and the RPM at startup is usually between 1000 and 1500. This is especially noticeable during cold starts, particularly in winter when the RPM might be even higher. This is the engine computer automatically increasing the RPM to warm up the coolant faster, and after a minute or two, the RPM will drop to around 800 on its own. If the tachometer needle keeps fluctuating or stays above 2000 RPM after startup, then it's time to check for carbon buildup in the throttle body or sensor malfunctions. Using genuine engine oil is crucial for protecting the engine.
