What is the RPM when a new car is just started?
2 Answers
The RPM when a new car is just started is around 1000. Here is some information about the RPM when a new car is just started: 1. Engine: At the moment of engine start-up, the RPM is approximately around 1000. The resistance during start-up varies depending on the technical condition of the engine. A new engine that hasn't undergone proper break-in has relatively "tighter" fits between moving parts, resulting in greater start-up resistance. 2. RPM difference: Drivers can hardly distinguish the RPM difference between a new car and a well-broken-in car during start-up, as the gap is small unless precise measurements are taken. The starting performance of a car engine is evaluated based on the start-up time. If it can start successfully within 5 seconds, it is considered to have good starting performance.
When I start my new car, the engine speed is usually around 1200 to 1500 RPM because the engine is cold, and the computer automatically increases the speed to quickly heat up the catalytic converter and reduce emissions. After driving for a while, it drops below 800 RPM and stabilizes. Different car models may have slightly different speeds, such as SUVs or turbocharged models which might be higher, while smaller cars are lower. I remember that with a new car, you should avoid revving the engine hard when it's cold; wait for the speed to drop before driving off, as this protects the engine's lubrication system and extends its lifespan. In northern winters, the starting speed is higher, while in summer it's lower—this is normal, so no need to worry. Regular maintenance checks on the engine oil and cooling system are essential, and if the RPM fluctuates too erratically, it's time to visit the 4S shop.
