What is the optimal RPM for starting an engine?

[JanelleAnn]

When starting an engine on normal road conditions, it is appropriate to begin at around 1200 RPM. For climbing hills or when the vehicle is under heavy load, the RPM can be appropriately increased. Important notes: In winter, it is best to warm up the engine for about a minute before starting, and the starting RPM should not exceed 2000, as higher RPMs can be harmful to the engine. Relevant information about engine RPM is as follows: 1. The engine RPM is related to the number of work cycles per unit time or the effective power of the engine, meaning the effective power of the engine varies with different RPMs. 2. The effective power specified on the engine's product label and its corresponding RPM are referred to as the rated power and rated RPM, respectively. The operating condition of the engine at the rated power and rated RPM is called the rated condition.
