in daily useweb3wargameMany Vios owners may notice that during cold starts, the engine speed will be higher than the speed at normal operating temperatures. Whether this phenomenon falls within the normal range and what is the speed standard when starting a cold car are issues of concern to many car owners. This article will introduce in detail the relevant knowledge of cold car starting speed to help car owners better understand and judge their vehicle conditions.

Reason for the high starting speed of the cold car: When the cold car is started, the engine temperature is low, the oil viscosity is high, and the liquidity is poor, which will lead to increased friction inside the engine. In order to overcome this friction and quickly increase the engine temperature to working temperature, the vehicle's electronic control unit (ECU) automatically increases the idle speed of the engine. This not only speeds up the engine's heat engine process, but also reduces wear during cold start and protects the engine.

Standard for starting speed of cold cars: Generally speaking, the speed after starting cold cars will be higher than the speed at normal operating temperatures, usually between 1200 rpm and 1500 rpm. This range is the normal behavior of most vehicles during cold starts. As the engine temperature gradually increases, the speed will gradually decrease to the normal idle level, usually between 700 rpm and 900 rpm.

The following is a simple table that compares the starting speed of a cold car to the speed at normal operating temperatures:

It should be noted that if the speed is abnormally high (more than 1500 rpm) during cold start, or the speed does not drop for a long time, this may be a signal that there is some problem with the engine, such as sensor failure, fuel system problem, etc. At this time, car owners are advised to go to a professional repair shop for inspection and repair in time.

In short, it is normal for a Vios cold car to have a high speed when starting. This is designed by the vehicle to protect the engine and accelerate the heat engine process. Understanding this phenomenon and the principles behind it can help car owners better maintain their vehicles and ensure driving safety.
