lämminkäynnistykset

Lamminkäynnistykset, a Finnish term, translates to "warm starts" or "hot restarts" in English. This refers to the process of restarting a system, such as a computer or an engine, without completely shutting it down. Instead of a cold start, which involves a full power-up sequence from an off state, a warm start assumes that some components are already powered and in a functional, though possibly non-optimal, state.

In the context of computers, a warm start can be initiated by a software command or a reset button. It typically bypasses some of the initial hardware checks and diagnostic routines performed during a cold boot, leading to a faster startup time. However, it may not resolve certain deep-seated software or hardware issues that a full cold restart could address. This is because certain errors or memory states might persist through a warm start.

For internal combustion engines, a warm start refers to restarting an engine that has recently been running and is still at or near its operating temperature. This process is generally easier and more efficient than a cold start, as the engine's components are already expanded and lubricated, and the oil is at a lower viscosity. This leads to less wear and tear, reduced fuel consumption, and quicker attainment of optimal operating conditions. The term is often used in contrast to "cold start," which implies the engine has been off for a significant period and has cooled down considerably.
