Käyntihäiriö

Käyntihäiriö refers to a malfunction or irregularity in the operation of an engine, most commonly an internal combustion engine. This term, originating from Finnish, describes a situation where the engine does not run smoothly or consistently. It can manifest as misfires, hesitations, sputtering, or an uneven idle speed.

The causes of käyntihäiriö are varied and can stem from issues within the fuel system, ignition system, or air intake system. Problems with spark plugs, ignition coils, fuel injectors, fuel pump, or air filters can all lead to improper combustion and thus, käyntihäiriö. Additionally, mechanical issues like worn piston rings, valve problems, or a faulty oxygen sensor can also contribute.

Diagnosing käyntihäiriö often involves checking for error codes in the engine control unit (ECU), inspecting ignition components, and testing fuel delivery. The symptoms can range from minor annoyances to significant performance losses and increased emissions. Addressing käyntihäiriö is important for maintaining engine health, fuel efficiency, and overall vehicle reliability.
