Dirt refers to harmful deposits that can form in engines, causing a loss in engine performance. They can build up over time and over a range of driving conditions. Dirt is a well-known issue in car engines.
The critical engine components that dirt affects are the intake valves and fuel injectors in petrol engines and the fuel injectors in diesel engines.
When an engine is affected by dirt the driver may notice a loss of responsiveness, for example the vehicle doesn’t perform as expected when accelerating.
In diesel engines a build-up of dirt in the fuel injectors restricts the flow of fuel causing a reduction in maximum engine power. The loss in power may be felt by the driver as the vehicle may no longer accelerate as quickly as it could when the vehicle was new.
In petrol engines slimy or sooty deposits can build up on the intake valves. The driver may notice a momentary hesitation or loss of responsiveness when accelerating.
