Broadleaf forest. Broadleaf forests are the dominant habitat of the UK and most of temperate northern Europe. There's little left of Britain's ancient wildwood, but isolated pockets of oak, beech and mixed deciduous and evergreen woodlands are scattered across the continent, and dictate its biodiversity.
Engine pinging also refered to as pinking, detonation or knocking. Pinging can be anything from a loud knocking noise to a soft tinkling sound that is emitted from the engine. If an engine has a tendency to ping, it usually becomes first audible when operated in the lower rpm range and during acceleration.
Detailed Topics. The terms valve clatter, pinging, pre-ignition and detonation describe the strange rattle or knock coming from an engine. This occurs on acceleration with the engine under a load. Each term describes a slightly different condition, but the result is usually the same with each, engine damage.
