Broadleaf forest. Broadleaf forests are the dominant habitat of the UK and most of temperate northern Europe.

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.
If it is ignited before top dead center it can cause the valve train to generate a noise that is known as engine ping. In most cases engine ping is caused by timing that is too far advanced. If the timing is too far retarded the most likely symptom would be a hesitation lack of power and very poor fuel economy.ow to test for improper ignition timing. When the ignition timing is not correct there are a few tests that can point to the car problem. The main symptom of a timing issue would be incomplete combustion at different engine speeds.
