The speed of the flame front is directly affected by the compression ratio, fuel mixture temperature, and octane rating or cetane number of the fuel. Leaner mixtures and lower mixture pressures burn more slowly requiring more advanced ignition timing.
Engine knocking. In spark-ignition internal combustion engines, knocking (also knock, detonation, spark knock, pinging or pinking) occurs when combustion of some of the air/fuel mixture in the cylinder does not result from propagation of the flame front ignited by the spark plug, but when one or more pockets of air/fuel mixture explode outside ...
Shindaiwa Incorporated is a global manufacturer of welding machines, generators, agricultural and forestry machinery, and outdoor power equipment. The company originally manufactured electrical and industrial products. Shindaiwa launched its first chainsaw in Japan in 1955.

Both gas and electric blowers stir up particulate matter, dust, mold, pollen, and pathogen-containing bird and animal feces into the air that we (and insects and wildlife) breathe.
Soot blower. Long Retractable Sootblower utilizing steam as a cleaning medium. A sootblower is a device for removing the soot that is deposited on the internal furnace tubes of a boiler during combustion to prevent plugging of the gas passes and maintain boiler efficiency. The world market leader is Clyde Bergemann Power Group.
A leaf blower, commonly known as a blower, is a device that propels air out of a nozzle to move debris such as leaves and grass cuttings. Leaf blowers are powered by electric or gasoline motors. Gasoline models have traditionally been two-stroke engines, but four-stroke engines were recently introduced to partially address air pollution ...
A chainsaw cutting a small wooden board. A chainsaw (or chain saw [1]) is a portable handheld power saw that cuts with a set of teeth attached to a rotating chain driven along a guide bar. Modern chainsaws are typically gasoline-, electric-, or battery-powered and are used in activities such as tree felling, limbing, bucking, pruning, cutting ...
Crankcase dilution is a phenomenon of internal combustion engines in which unburned diesel or gasoline accumulates in the crankcase. Excessively rich fuel mixture or incomplete combustion allows a certain amount of fuel to pass down between the pistons and cylinder walls and dilute the engine oil. It is more common in situations where fuel is ...
