A fire started ahead of a forest or prairie fire to burn only against the wind, so that when the two fires meet both must go out for lack of fuel.
A premature explosion in the cylinder of a gas or oil engine during the exhaust or the compression stroke, tending to drive the piston in a direction reverse to that in which it should travel; also called a knock or ping.
an explosion in the exhaust passages of an internal combustion engine.
To have or experience a back fire or back fires; -- said of an internal-combustion engine.
Controlled fire set ahead of a forest fire to create a firebreak by reducing fuel in the path of the main fire.
An explosion of unburned or partially burned fuel through an open intake or exhaust valve system.
(1)Fire skillfully set along the inner edge of a fire control line to stop a spreading wildfire by reducing the fuel or changing the direction of force of the convection current of the fire. Using such fire to consume unburned fuel inside the fireline to speed up the line holding and mopup is usually called "burning out" or "clean burning." (2) A prescribed fire set to burn against the wind; (3) To set a backfire.
Any prescribed burn against the wind for the purpose of reducing fuels, creating a blackline buffer, etc.
Fire set downwind along a fire break.
Explosive sound from the exhaust system caused by detonation of unburned fuel mixture in the exhaust gas.
a fire burning into the wind.
a loud noise made by the explosion of fuel in the manifold or exhaust of an internal combustion engine
emit a loud noise as a result of undergoing a backfire; "My old car backfires all the time"
set a controlled fire to halt an advancing forest to prairie fire
a situation in which an area is burned out prior to the arrival of the main fire to reduce available fuel
a small explosion
a small fire set by firefighters in the path of an oncoming wildfire to burn up the fuel before the main fire arrives, thus blocking it.
Fire set to purposely influence the direction or rate of fire spread.
Gunshot-like sound from the engine or tailpipe.
A loud bang or pop from under the hood or tailpipe, usually caused when combustion takes place with the combustion chamber open.
A fire set along the inner edge of a fireline to consume the fuel in the path of a wildfire and/or change the direction of force of the fire's convection column.
A purposely ignited slow burning fire on the downwind side of the field often used in conjunction with other burn methods.
A fire spreading, or set to spread, into or against the wind.
Explosion of prematurely ignited fuel or of unburned exhaust gases in an internal combustion engine
The sudden combustion of gases in the intake or exhaust system that results in a loud explosion.
