Blipped ThrottleDescription of a 'quick press' of the throttle to make the engine rev up. | |
BlisteringThe development of hollow bubbles or water droplets in a paint film. Blistering is usually caused by the expansion of air or moisture trapped beneath the film. It can occur rapidly or any time after application as the paint film ages. Blistering may also occur from the presence of unreacted acid within the paint film. | |
Block diagramA diagram of a system, in which the main parts or functions are represented by blocks connected by lines, which show the relationships between the blocks. | |
Blocker BarGeneral term used to describe a bar that prevents an action of some kind. | |
BloomingA powder-like deposit which sometimes forms on the surface of a paint. It is often the result of a solvent component partly dissolving the pigment(s) and then depositing them on the surface when the temperature is below the 'dew point',( i.e. the temperature at which moisture will condense on the surface) | |
Blow BackIgnition of fuel in the inlet manifold causing a flame to rise out of the air intake through the carburettor. | |
