Residual fuel vapors apparently ignited, destroying the boat, the police said.

And it's bound to work with all that fuel vapour hanging around.

There was a thin wisp of fuel vapor trailing behind them.

The higher the fuel vapor rises in the tower, the lower its weight and the less energy it contains.

In addition, film thickness and fuel vapor are important parameters in many applications.

But investigation has not turned up the source of the spark that set the fuel vapors afire.

I really think the evidence is there for the short circuit that touched off the fuel vapors.

He saw the fire, witnessed the explosion as fuel vapor met flames and then ran back to his car.

The pilot had tried to land in the field as the helicopter used up the fuel vapors powering its engine.

When the electrostatic discharge energy is high enough, it can ignite a fuel vapor and air mixture.
