But these fuels are smoky and may cause serious lung and eye diseases.

Steep topography, dry fuel, and hot conditions caused the fast spread of fire.

Excessive fuel entering (flooding) one or more cylinders in liquid form due to or other abnormal operating conditions can also cause hydrolock.

There really is not the same danger blowing out a candle because the fuel can't really accidentally be spread and cause a fire.

In the last couple millennia, or more, fossil fuels and changing ocean chemistries have caused a sharp warming of the climate.

If a valve leaked fuel into a faulty hose, fuel could have dribbled onto hot surfaces and caused a fire.

He speculated that burning fossil fuels would eventually cause atmospheric carbon dioxide to double, leading to warmer weather.

The Association expressed concerns that alcohol-blended fuel could cause damage or problems to engines that were not originally built to run on such fuels.

Therefore higher-cetane fuel usually causes an engine to run more smoothly and quietly.

We know fossil fuels cause global warming and yet we continue to use them.
