Like the millipedes, centipedes are highly segmented (15 to 177 segments), but with only one pair of walking legs per segment (millipedes have two legs per segment). The head of a centipede has a pair of antennae, jaw-like mandibles (called forcipules) and other mouthparts.
Although compressed natural gas (CNG) is a fossil fuel like diesel, gas and coal, it is far different in terms of its impact on the natural environment.
You can see that CNG (Compressed Natural Gas) has a peak flame temperature of 1790 C & 3254 F whish is 187 C & 337 F or 9.5% cooler than the peak flame temperature of gasoline at 1977 C & 1591 F. The peak flame temperature of propane at 1991 C & 3614 F is only. 13 C & 23 F or less than 1% higher than gasoline.
