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.
CNG / LNG â the Distinction. ï¡CNG and LNG are simply two different ways natural. gas is stored. ï¡There is no such thing as an âLNG engineâ or a âCNG. engineâ. ïItâs not engine type that differentiates LNG and CNG, itâs. how the fuel is stored and supplied to the engine. ïBoth are delivered to the engine as a gas.
