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.
With CNG fuel, the car delivers better mileage and has a comparatively lower running cost. Considering the capacity of a standard CNG tank, it can store around 8-10 kg of gas. On the other hand, LPG is regarded as one of the most commonly-used alternative fuels in India.
