CityCab Introduce CNG Cabs
Saturday, 2nd November 2002
Toyota Japan supplied a trial fleet of Toyota Crown cabs, powerd by CNG, to CityCab. The CNG Cab on Singapore carried a registration number of SHB 4899S. In conjunction with the launch, CityCab took part in the Clean & Green Week Carnival on 2 to 3 November at the Woodlands Civic Centre. The public was given free rides around the carnival area in CityCab's first Compressed Natural Gas (CNG) taxi named 'Cinergy'.
Compressed natural gas (CNG) is a fossil fuel substitute for gasoline (petrol), diesel, or propane/LPG. CNG is an environmentally clean alternative to those fuels, and it is much safer than other fuels in the event of a spill (natural gas is lighter than air, and disperses quickly when released). CNG is made by compressing natural gas (which is mainly composed of methane [CH4]), to less than 1% of the volume it occupies at standard atmospheric pressure. It is stored and distributed in hard metal or reinforced plastic cylindrical containers at a pressure of 200–248 bar (2900–3600 psi).
CNG is used in traditional gasoline internal combustion engine cars that have been converted into bi-fuel vehicles (gasoline/CNG). In response to high fuel prices and environmental concerns, CNG is starting to be used also in taxis, pickup trucks, transit and school buses, trains and even small passenger cars.
