A ten-month programme investigating the viability of using clean-burning methane – in the form of compressed natural gas (CNG) and compressed biogas (CBG) – to power passenger vehicles inSouth Africa, has shown that the conversion of petrol- or diesel-powered minibus taxis and urban buses to a dual- or bi-fuel system is economically viable and can offer significant cost savings.
Bi-fuel vehicles are able to run on diesel fuel or natural gas, while dual-fuel vehicles are able to run on diesel fuel and gas simultaneously.
The real-world fleet trial, funded by the Industrial Development Corporation and conducted by automotive development and research firm Cape Advanced Engineering (CAE), saw eightGauteng-based minibus taxis converted to a bi-fuel system and one bus converted to a dual-fuel system.
Once converted, the vehicles were refuelled by three commercial filling stations, two provided pipeline CNG and the third a blend ofCBG and pipeline CNG.
The study investigated fuel consumption, vehicle operating costs,oil analysis and the financial viability of vehicle conversion to a dual- or bi-fuel system.
