Scania launches natural gas engine

Scania has expanded its alternative fuel and sustainable transport range with the launch of a OC09 compressed natural gas (CNG) engine at the Brisbane Truck Show.

Based on Scania’s 9.0-litre five-cylinder engine, the OC09 works using spark plugs and complete combustion in accordance with the Otto principle gas power cycle.

Scania Senior Engineer Folke Fritzson said sustainability was a driving factor behind the engines development.

“As with Europe, in Australia there is a small but growing band of operators and businesses keen to investigate the benefits of operating vehicles on alternative or renewable fuels,” Mr Fritzson said.

“Natural gas provides a CO2 reduction of 15 per cent, while biogas from waste water can cut CO2 emissions by up to 90 per cent.”

Mr Fritzson said Scania Australia have signed a memorandum of understanding with natural gas consultants NVG Group.

“This will ensure operators of Scania’s CNG fuelled vehicles enjoy a reliable fuel supply,” Mr Fritzson said.

Scania Head of Service Concepts Anders Ekstrom said the OC09 has an unusually high torque for the engine type, making it useful in a number of different applications.

“Regardless of the type of gas used, the drivability of Scania’s gas engine is in line with what conventional diesel engines can offer in terms of torque and power,” Mr Ekstrom said.

“Gas, and of course biogas in particular, are of particular interest from a European perspective with the potential for reductions in both CO2 and other emissions.”
