GM tests gas-saving engine
Sunday, August 26, 2007
GENERAL Motors Corp (GM) is testing a combustion engine that could increase fuel economy in traditional engines by up to 15 per cent, the automaker said on Friday.
The process will help vehicles get more miles per gallon without requiring the emissions controls that increase the cost of engines.
The engine would save fuel by using compression of fuel and air, rather than a spark, to produce heat required to power the engine. GM is testing the technology in two drivable concept vehicles Saturn Aura and Opel Vectra.
GM said it is working to refine the engine before it will be available on the mass market.
"Although our development costs have been substantial, we have made tremendous strides," said Uwe Grebe, executive director for GM Powertrain Advanced Engineering.
