THE GT-225--AN ENGINE FOR PASSENGER-CAR GAS-TURBINE RESEARCH

The intensive search for an alternative low-emission powerplant for passenger cars has led to a re-evaluation of the gas turbine for this type of service. The GT-225 engine was designed as a research tool. Vehicle tests of the engine fitted with a low-emission combustor demonstrated the following emissions: 0.11 g/km (0.18 g/mile) HC; 1.2 g/km (2.0 g/mile) CO; and 0.23 g/km (0.38 g/mile) NOx. In addition, fuel economy competitive with that of conventional passenger cars at turnpike speeds, substantially improved throttle response in comparison with earlier heavy-duty turbine engines and engine braking equal to that provided by the typical powertrain in today's cars were demonstrated. /GMRL/
