Engine Emissions/Performance
Several emission and performance tests can be realized in heavy duty engines using the active dynamometer.
Examples of performance tests on the engine;
- Power and torque tests
- Consumption tests
- Fuel additive tests
- Oil additive tests
- Vehicle wheel torque and power measurements
- Gearbox transmission ratio measurements
- Braking force measurements
Emission test performed on the engine can be listed as below;
- Heavy duty engine exhaust emissions–2005/55 EEC, ECE R49(Euro III-IV-V)(ESC, ELR, ETC) / 88/77 EEC(Euro I-II)
- Off-road vehicle and machines exhaust emissions– (97/68 EEC)
- Engine power measurements– 80/1269 EEC, ECE R120, ECE R85
- Diesel engine smoke test– 72/306 EEC, ECE R24
- Special test cycles
