Test data
Operational conditions
The engine was motored at 800 RPM, with 0.95 bar and 23° C intake air temperature as the base case. The cylinder head temperature was thermally controlled at 60° C. The engine operated with dry air with a relative humidity of 1.8%. Additionally, engine speed variations were performed (1500 and 2500 RPM). Unless otherwise stated the operational conditions are summarized in table \ref{tab:BC}.
| RPM | 800 ±7 min-1 |
| Cyl. Head, coolant temp. ( <Teng> ) | 60 ±1°C |
| Avg. Press. Intake 1 ( pin,1 ) | 0.95 ±0.002 bar |
| Avg. Press. Intake 2 ( pin,2 ) | 0.95 ±0.002 bar |
| Avg. Press. Exhaust ( pout ) | 1.00 ±0.016 bar |
| Intake temp. 1 ( <Tin,1> ) | 22.9 ±0.1°C |
| Intake temp. 2 ( <Tin,2> ) | 23.2 ±0.1°C |
| Exhaust temp. ( <Tout> ) | 33.2 ±0.5°C |
| Mass flow air in ( <min> ) | 11.4 kg/h ±2% |
| Mass flow air out ( <mout> ) | 11.4 kg/h ±2% |
| Humidity (Φ) | 1.8% - RH |
