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
