COMBUSTION ANALYSIS
the only method of obtaining maximum power or efficiency economically and in a minimum amount of time.
In-cylinder
pressure measurement of gasoline spark ignition internal
combustion
engines with nonintrusive Kistler
transducers. Two-week project completion with
same-day 85-page Performance
Combustion Analysis Report presented in
digital and bound format (detail).
The In-cylinder pressure measurement
format includes
- Individual cylinder pressure measurement every engine cycle for 200 engine cycles
- 720 degrees of crankshaft rotation each engine cycle
- 288,000 data points for each 200 engine cycle test
- Crank angle measurement to .5 degree with AVL 365 optical encoder
- 135 Charts and 13 Spread sheets for each test
- In-Cylinder pressure cyclic inconsistency each cylinder
- In-Cylinder Peak Pressure Location Variability each cylinder
- Individual cylinder pressure per degree pre cycle
- Cylinder pressure vs cylinder volume
- Cylinder Variability Cylinder to Cylinder
- Maximum performing cylinder …Minimum performing cylinder
- IMEP Indicated Mean Effective Pressure
- PMEP Pumping Mean Effective pressure
- NMEP Net Mean Effective pressure
- Heat Release Burn Rate
- Crank angle of Mass Fraction Burn
- Cylinder Pressure Cyclic inconsistency each cylinder
- Cylinder Pressure Variability Cylinder to Cylinder
- Mean Effective Pressure each engine cycle
- Heat Release
