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
