Cylinder pressure crank angle diagram Standard cylinder pressure crank angle diagram. The positions of Start of Combustion (SOC) and MFB50 identified on diagram.
Gross IMEP (GMEP) plotted against Maximum Cylinder Pressure (PMAX). Moving the mouse cursor close to a point will identify the cycle number. Clicking on the point will change all crank angle plots to that cycle. Gross IMEP versus Maximum Cylinder Pressure diagram
Log pV Diagram Log pV Diagram
Cylinder pressure plot with SOC and MFB50 again identified. The cylinder pressure envelope has been plotted to indicate the range of data. The envelope could also be from another data file so you can compare current combustion data to a reference condition. Cylinder pressure crank angle diagram
Peak knocking pressure diagram Cycle peak knocking pressure. Note the cycle closest to the mouse pointer is highlighted in green. Clicking this point changes all crank angle plots to that cycle.
Cylinder pressure and Mass Fraction Burned (MFB) plotted on same axes. Cursors enable easy determination of values. Plot is in the alternate "MATLAB" style. Cylinder pressure and Mass Fraction Burned diagram
Cyclic data diagram All plots are easily inverted between black or white background depending on your viewing preference.
Any cycle based calculations or their statistic can be broadcast on CANbus using Vector, Kvaser or PEAK hardware. This also includes virtual CAN interfaces that can be logged in other applications such as LabVIEW or ATI VISION. CANbus configuration window
Abscissa configuration window The measurement cycle can be split in up to three resolutions. This enables high resolution analysis during the combustion phase and but with reduced processing and storage requirements.
The engine geometry and type is fully configurable. catoolRT supports spark and compression ignition, 2 and 4 stroke cycles and any number of cylinders. Engine configuration window
Analysis configuration window The types of analysis performed in real time can be configured to reduce processor loading. The number of cycles that can be acquired is limited only by system memory.
The catoolRT window can contain any number of user configured diagrams for real time monitoring or analysis of recorded data. catoolRT main window
Select channels window Selecting data for display or CAN output is simple. Select the raw channel in the tree on the left of the window and a list of analysis channels is displayed for selection.
Cylinder pressure plot in waterfall style showing current and previous fifteen cycles. Cylinder pressure waterfall plot
ATI VISION channel configuration window In addition to crank angle based data acquisition catoolRT can acquire for each combustion cycle PCM parameters via an interface to ATI VISION.
Datalist of current cycle calculations including minimum, maximum, mean and standard deviation statistics. Datalist
CAN channel configuration window Acquire CANbus channels on a cyclic basis. Signals can be defined using CANdb++ database files.
