Download Engine Combustion Pressure Analysis Package

Turn Your General-Purpose Measuring Instrument into an
Engine Combustion Pressure Analysis System
This software package lets you turn general-purpose measuring instruments used primarily
in field experiments into an engine combustion pressure analysis system.
The Engine Combustion Pressure Analysis Package enables engine
combustion pressure to be analyzed using measurement data from the
WE7000 as well as the DL750 and other Yokogawa DL700 series
instruments, which are widely used throughout the auto industry. The
package also allows you to monitor analysis data during measurement by
connecting your DL750 or WE7000 to a PC through an Ethernet connection
or through USB 1.1 NEW (only for DL750).
Now that these general-purpose measuring instruments can be used for
engine combustion pressure analysis, setting up engine data analysis
equipment is much easier.

100 kS/s: 0.5 CA-approximately 8000 rpms
1 MS/s: 0.1 CA-approximately 16,000 rpms
The number of arbitrary setting points for combustion mass rate has been
increased from one to three. In addition, LNV, misfire rate and cylinder-tocylinder average value can now also be analyzed.
Transient combustion pressure analysis
Analysis of transient combustion pressure is possible thanks to the addition of intake pipe pressure, intake pipe
temperature, engine rpm, and fuel consumption as measurement items. This type of analysis is invaluable for developing
clean, high-efficiency engines for which there is strong demand.
