Angle Based Measurement & Analysis Software
ExAngle UPDATE
Combustion Analysis Software creates efficient development environment
The ExAngle has been reorganized based on the combustion analysis measurement technology that we have accumulated over many years, and has been reborn as the system that handles high-speed sampling measurement data for any rotating objects, not just internal combustion measurement.
EX-4100 ExAngle
This is basic software that uses a 1MHz high-speed unit for combustion analysis and can record with a minimum resolution of 0.05 degree.
DS-0328T Transient combustion analysis function
DS-0335 SYNC measurement function
DS-0349 Crank angle pulse period measurement function
DS-0360 Encoderless measurement function
EX-0428 DS Combustion Analysis Function
All the calculation functions of the following existing products are included,
such as indicated mean effective pressure, combustion mass fraction burned,
combustion variation rate, knocking peak, combustion noise, and torque.

DS-0337 Combustion noise analysis function
DS-0329 Knocking analysis function NEW
DS-0361 Torque fluctuation analysis NEW
EX-0436 DS Combustion Link Function
The ExAngle is controlled from the bench system via LAN communication. It can control to recording and data transmission/reception.
EX-0483 CAN Function
The results of ExAngle calculations can be sent to the CAN bus, and CAN information from the vehicle can be received and recorded.
EX-0439 Knocking Expert Function NEW
By measuring engine noise with a microphone, knocking can be quantitatively indexed.
Features
- It can be used not only for combustion analysis but also for more general-purpose high-speed angle sampling measurement.
- The NonStop architecture allows constant monitoring even during hazardous testing.
- In addition to the main recording, sub-recording can be operated simultaneously, thus you won't miss any unexpected sudden phenomena.
- The intuitive GUI reduces tester errors. It is also useful for outsourcing testing operations and expanding overseas.
Combustion Analysis System Configurations
NONSTOP monitoring + Sub-recording enhances fuel test monitoring.
In order to achieve carbon neutrality, the evaluation and verification of new fuels and new devices have been increasingly important. With the ExAngle, testing can be carried out safely and efficiently even with limited development resources.
The ExAngle does not stop monitoring even during calculations after data recording or when saving files, thus testers can carry out their work with peace of mind. In addition, sub-recording for abnormality monitoring can be performed in parallel with normal main recording, making it possible to preserve abnormality data while protecting equipment.
