DS-3000 Combustion Analysis System Screen
With two new optional features, the DS-3000 combustion analysis system now offers a wider range of measurement and analysis capabilities.
The DS-0339 Knock Expert function detects engine knocking from engine sound measured by a microphone. It can calculate and display the presence or absence of knocking, its occurrence rate, and level index in real time for each cycle.
- A single microphone measures sound pressure levels and simultaneously detects knocking in up to four cylinders.
- The detection sensitivity can be adjusted in 5 stages to allow measurement according to the sound pressure level.
- It is also possible to change the detection sensitivity and judgment level after measurement and perform recalculation.
- By combining this function's knocking level index with the frequency processing function included in the DS-0328 combustion analysis software, it is possible to determine various knocking levels—trace, light, and heavy—to match the customer's knocking index.
The DS-0365 INCA link function enables linked measurement with ETAS's INCA engine compatibility tool. It allows for time-synchronized measurement of ECU performance data and combustion analysis system calculation data.
- Data communication via LAN (TCP/IP socket)
- By linking with the engine test bench, it is possible to synchronize and measure ECU performance data and the combustion data below, making it an ideal function for efficiently performing engine tuning.
(* Measurable data: Cylinder pressure, Cylinder pressure rise rate, Combustion mass ratio position, Heat generation rate, IMEP, NMEP, etc.) - The measured data can be converted to the MDF file format via INCA and saved. Because it is an ASAM-compliant file format, it is easy to standardize the management of data with other measuring instruments.
