Cummins IS – Interact System（康明斯是交互系统）.pdf

Cummins IS – Interact System HPI-TP Fuel System Introduction Cummins 3rd generation of electronics was introduced in 1997 under the IS management system. ISX CM870 engine control system The Electronic Control Module is the control center of the system. The ECM processes all of the inputs and sends commands to the fuel system, vehicle, and engine control devices. Because the ECM is the final pathway of integration for all vehicle management systems, it is called interact or IS for short. IS From Cummins includes some of the following features Faster processing speeds and increased memory Improved fuel efficiency Integrated Centinel Control (no separate module) Improved Maintenance Monitor features Enhanced PTO programming features/ parameters Enhanced engine diagnostics/Prognostics Enhanced Security features Audit trails Enhanced Engine Protection System Anti theft protection when used with Road Relay Powertrain Protection Features J-1939 Network capable Enhanced On-Board Trip Information Battery Powered ECM clock back-up for real time clock stamping of data. Enhanced data reporting features Short Range Radio Communication (“Inrange” SRRF) System Improved Emission Reduction Above: “In-range” SRRF System Short-range radio frequency (Cummins “INRANGE” SRRF System) Fault codes can be retrieved, the ECM recalibrated etc. using this tool. Cummins small medium and large bore engines received this new system after the CELECT system. Instead of the B, C, L, and M engines, their new names are ISB, ISC, ISL, ISM.ISX and Signature The N-14 kept Celect Plus system but will not be produced after 2000 model year CM870 ECM Features The most significant change from the CELECT system is the new ECM module. It was originally the air cooled CM570. It had a greater number of inputs and output pins than CELECT PLUS - all of which are programmable. Many more features and components can be added to this system which can inter
