SPIN designed and manufactured a complete QA dynamometer test cell facility for production hot test of Tier III and Tier IV JCB 4 Cylinder Diesel Engines.  Multiple engine variants can be tested in one cell with engine selection by barcode identification.  Included is a universal pneumatic exhaust connection system that can be easily adapted for different size turbo/compressor assemblies.  Test result data is synchronised with the existing customer server/SAP system.

Test Cell includes the following

• Test cell ventilation system
• Engine exhaust system
• Diesel fuel system with selectable fuel pressure
• Engine coolant system with closed loop cooler and additive dosing
• AC Dynamometer and inverter drive control system
• Engine PCM control interface – including CAN and J1939 protocols
• Engine test stand with quick release fluid connections
• Engine pallet system for quick rig and automatic docking with test cell
• SpinTest control and data system with Siemens S7 PLC and PC with Win CC SCADA HMI
• Barcode scanning and engine file data storage
• Host server data system
