High performance dynamic test bed

In this laboratory study and optimization activities on reciprocating internal combustion engines, in steady and transient operation, are possible thanks to the following facilities:

• AVL AC transient dyno (12000 rpm, 525 Nm, 250 kW), with AVL Emcon 400 digital controller;

• AVL Puma Open/ ISAC 400 software for simulation of driving cycles, including driver behavior;
• 8 channel AVL Indimodul unit with Concerto sw for fast data acquisition and processing;
• fast response analyzers (Cambustion HFR500, CLD 500, NDIR500 and DMS500) for exhaust THC, NO, CO/CO2 and PM measurement with millisecond response time;

• Horiba Dynas3 145 LI transient dyno (10000 rpm, 310 Nm , 145 kW), with Horiba SPARC digital controller;

• in-house implemented data slow/fast data acquisition systems based on National Instruments HW and SW.
