/ 85 LOAD UNIT FOR ENGINE TEST CELLS AVL DynoSpirit New requirements for engine testing demand new types of dynamometers. Standard dynos cannot be used to test an inline engine with the original vehicle exhaust system on an engine testbed because there is no space for it. The DynoSpirit hangs in a frame and the exhaust system can be installed in the available space below. The motors used for DynoSpirit have a proven, robust design that has already been in use in many applications. TORQUE MEASUREMENT The low inertia of the dynamometer allows a stiff driveshaft connection to the combustion engine. The stiff connection provides the possibility of fast torque measurement and control. The AVL permanent magnet motors have high torque linearity and high accuracy in the open torque control loop. In combination with the AVL dynamic control package (KIWI, Emcon, ISAC), the DynoSpirit offers the highest level of dynamics and accuracy for torque control. APPLICATIONS • R&D, quality and endurance testing for engine and components • Precise simulation of vehicle load on an engine test cell • Calibration of engine management systems • The dyno is designed for extreme ambient conditions BENEFITS AT A GLANCE • Very high speed gradients thanks to an ultra low rotor inertia • Particularly well adapted for applications where space is critical due to very small motor dimensions and weight • Top dynamics and accurate torque control thanks to the Highly dynamic, compact AC drive system for testing combustion engines consisting of very high motor torque linearity state-of-the-art permanent magnet motor and IGBT frequency converter for 4Q operation with a digital real-time interface. Enables, together with a portal frame, testing of the original exhaust system.. • Higher torque measurement accuracy than with a foot-mounted asynchronous motor thanks to the lower temperature influence from the rotor • Robust and compact design for operation under extreme ambient and environmental conditions
