Description of Automotive Diesel Engine
An eddy current dynamometer provides a variable load on the engine, enabling the characteristic power an d torque curves to be reproduced in the laboratory. The system comes complete with extensive instrumentation, including rpm measurement, torque (from which power can be calculated), plus various temperatures, pressures and flows .
The whole system is designed to be linked to a computer using the software provided. This provides real time monitoring of the various sensors, with a wide range of data logging and graphical display options. The dynamometer and throttle can both be controlled electronically from the software, which makes installation into a closed test cell very straightforward, and enables for remote computer operation.
