Computer controlled engine test cell automation system for re-manufactured engine testing.


In-depth checks on engines from the production line or returned by customers are undertaken in four engine test cells, each of which has a cell computer to control a throttle actuator and dynamometer. A supervisory machine is also used to act as a central file server and an arbitrator for an Emissions Cart.

Automatic tests are run according to pre-defined schedules which contain the required speeds and torque, auxiliary parameters such as fuel temperature, and details of phase specific alarm conditions. Series of test schedules are then run in sequence on an engine, without the need for human interaction.

Key Benefits

Engine Testing - Product Engineering
  • Cost effective retro fitting for asset updating
  • Engine test cell automation
  • Automatic control sequences
  • Central storage of all schedules, test data etc.
  • Batching of schedules for increased unmanned running
  • Continual monitoring for alarm conditions


Key signals are monitored for alarms, based on the current engine conditions. In the event of a fault, a controlled or emergency shutdown routine is run to stop the engine safely and at the same time, a shutdown log is produced to show all signals during the last two minutes.

On completion, engine testing data is transferred from the cell computer to the server where it is available to engineers’ office based PCs.

The system uses Prodigy-ET software which is specifically designed for PC based automated test control and data acquisition.
