A sophisticated engine test stand houses several Sensors (or Transducers ), Data Acquisition features and Actuators to control the engine state. The sensors would measure several physical variables of interest which typically include:
Information gathered through the sensors is often processed and logged through Data Acquisition System s. Actuators allow for attaining a desired engine state (often characterized as a unique combination of engine torque and speed). For gasoline engines, the actuators may include an intake throttle actuator, a loading device for the engine such as an Induction Motor . The engine test stands are often custom-packaged considering requirements of the OEM customer. They often include a microcontroller based feedback control system with following features:
ENGINE TEST STAND APPLICATIONS
ENGINE TESTING FOR R&D Research and Development activities on engines at automobile OEMs have necessitated sophisticated engine test stands. Automobile OEMs are usually interested in developing engines that meet the following three-fold objectives:
Consequently, an R&D engine test stands allow for a full-fledged engine development exercise through measurement, control and record of several relevant engine variables. Typical tests include ones that:
