Engine testing involves measurement of rotating speed and torque of the engine by applying load controlled by a dynamometer connected to its output shaft. HORIBA has developed various types of dynamometer for the purpose of engine testing. They are mainly classifi ed into two types; one is absorbing only dynamometer such as hydraulic dynamometers and eddy-current dynamometers, the other is absorbing and driving machines such as AC, and DC dynamometers and oil hydraulic dynamometers. HORIBA's DYNAS3 dynamometers, based on AC synchronous and asynchronous motor technology, is the latest model range and has grown into one of the world's leading engine test dynamometer series. HORIBA's solutions for engine testing cover a wide range of applications such as the standard TITAN engine test bench systems, containerized test system, tilt & turn rigs, turbine engine test bench as well as their component parts such as dynamometers, the STARS test automation system and the SPARC real-time digital controller.
