DYNAMOMETER

A dynamometer or "dyno" for short, is a device for measuring force, torque, or power. For example, the power produced by an engine, motor or other rotating prime movers can be calculated by simultaneously measuring torque and rotational speed (RPM).

In addition to being used to determine the torque or power characteristics of a machine under test, dynamometers are employed in a number of other roles. In standard emissions testing cycles such as those defined by the United States Environmental Protection Agency, dynamometers are used to provide simulated road loading of either the engine (using an engine dynamometer) or full powertrain (using a chassis dynamometer). In fact, beyond simple power and torque measurements, dynamometers can be used as part of a testbed for a variety of engine development activities, such as the calibration of engine management controllers, detailed investigations into combustion behaviour, and tribology.

Engine Test System

Ono Sokki can build up engine test system that can perform transient mode tests supporting worldwide gas emission controls including TRIAS, FTP, EURO, and ISO. (e.g. WHDC, NRTC). This system provides good reproducibility for Transient mode test. Delay compensation and rotation inertia compensation function have greatly improved as well as self-learning / predictive driving function.

Automatically processes from measurement to data output of test result, in conjunction with gas emission analyzer, tunnels, gas emission particle measurement system, smoke meter, etc.
