4-wheel Chassis Dynamometer

This system reproduces the conditions of on-road driving and can evaluate the various performances of four-wheeled vehicles with high precision.
It can accommodate a variety of vehicles (2WD, 4WD, EV, HEV) and supports various tests including exhaust gas and fuel economy tests, as well as environmental tests and electric vehicle energy efficiency tests.
Additionally, the highly efficient vehicle restraint method provides excellent reproducibility and stable test results.
We offer applications that comply with a wide range of regulations, including CFR1066, SAEJ2951, and JASOE014 evaluations.

It complies with the exhaust gas testing methods of various countries and regions.
