Heavy Duty Chassis Dynos

Vue d'ensemble

HORIBA has a long tradition in planning and producing Heavy-Duty Chassis Dynamometers. We cover all important application areas like emissions, performance, climatic and NVH. The systems have standard interfaces to the HORIBA emission systems and so form part of the total emissions solution from HORIBA.

Our automation systems in combination with the long lasting and low maintenance dynamometers are able to check trucks and buses on all important US Heavy-Duty Vehicle Test Cycles.

Fonctions

Chassis Dynamometer EMDY 72 includes mechanical, electrical and control equipment to provide road-equivalent loading for trucks and other vehicles such as single-axle transit buses, dual live-axle Class 7 and 8 type and highway trucks. This system, along with emissions test equipment, are the primary elements in the analysis of exhaust from heavy-duty vehicles operating on diesel fuel, natural gas, liquefied petroleum gas (propane), methanol, ethanol, gasoline and blends of fuels. Of course it allows testing of the entire vehicle or multiple vehicle components under consistent and defined test conditions. By that, you gain a reduction of road testing risks and costs.
