Chassis Dynos
Chassis Dynos allow to test vehicles and measure power without having to dismount the
engine. Power and torque available in the wheel, engine and losses in the transmission can
be measured. These dynos allow testing in the shop, avoiding street or road tests which
mean risk, difficulties and imprecise conclusions.
We build alternatives for cars, trucks, motorcycles, ATVs and karting, in inertial format,
with electric or hydraulic brake and also combined.

Inertial Chassis Dynos for motorcycles, ATV and kart
Various models of chassis dynos are manufactured for these vehicles. All of them are very easy to assemble with portable structures that do not require installation. Operation is very simple and fast, with the latest technology data acquisition system that offer great precision and repeatability.
We manufacture different models according to type of vehicle and power to be measured. Inertial tests do not have a physical test limit, any vehicle can be mounted on the rollers and make an acceleration test. The limitation in these cases will be the quality of the measurement: as more power is tested, inertia must be higher, if it is not enough, the run will be too fast. In these cases the measurement will be inconsistent and not repetitive, with a significant margin of error.
Rolls have a special surface grip that avoids slipping and allows to reduce the load of the vehicle on the roller, minimizing heating and deformation. These dynos are also equipped with a pneumatic brake to stop the roller at the end of the tests and lock it for assembly and departure.
Below are presented different alternatives regarding diameter of the rollers, which is closely linked to the inertial moment and therefore to the equivalent mass of the rollers that the vehicle must "push".

Data acquisition system
Smac is a new high-tech data acquisition system that offers maximum precision and repeatability. Measurements show real data since the dynamometer allows to carry out quality tests, no interpolations are made that “draw” unreal curves and hide details of the real performance of the vehicle.
The equipment communicates with fiber optics which avoids electric noise problems in an environment as complex as a dyno test room. With dedicated software with very simple operation that records and presents reports of engine performance and all the variables according to different test programs. The system has basic channels for measuring rpm, torque and power, a weather station and offers a variable number of channels for other types of sensors that you wish to incorporate, such as a lambda probe, pyrometer, temperature or pressure sensors, etc.
Smac also includes an inductive sensor that monitors the engine revolutions and allows the motor and roller rpm to be synchronized automatically. This way, the tests are carried out in a comfortable and agile way, requiring only one person without having to get off the motorcycle, karting or ATV.
Eddy current Retarder
All chassis dynos have the option to fix an eddy current brake to give variable load to the tests. It is possible to maintain real conditions at sustained speed and torque. The system has a torque control that adjust the load or speed levels automatically, this way the complete injection map can be adjusted in all throttle positions. Another test program is the simulation of real road with different air friction factors and/or configurable slopes in historic chart.
Command stand
Support for notebook or keyboard and mouse with all the controls of the dyno, offers total control without getting off the bike.
Motorized front wheel Clamp
It allows to set in position the motorcycle and fix it quickly and safely by pressing a single button. Avoid the need to tie the motorcycles.
Mobile Blower
In order to maintain the suitable temperature of the vehicles, we offer a 1.5HP mobile forcing with steering cone and flow deflectors to ensure stable engine conditions in different tests. Mounted on a mobile base, with height adjustment and projection angle.
Dinamómetros tipo tráiler
Every chassis dyno can be mounted on trailers as a transportable option. Fully equipped with lights, elastics, shock absorbers, tires and wheels. Spherical hitch and telescopic legs.
