Chassis Dynamometers

Performance 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.

Details

BPVI
Inertial Chassis Dynos
2WD – 4WD - AWD

BPVI are very easy to install dynamometers, they do not require water pipes, just connect sensors and are ready to test. Operation is simple and fast, with a new data acquisition system that gives great precision and repeatability. Various models are manufactured according to the power to be measured, double and single traction and with the option of the eddy current brake.

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.

Accessories

Saenz offers complete solutions for engine testing, this includes the full range of accessories for test rooms including mobile engine bases, starting systems, cardan shafts, elastic couplings, engine adapters, cooling and water recirculation systems, fuel measurement systems and all types of sensors.

AWD linked rolls

The four-wheel drive versions have a mechanical wheelbase adjustment, for automatic all-wheel drive (AWD) it is necessary to link the axles of the rollers to ensure that the speed of all the wheels is the same and the vehicle does not go into failure. This connection is made with high resistance pulleys and timing belts capable of transmitting all the power developed in the dynamometer.

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.

SMAC data acquisition system

This system works with the highest technology, It has easy-to-use software with a large number of tools for visualization and analysis of tests. The system allow to add modules so the number of data channels can be expanded to add accessory sensors as much as desired. Communication is done through fiber optics avoiding all kinds of electrical noise problems, which is very important in a dynamometer environment, usually susceptible to this phenomenon.

More info
Easy to Run

BPVI has a pneumatic brake to hold the roll during the vehicle entrance or to quickly finish the tests after reaching high speeds. An inductive sensor can read the engine rpm for automatic synchronization between rolls and engine. This way test can be easily performed by one person from the vehicle.

Power measurement at engine, wheel and transmission losses

Tests on the dynos allow to measure torque and power on the Wheel, engine and also the power losses on transmission between engine and Wheel.

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.

Trailer Dynos

Versions of the different dyno models mounted on trailers are manufactured as a transportable option. Fully equipped with lights, elastics, shock absorbers, tires and wheels.
