Home Services Engine dynamometre

These test-rooms are equipped with Super Flow SF901 and Super Flow SF900 measuring equipment.

They have a hydraulic brake system [water], and readings of up to 900HP and 10.000rpm.

In the control panel, the electronic control can modify the brake load so as to stabilize the engine at a specific amount of revs, thus allowing the programming of automatic test cycles [durability], and to do constant-acceleration tests [from 25 to 2.000rpm] for measuring typical power curves of the engines [power, torque, consumption, etc].

They also have programmable outlets for handling relays which can be used for the automatic start/stop
of an engine, opening or closure of electro-valves, etc.

Data-acquisition in real-time means that all the information can be obtained during the test of a vehicle, and in this way all the parametres can be interrelated so as to obtain a complete analysis of the results and represent them graphically or in a panel via the computer.

Safety limits [maximum and minimum] for different variables can be programmed, so as to preserve the engine in case of any abnormality in its functioning.

Sensors:
Sensors are incorporated in the dynamometers, so as to obtain the following parametres:
Engine Revs.
Torque [by relating the torque and the engine revs, the power figures are obtained ].
Temperatures [of cooling fluid, oil, air admission, cylinder head, etc].
Oil Pressure.
Negative intake pressure or negative pressure of the sump.
Fuel-flow [pressure].
Intake airflow.
Thermocouples [12].
High-precision, A/F ratio equipment [plus/minus 0,02 A/F] [12].
Gas flow due to loss through the rings [blow by].
Additional measuring equipment , such as an oscilloscope, accelerometers, manometers, etc, can be added.

Auxiliary equipment:
Temperature-regulating equipment corresponding to cooling fluid, oil coolers, exhaust silencers, high-flow ventilators, etc, completes the area’s equipment.

The dynamometres include the corresponding equipment for the control and setup of the fuel-injection and the ignition of the engine.

This room includes a Super Flow SF 830 rolling-road dynamometre and a 200HP encircling ventilator capable of stabilizing temperatures of the engine compartment, manifold, etc, simulating the engine’s cooling and air-feed conditions which the vehicle would encounter on a road or at a race track.

Rollers:
It has two rollers of 1.050mm diametre, joined by means of a differential?????? to the brake, on which the tested vehicle’s wheels connected to the transmission lean upon. The rollers’ inertia is 970 Kg, similar to that of a present-day vehicle.

Brake:
Brake load is of 1.000HP, depending on the elapsed time.

Control Panel:

The electronic control can modify the brake load so as to stabilize the speed and varied high-precision tests.
So as to be able to program urban motoring cycles and go ahead with fuel-consumption tests, a servo-electric gadget as a load on the engine.

Data-acquisition in real-time means that all the information can be obtained during the test of a vehicle, and in this way all the parametres can be interrelated so as to obtain a complete analysis of the results and represent them graphically or in a panel via the computer.

The test-bench incorporates sensors for obtaining the following parametres:
Vehicle’s speed.
Torque.
Air/Fuel ratio, of up to 12 cylinders simultaneously.
Engine horsepower [with more than 2.000 test having taken place so far, our dynamometre corrects with high-precision the power figures, bearing in mind the type of tyres, type of gearbox and differential, traction or propulsion, and the mass of each car tested].
Thermocouples and Flowmetre.
Scales for measuring fuel-consumption.
Detonation equipment.
Opacimetre [exhaust fumes].
Positive/negative/relative-pressure sensors.
Temperatures [brakes, differential, air-admission, fuel, exhaust manifold, tyres].

Additional measuring equipment such as an oscilloscope, accelerometer, manometer, etc, can be fitted to the data-acquisition system.

It allows work on the setup of the fuel-injection mapping and ignition setup, as optimum conditions are here found so as to simulate a car travelling on a open road or on a race track.

Uses:
Dynamometres are used to measure an engine’s dynamic performance, and the evolution of the development stages which are added to it.

They are used for the running-in cycles of engines, or of their components, prolonging their use.

Each one of the four rooms, totally equipped with Super Flow products, is used for a definite purpose and for specific work programmes.
