Dynamometers by SOFT-ENGINE are the result of years of research and study carried out by our staff. In our dynos you find the long experience deriving from decades of software applications. As regards mechanics we bet on solidity, functionality and plain construction. From the alliance of both strategies we obtained a solid, precise, reliable, and highly performing product which was specifically designed for engineers and mechanicians.

The key factor of this dynamometer is inertial. The vehicle's wheels rotate the roller; the system measures the instantaneous torque by the variation of the roller(s) angular velocity while the vehicle’s engine accelerates. Therefore INERTIAL is based on an absolute principle which guarantees fine precision. It fits for engines from 0.5 HP to 1000 HP, and depends only on the inertial of the used drum. You can test the whole vehicle as well as its engine, both for cars and motorcycles, and for engines equipped with manual and automatic gear too. You can assess the exhaust gas temperature or the engine r.p.m. directly by means of a sensor (pliers). INERTIAL is the trade-name of our accelerative dynos, and it was bought by various companies and motorcycle world championship teams (Grand Prix).

The braked dynamometers are used when the mechanicians or preparers have to test the vehicle loading the engine: so you can simulate real conditions as aereodynamics influence, road simulation, climbs,  breacking-tests and naturally engine mapping.

The SOFT-ENGINE dynamometer is a very complete machine because you can make all the typical accelerative tests and the braked ones; infact it's possible to  give or not to give current to the brake.

While the roller rotates, the eddy current brake, managed by software, keep the engine braked to one or more regimes you decided. It's possible also to give a constant load during the test. In this way you have these possibilities:

1) To brake the engine to a constant regime(s), to make a mapping of the engine;

2) To give a constant load to engine, to simulate particular conditions as the presence oa a trailer;

3) To give a variable load to engine, to have a road simulation. The software's input data are  the wind velocity, the percentage of climb and more. The software "translates" these data in an appropriated current to give to the eddy current brake.

4) Running-in test: you can repeat the mapping test an imposed number of times.

5) "Inertial and Braker" test (road simulation): in this case, it is a both accelerative and braked test. You input a constant or a variable (quadratic) load to engine; while vehicle's accelerating over the drum, the eddy current brake simulates the imposed load, so you can study the real road behaviour of vehicle using dynamometer!

Our braked dynamometers trade-name is "BRAKER".
