20  years of skills in motion

D2T is 20 years old. 20 years of engine and powertrain development, test bed engineering and test bed equipment.

As time goes by, we attain various skills. Thanks to them, today we devise new engine calibration methods and offer state-of-the-art tools such as MORPHEE 2, our test bed automation and simulation system. This has required selfless passion - and the support of our customers!

20 years of experience makes a difference. It gives a unique blend: expert technicians who, very often strongly experienced on our customers sites, speak your language and follow your testing methodologies; innovation through our partnership with the IFP (Institute of the French Petroleum); flexible tools for your test beds, allowing you to reduce test durations.

Tomorrow …
Modelling and simulation technologies will offer new perspectives, hybrid and electric vehicles will take to our roads ... but the experts at D2T will always be in search of the optimal solution.
Then, ready for 20 years more?

IN BRIEF

Aerospace Testing
Within its strategy framework, D2T will participate in the Testing Aerospace exhibition  in Hamburg from 18 to 20th of May, 2010. Experts will present to you (exclusively) innovative solutions in automation and real time simulation (MORPHEE 2).

Appointments                 
Gaetan MONNIER was appointed as the new Chief Executive Officer of D2T. Andre QUIGNODON was appointed as new Chairman of the Board of Directors.                 

Major step for the OSIRIS combustion analysis system
OSIRIS continues to expand, offering an optional new acquisition mode called Angle & Time. Now you can perform time-based acquisition in parallel with standard angular acquisition. This new feature takes a fixed period of engine cycles, defined by crankshaft angle from top dead centre. The goal is to allow precise analysis for some periods of engine cycles at very high sampling frequencies, still guaranteeing perfect synchronisation with angular data. This function is already in use on injector tuning (analysis of command …., injected flow…)

Reserve your Euro 5 - Euro 6 tests

In 2009, in spite of difficult economic conditions, D2T continued its ambitious investment policy. Our investments were concentrated on our CESAME test centre located on the  Madrillet science park near Rouen. This centre is dedicated to the development and  calibration of vehicles and will very soon possess one of the world’s most advanced  facilities compatible with present and known future standards (EURO 5 and 6), housing a 4 x 4 chassis  dynamometer in a climatic cell down to - 7°C. This test centre, opening in March 2010, will handle validation of all vehicles and utilities, gasoline / diesel in standard or hybrid form.
With D2T, tomorow's propulsion is starting today.

Simulation of a vehicle and its driver in a test bed

On the road, driving situations are varied; stops at lights, startup phases, stable highway speeds; so many situations are reproduced in automotive homologation cycles. The real evaluation of a vehicle’s performance in these driving cycles is often done at the end of the development phase of an internal combustion engine during its integration to the test vehicle. This late phase allows too small a degree of freedom of driving control relating to development tests performed on a chassis dynamometer.
D2T suggests addressing this problem directly in dynamics tests through the introduction of real-time simulation in its MORPHEE 2 automation system. This has the effects of reducing development time and improving final engine calibration. SIMUDYN 2 is an application developed by D2T which reproduces on a test bed the behaviour of a human driver and the dynamics of a motor vehicle using standard driving cycles or those specific to the end user. SIMUDYN 2 offers the end user a large number of parameters allowing him to customize its simulation at these levels:
- Driver characteristics, acceleration, gearbox shift rules....
- Vehicle mass, inertia of wheels, gearbox...
- Road cycles, consideration of gradients, complete customization of the road cycle...
