2. Piston / Valves assembly design optimisation:
-Statistical analysis and optimisation of the
lifting of the valves at any angular position
of the camshaft.
-Statistical analysis and optimisation of the
distance between the valve and the
different possible interference elements
(notably the piston).
-Inclusion in the model of the tilting effect
of the valves and any position
(this tilting may have an effect on
the accuracy of the system).
-Statistical analysis and optimisation
of the swept volume
(the volume between the head of the
piston and the top of the cylinder.

3. Chain layout design & statistical optimisation:
- Statistical analysis and optimisation of
the position of the tensionner piston in
function of all the tolerances of the other
components present in the system.
- Inclusion in the model of all contact
conditions (including complex chain /
cam contact) and tolerances.
- This statistical analysis and
optimisation may also include the forces
applied on the chain and the
corresponding elongation of the chain.

4. System level Engine design optimisation:
- Any system level parameter of the
engine that involves non dynamic effects
can be easily analysed.
- Wear / thermal effects laws can be
included so that for example the Mean
Time Between Failure can be evaluated
and optimised.

5. Turbo systems design optimisation:
- Statistical analysis and optimisation of
the tilting angle of the fan’s shaft in
function of all the tolerances present on all
the components (including the tolerances
on the bearings).

6. Transmissions design optimisation:
- 1D tolerance stacks relative to the fitting
Of the different components of the
transmission.
-Statistical optimisation of the operation of
transmission actuation elements (Clutch
and gear changing mechanisms).
-Statistical analysis and optimisation of
automatic transmissions park brake
mechanism.

7. Comments from Enventive Users…
“We can conceptualize design concepts ten times faster in Enventive than we can with our native CAD
system…
Rather than seeking to simply avoid problems, by using tolerance-based optimization early in the product
development process, well up-front of traditional CAD, we’re able to use Enventive to target and achieve
optimized design solutions and aggressively establish competitive product offerings.”
Yves Le Pottier – Electrical Device Supplier
“I cannot leave a discussion of Enventive without mentioning it is fun to use. The software is graphically
based. Sketches and graphical representations of the parts drive the models. This, coupled with the easy
to use interface, creates “Stack-up Junkies” who want to do the analysis because the software helps
them easily visualize the impact a design change can have on the product.”
Eric Pattok – Delphi Steering Systems
“Our engineering team has been able to use Enventive after 4 days of training. We have been able to
correct some design mistakes that were done in the past due to the limitations of the tools we were
using. In the end, our customer praised us for the speed and professionalism with which we have been
able to complete and present the DFSS phase on this project.”
Pedro Lopes – Ficosa International
