It is not the strongest of the species that survives,

nor the most intelligent that survives.

It is the one that is

MOST ADAPTABLE TO CHANGE

[Modern paraphrase; Darwin never wrote with these words.]

Choice of architecture and sensors/actuators

Conception of controls strategy & early evaluation of reliability

Q4 : what is the risk on air path and after treatment control

of an exhaust temperature sensor failure ? In this case,

can I estimate a value to replace the measured signal.

Q2 : with a dual loop EGR, can I estimate the EGR flow of both circuits?

And can I use the air mass flow sensor to control the two loops ?

Q3 : what is the severity level of an intake throttle failure?

No impact / risk on air path control / risk on pollutants

emissions / risk to stall the engine / risk for the safety?

Q1 : on two stage turbochargers can I control the boost

pressure with only one intake pressure sensor? should I

introduce an additional sensor between the two compressors?
