Tech/Engineering - Patents / (in a patent) SYSTEM AND METHOD FOR ACTUATION OF AN ENGINE VALVE OF AN INTERNAL COMBUSTION ENGINE
English term or phrase: a boot profile
the profile of the valve lift diagram is a so-called "boot profile", which is determined by a corresponding shape of the actuating cam 14.

"Piezoelectric actuators have very fast response times enabling the creation of a
variety of injection events [6], including rate shaping [7]. For the purposes of reduced
emissions and improved fuel economy, a special type of rate shape known as the
“boot profile” is of interest [8–10]. Fig. 1.2 shows an example of a boot-shaped
injection profile, and while it will be discussed in detail later in this thesis, it should
be mentioned here that its generation poses a unique set of problems compared to
conventional pulse-shaped fuel injections. Because the injector is hovering somewhere

between fully on and fully off during the “toe” portion of a boot shaped injection
event, injector models which account for complex phenomena including piezostack
hysteresis and needle compliance must be used. Additionally, parameter variations
with time and from injector-to-injector become more significant. The development of
the parameter estimation algorithm presented in this thesis improves the closed-loop
control of fuel injection rate in piezoelectric injectors."

neutral  FX Fraipont (X): je ne crois pas que les soupapes "bootent" comme un ordinateur. La source parle du diagramme représentant la levée des soupapes.

disagree  Daryo: can't see any computer mentioned in this text.// the only "booting" that associates with "starting a machine" is in "starting a computer" [used to be also called "strapbooting"]
8 hrs
  -> Never spoke about computer also. A "cam" can also provide a starting/booting profile. Anyway, I do agree with the other answers, which might be better.
