(in a patent) SYSTEM AND METHOD FOR ACTUATION OF AN ENGINE VALVE OF AN INTERNAL COMBUSTION ENGINE
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.

le profil du diagramme de levée des soupapes est un "profil en forme de botte". Pas de "diagramme" dans la question de l'asker. "diagramme" est au début de la phrase déjà.

"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."

: je ne crois pas que les soupapes "bootent" comme un ordinateur. La source parle du diagramme représentant la levée des soupapes.

: 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"]

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.
