| Collectors |
 The
collectors are the linking element between the engine and the exhaust.
They are therefore the first to be hit by the burned gas coming from
the combustion chamber. So, inside them the gas temperature and speed
is very high; it is therefore evident that they are very important
for a proper working of the entire exhaust system: they will have
to insure the flow of gas in a fast and smooth way, resisting at the
same time to all thermic and noisy solicitations transmitted by the
gas itself. For the above reasons it is very important to realise
collectors with the right conicity accordingly with the performance
evolution and, in presence of a multi-cylinders four strokes engine
with the classic spark sequence (and not the “big-bang”),
we will have, when the engine is running, to level off the gas pressure
in all header collectors with the joint compensators that, if in the
right position and quantity, will insure the lack of “holes”
in all engine power curve. There is therefore the need of using resistant
material but with a relative light weight as the actual technology
requires. |
