| The
BRC Generation 3 equipment is called "flying injection".
I am informed that eta is Latin for efficiency.
By
fitting gas injectors close to the inlet valves, the problem of
having an explosive gas mix in the manifold is almost completely
eradicated, meaning that back fire problems are eliminated. The
fact that the gas inlet is much closer to the engine than on the
previous generations means that the engine responds much more
quickly and as the fuel is a gas, the combustion is more complete
than with petrol.
The
description that follows is as basic as I can make it, but I have
had to assume that you, the reader, possesses some mechanical
knowledge. However if it doesn't make sense, contact me and all
will be revealed.
The
back end kit is identical to earlier systems and indeed the Vaporizer
under the bonnet is very similar, apart from being non-adjustable
and having a vacuum pipe running between it and the inlet manifold
to ensure that the correct pressure differential is maintained
in all circumstances.
The
gas flows from the Vaporizer to the distribution unit where the
volume of gas injected into the inlet manifold is controlled.
Two motors adjust the volume of gas by receiving signals from
the Ecu, which in turn analyses signals picked up from the following
sources:
RPM
signal
To gauge engine speed
Throttle
position sensor
Lambda
(Oxygen) sensor
To analyze exhaust emissions
