Improving Commonrail
Diesel Performance
Diesel engines run at a high
compression ratio and are capable
of great economy and
astounding power. When it comes to improving the performance of a diesel
engine there are many options
available.
Without a doubt the diesel performance chip is the most popular
diesel performance modification
available.
These diesel chips can work in a
number of different ways such as
by enhancing injection timing, line
pressure, or just by dumping in
more fuel.
The Injection cycle of a Common
Rail Diesel system consists of:
1. The Point that the Injector opens
(Start of injection of Fuel:-Timing
point)
2. The Fuel Rail Pressure (More load
and Revs the higher the pressure.
Critical in getting all the fuel delivered for efficiency)

3. The Point that the injector closes
(This is sometimes called injection
duration, bulk fuel delivery time
(how long the injector stays open)
A quality diesel chip can affect signals so as to alter all 3 critical areas,
manipulating the injection cycle
just like the factory ECU.
Some cheaper chips ONLY affect
‘Point 3’ which only alters bulk fuel
delivery by keeping injectors open
longer.
Other simple systems ONLY affect
‘Point 2’ by dramatically increasing
fuel rail pressure to unsafe levels
and resulting in dangerous heat
in the engine as well as poor fuel
economy.
You don’t have to sacrifice economy
to improve diesel performance. The
only way to improve performance
and economy is by altering both
fuel and timing. The by-product of
this improved engine efficiency is
more power and torque as well as
improved economy.
