Common Rail Diesel Problem
Tips to Run Your Car Economically
What is Common Rail Diesel?
For those of my readers not familiar with diesel, modern
common-rail powered diesel cars made their appearance around year 2000 (Peugeot Hdi a little earlier). The easy way
to identify common rail diesel is that all the injectors are electronic and
will have a wire running to each of them.

probably the most widely used common rail injection equipment fitted today. Don't be surprised that Mercedes
Benz, for example, fit Bosch equipment to most of their vehicles
Some of the characteristics of Common Rail
When your common rail diesel car is
running fine you will be happy even if you are blissfully unaware of just how technically sophisticated it is. It
runs so smooth, non of the rough vibrations you got with your old diesel car and I
can't help being impressed how far mine will go on a tank of fuel. In addition to
these the common rail diesel car is welcome in low pollution zones and gets a lovely
tax break from the government for being much cleaner than it's old rotary diesel
ancestor.
Important Differences with Common Rail
So how are the new common rail diesels different from the older system? The most important difference is higher
operating pressure in the common rail means that the fuel is burnt more efficiently so it's cleaner and goes
further. And it's got more performance. The possible downside of this higher pressure and better performance is
greater sensitivity. Common rail systems don't have a high tolerance to dirt or water contamination And because
they're running at such high pressure injectors need to be replaced a little sooner than the rotary type.
How to avoid Problems and Save Money
What are the jobs you can do yourself and save money? The best advice is to follow regular servicing and to
pay particular attention to the air and the fuel filters. The fuel filter needs regular
replacement because diesel is not completely clean even when it comes out at the filling station. Equally important
is the air filter to reduce those microscopic particles of dirt entering the engine in the air and causing early
wear. Be sure to check the service manual for additional filters sometimes built into the engine or
rocker cover (e.g. on BMW diesels

If you need expert help with things like injectors, sensors or regulators
there are many good independent diesel shops who will save you cash compared to main motor
companies.
