troubleshooting and repairing diesel engines fourth edition pdf

As an instructor of electrical/electronic systems for the past 15 years I’ve witnessed the effect of this change on the diesel industry firsthand. The growth and
usages along with changes in the area of electronics have allowed for many of the
advancements that have taken place with diesel engines and was the only way to
meet the EPA guidelines. The large numbers of advances in electronics have also
meant that the amount and levels of training required by today’s engine technician
have increased dramatically.

What has this meant to those affected by the use of all these electronics? For the
engineer, fewer moving parts will provide the ability to design systems to meet most
of the requirements or demands placed upon them by the EPA or the individual customer. This flexibility allows the engine manufacturer the ability to make faster changes when design dictates. The customer gains the ability to make updates toprogrammable parameters to match changes in equipment demands. The technician, with help from ECM/ECUs, sensors, programmed software, and diagnostic tooling, can diagnose problems faster and more accurately. This results in an eventual savings for all, but especially to the customer, because overall reliability today has increased greatly and this affects down time and bottom line. Engines today are better than ever and have come a long way in helping to keep the environment clean.

Where is all of this change to engine technologies eventually going to take us?
Even with all the advancements today in technology that will someday diagnose the
problem and tell what part to change, we will always need the engine technicians
to program the parameters, help diagnose the problem, change parts, and verify that
the results fixed the original problem. There is already a big shortage of qualified
and trained diesel technicians around the world.

Additionally, the need is there to
require training of potentially 50,000 to 100,000 diesel technicians by 2010. Being a
diesel engine technician is a very demanding career and a career that is going to
become more and more important in the future. The future challenges and potential
rewards for the trained technician are going to create some very interesting situations within the industry in the very near future.
