Common Rail Invasion

May 15, 2009

I think of the Ford/International 6.0L platform as a “bridge” because it spans the gap between the 7.3L with electric-over-hydraulic injectors and the coming 6.4L common rail engine. Common rail injection, made possible by today’s powerful on-board microprocessors, will be the industry standard for a long time to come. The fuel rail pressure, ranging from 5,000 to more than 20,000 psi, is controlled by the electronic control module (ECM). The operation of the injectors is very simple: They still pop, but high fuel pressure on top of the injector piston prevents it until the ECM or fuel injection control module (FICM) sends about 90 volts to operate the injector solenoid, which opens a pressure bleed in the chamber above the piston.

Diesel Diagnostics

April 14, 2009

Scan tools are only part of the key to the diagnostic process, knowing when to use them is equally important. If a vehicle comes into your shop with a drivability complaint, should plugging in your scan tool be the first step in diagnosing the problem? Probably not — keep in mind that even though modern engines have sensors and computers that monitor just about every aspect of their operation, deep down they’re still machines that require air, fuel, and oil to run. Remember — a reflash won’t fix everything.

Tools for Hybrid Repair

What tools do I need to get into hybrid repair? That is a good question. It all depends on what you have now. What should a technically aware shop have at this time for equipment? A pair of Class O 1000 volt safety gloves with leather protectors, a good digital volt ohm meter (DVOM) rated CAT III @ 1000volts, a lab scope with that same rating, good technical information, and the proper scan tool. There are other hybrid related tools for specific models as well.

The Transition from Technician to Shop Owner: American Dream or Nightmare?

I call it the “bonehead cycle” of the Independent Repair Shop. Workers in the average Independent Auto Repair Shop are sick of being treated like dirt, working in poorly lit and ill-equipped conditions on junk cars that “just need to be fixed so they can get by.” The boss constantly complains that the workers are making more than he is and they ain’t making much.

Hybrid Air Conditioning Systems

November 14, 2008

By Craig Van Batenburg. In the beginning of hybrid car development the air conditioning systems were R143a systems that shared all the same components as a typical gasoline motor vehicle. The early hybrids were the Honda Insight, Civic Hybrid, Ford Escape, and Classis Prius (2001-2003). All hybrid A/C systems are really climate control. Only the Insight had A/C as an option, and it was a climate control system as well. Every other hybrid to date has factory climate control for some very important reasons.

What Is Your Audio IQ?

By Dave Hobbs. Car audio? Been more interested in R.P.M.s than in watts R.M.S.? Better rethink that philosophy with today’s factory car audio and entertainment systems.

We all know that look. We get it from customers from time to time.A guy drives up, parks out front and asks, “I’ve got a tail light out, can you put one in for me real quick?” You say, “Sure.” After it’s put in, you tell the guy, “All fixed and we checked all the other lights, too.
