Directions: More Diesels Heading Down The Pipeline
It may be a good idea to have some of your techs become ASE certified in diesel engine diagnostics, which you can market to your diesel-driving customers.
Tech Feature: Venturing Into GM Duramax Diesel Service
Back in the 1990s, GM wasn’t making too many waves in the diesel truck market. The 6.2L and 6.5L engines had been around for sometime, but they were no match for the release of the Cummins 6BT in the Dodge truck in 1989 and the Ford Powerstroke in 1994.
Obama Administration Finalizes 54.5 MPG Fuel Efficiency Standards
In total, the Administration’s national program to improve fuel economy and reduce greenhouse gas emissions will save consumers more than $1.7 trillion at the gas pump and reduce U.S. oil consumption by 12 billion barrels.
Book Report: Tips for Ford Power Stroke Service and Rebuilds
The book covers the vast majority of Power Stroke diesel engines on the road, and gives you the full story on their design.
Tech Talk – Engine Innovations to Reach Government Fuel Standards
In recent years, the primary driving force behind engine innovation has been the never-ending quest for better fuel economy with little or no sacrifice in performance. Government regulations and rising fuel prices are forcing automakers to develop new technologies and powertrains that squeeze more power out of every drop of fuel while producing less pollution and greenhouse gas (carbon dioxide) emissions.
Getting Stoked to Service the 6.0L Power Stroke
If there were one engine that plagues the mid-size diesel world, you would have to say that it is the 6.0L Power Stroke. The 6.0L came into existence because the EPA demanded tighter emissions laws for diesel engines. Even though the 7.3L was branded as the reliable workhorse for Ford, it would never be able to pass the tighter emissions laws that were going to come into effect for 2004.
Service Solutions: The ‘CKP’ Script
The signal of the position or rotation speed of the crankshaft position sensor (CKP) contains a lot of information about the engine. When the engine is operating, the engine cylinders push on the crankshaft journal. This is why the crankshaft briefly accelerates after top dead center (TDC) on the expansion (or combustion) stroke. If the fuel did not ignite in the cylinder there would no acceleration.
Clean Diesel Surge Offers Diagnostic and Repair Opportunities for the Aftermarket
There’s a bright future for the latest generation of clean diesel cars and trucks, thanks to common rail high-pressure, direct-injection systems with sophisticated electronic controls that have transformed today’s diesels into clean-running, quiet and powerful power plants. As these vehicles come out of warranty, it will create new diagnostic and repair opportunities for the aftermarket.
Diesel Engine Glow Plugs: Not Just For Starting Anymore
Since diesel engines ignite by using the heat of combustion, they usually need help when the climate changes to the cold of winter.
Report Card — ‘Defender’ of the Land
According to Land Rover designers, replacing the iconic Defender is one of the biggest challenges in the automotive design world
Delphi Offers Technician Training Programs to Support Ongoing Education in the Vehicle Electronics Reality
Delphi’s various training initiatives prepare technicians for future success; Delphi Dream Shop giveaway also provides for one technician the foundation for growth.
Tech Tip: Ford 7.3L Powerstroke ‘Cackle’ (Noisy) Injector
Some vehicles may experience a misfire or “cackle.” The injectors in the 7.3L diesel run off of the high-pressure engine oil pump. The number 8 injector is the farthest away from the oil pump, causing a filling problem, which may result in a misfire. Ford replaced the number 8 injector in some vehicles as needed with a different injector to solve the problem.
