Automakers Give Disregarded Diesels A Second Look

Automakers are working in many ways to meet new tough fuel economy standards — both national goals set by the Obama administration and state standards, like California's new rules passed Friday requiring that 15 percent of new vehicles sold in the state must produce little or no air pollution by 2025.

But carmakers aren't just turning to new technologies like hybrid and electric cars. Many in the auto industry are taking a second look at an old technology: the diesel engine.

University of Michigan professor Margaret Wooldridge explains how an engine running on diesel fuel differs from a gasoline-powered engine.

"The strategy for introducing the fuel into the [diesel] engine is you inject it directly into the engine," she says. "For a gasoline engine it needs a spark plug to ignite the fuel; a diesel engine doesn't have a spark plug."

Rules For CNC Machine Purchase And Repair

! A major exception to this rule is the purchase of a CNC machine or other item you add to that. You really get what you pay in CNC equipment - new or used.

If you do not pay in advance, you pay later. Again and again. And you yourself kicked in the a-whenever you call the type of repair.

Economical CNC machines have less power and therefore the pin stalls more often.They have restricted linear guides, ball screws ball less, no oil cooler on the shaft, bearings less in line, lock less secure and, above all, they are much less rigid, which is the leading cause of CNC machine to crush and subsequent cases.

Finally, even the best the problems experienced CNC machines. Most machinists and operators are not trained or equipped to repair the equipment CNC machining.For repairs, you will need a repair shop in the electronics industry have known, at least in troubleshooting, alarm codes, and servo drive problems, electrical faults, troubleshooting PLC ladder , problems with DC motor, the load axis or binding, the solenoid / relay / contact tests, feeding problems, the axis of brake problems, problems of Chuck, the problems of relay board, the Setup lighting, control and setting issues, hydraulic and pneumatic door and safety interlocks....
