The circuit has been constructed to provide an in-circuit system that will test the integrity of electronic components such as Silicon Controlled Rectifiers, diodes, and PNP or NPN transistors. 4093 – ...

The circuit in the diagram is a very handy tool for rapidly checking all kinds of thyristor (SCR, triac, …). In case of a triac, all four quadrants are tested, which is done with S3, while in case of ...

So it‘s a little after six in the a.m. when Jimmie Kissling and I get rolling down the still-dark rural roads for the first job of the day - getting a load of asphalt “binder” for a parking lot ...

Daimler Trucks North America (DTNA) and the Volvo Group have responded to Navistar’s recent studies on Selective Catalytic Reduction (SCR) relating to fluid efficiency and emissions. Here is DTNA’s ...

Navistar is suing to force the Environmental Protection Agency to go back and re-test SCR engines for compliance with clean air standards and other aspects of the 2010 emission rule. In the suit, ...

Call it pre-need planning. When Detroit Diesel rolled out its DD15 engine in October 2007, the company said it was a clean-sheet design, birthed EPA-'07-compliant and 100 percent ready for EPA-2010 .

Green Granite with its 2010 SCR diesel is owned by Mack and was loaned to Haines & Kibblehouse for testing. It has worked well and fuel economy is encouraging. MP7-405 Maxidyne diesel looks like a ...
