In December 2015, the Federal Motor Carrier Safety Administration (FMCSA) passed a mandate requiring electronic logging devices (ELDs) to be used in all commercial motor vehicles where paper driver logs are currently required.
Not long after U.S. engine manufacturers finished patting themselves on the back for a job well done meeting Tier 4/Stage IV emissions regulations in 2015, those in the know naturally started asking "what's next?".
Trucking is a dirty business, in a physical sense. Commercial trucking burns millions of gallons of diesel a year, and that in turn means pollution in the form of greenhouse gases, or GHG. Now the Environmental Protection Agency is taking steps to cut down the GHG emissions across the board, and it will change the trucking industry in some surprising ways.
Any product can claim to be "safe" or "waterproof," but when you're purchasing for a specific application, you need hard data, not vague promises. That's where ingress protection codes, or IP codes, come into play. Here's what they do, what they mean, and how to use them when purchasing.
Fundamentally, RoHS restricts six substances: 4 heavy metals (lead, cadmium, mercury, hexavalent chromium) and two flame-retardants (PBBs and PBDEs). The concentration limits for all these substances is .1% of any homogenous material – except for cadmium (.01%). Despite the fact that RoHS only applies to electrical and electronic equipment (EEE ) placed on the EU market, it has been highly influential in pushing similar (but NOT identical) requirements in many other geographies.
The IP Code, International Protection Marking, IEC standard 60529, sometimes interpreted as Ingress Protection Marking, classifies and rates the degree of protection provided against intrusion, dust, accidental contact, and water by mechanical casings and electrical enclosures.
New diesel engines will be cleaner than ever, the results of a decade long evolution in technology.January 1, 2014, was a bellwether day for off-road diesel engines, when new regulations went into effect requiring the majority of diesel engines sold in the U.S., Japan and most of Europe to begin meeting the strictest exhaust emissions standards in history.
