Manufacturing products also means transporting them, typically via truck. With new fuel economy standards coming and changes to diesel engine technology, a new engine oil specification is needed. In 2011, work began on a new diesel engine oil category for on-highway diesel engines called PC-11.
The new category is driven by changes in engine technology to meet emissions, renewable fuel and fuel economy standards for CO2 and other greenhouse gases. In addition, there have been changes in engine hardware that better represent new technology entering the marketplace since the last category was approved in 2006, and older hardware used in current engine testing is expected to become unavailable.
The new lubricant specification will have to meet the need of lower CO2 engines, while providing fuel economy benefits and no compromise in engine life or durability. PC-11 should provide improvements in oxidation stability, aeration benefits, shear stability, compatibility with biodiesel blends and protection from scuffing/adhesive wear.
The Engine Manufacturers Association recommends that the PC-11 category be split into two separate and distinct subcategories associated with fuel efficiency with corresponding performance levels:
Stay tuned: Communication on the new category and proper application of the different products will be forthcoming. Shell is working with others in the industry to help define and develop the new engine oil category. MT
According to Spraying Systems, its single-point AccuJet® Electrostatic Lube System can improve chain lubrication while reducing oil consumption and conveyor downtime. Capable of accommodating up to four electrostatic nozzles with an injector pump for each, it provides uniform lubrication of critical areas and eliminates oil mist, thus creating a safer work environment and minimizing cleanup and contamination potential. A dedicated control panel requires no programming, allowing easy installation via user I/O integrated with a PLC-controlled system.

Techno-Sommer’s Sharpshooter system addresses a number of lube challenges, including hard-to-reach lubrication points, expensive products that need to be precisely dispensed and the unacceptability of mist lubrication in a plant environment. Working off standard shop air at up to 90 psi, it can place a drop of lubricant at up to 1m away with pinpoint accuracy. A pressurized tank generates internal pressures up to 750 psi. When a pulse is generated, a fixed drop size is dispensed. Up to eight dispensing nozzles ranging in size from 5mm3 to 100mm3 can be attached to one tank. An extension hose of up to 2m in length allows for the dispensing nozzle to be placed around corners and in hard-to-reach spots.
