Engine Notebook: Cummins technology for 2007 and Tier 3
The first U.S. emissions regulations for on-highway diesels arrived in 1973. The first U.S. emissions regulations for mobile off-highway diesels arrived in 1996, a lag of 23 years. The gap between on- and off-highway implementation has now narrowed to three or four years. The goal is to have all diesel applications coordinated by 2015 or […]

Maintenance/Management: Dealing with dust
Heavy equipment engines may be massive and powerful, but all it takes is a teaspoon of dust to ruin one. Silica, the primary ingredient in dust, is highly abrasive and acts like a lapping compound – polishing your piston rings, valves, cams and crankshafts and sandblasting your fuel injectors or any moving part with tight […]

Engine Notebook: Cat gets ACERT-ive
A key goal in Caterpillar’s development of ACERT technology was to provide commonality – one basic strategy to meet in-place and upcoming emissions standards for both on- and off-highway applications. It’s working. The same basic design that satisfies current Tier 3 nonroad standards will be the platform on which Tier 4 nonroad engines will be […]

Application Tips: Motor graders
Since you’ll probably hang onto a motor grader for 10 to 15 years, get a good handle on the average size of your jobs and how much dirt you’ll be moving before making a purchase. If your projects are usually along the lines of one-acre parking lots, a small, 80- to 150-horsepower grader will work, […]
