Smaller is Better: T4F engines under 75 hp don’t sacrifice torque, require less maintenance
With the emergence of the Tier 4 Final era, most of the big changes in diesel engines have been on those above 75 horsepower. They required new emissions reduction systems using selective catalytic reduction (SCR) and diesel exhaust fluid (DEF). But in most cases, engines below 75 horsepower hit their air quality targets by upgrades […]

New T4F engines with 74+ hp demand a thorough maintenance plan
New engines above 74 horsepower come with sophisticated exhaust aftertreatment technology that demands preparation and protocols. The day you take delivery of a new machine is one of excitement and celebration. But this year, and in the future, the thrill of new iron should be tempered with a thorough plan to manage the new exhaust […]

Engine Repowers: The complicated business of putting a new diesel in an old machine
It used to be easy to replace an engine in an older piece of diesel-powered equipment in the era before emissions controls. In many cases today, that process doesn’t start with an engine hoist, but instead requires permission from air quality regulators before you touch a wrench. That’s because with each new iteration of diesel […]

Beyond Tier 4, how else have OEMs been improving wheel loaders since resolving after treatment?
So what have wheel loader manufacturers been working on since Tier 4 engines and after treatment have been resolved? We asked specifically about hydraulics, electronics and components. How have these areas been improved and how does that translate to value for the customer? Hydraulics get efficient In the past, manufacturers used fixed-displacement pumps. These run the same flow and same pressure […]

JCB unveils Tier 4 Final Ecomax engines at Bauma, calls them “one-can” solution
JCB says its Tier 4 Final Ecomax engines will offer a “one-can” solution, avoiding the use of both a diesel particulate filter (DPF) and a diesel oxidation catalyst (DOC). “The SCR unit is so compact that it can in many cases take the place of a current exhaust system and fit into existing machine configurations,” […]
