Back in your father’s day, compact equipment ran on diesel fuel that was cheaper, easier to store and performed better in cold weather. Fuel systems were much simpler and less sensitive to contaminants. Parts were relatively inexpensive to replace, and there was little concern about component deterioration or diesel fuel’s effect on emissions.
A machine operator’s measure of producing good power was the amount of visible black smoke — the more, the better. Despite the harmful effects of diesel exhaust, there were few incentives for the industry to pursue cleaner fuel.
Understanding how today’s diesel fuel is different, and how it relates to advanced engines, is crucial to everyone’s shared success.
1. All Tier 4 engines require ULSD
In 2010, ultra-low sulfur diesel (ULSD) became the requirement for all U.S. diesel engines. It ushered in a new era of fuel chemistry that impacts all compact equipment manufacturers regardless of their Tier 4 engine designs.
Many diesel engines use high-pressure common-rail (HPCR) technology. In order to burn cleaner, hotter and more efficiently, these systems use extremely precise mechanisms that demand clean fuel for component longevity and to maintain emissions standards set by the Environmental Protection Agency.
