What type of fuel is primarily used in DTNA diesel engines?

The primary fuel used in DTNA diesel engines is ultra-low sulfur diesel (ULSD). This type of fuel is specifically formulated to meet stringent emissions regulations aimed at reducing harmful pollutants. ULSD contains significantly lower levels of sulfur compared to traditional diesel fuels, which helps in minimizing the amount of sulfur dioxide released into the atmosphere during combustion.

Using ULSD is critical for modern diesel engines, particularly those equipped with advanced emission control technologies like diesel particulate filters (DPFs) and selective catalytic reduction (SCR) systems. These technologies are designed to work efficiently with ULSD to meet environmental standards while maintaining engine performance and fuel efficiency.

In contrast, regular diesel and high sulfur diesel do not meet the current emissions standards and can produce higher levels of pollutants, making them unsuitable for use in compliant diesel engines. Biodiesel can be blended with ULSD for certain applications, but it is not the primary fuel for DTNA diesel engines; its use also depends on specific engine compatibility and regulations.
