Diesel engines are a highly efficient and durable choice to power vehicles such as trucks, ships, locomotives and equipment for farming, construction and mining.  All types of fuel burned in engines produce emissions that are released into the environment.  They can contribute to air pollution which can have environmental and health effects.  In an effort to reduce the amount of air pollution that is released from diesel fuel burning engines, the EPA has standards in place to reduce pollutants, air toxics and other detrimental emissions.

The amount of pollution that is produced when diesel fuel is burned in an engine is linked to the amount of sulfur that is in diesel fuel.  The higher the level of sulfur in the diesel, the higher the amount of pollutants that are released into the air when the diesel is burned.  This air pollution can than lead to health issues such as heart and lung disease, as well as causing damage to the environment by damaging plants, crops and water resources.

To decrease the amount of pollution that is released form diesel emissions the EPA has created a set of standards that all diesel fuel has to meet. Vehicles that travel on roads like cars and trucks must use an ultra-low sulfur diesel (ULSD) that is a 15 ppm sulfur specification.  As of 2014 all nonroad, locomotive and marine diesel fuel used must also be ULSD.  As of 2015 large marine diesel engines, or category 3 engines, operating with the U.S. Coast Guard established Emission Control Areas must generally use diesel fuel with 1,000 ppm sulfur or less.  These standards have helped to reduce harmful pollutants from diesel emission into the environment.

At Central Diesel we offer a variety of different diesel engines.  The diesel engines we offer also meet a variety of EPA and state certifications such as U. S. EPA Non-road Tier 3 (with letter of exemption from EPA), U. S. EPA Non-road Tier 3 for ratings 56 kW and higher (with letter of exemption from the EPA), U.S. EPA Non Road Tier 4, U. S. EPA Non-road Tier 4 Interim for ratings less than 56 kW, and California ARB Non-road. When it comes to environmental concerns that effect global warming (greenhouse gases, carbon footprint, etc.) the diesel engine leads all internal combustion engines in protecting our planet today and into the near future.  For more information and engine specs, take a look at our website.
