  1. Diesel Emissions Reduction Act Helps Improve Air Quality

    Leave a Comment

    For heavy duty vehicles, diesel engines are the best choice due to their durability and efficiency. In past blogs we’ve looked at the steps that have been taken to make diesel engines more environmentally friendly with the shift to clean diesel engines. This resulted in standards which were designed to cut the allowable levels of sulfur in diesel fuel by 97%. To continue the shift to clean diesel engines, recently the Diesel Emissions Reduction Act (DERA) was passed.

    Diesel Emissions Reduction Act

    The Diesel Emissions Reduction Act was created by the U.S. Environmental Protection Agency to allow for significant air quality improvements. Most recently it was announced that the EPA would be awarding $7.7 million to replace or retrofit 401 older diesel school busses under 27 states under DERA. The goal of this is to finance the replacement of older diesel buses with newer and more efficient technology.

    DERA has been vital over the years to make sure old, harmful to the environment diesel engines are replaced and upgraded to environmentally friendly engines. According to a 2016 EPA report, more than 73,000 older diesel powered engines were upgraded or replaced between 2008 and 2013. The school bus rebate program made up a large number of these replacements, as school districts are able to obtain funds to upgrade their diesel engine powered school bus fleet. With the advancement in technology available, it is important for the environment to replace old diesel engines, with the new available clean tech diesel engines.

    Here at Central Diesel Inc. we are a distributor of clean tech diesel engines that are used for numerous applications and industries including the marine, construction, mining, transportation, and agriculture industries. With a growing inventory of diesel engines from brands such as Deutz, Mitsubishi, Kubota, and Zenith Power Products among many others, we can meet all your clean diesel engine replacement needs.

  2. The Shift to Clean Diesel Engines

    Pollution from engine emissions has always been a concern as heavy duty trucks became the go to transportation option for freight and cargo shipments. In 2000, the U.S. Environmental Protection Agency recognized the dangers emissions from heavy-duty trucks and buses could cause and developed rules and regulations to limit them.  These new standards were designed to cut the allowable levels of sulfur in diesel fuel by 97% by 2010.  By 2007, all heavy-duty diesel trucks sold had to have particulate emissions levels of no more than 0.01 grams per brake horsepower hour.

    Here in 2016 we are witnessing the results of these regulations.  According to the Diesel Technology Forum (DTF) more than 40% or about 4 million of the 9.5 million medium and large diesel trucks on the road have shifted over to newer technology clean diesel engines.  These trucks have particulate emissions levels near zero, which is resulting in clean air benefits being felt all over the U.S.  These new engines also are benefiting truckers by showing 3-5% improvements in fuel economy from the older style diesel engines.

    The Rise of the New Clean Diesel Engines: 

    In Indiana, Utah, Oklahoma and Texas, more than 50% of all trucks boast the new recommended clean diesel engine technology. California and Oregon are close behind with growing numbers of newer diesel truck registrations.  It is evident that the engine has achieved something almost impossible – it has satisfied the mandates of the Environment Protection Agency and has managed to incentivize its adoption through enhanced fuel efficiency. The future of emissions pollution control in the US looks bright.

  3. Diesel Fuel Emissions Regulations

    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.
