Technology is Here to Stay
Heavy-Duty Diesels are essential for the well service industry. Some engine manufacturers design a diesel engine around their own capabilities. It is critical to specify the correct horsepower in the disgn stage so that the application adapts to the configuration and performance requirement. We design our heavy-duty equipment to deliver the performance you need from the equipment at your job site.
Engines manufacturers must meet U.S. Environmental Protection Agency (EPA) Tier 4 Final/European Union (EU) Stage IV emissions requirements. We require high power densities engines, delivering a high percent torque rise, with more horsepower to optimize performance.
Tier 4 Emission Standards
The Tier 4 emission standards—phased-in from 2008 through 2015—introduce substantial reductions of NOx (for engines above 56 kW) and PM (above 19 kW), as well as more stringent HC limits.
Environmental regulatory agencies focus on four types of engine emissions: carbon monoxide, hydrocarbons, nitrogen oxides, and particulate matter. As more focus is placed on health and environmental issues, governmental agencies throughout the world are enacting more stringent laws to reduce these emissions.
Because so many diesel engines are used in trucks, the U.S. Environmental Protection Agency and its counterparts in Europe and Japan first focused on setting emissions regulations for the on-road market. While the worldwide regulation of nonroad diesel equipment came later, the pace of cleanup and rate of improvement have been more aggressive for nonroad equipment than for on-road engines.
Non-road emissions reductions:
- Tier 3/Stage III A emissions regulations required a 40 percent reduction in NOx compared to Tier 2/Stage II.
- Interim Tier 4/Stage III B regulations require a 90 percent reduction in PM along with a 50 percent drop in NOx compared to Tier 3/Stage III A.
- Interim Tier 4/Stage III B and Final Tier 4/Stage IV must pass additional emissions tests including the steady-state 8-mode test (ISO 8178) and the rigorous nonroad transient cycle (NRTC) test.
- Final Tier 4/Stage IV regulations, which will be fully implemented by 2015, will maintain levels of PM and require an additional 80% reduction in Nox compared to Interim Tier 4/Stage III B.
Power Retrofit Technology
As local emissions regulations and programs continue to evolve to address the emissions of diesel powered well service equipment, more of the burden is being placed on equipment owners. Regulations can vary drastically across each region, equipment owners need to work with local regulatory authorities to determine how specific regulations affect them.
Due to the varying equipment and engine combinations across all horsepower ranges and applications, it is difficult to find after treatment solutions that are universally applicable. Let us help you determine if retrofit is right for your machines.
EPA regulations on emissions may be difficult to understand and differ from region to region
Always check with a qualified technician or OEM representative before changing or altering your equipment
Clean and efficient working equipment will preform better and save operating expense
Non compliant equipment could be subject to fines. Always check and verify.
The mission of EPA is to protect human health and the environment.
Our Environment Matters
- We have clean air, land and water;
- National efforts to reduce environmental risks are based on the best available scientific information;
- Federal laws protecting human health and the environment are administered and enforced fairly, effectively and as intended
- Environmental stewardship is integral to human health, economic growth, energy, transportation, agriculture, industry, and international trade, and these factors are similarly considered in establishing environmental policy
- All parts of society–communities, individuals, businesses, and state, local and tribal governments–have access to accurate information sufficient to effectively participate in managing human health and environmental risks
- Contaminated lands and toxic sites are cleaned up by potentially responsible parties and revitalized; and
- Chemicals in the marketplace are reviewed for safety.
