Real Solutions for Emissions Control
Cummins has been a leader in the development of engine and emission reduction technologies for 90 years. Cummins Emission Solutions (CES) is a leader in catalytic exhaust products, with over 2.0 million units in service. Our 30 years experience in exhaust engineering and manufacturing, and our partnerships with the leading component suppliers provide a high level of dependability and performance.

In addition to designing new technology into our current engine offering, we also offer retrofit solutions for existing engines. Because of the durability and reliability of diesel engines, they can last for decades, continuing to produce the same level of emissions as when they were new. To improve air quality and protect public health in recent years, EPA and CARB emission level requirements for new engines have significantly been reduced. This has also prompted the clean up of older engines by using various retrofit devices, using alternative fuels, or by replacing or repowering the engines.

Exhaust Gas Recirculation
In 2002, Cummins began using Exhaust Gas Recirculation (EGR) and our patented Variable Geometry Turbocharger (VG Turbo) to help reduce emissions, and comply with the stringent California Air Resource Board’s (CARB) emission standards. By re-routing some of the exhaust gases and introducing it back into the intake system, combustion temperatures can be reduced, along with smog and ozone producing NOx emissions.

Aftertreatment Devices
Exhaust aftertreatment retrofit devices such as Diesel Oxidation Catalyst and Diesel Particulate Filters can reduce harmful engine exhaust emissions. CARB Verified Level 3 devices are considered the Best Available Control Technology (BACT). Cummins Cal Pacific can provide proven, cost effective, active and passive retrofit technologies for your on road and off road engines.

Engine Repower Options
An effective way to reduce the emissions from existing off-highway equipment or on-highway vehicles is to repower the engine with a newer, cleaner one meeting 2007 or Tier 2 or Tier 3 emission standards. Cummins offers several options to repower trucks, boats, and construction and industrial equipment.

All Cummins engines sold in CA meet the California Air Resource Board’s (CARB) and US EPA’s requirements. Most all on highway engines utilize a Cummins Particulate Filter (CPF) to reduce Particulate Matter (PM) emissions to .01g/bhp-hr, and all off road certified engines (up to 750 Hp) meet the Tier 3 emissions level.

• ReCon engines are a proven, reliable and cost effective way to extend the life of equipment, while meeting or beating its original emissions requirements.
• New engine repowers ensure that the equipment’s emissions are the cleanest possible for its class, and it’s a reliable, warranted engine guaranteed to meet the current emissions standards for 2007 or Tier 3.
• Alternative fuel engine repower is another great way to reduce emissions, and keep your fuel costs in check. Cummins offers engines that operate on Compressed Natural Gas (CNG), Liquid Natural Gas (LNG), and Liquefied Petroleum Gas (LPG). Cummins Westport’s natural gas ISL G engine is clean enough to meet the 2010 emissions levels (0.2g/bhp-hr NOx) today.
