Emissions Solutions

Helping your business reach the next level

Keep your business competitive with Caterpillar® Emissions Solutions from Patten Cat. Many local, state, and regional regulatory bodies are passing new laws that mandate emissions compliance. If your equipment doesn’t meet emission standards, it can cost you money, time, and lost opportunities.

Patten Cat Emission Solutions can help you do five things:

  1. Keep compliance costs to a minimum
  2. Limit downtime while retrofits are performed
  3. Extend the life of your machines
  4. Protect your current business
  5. Prepare for future opportunities

Let us help you find your perfect Emissions Solutions

All Caterpillar Emissions Solutions are customized to your needs. They are tailored for the regulations in your work area, the type of machines you own, and in some cases, the type of work you do. To help you explore your options, Patten will need the following information to help you become compliant:

There are a number of Caterpillar emissions solutions to choose from. The best option (or mix) for you depends on your equipment, applications, local emissions requirements and more. Recommended solutions may include:

Engine Repower: Replacing your existing engine with a new, lower-emissions engine

Engine Upgrade Group: Upgrading an existing engine using new components and parts

Aftertreatment: Treating exhaust gases to reduce harmful emissions

Working with the Caterpillar Emissions Solutions group, Patten can provide everything you need to achieve and maintain full regulatory compliance.

Emission Solutions for all Cat® Equipment

Off-Road Machines

Caterpillar emission retrofits for mobile off-road machines fall into two categories:

Engine Repower Solutions replace your entire engine with a new, lower-emissions Cat engine. Engine repower solutions are available for all classes of Cat and competitive diesel engines. To save downtime, consider doing an Engine Repower at the same time as another major replacement or overhaul.

Engine Upgrade Group Solutions utilize your current engine core. A range of upgrades replace existing parts with new components that deliver lower emissions. This can be an effective, lower-cost option in many cases. Performing an Engine Upgrade during engine overhaul saves downtime and may help reduce overall costs.

On-Highway Vehicles

Two types of Caterpillar Emissions Solutions are available for on-highway trucks and buses: oxidation catalysts and particulate filters.

Oxidation Catalysts create a chemical reaction with exhaust gases as they pass through the catalyst material. This reaction coverts a large portion of carbon monoxide, hydrocarbons and other emissions into carbon dioxide and water. Available for diesel and natural gas engines, Cat Oxidation Catalysts come with a 1-year/8,000-hour warranty.

Diesel Particulate Solutions use special filters to reduce particulate matter (PM), carbon monoxide and hydrocarbon emissions. Exhaust backpressure is reduced through passive regeneration, a process that automatically removes particulate buildup. Available only for diesel engines, Cat Diesel Particulate solutions include a diagnostic module for backpressure and exhaust temperature monitoring. The type of solution appropriate for a specific application depends on the configuration of the vehicles’ exhaust systems and the specific emissions targeted by the applicable emissions regulations.

Stationary and Portable Power Equipment

Caterpillar emissions retrofits for your stationary equipment are tailored for Caterpillar diesel and gas engines. Solutions can also be customized for many non-Cat engine applications. Three types of Cat Aftertreatment retrofits are available for stationary engines:

Oxidation Catalysts create a chemical reaction with exhaust gases as they pass through the catalyst material. This reaction converts a large portion of carbon monoxide, hydrocarbons and other emissions into carbon dioxide and water. Available for diesel and natural gas engines, Cat Oxidation Catalysts come with a 1-year/8,000-hour warranty.

Selective Catalytic Reduction is the only Aftertreatment effective for reducing emissions of nitrous oxides (NOx). By injecting urea (a non-hazardous form of ammonia) into the hot exhaust stream, this process reduces most exhaust emissions to harmless nitrogen and water vapor. Available for diesel and natural gas engines, Cat Selective Catalytic reduction is warranted for 1 year/8,000-hours. It requires limited maintenance only during normal engine service routines.

Diesel Particulate Solutions use special filters to reduce particulate matter (PM), carbon monoxide and hydrocarbon emissions. Exhaust backpressure is reduced through passive regeneration, a process that automatically removes particulate buildup. Available only for diesel engines, Cat Diesel Particulate solutions include a diagnostic module for backpressure and exhaust temperature monitoring.
