“Thank you for inquiring about our Foley Exhaust Purifiers.
If you have any questions please call us toll free at 800.233.6539 or 508.753.2979 or simply email us at Info@FoleyEngines.com.
Foley is different: we’re a three-generation, 98 year old family firm that wants to help.
Sincerely,
Dr. Diesel”
Foley Engines, founded 98 years ago in 1916, specializes in fuel management systems. These include fuel injection systems, carburetors for gas and liquid propane engines, Walker air seps, as well as exhaust scrubbers and purifiers. We have had a great deal of experience with our exhaust purifiers/scrubbers and have sold many units for use in building demolition projects, Boston’s Big Dig, California public works projects, building renovations at Brown University, etc. Both private sector companies such as the Hyster Forklift Co. (we are an OEM supplier to them), IBM (for their Armonk headquarters campus) and the Pfizer Corp. as well as such public sector organizations such as the Narragansett Electric Co, Pennsylvania Department of Transportation and the Los Angeles Water Resources Board use our exhaust scrubbers and purifiers. Many OEMs such as Hyster are now including our purifiers as standard equipment on new machines. All of the above companies and institutions like our cost effective solutions to their exhaust emission problems as well as our quick shipping from our US based company. We pride ourselves on shipping within 24 to 48 hours of the receipt of an order.
Below you will find 5 diesel exhaust gas emission reduction curves available for download. Emission reduction curves #1 to #3 (for CO, HC, and SOF) are optimized reduction curves, which were obtained, in in-house testing. Emission reduction curves #4 and #5 are part of an underground mining approval test. Emission reduction data table #6 represents mining approval test data. In a typical diesel exhaust gas purifier application the following average exhaust gas emission reductions can be expected:
| Carbon Monoxide (CO) | = | 80% – 90%+ |
| Hydrocarbons (HC) | = | 65% – 80% |
| Diesel Odor (HCHO) | = | 70% – 85% |
| Soluble Organics (SOF) | = | 70% – 85% |
| Diesel Particulate (DPM) | = | 20% – 39% |
These average exhaust gas emission reductions depend upon using a well maintained diesel engine operating with a moderate to heavy load while burning a low sulphur content diesel fuel. Whenever possible the purifier/scrubber should be mounted as close (within 12″ – 24″) to the engine’s exhaust manifold (or turbocharger) as possible.
Emission reduction curves #4 and #5 most accurately reflect the actual exhaust gas emission reductions, which can be expected in field tests. In curves #4 and #5 average carbon monoxide (CO) reductions were in the order of 93% to 97% while average hydrocarbon (HC) reductions were in the order of 65% to 78%.
Custom Purifiers/Mufflers
Custom made combination purifier/mufflers are designed to replace the stock OEM exhaust muffler. In other words, they install in place of the existing muffler. This allows the exhaust purifier to be situated in an ideal location in the exhaust system. This also allows the exhaust purifier to receive the maximum amount of exhaust heat energy in order to operate at the highest efficiency rating (80 to 90%). In the case of diesel powered equipment, the availability of exhaust heat energy is critical as low exhaust temperatures will cause the exhaust gas purifier to not function correctly.
In addition the installation time requirement of custom purifier/mufflers is minimal and comparable to installing a stock muffler. Custom purifier/mufflers are available in the following two basic forms:
| A) Catalytic Muffler | – A catalytic muffler is very similar in appearance to the stock OEM muffler with the exception that the muffler body is made of stainless steel and a catalytic purifier core is added. The stock OEM muffler is removed and the catalytic muffler is installed in its place. Currently we offer catalytic mufflers for Melroe Bobcat, Case, New Holland, Gehl, Genie, CAT, Kubota, Komatsu, Wisconsin, Honda, John Deere, Ingersol Rand, Wagner, Jarvis Clark and a variety of other construction, mining and tunneling equipment. |
| B) Catalytic Purifier Kit | – A catalytic purifier kit is similar in appearance to a stock OEM exhaust flex-pipe or exhaust pipe located in the exhaust system before the exhaust muffler. The kit incorporates a catalytic purifier core in the exhaust pipe configuration. The kit is a direct replacement for the stock OEM exhaust component. The stock OEM exhaust component is removed and the kit is installed in its place. Currently we offer kits for Melroe Bobcat, Mustang, Thomas Skid Steers, Case, and a variety of other construction, mining and tunneling equipment. |
To better clarify curves #4 and #5, the following symbols are defined as:
| COpd |
=
|
Carbon Monoxide before purifier |
| COzd |
=
|
Carbon Monoxide after purifier |
| CHpd |
=
|
Hydrocarbon before purifier |
| CHzd |
=
|
Hydrocarbon after purifier |
| Td |
=
|
Exhaust gas temperature (in C) before purifier. |
In emission reduction table #6 (which is a 8 mode steady state test) maximum CO reduction was 95%, maximum HC reduction was 62% and maximum DPM reduction was 39%.
