Worldwide and nationwide, emission requirements are changing quickly. There are new and existing regulations, which can become an obstacle when undertaking a new project. If equipment doesn’t meet emissions standards, it can cost time, money and lost opportunities. But achieving regulatory compliance does not have to mean sacrificing productivity or uptime.
Whether updating equipment to comply with government regulations, meet a bid specification or to “go green,” Foley provides emissions solutions for any engine in trucks, buses, construction machines, marine vessels, power generation systems, or any other type of industrial equipment. Its emissions reduction technologies will enable compliance with the strict local, state and federal emissions standards. It also provides on and off-road interpretation of federal, state and local emissions regulations for all types of applications.
Foley Incorporated provides the following emissions reduction technologies:
Closed Crankcase Ventilation Systems (CCVS)
A closed crankcase ventilation system eliminates the crankcase emissions from a diesel engine and improves the air quality around the engine, such as inside a school bus or in the engine room. This technology connects to the existing engine blow-by tube and reduces the build up of engine oil in the engine compartment and the exposure to particulate matter emissions, according to Foley.
Diesel Particulate Filter (DPF)
A diesel particulate filter is more effective in reducing particulate matter emissions from diesel engines than a diesel oxidation catalyst (DOC). This technology typically reduces more than 85 percent of the particulate matter (PM) emissions and significantly reduces hydrocarbons (HC) and carbon monoxide (CO) emissions.
• “Passive” regeneration. Occurs when the exhaust temperatures are hot enough to sufficiently raise the temperature of the filter element during the normal duty cycle. Metal-based catalysts applied to the filter alter the combustion chemistry and reduce the exhaust temperature needed for passive regeneration.
• “Active” regeneration. Must be used when the engine exhaust temperature is not hot enough to initiate combustion of the collected PM, and requires an additional heat source to sufficiently raise the temperature of the filter element. The minimum frequency of regeneration is determined by the rate of PM build-up and is generally once per day or shift.
Flow Through Diesel Particulate Filters (FTF)
Flow through diesel particulate filters are effective at capturing a portion of the unburned carbon particles or particulate matter (PM) from diesel engines. These filters consist of a corrugated metallic honeycomb substrate coated with a platinum based catalyst. This technology typically reduced 50 to 70 percent of the particulate matter emissions and significantly reduces hydrocarbons and carbon monoxide emissions and requires no additional maintenance. These filters have been used primarily on applications that a safety hazard can result if the engine is shut down for unscheduled maintenance, such as a crane.
Selective Catalytic Reduction (SCR)
Selective catalytic reduction (SCR) system is used primarily for stationary gas and diesel engine applications. This technology offers a durable and reliable process to reduce nitrogen oxides (NOx) emissions from any engine with no impact on engine performance, according to Foley.
On-Highway Truck and Bus Solutions
Emission reduction technology is available for all on-highway truck and bus applications regardless of engine, truck or bus manufacture. The technologies that can be used for emissions retrofits are diesel oxidation catalysts, diesel particulate filters or a closed crankcase ventilation system. These retrofits are designed to be direct muffler replacements on any bus or truck and are sized with respect to the engine displacement and power output.
Emissions solutions also are available for all types of construction equipment powered by diesel engines. These retrofit solutions can help meet today’s strict local emissions requirements. The retrofits for construction equipment can consist of repowering the machine with a newer emissions compliant engine, or adding an after treatment such as a diesel particulate filter.
Emissions retrofit solutions also are available for all power systems engines. Power systems engines are used in marine electric power generation and other industrial applications. The emissions reduction technologies used for these engines are similar to the emissions solutions used for construction equipment, trucks and buses. The end result is lower airborne emissions proving, once again, that retrofit technology is a cost-effective solution to reduce emissions for older engines that were not designed to meet today’s tighter emissions standards, according to Foley.
Foley has an in-house specialist, Aaron Israel, who works to develop an efficient plan to achieve the targeted emissions levels and immediate retrofit requirements. Israel has 10 years of experience in emission solutions consulting, engineering and product development.
As emissions specialist, Israel’s role will be to provide emissions regulatory interpretation support to Foley’s construction, power systems, on-highway and rental services divisions. He also will provide application and engineering support to our sales organization for emissions retrofit solutions to meet local air quality regulations for new and existing engines and equipment.
Foley is also the only authorized construction equipment dealer on New Jersey State Diesel Retrofit Device and Installation contract T-2541. Servicing Northern and Central N.J., Staten Island and Bermuda, it will partner with you to ensure you meet emissions compliance requirements.
