Cummins has 1500 Fleetguard air filter designs for engines
Plugged air filters reduce engine performance, create higher fuel consumption, increase exhaust fumes and are harmful to the environment. . To properly perform its function of reducing wear and extending engine life, the air filter must filter 100% of the pre-combustion air and remove as much contaminant of any and every particle size as it can to a very high final efficiency. ******With a range of over 1,500 different air filtration products from clamps to air housings to “state-of-the-art” air filters, Fleetguard Heavy Duty Air Filtration, covers all the needs for air intake systems. Fleetguard Visibowl™ Pre-Cleaners and highly efficient Fleetguard pre-cleaner ™ self cleaning Pre-cleaners are strongly recommended for construction, mining, farming, forestry and other segments where operating conditions are severe.

In 2016 MEACa wrote a position statement to assert the desirability of emission controls for the Bureau of Ocean Energy Management’s (BOEM) request for public comments on its proposed rule titled “Air Quality Control, Reporting, and Compliance.” **********A survey of MECA members estimates that there are over 800 stationary diesel engines in the U.S. that currently use DPFs. The vast majority (90%) of these engines are in-use emergency standby engines, with the rest being prime stationary genset engines. Some states with ozone nonattainment areas require DPF’s to be installed on engines as a result of New Source Review (NSR) or Best Available Control Technology (BACT)/Lowest Achievable Emission Rate (LAER) analysis. In those cases, DPFs along with SCR have been required on emergency diesel engines. Furthermore, many states require emergency diesel engines, that are also used in demand response programs for power peak shaving, to install DPF as well as SCR control devices. There are at least five MECA member companies that have experience with the installation of DPF retrofits on emergency standby diesel engines. One MECA member company has had extensive experience with the retrofit of stationary diesel engines in Taiwan. Power outages are frequent in Taiwan, so standby generators used for emergency back-up power are an important part of the country’s infrastructure. DPFs have been successfully installed on these generators. For example, Taiwan Semiconductor Manufacturing installed DPFs on 14 emergency standby generators (2 MW engines) in 2001, which has resulted in a greater than 90 percent reduction in PM.

Kohler Recommends Approach to Sizing Data Center Engines
Kohler weighs in on engine sizing and emission control based on two sets of criteria. One is to insure adequate power is available and the other is to meet EPA emission limits, Kohler makes a case as to why specifying a continuous rating (as the Uptime Institute recommends) for generators in the data-center industry is unnecessary. First, consider that the main purpose of the ISO 8528-1 ratings standard is to classify the type of application for which a generator rating is to be used. In nearly every case, data centers are standby (emergency) applications. The generator is not the primary power source; it is used to back up a reliable utility, or in the case of Tier III and Tier IV data centers, multiple independent utilities. The only exceptions are areas where there are no utilities, and the generator is used as prime power. **********The second set of criteria determine the emission control requirements A stationary “emergency” application is where the generator set remains in one location for 12 months or longer, is the secondary power source when the utility (primary power source) fails, and annual maintenance and readiness testing is less than 100 hours. The term “emergency” refers to the use of the engine when an emergency occurs (utility fails). In virtually all cases, these applications will have a “standby” generator rating. Remember that standby-rated generators can run an unlimited number of hours with varying load during the utility outage. Stationary emergency applications in the U.S. require diesel engines that are EPA-certified to Tier 3 if their power output is between 50 BHP (40 kW) and 560 BHP (500 kW), or certified to Tier 2 if their power output is above 560 BHP (500 kW). A stationary “non-emergency” application is where the generator set is either the primary power source or a secondary power source connected to an unreliable utility with planned high hours of annual usage. Additionally, using it for peak shaving, interruptible rate, or any financial arrangement with a utility qualifies it as a non-emergency application. Non-emergency applications may use prime, limited running time or continuous ratings. Non-emergency applications in the U.S. require EPA-certified Tier 4 diesel engines, which are designed for lower emissions and are much more expensive than their stationary emergency counterparts at the Tier 2 and Tier 3 levels. A non-road application is where the generator set is in more than one location within a 12-month period. Typical applications are mobile, rental or containerized generator sets. Non-road applications may use prime, limited running time or continuous ratings. These applications require EPA-certified Tier 4 diesel engines.********** Todd Matte Manager - Corporate Accounts Project Management Group of Kohler was the author of this 2015 document.

The Electrical Generating Systems Association (EGSA) is the world’s largest organization exclusively dedicated to on-site power generation. It has rated silencers into 7 classes. Generally silencers are one of or a combination of three types of devices: 1.Reactive silencers, often referred to as "chamber" silencers, generally have their peak DIL in the 63 or 125 Hz OBCF 2.Absorptive silencers, often referred to as "packed" silencers, generally are most effective in the 250 Hz through 8 KHz OBCFs. 3.Resonators are generally specifically designed to have an effective DIL over a very narrow range, usually no more than a single octave. Reactive Silencers are thought of as Exhaust Silencers and their performance is usually based on a "typical" Exhaust Gas Temperature (EGT) value. Generally Absorptive Silencers are applied as intake silencers to best control the high frequency content of modern high speed turbocharged engines. When absorptive are applied in combination with a reactive silencer, as is becoming more common with higher speed multi-cylinder engines and requirements for noise reduction as an A-Weighted value are becoming more demanding, the performance of these must be adjusted for size and the longer wavelengths for specific frequencies in the exhaust system. Generally a Resonator is designed for a specific requirement.
