Recent Development in Heavy Duty Engine Air Filtration and the Role of Nanofiber Filter Media
The development of an engine air filter is based on filter performance requirements, vehicle’s operational environment, available space, filter media properties, and production technology. The design process includes analyses of theoretical and empirical models describing filter media performance and aerosol flow in filter housings and through filter elements. Filter media are carefully selected based upon these models and simplified laboratory tests. The filter element design is evaluated in great detail through a series of laboratory and field experiments.

Nanofiber Media Performance in Application to Motor Vehicle Air Filtration
The function of air filtration systems in motor vehicles is to improve air quality and cleanliness in car interior, control the respirable particle concentration in the operator’s cabin, and reduce the dust concentration in the engine intake air to an acceptable level. In these applications, limited space is available for the air filtration systems. Therefore, filters are designed in smaller packages, resulting in higher aerosol velocities through the filters. Such high aerosol velocities may cause dust reentrainment leading to an increase in the amount of dust penetrating the filter. Moreover, motor vehicle environments are extremely varied and these environmental and operational conditions influence filter performance.

Overview of Nanofibers Applications for Air Cleaning
The Need for Air Cleaning Air filtration intake systems perform a number of functions including reducing intake noise and removing moisture. Clean air is needed to prevent wear of moving parts and prevent workers in high dust environments from developing respiratory problems. All of air contaminants entering equipment can and will lead to unnecessary wear, shorter machine life, and increased maintenance costs.

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.

Sound enclosures provide weather protection and sound attenuation
With the growth of standby, prime and peaking power installations in highly populated areas, design engineers have focused their attention on understanding how generator set noise is propagated and controlled. The high cost of retrofitting a site for noise reduction makes it imperative to assess noise performance requirements early in the on-site power system design stage. This Cummins white paper outlines procedures to help, power system designers and end users more easily control unwanted noise from their on-site power system. there are basically seven strategies for reducing generator set noise: 1) reduce the sound level of the source; 2) acoustic barriers; 3) acoustic insulation; 4) isolation mounts; 5) cooling air attenuation; 6) exhaust silencers; and 7) efforts to maximize the distance between the generator set and the property line (or people). When locating generator sets outdoors, the use of enclosures – particularly sound-attenuating enclosures – combines all of these strategies into a convenient package that provides weather protection as well as sound attenuation.

Cummins Sound attenuation enclosures
Cummins Power Generation diesel and spark-ignited generator sets are available with sound-attenuated and weather-protective enclosures. Pre-assembled, pre-integrated and delivered as part of the entire power system, these enclosures are designed to speed installation time and reduce costs. Three levels of sound-attenuation, depending on model size, are available to comply with even the strictest noise requirements. Enclosures are constructed of steel or aluminum, which is preferred in coastal regions or other environments where corrosion is a concern. Three levels of sound attenuation are: Level I: 70 to 89 d(B)A* Level II: 63 to 78 d(B)A* Level III: 68 to 70 d(B)A*

Cummins CHP installations for greenhouses have short payback time
CHP for heat and CO2 production for greenhouse applications can pay back in a remarkably short time, ranging anywhere from 1.5 to 3 years in favorable conditions says Stefan De Witt of Cummins Engine. Gas-fueled generator sets are highly suitable for this application because of their excellent environmental characteristics and their efficient production of heat and electricity. When implementing a solution, the designer must consider a number of points. For the dimensioning of the CO2 equipment such as tubes and fans, for example, it is important to keep in mind the excess air factor, defined as the amount of air admitted divided by the minimum amount of air required for the complete combustion of a fuel. The amount of air for complete combustion of a fuel depends on the composition of the fuel. Combustion of approximately 35 cubic ft of natural gas at normal temperature and pressure (1 N m³) needs approximately 8.5 N m³ of air. Lean-burn engines operate at a high excess air factor (above 1.5) to keep NOx production to a minimum. Consequently, a CHP unit produces a larger volume of exhaust gases than a burner.
