	Fleetguard Releases Environmentally-Friendly Enviroguard Crankcase Ventilation System
	15 JUN 03 -- Fleetguard Inc. is introducing a new line of products designed to address diesel crankcase emissions. The new line, called Enviroguard™, uses patented technologies to control oil drip and filter crankcase aerosols in diesel engine applications. The new Enviroguard system requires no service, and is designed to last the life of the engine. The patented technology in all Enviroguard™ systems provides superior aerosol filtering of crankcase emissions, commonly known as blowby. Blowby is the result of high pressure gases and oils escaping around piston rings and venting to the atmosphere. The oily mist attracts dust and airborne particles, resulting in an accumulation of contaminants, both on the engine and on the surface beneath it. This condition increases the clean-up required in the engine compartment, as well as results in unsightly oil drips on highways, parking lots, garage floors and driveways. The Enviroguard™ system is six times more efficient than conventional wire mesh breather systems in filtering aerosol emissions. The system captures, separates and coalesces air particulates in the blowby emissions and returns the oil to the crankcase with filtered gases vented to the atmosphere. During 500,000 miles of operation, oil drip from a wire mesh breather system can result in as much as two quarts of oil. The Enviroguard™ system reduces oil drip to less than six tablespoons. The initial Enviroguard™ system is designed for all Cummins ISB, ISC and ISL series engine applications. Primary applications are recreational vehicles, fire trucks and buses. Future systems will be introduced to cover most diesel engine applications. Fleetguard Inc., headquartered in Nashville, Tenn., is a business unit of Cummins Inc. and the global manufacturer and specialist of filtration, exhaust and chemical and cooling products and systems for diesel engines (9-7000 horsepower).
