Bypass Centrifuge Extends Engine Life

Bypass Centrifuge Extends Engine Life ENGINES Engines When FARM SHOW first wrote about Dieselcraft bypass centrifuges 4 years ago Vol 31 No 3 they were in high demand for processing vegetable oil and waste oil for burning in diesel engines But they re also the best way out there to keep engine oil clean Centrifuges remove moisture and particles from engine oil Early units were gravity-fed and had to be mounted above the engine a problem in today s tightly packed engine compartments We needed a massive drain hole back into the engine recalls John Nightingale Dieselcraft Fluid Engineering What we needed was air pressure to push the oil back into the engine Nightingale attached a small compressor to the centrifuge This allows the unit to be mounted anyplace under the hood Air pressure can push the oil up to 3 ft vertically or up to 7 ft horizontally You can mount it down on the frame rail if necessary says Nightingale All you need is a 6 by 6 by 6-in space Other factors that are building interest in the centrifuge include the increasing cost of oil changes and the difficulty of filtering new longer lasting synthetic oils Changing oil in a big front-end loader may have to be done every 250 hrs at a cost of $1 500 says Nightingale We ran tests on one and demonstrated that by switching to synthetic oil and our centrifuge the loader could go at least 750 hrs without changing oil or filters Though synthetic oil lasts longer as an effective lubricant it also prevents the natural clumping of dirt and other particles by molecular attraction necessary for optimal filtering While carbon particles of 0 1 microns or less may not affect lubrication they can build up on cylinder walls and other places and affect additive anti-wear effectiveness Without centrifugal action it s hard to clean carbon and other particles out of synthetic oil The best filters only extract down to 7 microns and regular oil filters only catch particles 25 microns and larger Those small particles can only be removed by a centrifuge says Nightingale Our centrifuges remove particles as small as 1/10 of one micron Dieselcraft offers a unit the OC-25 for cars pickups and smaller engines It s priced at $599 A larger unit the Magnum Model 180 AP is recommended for engines with 100-gal sumps and larger It is priced at $699 Contact: FARM SHOW Followup John T Nightingale Magnum Group Dieselcraft Fluid Engineering P O Box 7670 Auburn Calif 95604 ph 530 613-2150; sales@dieselcraft com; www dieselcraft com
