Rypos rolls out new diesel engine filter




Rypos Inc. recently introduced the Rypos Active Filter, which is designed to remove up to 90 percent of soot and automatically regenerate itself within the diesel engine of a locomotive, ship, oilrig or aircraft.

The filter can be used in conjunction with a diesel oxidation catalyst to reduce soluble organic materials, hydrocarbons and carbon monoxide in engine exhaust. The filter also is designed to help railroads meet the U.S. Environmental Protection Agency's new emission standards that take effect in 2007.

"Passive filters, typically made of a ceramic material, impede exhaust and sometimes diesel fuel is sprayed directly into the exhaust stream to burn off soot, which is wasteful," said Rypos founder and President Klaus Peter in a prepared statement. "To trap fine particles, Rypos developed a filter made of sintered metal — a mesh of high-heat resistant metal fibers that look like steel wool."
