Abstract: A lubrication system for an engine is disclosed. The lubrication system may have an oil pump configured to lubricate the engine. The lubrication system may also have a valve configured to direct oil from the oil pump to a fuel pump associated with the engine. The lubrication system may further have a controller. The controller may be configured to determine an operating speed of the engine. The controller may also be configured to adjust the valve to selectively direct the oil to the fuel pump based on the operating speed.

Abstract: An optimized two-stroke internal combustion diesel engine, suitable for locomotive applications, has been developed to meet the EPA locomotive Tier 2 emission standards. To achieve a low emission target below the EPA Tier 2 standards for NOx (5.5 g/bhp-hr) and particulates (0.2 g/bhp-hr), several innovative changes have been made to the engine. These changes include: a new piston bowl geometry; low oil consumption piston rings; optimized surface finish cylinder liner; optimized fuel injection camlobe; modified fuel injector nozzle; new efficient aftercooler; optimized oil separator; and optimized turbocharger.

Abstract: Engine reconfiguration kits are developed for NOx emission reduction in Electro-Motive Division of General Motors Corporation model 645 diesel engines. The kits feature improved unit fuel injectors providing better fuel atomization with retarded injection timing and other improvements. Included new higher efficiency four pass counterflow aftercoolers provide reduced airbox inlet air temperatures. New connector pipes for the counterflow aftercoolers may also be included. Optional higher compression ratio pistons are available for increased fuel efficiency in some engine types. The kits reduce NOx emissions without increasing smoke, CO or particulate emissions or reducing performance.

Abstract: A diesel engine emission control system which optimizes fuel injection timing over a range of air temperatures, air pressures, and engine air flow rates. The emission control system includes a control module interfacing with a fuel injection timing module which in turn interfaces with an engine fuel injection system having fuel injectors. The control module receives data from an air temperature sensor, an air pressure sensor, and an engine boost pressure sensor. The control module determines air density and the air flow rate through the engine to determine optimal fuel injection timing. The injection timing information is relayed to the injection timing module which alters the timing of the fuel injectors to operate the engine at a maximum efficiency possible within applicable emission regulation limits.

Abstract: A process and apparatus for the production of glass fiber is disclosed. The process and apparatus are directed to collecting filaments being drawn from streams of liquid glass into a plurality of loosely bound strands of filaments which additionally are not treated with any binders. The strands are then drawn off individually on separated but parallel rotating surfaces to provide the filaments with a desired diameter.
