摘要： An exhaust emission reduction system for a fuel injected engine system has a plurality of emission reduction components configured to process the exhaust gas. The emissions reduction components include of one or more NOx reduction components and one or more filtration components configured to reduce particulate matter, hydrocarbons and/or carbon monoxide emissions. Each engine cylinder is associated with a respective one of the emission reduction components, such that exhaust gas from each engine cylinder flows through the respective one emission reduction component in parallel with the exhaust gas flows from the other cylinders through their respective emission reduction components.

摘要： The present invention generally relates to a new valve guide for use in an exhaust valve system. Specifically, the invention is related to a valve guide that prevents acidic corrosion between the valve and the valve guide. The valve guide includes a number of contact portions, which engage the channel that is formed in the cylinder head near the exhaust port. The valve guide also includes a recess portion, situated in relation to a water jacket and between the contact portions. The recess portion and contact portions are sized and shaped to maintain the surface temperature of the valve guide to prevent condensation of acidic gases between the valve stem and the valve guide.

摘要： 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.

摘要： A charge air cooler is composed of a framed heat exchange core which is sealably attached in a selectively removable manner with any suitably shaped inlet and outlet ducts, and is, at the other sides thereof provided with cover panels which collectively necessitate that all of the hot charge air coming from the turbocharger pass entirely through the heat exchange core. In this regard, the heat exchange core is provided with a pair of opposingly disposed mounting frames, each of which being connected sealably to a commensurately sized and configured mounting flange of an inlet duct or an outlet duct.

摘要： An accurate method of determining the power developed by selected cylinders of a multiple cylinder engine is based on the concept of controlling engine rpm for test purposes by adjusting the load on the engine instead of controlling speed by adjusting the fuel rate as is commonly done in normal engine operation. The method may be utilized for evaluating cylinder performance and for accurately balancing the output of the individual cylinders. It is particularly useful in railroad applications where the engine operates a generator that produces electric power and the system is provided with dynamic braking grids, which can be utilized as resistor grids for load testing the engine. However, the method is also applicable to other engines and other engine arrangements where engine power may be absorbed by a generator or dynamometer for controlling the load for test purposes.

摘要： A coupling mechanism for a sealing structure having interacting seals in non-parallel planes includes a male portion of a mechanical joint and a female portion of the mechanical joint. The male portion is coupled with a first sealing member contained in a first plane. The female portion is coupled with a second sealing member which is contained in a second plane. The second plane is different from the first plane. The male portion and the female portion of the mechanical joint are configured to mate for coupling the first sealing member with the second sealing member.

摘要： A valve assembly of a fuel supply system includes a first body defining a first bore, an inlet port to receive fuel into the first bore, and an outlet port. The valve assembly further includes a pneumatic chamber disposed in fluid communication with the first bore. The valve assembly further includes a first piston to move between a first position and a second position. The first piston restricts and allows flow of fuel from the inlet port to the outlet port, in the first position and the second position, respectively. The valve assembly further includes a vent passage located upstream of the pneumatic chamber and configured to receive fuel leaked from a flow path defined between the inlet port and the outlet port. The valve assembly also includes a check valve disposed in the vent passage and configured to selectively vent the fuel entering the vent passage.
