A system and method for managing the characteristics of engine oil in a lubrication system for an internal combustion engine is disclosed. Generally speaking, the method includes the steps of determining a target viscosity for the engine oil based on engine speed and engine load, determining a working viscosity which may be directly measured or determined based on engine oil temperature and engine oil type, comparing the target viscosity to the working viscosity, deriving a target engine oil temperature, and directing engine oil to one of an oil cooler, an oil heater, or neither when and until the target engine oil temperature is achieved. The oil viscosity management system includes an engine lubrication system having a volume of engine oil, a cooler coupled to the lubrication system, a heating mechanism also coupled to the lubrication system, a valving system for directing flow of the oil and coupled to each of the lubrication system, the cooler and the heating mechanism, a signal generator for generating a signal based on operational parameters of the engine, and an estimator for controlling the valving system in response to the signal.

A mount () for mounting an exhaust gas component () in an exhaust pipe () or in a component housing includes a spring band () and a plurality of spring fingers (). The spring band () is configured to contact and substantially pass around an outer surface () of the exhaust gas component (). The plurality of spring fingers () extend from the spring band () generally axially with respect to the exhaust gas component () and generally radially from the spring band. The spring fingers () contact the exhaust gas component ().

A mixer assembly () for mixing intake air from an intake system () with exhaust gas from an exhaust gas recirculation system () to yield a mixture stream includes an intake air conduit () having an inlet () fluidly connected to the intake system. The mixer assembly () also includes a mixer () having an inlet () fluidly connected to the exhaust gas recirculation system (). The mixer () is at least partially disposed in the intake air conduit () and includes an outer pipe () and a dividing portion () disposed within the outer pipe. The dividing portion () divides a first passage () from at least one second passage (), the first passage having an outlet (') that is at a first height, and the second passage having an outlet (&#x2032;) that is at a second height.

A cylinder head of an engine is disclosed, the cylinder head including an upper deck, a lower deck, and a sidewall extending between the upper deck and the lower deck. The lower deck defines a block-engaging portion and a combustion chamber flame deck. The combustion chamber flame deck is spaced apart from the block-engaging portion. An engine is also disclosed that includes a cylinder block having a cylinder bore, and a piston slidably positioned within the cylinder bore. The engine also includes a cylinder head having a lower deck connected to the cylinder block, the lower deck defining a block-engaging portion and a combustion chamber flame deck. The combustion chamber flame deck is spaced apart from the block-engaging portion by a recess.

A lightweight knuckle weighing substantially less than an AAR Standard Knuckle, is described for use in a railroad car coupler. This lightweight knuckle can be used, for example, to replace AAR Standard knuckle which becomes broken or otherwise damaged during operation and requires replacement in the field. Both the contouring and inner coring of an AAR Standard knuckle are radically changed to produce this lightweight knuckle which has all the functioning features of the standard knuckle, so as not to adversely effect the coupling and uncoupling operations of a coupler in which the lightweight knuckle is used.

Lightweight knuckle for a railroad car coupler

An improved lightweight knuckle is described for use in an AAR Standard E or F type railroad car coupler. The outer contouring and inner voids of the improved lightweight knuckle are radically changed without compromising the integrity or operability of the knuckle during conventional coupling and uncoupling operations with, and from, an existing AAR Standard knuckle. The nose of the improved lightweight knuckle is provided with a pair of parallel, coplanar flat surfaces between which is a projection which extend outwardly from the flat surfaces and terminates at an outer curved surface which has the same curvature as the corresponding curvature of an existing AAR Standard knuckle. Also, twin sets of reinforcement ribs are provided within the improved lightweight knuckle to strengthen the knuckle and make it more durable.
