Abstract: An internal combustion engine has a first and a second cylinder bank. The first and second cylinder banks are arranged such that they have less than a 180 degree included angle with respect to one another, thereby forming an inboard region or generally V-shaped cavity. A respective first and second cylinder head is mounted with respect to the first and second cylinder bank. Integrated within the first and second cylinder head is a first and second integrated exhaust manifold, respectively. The first and second integrated exhaust manifolds are provided on the engine in an “inboard” orientation, i.e. disposed on a side of their respective cylinder heads such that they are substantially adjacent to the generally V-shaped cavity. The first and second integrated exhaust manifold may operate to convey exhaust gases from the engine to at least one turbocharger, which is mounted substantially within the generally V-shaped cavity.

Abstract: An exhaust gas recirculation cooler may include a housing and a first wall. The housing may include an exhaust gas region, a coolant region, an exhaust gas inlet, and an exhaust gas outlet. The first wall may be fixed within the housing and may separate the exhaust gas region from the coolant region. The first wall may include a first portion formed from a first material and facing the exhaust gas region and a second portion formed from a second material and facing the coolant region. One of the first and second materials may have a coefficient of thermal expansion that is greater than the other of the first and second materials. The first wall may be deflected toward one of the exhaust gas region and the coolant region during cooler operation based on a difference in the coefficient of thermal expansion of the first and second materials.

Abstract: An automatic docking system for docking a towing vehicle with a towed vehicle includes a sensing device, a controller, an automatic steering system, an automatic braking system, and a plurality of targets. The sensing device detects the plurality of targets located on a hitch of the towed vehicle. The controller determines the location of the towing vehicle relative to the towed vehicle based on the detection of the plurality of targets. The controller automatically steers the towing vehicle towards the towed vehicle to assist in the docking of the towing vehicle to the towed vehicle. The controller engages the automatic braking system to slow or stop the towing vehicle as required.

Abstract: A method may include operating an engine in a first valvetrain mode during a first engine operating condition, operating the engine in a second valvetrain mode different from the first valvetrain mode during a second engine operating condition, and controlling a temperature of an exhaust aftertreatment component in communication with an exhaust gas from the engine during the second engine operating condition based on the second valvetrain mode.

Abstract: An exhaust gas cooling apparatus and method for cooling an exhaust gas is provided. The exhaust cooling apparatus has a first fluid conduit and a variable nozzle extending from the first fluid conduit. The variable nozzle being disposed in an inlet end of a second fluid conduit, wherein the variable nozzle has at least two dissimilar materials adjacent to each other and a fluid inlet opening is located between an outer periphery of the variable nozzle and an inner surface of the inlet end of the second fluid conduit. The at least two dissimilar materials vary the size of an opening of the variable nozzle by moving toward or away from a center line of the first fluid conduit in response to a temperature of an exhaust gas flowing through the first fluid conduit.

Abstract: An engine including an exhaust system operable to convey exhaust gases from the engine. A turbocharger is in fluid communication with the exhaust system. A diesel particulate filter, disposed in fluid communication with the exhaust system and located in downstream relation to the turbocharger, operates to substantially remove particulate matter from within the exhaust gases. An exhaust gas recirculation passage, disposed in downstream relation from the diesel particulate filter, operates to communicate a portion of the exhaust gases to an air-to-air heat exchanger, which operates to cool the portion of the exhaust gases. An exhaust gas recirculation valve operates to selectively and variably communicate the portion of the exhaust gases to an inlet air duct of an intake system. An engine cover defines an opening operable to communicate ambient air to the air-to-air heat exchanger to promote the cooling of the portion of the exhaust gases.

Abstract: A turbocharged V type engine can be equipped with an exhaust gas recirculation cooler integrated into the intake manifold, so as to achieve efficiency, cost reductions and space economization improvements. The cooler can take the form of a tube-shell heat exchanger that utilizes a cylindrical chamber in the air intake manifold as the heat exchanger housing. The intake manifold depends into the central space formed by the two banks of cylinders on the V type engine, such that the central space is effectively utilized for containing the manifold and cooler.

Abstract: A method and apparatus for detecting the degree of deterioration of a lubricating oil for an operating machine includes a grid-like capacitive sensor that uses the lubricating oil as a dielectric medium. A magnetic field is imposed upon the oil to attract ferromagnetic wear particles into the vicinity of the sensor. Preferably, the magnetic field is generated by at least two independently controlled electromagnet windings aligned such that the magnetic field produced by each winding acts upon the wear particles. A plurality of capacitance measurements are taken at periodic intervals at each of several magnet operational states for respective classification and analysis. All windings may be simultaneously de-energized for release of captured particles back in to an oil circulation stream and to clean the capacitative sensor grid of accumulated particulates.
