摘要： An engine assembly comprises an exhaust gas recirculation circuit, an aftertreatment apparatus and a controller. The controller is configured to determine a desired proportion of exhaust gas to be directed to the exhaust gas recirculation circuit. The controller is further configured to determine, based on the proportion of exhaust gas to be directed to the exhaust gas recirculation circuit, a baseline value for an extent to which to open the exhaust gas recirculation valve for a clean aftertreatment apparatus. The controller is further configured to determine a compensation function based on an inferred aftertreatment flow restriction value. The controller is further configured to control the extent to which the exhaust gas recirculation valve is open based on the baseline value modified by the compensation function in order to maintain the desired proportion of exhaust gas to be directed to the exhaust gas recirculation circuit.

摘要： A pre-cleaner may include a plurality of spin tubes arranged side-by-side to form a row. Each spin tube may include a longitudinal axis, an inlet at a first end, and an outlet at a second end. The pre-cleaner may also include a manifold enveloping the outlets of the plurality of spin tubes and configured to receive and direct dust away from the outlets. The manifold may include a cover portion extending along and adjacent the row of spin tubes at a position along the longitudinal axis that is between the respective outlets and first ends of the spin tubes. The manifold may also include a trough extending along the row of spin tubes and defining a collection area that is arranged at a position along the longitudinal axis that is beyond the second ends of the spin tubes. A method of dust removal is also described.

摘要： A fuel filter is provided which comprises a manifold, a connector element, a filter bowl, a filter element, an inlet shutoff valve, an outlet shutoff valve, an inlet port, an inlet passage, an outlet port, an outlet passage and a relief valve in which the connector element is fixed to the manifold, and the filter bowl is reversibly fixed to the connector element. The filter bowl is adapted to reversibly receive the filter element and is so configured that when the filter element is located within the filter bowl and the filter bowl attached to the connection element the filter element divides the space defined by the connector element and filter bowl into an inlet filter chamber and an outlet filter chamber. The inlet port mouths through a surface of the manifold, and the inlet port and inlet filter chamber are in fluid communication via the inlet passage.

摘要： An improved apparatus for injecting and igniting fuel in an internal combustion engine includes a nozzle with a bore and a tip at a distal end. The bore includes a longitudinal axis and an annular valve seat. A needle reciprocates within the bore and in combination with the annular valve seat forms an injection valve where in a closed position the needle abuts the annular valve seat and in an open position the needle is spaced apart from the annular valve seat. A retainer axially protrudes from the tip of the nozzle along the longitudinal axis thereof whereby an annular mixing space extends between the retainer and the tip of the nozzle. There is an igniter secured to the nozzle that includes a positive-ignition source forming an ignition zone within a portion of the annular mixing space. Nozzle arrangements include those with both pilot hole and main holes in the nozzle extending between the plenum and outside the nozzle where the main hole longitudinal axis bypasses the retainer and a pilot fuel jet from the pilot hole(s) is retained and redirected such that an ignitable fuel-air mixture is formed within the annular mixing space. Nozzle arrangements also include nozzles with a plurality of main holes and no separate pilot holes in which the main longitudinal axis bypasses the retainer such that a main fuel jet is scraped by the retainer and scraped fuel is retained and redirected such that an ignitable fuel-air mixture is formed within the annular mixing space. The igniter is actuated to ignite the ignitable fuel-air mixtures.

摘要： A gaseous fuel-air mixer includes an outer shell, an inner shell, and a fuel chamber rib. The outer shell includes an air intake and a fuel intake. The air intake is configured to receive air. The air intake has an air outlet. The fuel intake has a fuel inlet that is configured to receive fuel. The inner shell includes an inner shell intake that is configured to separately receive the air from the air outlet and the fuel from the fuel intake and to provide a gaseous fuel-air mixture. The inner shell cooperates with the outer shell to define a fuel intake collecting chamber that is configured to receive the fuel from the fuel inlet and a fuel intake concentrating chamber that is configured to receive the fuel from the fuel intake collecting chamber and provide the fuel to the inner shell intake.

摘要： The instant invention includes systems for and methods of maximizing efficiencies in an internal combustion engine while minimizing costs and weight for the same and while also minimizing maintenance requirements for the same. Such systems include a compression assembly for compressing fluid to a desired pressure for combustion (such as above 220 psi) and a combustion assembly configured to receive at least a portion of the compressed volume of air for each power stroke. In this way, the power stroke of the engine is independent of the compression stroke of the engine, thereby eliminating or otherwise minimizing transitional losses associated with the same.
