    Abstract: A switchable rocker arm for valve deactivation is provided for a valve train of an internal combustion engine. The switchable rocker arm includes a cam lever assembly, a valve lever assembly, and a hydraulically actuated coupling assembly that is radially arranged between the cam lever and valve lever assemblies. The coupling assembly includes a shuttle pin, a locking pin with a round or flat locking interface, and optional shuttle pin and locking pin sleeves. In a first, locked position, the rotational motion of a camshaft is translated to linear motion of an engine valve. In a second, unlocked position, the cam lever assembly rotates about the valve lever assembly, facilitating valve deactivation. A pivot joint arranged between the cam lever and valve lever assemblies facilitates an arcuate lost motion of the cam lever assembly. An integrated arrangement for one or more lost motions springs offers packaging and functional advantages.

  • Publication number: 20170009621
    Abstract: An engine control device sets a target value for the engine oil temperature appropriately in an engine that uses gasoline as a fuel, even when the fuel does not have a single boiling point because the gasoline is a mixed composition, or when the fuel property changes (for example, when the vaporization property changes due to deterioration). In other words, the engine control device prevents excessive heating or insufficient heating by changing the oil temperature to the high side in a condition wherein the fuel being used does not easily vaporize, and changing the oil temperature to the low side in a condition wherein the fuel being used easily vaporizes. This engine control device includes an oil temperature controller that controls the temperature of oil lubricating the interior of the engine; a fuel supply device that supplies fuel to the engine; and a detector for detecting the property of the fuel. The temperature of the oil is controlled on the basis of a signal from the detector.

  • Publication number: 20170009647
    Abstract: A connecting rod for an engine is provided. The connecting rod includes a first connecting rod portion and a second connecting rod portion. The second connecting rod portion is adapted to move with respect to the first connecting rod portion. The connecting rod further includes a compressible fluid contained in an internal volume. The compressible fluid is adapted to vary a length of the connecting rod such that the length of the connecting rod decreases based on a compression of the compressible fluid. Further, the length of the connecting rod increases based on an expansion of the compressible fluid. The connecting rod also includes at least one limit stop adapted to restrict a movement of the second connecting portion beyond a predefined limit. Further, the connecting rod is adapted to passively vary a compression ratio of the engine based on the variation in the length of the connecting rod.

  • Publication number: 20170009648
    Abstract: A four-stroke internal combustion engine with variable compression ratio, comprises a crankcase, a crankshaft, a connecting rod having a big end and a small end. A piston is rotatably connected to the small end. A crank member rotatably mounted on the crankpin has a bearing portion which is eccentrically disposed with respect to the crankpin, wherein the bearing portion has an outer circumferential wall including a location of maximum eccentricity (P) which bears the big end of the connecting rod such that the connecting rod is rotatably mounted on the bearing portion of the crank member via the big end. Under operating conditions at or close to top dead center of the piston the angle between the connecting rod plane and the piston plane changes from a pre-angle before top dead center to a post-angle after top dead center.

    Abstract: A moment-cancelling, four-stroke engine is disclosed. The engine includes a first cylinder having a first piston and a second cylinder having a second piston, a first crankshaft operably connected to the first piston and a second crankshaft operably connected to the second piston. The first crankshaft rotates in a first direction and the second crankshaft rotates in a second direction that is opposite the first direction to cancel the moments applied to the engine and reduce engine vibration.

  • Publication number: 20170009650
    Abstract: According to the present invention, there is provided a secondary engine cover formed from a polymeric material comprising a wear indicator. It is recommended and encouraged that teams, and track day public, replace the secondary engine cover after each and every crash, to ensure the best rider safety possible. However, because of some products inherent high performance and durability, this good practice has not always been followed. Some deem that it is not always necessary to change, a practice that it is not wished to encourage and which should be changed. In this invention, wear indicators are created in one alternative in the form of round holes appearing in on the top surface of the secondary engine cover when crucial areas of material of the secondary engine cover have been worn down.

  • Publication number: 20170009651
    Abstract: The present invention generally relates to a sequential combustor for a gas turbine having second and/or subsequent stages of a re-heat, sequential or axially-staged combustion system. A variation in Mach number along the flow path can be used to control static temperature variation, which in turn influences the progress of auto-ignition reactions that eventually lead to the onset of combustion.

  • Publication number: 20170009652
    Abstract: Systems and methods are provided for combined cycle power generation while reducing or mitigating emissions during power generation. Recycled exhaust gas from a power generation combustion reaction can be separated using a swing adsorption process so as to generate a high purity CO2 stream while reducing/minimizing the energy required for the separation and without having to reduce the temperature of the exhaust gas. This can allow for improved energy recovery while also generating high purity streams of carbon dioxide and nitrogen.
