Systems and methods for combustion engines with interchangeable components are described herein. An engine sub-assembly for a gasoline powered engine can include a crankcase having an opening extending at least through an upper surface thereof, the opening being configured to receive a crank arm therethrough, and a first mounting plate configured to be coupled with the crankcase. The first mounting plate can be selectively removable from the crankcase. The opening of the first mounting plate can generally align with the opening in the crankcase when the first mounting plate is coupled with the crankcase. The first mounting plate can be configured to receive a first cylinder block and to couple the first cylinder block to the crankcase. A second mounting plate can be configured to couple with a second cylinder block that is different than the first cylinder block and to couple the second cylinder block to the crankcase.

Methods and systems are provided for a hybrid electric vehicle including a front-wheel drive system and a rear-wheel drive system. In one example, the rear-wheel drive system includes an internal combustion engine configured to drive rear wheels of the vehicle, and the front-wheel drive system includes a first electric motor and a second electric motor mounted directly to opposing sides of the engine. The first electric motor is coupled to a first reduction gearbox to drive a first front wheel of the vehicle, and the second electric motor is coupled to a second reduction gearbox to drive a second front wheel of the vehicle.

The compression system comprises a main fluid inlet adapted to receive a production stream of natural gas; first and second stage scrubbers; first and second compression units; first and second heat exchange units; one or more liquid dump containers; and an engine. The engine operates within a range of 1600-2100 revolutions per minute and the compressed gas comprises a pressure within a range of 360-600 pounds per square inch. The system comprises a weight to thousand cubic feet of gas per day ratio of less than twenty.

A bracket kit for mounting an engine mount to three different engine blocks. The bracket kit comprises a bracket comprising an upper mounting surface and a hole having a centerline for mounting the engine mount that defines a longitudinal axis. The bracket comprises inner and outer rear mounting surfaces. The bracket comprises first and second holes extending to the inner rear mounting surface. The bracket comprises third and fourth holes extending to the outer rear mounting surface. The inner rear mounting surface is set back from the outer rear mounting surface. The bracket kit comprises a bushing removably engaged with a recessed portion of the first hole for attaching the bracket to the first engine block. The bushing may be removably engaged with a recessed portion of the second hole for attaching the bracket to the second engine block or the third engine block.

An engine assembly having an improved mounting system or assembly is disclosed. Features of this mounting system include having crankcase arms that are integrally formed with a crankcase of the engine assembly, having multiple mounting legs that each have a dedicated vibration damping subassembly and where the stiffness of at least two of the mounting legs is different (by varying the configurations of the corresponding vibration damping subassemblies), and using a mounting ring or base with having differently oriented mounting pads for securement of the corresponding mounting leg relative thereto.

A cylinder head pallet includes: a base plate; a subplate disposed upwardly of the base plate, spaced apart from the base plate, and having a first surface and a second surface that oppose each other; and a plurality of posts installed on the first surface and the second surface of the subplate to support a cylinder head.

An engine device including a cylinder block (6) for supporting a crankshaft so that the crankshaft is rotatable. Opposite side portions (301, 302) of the cylinder block (6) along a crankshaft axial direction have, on one of their ends relative to the crankshaft axial direction, projecting portions (304, 305) protruding in a direction away from the crankshaft, and reinforcing ribs (306, 307, 308, 309, 310, 311) provided between side walls and the projecting portions (304, 305) of the opposite side portions (301, 302) so that the reinforcing ribs (306, 307, 308, 309, 310, 311) are widened at their sides close to the corresponding projecting portions (304, 305), the projecting portions (304, 305) and the reinforcing ribs (306, 307, 308, 309, 310, 311) being integrally formed with the cylinder block (6).

Methods and systems are provided for a hybrid electric vehicle including a front-wheel drive system and a rear-wheel drive system. In one example, the rear-wheel drive system includes an internal combustion engine configured to drive rear wheels of the vehicle, and the front-wheel drive system includes a first electric motor and a second electric motor mounted directly to opposing sides of the engine. The first electric motor is coupled to a first reduction gearbox to drive a first front wheel of the vehicle, and the second electric motor is coupled to a second reduction gearbox to drive a second front wheel of the vehicle.

An internal combustion engine for a motorcycle includes a rear cylinder head, the rear cylinder head being provided with a camshaft, an exhaust rocker arm rocked by the camshaft, an engine valve closed/opened by being push-pressed by the exhaust rocker arm, and a rocker arm shaft swingably supporting the exhaust rocker arm. In the internal combustion engine for the motorcycle, the rear cylinder head is provided separately from a holder member, the holder member being provided adjacently to the rear cylinder head, the camshaft is rotatably supported by the holder member, and the holder member is provided with right and left rear side walls and internal combustion engine supporting portions, the right and left rear side walls supporting the rocker arm shaft, the internal combustion engine supporting portion being supported by a vehicle body frame.

A flow guiding appliance of a turbomachine, in particular of an aircraft engine, for a partial exit flow of an outlet guide vane of a compressor, wherein, a flow guiding element delimits an annular channel about a shaft of the turbomachine. A frictional engagement connecting surface at the circumference of the flow guiding element connects the flow guiding element to another structural component of the turbomachine. The frictional engagement connecting surface with a closed enveloping surface can be inserted in a deformed state into the structural component with a circular cylindrical sealing surface with at least two opposite points. The at least two points of the closed enveloping surface are arranged in at least two opposite frictionally engaged contact areas of the circular cylindrical sealing surface following deformation. The invention also relates to a method for creating a flow guiding element.
