And the intake manifold M connects an upper half part Mu, comprising the first and the second blocks B1, B2, with a bottom half part Ml, consisting of the valve holding plate 24 and the third block B3, by a junction surface F1 while the upper half part Mu to each cylinder head 3 by a mounting surface F2, arranging the surfaces F1 and F2 in a signal plane.
Abstract:
An internal combustion engine for a vehicle, such as a motorcycle, includes a crankcase, two banks of cylinders projecting from the crankcase in a 56-57 degree V-configuration, a plurality of pushrods, and a plurality of camshafts supported by the crankcase. The two banks of cylinders include a first cylinder bank that projects from the crankcase to a first cylinder head, and a second cylinder bank that projects from the crankcase to a second cylinder head. The plurality of intake and exhaust valve pushrods extend between the crankcase and the first and second cylinder heads, driven by one intake camshaft and two exhaust camshafts.
Abstract:
An internal combustion engine (300) for a vehicle, such as a motorcycle (20), includes a crankcase (380), two banks of cylinders (320a, 320b) projecting from the crankcase (380) in a V-configuration, a plurality of pushrods (364), and a plurality of camshafts (360a, 360b, 360c) supported by the crankcase (380). The two banks of cylinders (320a, 320b) include a first cylinder bank that projects from the crankcase (380) to a first cylinder head (340a), and a second cylinder bank that projects from the crankcase (380) to a second cylinder head (340b). The plurality of pushrods extend between the crankcase (380) and the first and second cylinder heads (340a, 340b), and the plurality of camshafts include only the first, second and third camshafts (360a, 360b, 360c).
Abstract:
There is provided a supercharger system for supercharging a vehicle engine includes a first lower intake manifold adapter attached to the vehicle engine. The supercharger system further includes a second lower intake manifold adapter attached to the vehicle engine. The first and second lower intake manifold adapters can be attached to respective first and second cylinder heads of the vehicle engine. The supercharger system further includes a plate situated between the first and the second lower intake manifold adapter, where the plate is adapted to receive a supercharger on a bottom surface of the plate. The supercharger provides compressed air that flows through the first and the second lower intake manifold adapter to the vehicle engine. The supercharger system further includes an upper manifold plenum chamber situated over the plate, where the upper manifold plenum chamber receives the compressed air from the supercharger.
Abstract:
An intake manifold mixes and supplies air and exhaust recirculation gas (EGR) to an internal combustion engine. The manifold is a casting and includes an air intake port, an intake chamber receiving intake air from the intake port, an outlet plenum communicated with the engine, an EGR inlet port, and first and second EGR valve chambers. A first EGR passage communicates the EGR inlet port with the first EGR valve chamber. A second EGR passage communicates the EGR inlet port with the second EGR valve chamber. A central EGR outlet passage communicates an end of each EGR valve chamber with a central portion of the plenum. First and second EGR outlet chambers receive EGR from the first and second valve chambers, and have outlet ports which communicate with first and second ends of the plenum. A wall separates the intake chamber from the central EGR outlet passage chamber and from one of the EGR inlet passages. The wall creating turbulence as the EGR from the central EGR outlet passage mixes with intake air from the intake chamber.
Abstract:
The present invention relates to a modified intake manifold having short runner valves in the manifold tuning valve. Anti-chatter devices are disclosed for reducing shaft chatter without placing friction on the shafts. A lost motion linkage is used to ensure closure of the short runner valves. Radiused seating surfaces are used for seating of the manifold tuning valve.
Abstract:
In an induction system for an internal combustion engine having two groups of cylinders of which firing orders are respectively discontinuous, a groove is formed in a joining end face of a collector unit to be joined with a joining end face of an intake manifold in such a manner as to have a straight main groove section disposed between first and second groups of outlet ports so as to be equidistant from the outlet ports and a plurality of outlet groove sections branching off from the main groove section to fluidly connect the main groove section to each outlet ports. When the joining end faces of the collector unit and the intake manifold are joined together, a fluid recirculation passage such as a blow-by gas recirculation passage, an exhaust gas recirculation passage or the like is defined therebetween.

Abstract:
A fuel injector adapter for providing nitrous oxide to an internal combustion engine is disclosed. The nozzle has a central fuel injector passage that terminates at a first outlet end. Fuel from a fuel injector may be passed through the central fuel injector passage. The nozzle also has an inner annular passage. The inner annular passage terminates at a second outlet end. The nozzle also has an outer annular passage arranged circumferentially around the inner annular passage that terminates at a third outlet end. One or both of the inner and outer annular passages is adapted to pass nitrous oxide through it. The nozzle is adapted to fit between a fuel injector and an engine without substantial modification to the engine.
