Abstract:
Intake and exhaust manifolds (300, 300c) include a plurality of interconnected furcation members (312, 304a, 304b) wherein each furcation member defines a primary passage (318) that branches into secondary passages (310, 314). The furcation members are arranged in levels such that the number of passages within a manifold decrease in levels more fluidly distant from the machine associated therewith. Each first level furcation member (304) defines two secondary passages (306, 308) that are individually in fluid communication with working chambers of a machine that includes a plurality of sequentially pulsing work chambers (c1-c4). Each secondary passage (306, 308) of a first level furcation member individually extends toward and fluidly communicates with a working chamber that pulses half way through the operating order from the working chamber that the other secondary passage of that first level furcation member extends toward and fluidly communicates with. Throughout the manifolds, the secondary passages (306, 308) of a representative furcation member each have an identical, yet out of phase, pulse interval.
Abstract:
The objective is to provide a resin air intake system provided with an intake control valve which permits simplifying the mold structure and maintaining axis center precision. In an air intake manifold with air intake passages (13) and (14) are fabricated to be opened and provided with an intake control valve (31) supported by a shaft (30) having an axis in the direction perpendicular to the axes of the openings (16), the air intake manifold is molded from a resin comprising at least an air intake manifold proper (10) and an air intake manifold cluster (20) which have split faces for the two, the split face of the air intake manifold proper (10) is provided with groove (18) in a direction perpendicular to the axes of the openings (16), bearings (32) which slidably support shaft (30) are mounted to be in the grooves (19), and a projection which projects from the split face of the air intake manifold cluster is brought into contact with the bearings (32).
Abstract:
An intake system for a reciprocating internal combustion engine adapted to control operation of the engine to produce a high level of torque across a wide range of engine revolutions. The intake system is formed by a plenum (3) feeding a plurality of manifold tubes (4) dimensioned so as to improve volumetric efficiency of the engine by inducing ram air effects in a naturally aspirated engine over a wide range of rotational speeds. There is also disclosed an exhaust system which makes use of kinetic effects to improve cylinder charging and scavenging and an air flow throttle control device.
Abstract:
A thermal fuel delivery system includes an insertion assembly and a fuel device. The insertion assembly includes a housing defining a cavity for housing the fuel device. The housing is disposed above and coupled to a pair of frame members via a plurality of connecting members. The frame members extend laterally away from the housing. The insertion assembly further includes an intake manifold coupled to the housing via a tube. A plurality of runner tubes extend laterally away from the intake manifold and pass through the frame members at an inner portion of the frame members and terminate at an outer portion of the frame members.
Abstract:
An air intake manifold for an internal combustion engine having a top shell and a base weldment. The base weldment is formed by permanent joining of a bottom shell having a plurality of air outlets with a runner assembly having a plurality of runner components each having an air inlet and an air outlet, wherein the plurality of runner components are attached to one another via a support member to form the runner assembly.
Abstract:
A two-wheeled vehicle (2) includes a frame (4) and a plurality of ground-engaging members (6, 8) for supporting the frame. An engine (12) includes an air deflector (1250) to assist in cooling a rear cylinder (1172) of a V-twin engine. An accessory windshield (1650) is also shown which may be coupled to the handlebars (28) and front forks (72) of the vehicle. Also, a rear accessory attachment is shown mountable to the rear fender.
Abstract:
Systems and methods for intake manifold overpressure compensation for internal combustion engines with gaseous induction fuel systems are disclosed. The systems and methods include a connecting element that extends between and fluidly connects the downstream ends of first and second intake manifold banks of the internal combustion engine.
Abstract:
An intake control system for a multi-cylinder combustion engine with control valves positioned within intake passageways that can vary the cross- sectional area of the intake runners to increase air intake velocity at low engine speeds. The control system includes an inner frame that can be inserted into a lower manifold after manufacture. The inner frame includes a plurality of flapper valves that are actuated by a four-bar link design, which is driven by a hypoid gear-set. The control system controls an internal DC electric motor that actuates a worm-drive gear-set, which in turn drives the hypoid gear-set to either engage or retract the flapper valves within the intake passageways.
Abstract:
An engine comprises an intake manifold, first and second cylinder banks, a turbocharger, a flow passage, and first and second cylinder banks. The first and second cylinder banks are each in fluid communication with a respective output of the intake manifold. The turbocharger is associated with the second cylinder bank and includes a compressor input port and a compressor output port. The flow passage is in fluid communication with each of the compressor output port and an input of the intake manifold.
