Abstract: Methods and systems are provided for operating a split exhaust engine system that provides blowthrough air and exhaust gas recirculation to an intake passage via a first exhaust manifold and exhaust gas to an exhaust passage via a second exhaust manifold. In one example, in response to an intake throttle being at least partially closed, intake air may be routed from the intake passage to the first exhaust manifold via an exhaust gas recirculation (EGR) passage where the intake air may be heated via an EGR cooler. The heated intake air may then be routed to an intake manifold, downstream of the intake throttle, via a flow passage coupled between the first exhaust manifold and the intake manifold.

Abstract: The present invention is to prevent mixing of fresh air and an air-fuel mixture when a throttle valve is fully opened and increase a delivery ratio. A main nozzle (30) is surrounded by a tunnel-like air flow guiding member (52). The air flow guiding member (52) is opened at its front and back sides. A whole amount of fuel discharged via a main nozzle (30) is sent to a downstream side by an air flow created by the air flow guiding member (52). When a throttle valve (22) and a choke valve (24) are both in a fully-opened state, fresh air flows into an air-fuel mixture passage (12) through a gap between these valves (22, 24).

Abstract: A GDCI engine control system provides rapid heating of intake air to the combustion chamber when the engine is cold. The engine uses an intake air pathway that includes a compressor having a compressor inlet and a compressor outlet. A loop fluidly connects the compressor outlet to the compressor inlet. First and second valves are arranged in the loop and are arranged near the compressor outlet and the compressor inlet respectively. First and second passages converge at a first junction, and the first passage fluidly connects the first valve and the first junction. The second passage fluidly connects to the loop at a second junction arranged fluidly between the first and second valves. An intake air heat exchanger is arranged in the first passage and fluidly between the first valve and the first junction.

Abstract: A sprung gate for a valve having an endless elastic band sandwiched between first and second gate members that each define an opening therethrough in an open position portion thereof, which collectively form a passage through the sprung gate. The first gate member includes a fastener connected to a fastener receiving member of the second gate member thereby securing the first and second gate members together as a unit. This sprung gate unit is operatively connected to an actuator for linear translation within a pocket of a conduit to control fluid flow through the conduit. This assembled device may be manufactured using spin welding to sealingly mate the conduit to a housing enclosing the actuator.

Abstract: The engine shut-off valve system includes a housing, a gate member, a rotating lever, a locking piston assembly, and a closing piston assembly. The system is installed in fluid connection with a flow line so that air flow passes through a passageway in the housing with the gate member in the locked configuration. The air flow through the passageway stops with the gate member in the closed configuration. The gate member has an asymmetry so that the forces of the spring of the closing piston assembly and the spring of the locking piston assembly are cooperative to actuate between the closed configuration and the locked configuration, while wearing on the gate member differently so as to extend the working life of the valve system. The closing piston assembly and the locking piston assembly are separately accessible for maintenance.

Abstract: A throttle drive actuator for an engine includes a first magnet and a second magnet positioned adjacent the first magnet. The north pole of the second magnet is positioned opposite the south pole of the first magnet to create a first magnetic field, and the south pole of the second magnet is positioned opposite the north pole of the first magnet to create a second magnetic field. A direction of the second magnetic field is directed opposite a direction of the first magnetic field. An armature is positioned between the first magnet and the second magnet, the armature including windings. The armature rotates between the first magnet and the second magnet when the windings are energized, and the armature rotates a valve of a throttle body of the engine, to open a close an air passage of the throttle body.
