摘要:
Systems and methods for modulating fuel flow of a fuel delivery system including direct injection fuel injectors of an engine to mitigate engine noise are provided. An example of such systems may include a modulating device located in the fuel delivery system upstream of the direct injection fuel injectors, the modulating device configured to generate mitigating fuel pressure pulse(s) for attenuating fuel pressure pulse(s) generated by actuation of the direct injection fuel injectors. An example of such methods may include adjusting the modulating device responsive to actuation of the direct injection injectors, wherein operation of the modulating device is varied responsive to variation of direct injection fuel injector actuation.

A one-piece shotgun is configured to absorb impact energy when a front of the vehicle is impacted. The shotgun comprises an upper portion, a mid portion, and a lower portion, the upper portion having an end configured to connect to a hinge pillar; and a Z-trigger formed by two indentations and being located adjacent the upper portion end. The indentations of the Z-trigger are located on an outer side and an inner side of the shotgun to cause substantially lateral bending when sufficient force is applied to the shotgun.

An air extraction apparatus for automotive vehicles opens an air flow path through the passenger compartment of the vehicle when wind throb conditions are sensed in the operation of the vehicle. The air extraction opening is located in a rear facing surface of the vehicle and is covered by a closure member that is movable by an actuator to selectively open the air extraction opening. The air extraction opening can be variable in cross-sectional area through the operation of the closure member to vary the rate of air flowing through the passenger compartment. The actuator is operatively coupled to a sensor that can sense wind throb conditions to affect an automatic opening of the air extraction opening. Wind throb conditions can be the existence of a single open window coupled with a minimum operating speed, or a threshold interior air pressure within the passenger compartment.

A vehicle frame sub-assembly including a hinge pillar assembly and A-pillar assembly. A high strength hinge pillar reinforcement and A-pillar reinforcement are provided to increase the support in roof crush tests. Collision impact loads are transferred through an upper load path, lower load path, upper intermediate load path, and lower intermediate load path. A back-up rail receives loads from the front rail. The back-up rail transfers loads to the rocker and through a back-up rail extension to the hinge pillar assembly. An upper intermediate load path transfers loads from the upper rail through a fork rail to the hinge pillar assembly.
