Inventor
In automotive engineering, an inlet manifold or intake manifold (in American English) is the part of an engine that supplies the fuel/air mixture to the cylinders. The word manifold comes from the Old English word manigfeald (from the Anglo-Saxon manig [many] and feald [repeatedly]) and refers to the multiplying of one (pipe) into many.

Vacuum enhancing check valve
InactiveUS20060016477A1Reducing vehicle 's costReduce complexityBraking action transmissionRatio controlEngineeringCheck valve
A vacuum enhancing check valve for direct connection to a vehicle brake booster which increases the partial vacuum provided thereto and restricts possible air back flow into the brake booster. The valve comprises a venturi for reducing the pressure of air induced to flow between a first air inlet and an air outlet by a partial vacuum at a vehicle engine's intake manifold. By significantly reducing the air pressure, the valve enhances the partial vacuum available for provision to the brake booster. The venturi is also in air communication with a second air inlet directly attachable to the brake booster such that the air pressure at the second air inlet tends toward the enhanced partial vacuum within the venturi. A valve seat and seal member within the valve are cooperative to allow air flow from the second air inlet toward the venturi, but not in the reverse direction.

Several calibration and control methods are described to maximize performance of the fuel system, including the use of a misfire detection technique to determine the lean misfire limit of each cylinder to allow the respective port fuel injector to provide a specified margin from lean misfire.
