  • Aneroid boost modulator
    Patent number: 5218940
    Abstract: An aneroid boost modulator briefly restricts mass air flow from a turbocharged diesel engine intake manifold to a fuel injection pump aneroid control during free engine acceleration to inhibit operation of the aneroid controller until the engine and the turbocharger develop sufficient speed to use the increasing fuel supply efficiently. The modulator eliminates emission of black smoke from the engine during free engine acceleration while having no significant affect on acceleration of the engine under a load as in accelerating a vehicle.
