Patent
Fuel injector and check-valve
TL;DR: In this paper, a unit injector with a flat circular valve disk having a plurality of equally spaced holes located in a ring closely inward of the ledge of the associated valve cage and closely outward of the orifice or delivery opening of an associated valve seat is considered.
Patent
Electronically-controlled late cycle air injection to achieve simultaneous reduction of NOx and particulates emissions from a diesel engine
Ramesh B. Poola,Richard J. Lill,Paul Gottemoller,Keith E. Solomons,Michael Barry Goetzke,Richard Wayne Tupek +5 more
TL;DR: In this paper, an electronically controlled air injection system implemented in three different embodiments with respect to each cylinder is presented. But the authors do not specify the parameters of the air injection systems, only that the air is supplied through an air solenoid to the air passage.
Patent
Diesel injection igniter and method
Paul Gottemoller,Richard Wayne Tupek,Michael Barry Goetzke,Polen Jerry Van,David Corba,Wojciech T Pierga,Donald E Meyer,Richard J. Lill,Hassan Z Hannon +8 more
TL;DR: In this article, an electrically-conductive injection valve is installed in a conductive nozzle body and seatable on a valve seat to stop fuel flow through nozzle orifices.
Patent
Variable injection rate high pressure fuel pump
TL;DR: In this article, a high pressure fuel pump with variable fuel injection rate is described, where a pump body, a pump cylinder formed in the pump body and a piston reciprocable within the pump cylinder defines a pressurization chamber, which is selectively open or closed passively by pump piston movement and/or dynamically by operation of an actuation solenoid valve.
Patent
Electronically-controlled air injection system for an internal combustion engine
