Title: High-pressure gaseous fuel injection
Inventor: POPP ROGER C
IPC: F02M47/04
Filed: 2001-01-04
Granted: 2007-05-01
Abstract: A high-pressure fuel injection system for injecting high-pressure gaseous fuel from a gaseous fuel supply into cylinders of an engine. The injection system comprises an oil reservoir of hydraulic oil, a hydraulic oil supply of hydraulic oil at a pressure higher than the oil reservoir, and a gas/oil separator located in a safe location remote from the cylinders of the engine. The gas/oil separator is adapted to separate any gaseous fuel from the hydraulic oil, and return the separated oil to the oil reservoir. A plurality of high-pressure, fuel-injector valve assemblies inject fuel into the cylinders of the engine; each fuel-injector valve assembly including an electrohydraulic valve and a fuel injector. The electrohydraulic valve is connected to the high-pressure hydraulic oil supply, the oil reservoir and an electronic controller providing electrical control signals, and the electrohydraulic valve creates successive hydraulic signals in response to electrical control signals. The fuel injector includes a fuel valve operated by a piston, and an outlet port in communication with the gaseous fuel supply. The piston reciprocates the fuel valve in response to hydraulic signals to open and close the outlet port, and thereby successively injects gaseous fuel into the cylinder. Each fuel- injector valve assembly further includes means for collecting leakage of oil and leakage of gaseous fuel, and communicates any such leaked oil and leaked gas to the gas/oil separator.

Granted: 2010-06-15
Abstract: A system for controlling operation of a progressing cavity pump to maintain the motor operating under power disturbance conditions. For a blackout condition, a backspin controller uses regenerative power to provide controlled deceleration of the pump, counteracting backspin and preventing backspinning freely. For a brownout condition, a power dip controller weakens the motor field to maximize pump production consistent with reduced input power availability. For a phase loss or voltage imbalance condition, a phase loss controller reduces motor power output to keep drive system output power at or below single phase capacity.
