Engine Valve Actuation Control System

View page
US Patent:
58733353, Feb 23, 1999
Filed:
Jan 9, 1998
Appl. No.:
/005632
Inventors:
Danny O. Wright - Cobb's Creek VA
James A. Nitkiewicz - Newport News VA
Assignee:
Siemens Automotive Corporation - Auburn Hills MI
International Classification:
F01L 904
US Classification:
123 9011
Abstract:
There is shown an electric motor control of the engine valves of an internal combustion engine. A brushless torque actuator controls the rotation of a cam member which provides the appropriate lift to the engine valve to move the valve from the closed to the open position. The electronic control which is connected to the actuator includes a look-up table for controlling the timing of the engine in accordance with the operation of the internal combustion engine. The electronic control operates to return the cam member to its home position closing the engine valves.

Electromagnetic Actuator With Improved Lamination Core-Housing Connection

View page
US Patent:
61572772, Dec 5, 2000
Filed:
Dec 3, 1998
Appl. No.:
9/204174
Inventors:
Dennis Bulgatz - Williamsburg VA
James A. Nitkiewicz - Newport News VA
Robert W. McFarland - Newport News VA
James P. Fochtman - Williamsburg VA
Assignee:
Siemens Automotive Corporation - Auburn Hills MI
International Classification:
H01F 708
US Classification:
335220
Abstract:
An electromagnetic actuator is provided and includes upper and lower electromagnets. Each electromagnet includes a lamination core assembly comprising a plurality of individual stacked laminations. Upper and lower housings are provided, each having opposing end walls. The core assembly of the upper electromagnet is disposed between the end walls of the upper housing and the core assembly of the lower electromagnet is disposed between the end walls of the lower housing. An armature is mounted for movement between the core assemblies. Spacer structure is disposed between the core assemblies and contacts each of the core assemblies to prevent the core assemblies from moving towards each other. A pin provides a connection between a lamination core assembly and the end walls of an associated housing. Each housing has a contact surface between the end walls and each of the core assemblies includes a solid core member defining a central portion of each core assembly.

Method And Apparatus For Detecting Engine Valve Motion

View page
US Patent:
57690430, Jun 23, 1998
Filed:
May 8, 1997
Appl. No.:
8/854023
Inventors:
James A. Nitkiewicz - Newport News VA
Assignee:
Siemens Automotive Corporation - Auburn Hills MI
International Classification:
F01L 904
US Classification:
123 9011
Abstract:
A method of and apparatus for detecting engine valve motion are provided in an internal combustion engine having an electromechanical or electromagnetic valve actuator with a ferrous component that moves in a linear path with the reciprocating motion of an engine valve between its open and closed positions. The apparatus includes a stationary magnetic field source mounted in the actuator and having an axis aligned with the linear path and positioned such that, at its closest position of travel, the ferrous component alters the magnetic field flux of the magnetic field source. A sensor mounted in the longitudinal path between the stationary magnetic field source and the ferrous component and sufficiently spaced from the magnetic field source responds to an amplified change in magnetic field flux at its closest travel position, sensing the change in the magnetic field flux of the stationary magnetic field source caused by the presence and absence of the ferrous component in the closest travel position as an indicator of engine valve motion.

Fuel Injector With A Cone Shaped Bent Spray

View page
US Patent:
63089017, Oct 30, 2001
Filed:
Feb 8, 2000
Appl. No.:
9/500232
Inventors:
James Anthony Nitkiewicz - Hampton VA
James Paul Fochtman - Williamsburg VA
Assignee:
Siemens Automotive Corporation - Auburn Hills MI
International Classification:
F02M 6120
F02M 5100
US Classification:
2395339
Abstract:
An injector for high pressure direct fuel injection in an internal combustion engine is disclosed. The injector has a downstream end and a longitudinal axis extending therethrough. The injector has an outlet orifice located at the downstream end. The outlet orifice has an outlet axis oblique to the longitudinal axis. The outlet orifice discharges a circular cone-shaped spray having a spray axis co-linear with the outlet axis. A method of forming a bent circular cone-shaped spray pattern is also disclosed.

Armature Motion Control Method And Apparatus For A Fuel Injector

View page
US Patent:
58653716, Feb 2, 1999
Filed:
Jul 26, 1996
Appl. No.:
8/686936
Inventors:
Jeffrey B. Pace - Newport News VA
Vernon R. Warner - Wicomico VA
James A. Nitkiewicz - Newport News VA
Assignee:
Siemens Automotive Corporation - Auburn Hills MI
International Classification:
F16K 3108
US Classification:
239 5
Abstract:
An injector needle/armature assembly stroke is controlled so as to minimize opening and closing impact forces. The controlled motion eliminates or significantly reduces the problems associated with valve bounce, providing less acoustic emission, reduced wear, improved spray characteristics and better flow regulation. The current applied to the electromagnetic coil of the injector in accordance with a modified injector timing pulse waveform serves to reduce impact velocities at each end of the armature stroke. The waveform can be optimized for a class of injectors with a pulse width modulated waveform, repeatedly re-energizing and de-energizing the electromagnetic coil in accordance with an optimized on/off pulse train.
