Title: Closed loop engine roughness control
Inventor: LEUNG CHUN-KEUNG
IPC: F02D28/00
Filed: 1979-03-09
Granted: 1982-08-31
Abstract: CLOSED LOOP ENGINE ROUGHNESS CONTROL            ABSTRACT     A closed loop engine roughness fuel control for an internal combustion engine operative to maintain the operation of the engine at a predetermined roughness level is disclosed herein.  The control measures two rotational intervals  within  each  torque  impulse  imparted  to  the engine's  crankshaft  by  the  combustion  process  and generates a speed normalized engine roughness signal indi-cative  of  the  engine's  actual roughness.   The engine roughness signal is multiplied by the engine speed and summed with a reference signal to generate a bias signal operative to modify the quantity of fuel being delivered to the engine maintaining the operation of the engine at a predetermined roughness level.  A signal indicative of the first derivative of the engine speed is also summed with the reference and roughness signal to compensate for false roughness  signals  generated  during  transient modes  of operation.  A start enrichment circuit, activated when the engine speed is below a predetermined speed, causes the roughness control to output a fixed bias signal indicative of the engine having a roughness level greater than the desired roughness level.  The fixed bias signal causes the fuel control computer to increase the quantity of fuel to the engine to enhance starting of the engine and until the engine reaches the predetermined speed.

Abstract: 31                  47,369 ABSTRACT  OF THE DISCLOSURE   A molded case current limiting circuit interrupt ter includes a pair of pivoting contact arms each supporting a contact and being connected to wiring terminals such that current flows through the contact arms in opposite direc-tions.  One of the contact arms has a movable pivot point.          A magnetic drive slot motor device is provided to generate electrodynamic contact opening force upon the contact arms during  short  circuit  conditions.   A high-speed magnetic trip device releases the operating mechanism under short circuit conditions to move the arm pivot point before the contact arms reclose.  A spring latch may be provided to latch the upper contact arm in a contact-separated position during short  circuit  conditions until  such time as the overcurrent flow through the breaker operates a thermal and magnetic trip mechanism to move an operating mechanism to the tripped position.  Alternatively, a cam may be provided which is connected by a link to the upper contact arm and positioned  such  that upon  short  circuit  conditions  the contact opening motion of the upper contact arm caused by electrodynamic repulsion forces will cause the connecting link to rotate the cam and move the armature of the magnetic trip device to actuate the trip mechanism and release the 32             47,369 operating mechanism to the tripped position, thereby pre-venting reclosing of the contact arms before the operating mechanism is able to trip.  The operating mechanism includes a bracket  to  allow normal  contact  reset yet provide  a positive  closed  contact  indication  if  the  contacts  are welded together.  An anti-rebound contact arm shock absorber is provided which is made of material having a high mechan-ical hysteresis loop to provide maximum energy dissipation.
