Abstract: An over ride oil pump for use with reciprocating or rotary engines which provides auxiliary oil pumping under three circumstances by use of an electrically operated oil pump, digital circuitry and sensors. As a car is started the standard mechanical oil pump cannot provide adequate lubrication since the mechanical pump can only pump at a rate proportional to engine speed. The over ride pump begins immediately, upon initiation of engine start up. Under conditions of high RPM operation extra lubrication is required. The over ride oil pump senses increased vacuum levels and provides additional oil delivery. Oil pressure drops rapidly if there is a failure in the mechanical pump drive mechanism or the pump itself. The over ride oil pump senses this deficiency and provided the necessary oil delivery.

A Hall element unit serves to sense the conducted magnetic flux and generate a first signal indicative of the actual position of the control member. A second signal indicates a desired position of the control member. A device, responsive to the first and second signals, serves to adjust the actual position of the control member to the desired position thereof.

Abstract: Fuel injection devices are used for injecting fuel into the combustion chambers of compression ignition engines. It is desirable to isolate the mechanical drive for fuel injection timing from the flow path of high pressure fuel to minimize the seepage of fuel into the fluid lubricating the mechanical drive while using only one speed responsive device for both the timing and governing functions. The subject fuel injection apparatus includes a planetary gear arrangement having a ring gear to change the timing phase relationship between a distributor rotor and a delivery passage which communicates the pump section with the rotor. A metering collar is adapted to meter the quantity of fuel delivered by the rotor to the outlet ports. Both the ring gear and the metering collar are mechanically connected to an element of a single flyweight assembly. The metering collar is widely spaced from the planetary gear arrangement to minimize the leakage of fuel into the lubricating fluid.

Abstract: Previously disclosed distributor fuel injection pumps for internal combustion engines offer the advantages of reduced size, weight, and cost of a fuel injection system. However, these pumps have not been able to provide relatively high fuel injection pressures which could improve fuel combustion for better fuel economy and lower noxious emissions. In contrast, the subject distributor fuel injection pump generates relatively high fuel injection pressures in a relatively compact arrangement. A semi-spherical nutator member freely rotatably mounted on an oblique journal of a drive shaft imparts high speed harmonic motion to at least one reciprocating pump plunger for pressurizing the fuel. A relatively large semi-spherical bearing interface between the nutator member and a pump housing accommodates very high pumping reaction loads.

Abstract: A fuel supply control method for electronically controlling the quantity of fuel being supplied to an internal combustion engine at the start of the engine, in response to values of engine control parameters including at least the engine temperature. When there is an abnormality in an engine temperature detecting means that detects the value of the engine temperature, while the engine is operating in a predetermined starting operating condition, control is effected by gradually increasing the quantity of fuel being supplied to the engine with the progress of time starting from a time the engine starter is switched on, by the use of a predetermined dummy signal indicative of engine temperature, in place of an output signal from the aforementioned engine temperature detecting means. Preferably, the value of the above dummy signal is set so as to change from a higher engine temperature value to lower engine temperature values in a successive and stepwise manner at an interval of a predetermined period of time.

Abstract: A form of insulation is disclosed that takes up less room and is more efficient than insulation currently available. It has several modes of use that make it more versatile than conventional insulation. The insulation is formed from a pair of surfaces that are sealed to each other at all edges to form an enclosed chamber, a honeycomb, a cellular matrix, or truss structure is inside the said chamber, separating the surfaces. Said chamber is evacuated and the surfaces that face the chamber are constructed to be of low emittance so as to provide an insulation that significantly inhibits the transference of heat in any manner. By using a material with a high absorbtion and low emittance on one surface and a material with high emittance and low absorbtion on the opposite surface, heat can be transferred easily in one direction but poorly in the other direction, thus acting as a thermal diode.
