摘要:
A fuel injection nozzle is provided with such an annular fuel passage that its fuel passage section is, at the earlier stage of fuel injection, maintained smaller than the whole sum of the sectional areas of injection orifices and adapted to increase gradually in response to the lift of a nozzle needle so that the rate of fuel injection increases gradually.
摘要:
An output signal of a vibration sensor mounted on an internal combustion engine is compared with a background noise reference signal to produce a knock signal which can accurately represent the intensity of knocking. The background noise level signal is produced by averaging a component of the vibration sensor output signal which represents the vibration of the engine other than knock-induced vibration. In order to produce a feedback signal for inhibiting the knock induced component of the sensor output signal, a first comparator compares the sensor output signal with a first reference signal having a sufficiently low level. Knock signal is produced by a second comparator which receives a second reference signal, which is proportional to the first reference signal but having sufficiently higher level, thereby enabling a precise determination of knock intensity.
摘要:
A knock control system and method for use in an internal combustion engine equipped with a supercharger for applying supercharge to the engine comprise detecting the frequency of occurrence of knock in the engine, and varying the degree of supercharge applied to the engine in accordance with the detected frequency of occurrence of knock.
摘要:
In an elevator control system, in which the elevator car is controlled on the basis of elevator car positions obtained through the counting of distance pulses provided in proportion to the distance travelled by the car and floor height data indicative of the heights of individual floors, the distance pulses are counted by moving the car at a low speed from the lowest floor to the highest floor, and the count at the time of the actuation of a floor position detector, which is actuated when the car passes by each floor, is stored as the floor height value of that floor in a RAM (Random Access Memory). With this arrangement, the measurement of the floor heights is facilitated, and also the preparation of a ROM (Read-Only Memory) for storing the floor height data for each elevator car is made needless to promote the standardization.
摘要:
A system for detecting the intensity of knocking of an internal combustion engine such as an automotive gasoline engine, comprising a vibration sensing device attached to an engine body and electrical circuitry for producing a knock-indicating signal based on a comparison of a vibration-indicating signal derived from the vibration sensing device with a reference signal which is variable depending on the rate of engine revolution. The vibration sensing device comprises a vibration pickup such as of an accelerometer type, preferably mounted on a resonance plate which is fixed only at its one end to the engine body, and is made to have a resonance frequency within a frequency band of vibrations attributable to knocking of the engine, such as 5 to 10 KHz, so that no band-pass filter is needed in this system.
摘要:
An elevator control system for controlling a plurality of elevator cars servicing a plurality of floors of a building by allotting a hall call originated from one of the floors to a suitable one of the elevator cars so that the hall call can be serviced by the selected elevator car. In the elevator control system, a scan signal generator is provided to generate a scan signal which is used to sequentially scan the floors in successive scan slots for detecting hall calls and elevator car service positions and converting the detected information into pulse signals. The elevator control system comprises counters for counting up the service loads of the individual elevator cars in the successive scan slots after the detection of the elevator car service positions, so that, when a hall call is detected in one of the scan slots, an elevator car providing a minimum service load at the specific scan slot can be selected, and the detected hall call can be allotted to the selected elevator car. The elevator control system of such construction may be divided into a plurality of blocks classified by their control functions. These blocks are electrically isolated from one another by isolating means which permits transmission of signals among them. In a modification, the scan signal generator may be provided in each of the blocks.
摘要:
An air-fuel ratio sensing device for an air-fuel ratio control system of an internal combustion engine, which device includes a sensing element exposed to exhaust gases passing through an exhaust gas passageway. A housing surrounding the sensing element has a plurality of openings to admit the exhaust gases into the housing, and a plurality of temperature responsive valves associated with the openings, respectively, which are closed when the exhaust gases exceed an excessively high temperature to prevent the sensing element from being deteriorated due to excessively high temperature of the exhaust gases.
