Title: Starting procedure for internal combustion vessels

Abstract

A vertical vessel, having a low bed of broken material, having included combustible material, is initially ignited by a plurality of ignitors spaced over the surface of the bed, by adding fresh, broken material onto the bed to buildup the bed to its operating depth and then passing a combustible mixture of gas upwardly through the material, at a rate to prevent back-firing of the gas, while air and recycled gas is passed through the bed to thereby heat the material and commence the desired laterally uniform combustion in the bed. The procedure permits precise control of the air and gaseous fuel mixtures and material rates, and permits the use of the process equipment designed for continuous operation of the vessel.

  • A vertical vessel, having a low bed of broken material, having included combustible material, is initially ignited by a plurality of ignitors spaced over the surface of the bed, by adding fresh, broken material onto the bed to buildup the bed to its operating depth and then passing a combustible mixture of gas upwardly through the material, at a rate to prevent back-firing of the gas, while air and recycled gas is passed through the bed to thereby heat the material and commence the desired laterally uniform combustion in the bed. The procedure permits precise control of the air andmore » gaseous fuel mixtures and material rates, and permits the use of the process equipment designed for continuous operation of the vessel.« less
  • This patent describes a method of controlling the supply of fuel to an internal combustion engine, including the steps of effecting after-start fuel increasing control wherein an initial value of a fuel increment is set to a value dependent upon a temperature of the engine upon generation of a predetermined control signal immediately after the start of the engine, the fuel increment is progressively decreased from the set initial value in synchronism with subsequent generation of the predetermined control signal, and a fuel quantity corrected by the progressively decreased fuel increment is supplied to the engine, and effecting air-fuel ratiomore » feedback control, which is executed on condition that a predetermined feedback control condition is fulfilled after the start of the engine, wherein a correction coefficient has a value thereof set to a value dependent upon the concentration of an ingredient in exhaust gases emitted from the engine, sensed by sensor means arranged in an exhaust system of the engine, and a fuel quantity corrected by the set correction coefficient is supplied to the engine, the improvement comprising the steps of: (a) setting the initial value of the fuel increment to smaller values as the temperature of the engine is higher; (b) setting the initial value of the fuel increment to a predetermined lower limit if the initial value set depending upon the temperature of the engine is smaller than the predetermined lower limit; and (c) effecting the air-fuel ratio feedback control by correcting a fuel quantity to be supplied to the engine by the fuel increment together with the correction coefficient insofar as the predetermined feedback control condition is fulfilled, when the temperature of the engine is higher than a predetermined value at the start of the engine.« less
  • This patent describes a method of controlling the supply of fuel to an internal combustion engine having an intake system after starting, wherein an initial value of a fuel increment is set to a value dependent upon a temperature of the engine after starting thereof, the fuel increment is progressively decreased from the set initial value thereof at a predetermined rate, and a fuel quantity corrected by the progressively decreased fuel increment is supplied to the engine. The method consists the steps of: (a) sensing a temperature of the intake system of the engine; and (b) setting the predetermined ratemore » at which the fuel increment is progressively decreased to a larger value as the sensed temperature of the intake system is higher.« less
  • A control system employs a microcomputer, which controls the starting operation of a spark ignition type engine provided with a fuel injection system. The control system is loaded with, at least, contact information of an ignition switch for connecting an ignition device to a power supply and a starter switch for connecting a starter motor to the power supply, and an output signal of a temperature sensor for detecting the temperature of cooling water of the engine. Where the cooling water temperature is not higher than a predetermined temperature, a fuel pump which supplies pressurized fuel to an injector ofmore » the fuel injection system is started simultaneously with the closure of the ignition switch, and this fuel pump is stopped during the operation of the starter motor.« less
  • An internal combustion engine starting apparatus uses a signal from a curt sensor to determine when the engine is energized and the starter motor should be de-energized. One embodiment comprises a transmitter, receiver, computer processing unit, current sensor and relays to energize a starter motor and subsequently de-energize the same when the engine is running. Another embodiment comprises a switch, current transducer, low-pass filter, gain/comparator, relay and a plurality of switches to energize and de-energize a starter motor. Both embodiments contain an indicator lamp or speaker which alerts an operator as to whether a successful engine start has been achieved.more » Both embodiments also contain circuitry to protect the starter and to de-energize the engine. 5 figs.« less
