Abstract: A vehicle system comprises an engine, a motor-generator and a controller. The engine has a combustion mode in which a part of an air-fuel mixture is combusted by spark ignition, and then the remaining air-fuel mixture is combusted by self-ignition. The controller sets a target additional deceleration based on a steering angle, when a steering wheel is turned, and sets an air-fuel ratio of the air-fuel mixture to either one of a first air-fuel ratio and a second air-fuel ratio which is on a lean side, based on an operating state, when the engine performs the combustion mode. The controller controls an ignition timing so as to generate the target additional deceleration in the first air-fuel ratio, and controls a regenerative electric power generation of the motor-generator so as to generate the target additional deceleration in the second air-fuel ratio.

Abstract: A fuel efficiency improvement device for use on each of a plurality of locomotives in a consist includes a processor configured to transmit an initialization message including an identifier and power and fuel consumption rate information for the locomotive on which it is installed to all other locomotives in the consist. One of the devices is chosen to act as a lead device. The lead device is responsible for determining alternative throttle notch settings for each of the locomotives based on the power and fuel consumption rate information in the initialization message. The lead device may be chosen on the basis of identifiers in the initialization messages such as serial numbers. The alternative throttle settings may be determined using greedy value and maximum power calculations.

Abstract: A method and system of producing electrical energy by a moving vehicle. Moving air would be introduced to the vehicle provided with a generator for producing electricity. This electricity would be transmitted to one or more storage batteries connected between the generator and the vehicle's motor. Once sufficient energy is stored in the storage batteries, the vehicle would proceed to a facility for transferring the stored electricity in the storage batteries to batteries or other storage devices provided at the facility. The vehicle's owner would then receive remuneration or credit based upon the amount of energy transferred.

Abstract: A control apparatus for a hybrid vehicle of the present invention determines whether a brake switch flag F_BKSW is “1” or not (step S101), and in the case where the brake is on (“yes”), obtains a deceleration regeneration computation value DECRGN by table retrieval from a #REGENBR table. In the case where the brake is off (“no”), it is determined whether a fuel supply cut delay time regeneration flag F_RGNFCD is “1” or not (step S104). In the case where regeneration is not performed in the fuel supply cut delay time (“no”), a deceleration regeneration computation value DECRGN is obtained by table retrieval from a #REGEN table (step S105). On the other hand, in the case where regeneration is performed in the fuel supply cut delay time (“yes”), a deceleration regeneration computation value DECRGN is obtained by table retrieval from a #RGNNFCD table (step S106).

Abstract: A control device and control method for a hybrid vehicle is disclosed having an electric storage detecting section 13 which detects a state of charge (SOC) of an electric storage device 10. A target running efficiency calculating section 14 serves as a unit to calculate a target value of a running efficiency, indicative of a proportion of a given physical quantity, in terms of a drive power rate required for driving the vehicle such that the higher the SOC detected value, the smaller will be the target value.

Abstract: An apparatus for controlling a hybrid vehicle having an internal combustion engine and an electric motor as driving sources for the vehicle, in which when it is detected that an air-fuel ratio of a supply air-fuel mixture to the engine changed to the lean side value (S44˜S46), the electric motor (2) is made operative as a motor in order to assist an output of the engine just after the detection (S47, S48). When it is detected that the air-fuel ratio of the supply air-fuel mixture changed to the rich side value (S44, S52, S53), the electric motor (2) is made operative as a generator for the purpose of the regeneration braking just after the detection (S54, S55). An output torque difference of the engine, therefore, when the air-fuel ratio of the supply air-fuel mixture changes can be sufficiently compensated without a time delay.

Abstract: A control apparatus for a hybrid electric vehicle that minimizes vehicle fuel-consumption. A fuel consumption coefficient relating to overall efficiency of a hybrid engine is calculated. An engine operating point whereat this fuel-consumption coefficient is optimized is then determined, and the engine is controlled to operate at the determined engine operating point. When such control is performed, overall engine efficiency in all operating regions can be optimized, and further improvements in fuel consumption can be realized.

The control includes an electronic control module electrically connected to a control panel. A first and second inlet manifold pressure sensor are associated with the first and second engine, respectively. An offset potentiometer is connected to the control panel. The control automatically adjusts power output of the second engine in response to the inlet manifold pressure of said first engine, the inlet manifold pressure of said second engine, and a signal produced by said offset potentiometer.

Abstract: The engine plant comprises a plurality of turbocharged combustion engines (1, 2), the charging air systems of which are interconnected by means of a closeable conduit (14). Conduit (14) is adapted to supply supplementary charging air from the charging air system of a loaded engine (1) to the charging air system of an unloaded engine (2). A stop valve (15) is provided in the conduit and is controlled in dependence on the working condition of the associated engine (2) on the basis of a comparison between the charging air pressure and the exhaust gas pressure. Said comparison of pressures is effected by means of a surveillance unit (18) accommodating a duct system with two separate branches connected with the charging air system and the exhaust gas system, respectively. The branches are connected with a common outlet and a thermosensor is provided in either branch.

Abstract: The multi-engine consists in one embodiment of a relatively large turbocharged ship's diesel engine and three smaller turbocharged auxiliary or stand-by diesel engines. The main engine is primarily adapted for propelling the ship while the auxiliary engines solely drive electric generators. In view of the rigorous demands on the security of the delivery of electricity it is desirable to operate one or more of the auxiliary engines in stand-by mode during a substantial part of the operation time of the plant, i.e. unloaded or at low load. This involves problems for the engine concerned because the charging air pressure generated by the associated turbocharger is then lower than the exhaust gas pressure.

Abstract: A load sharing apparatus and method for coupled master and slave engines having respective throttle actuators to receive initial throttle signals, and load transmitters for transmitting load signals reflecting load on the particular engine. Apparatus has a load comparison structure which receives load signals from the load transmitters of the engines and produces a differential signal reflecting comparison of the engine loads. The apparatus also includes a servo structure which receives the differential signal and produces an output signal which is a servo signal. The servo signal is transferred to the throttle actuator of the slave engine, to change the initial throttle signal to the slave engine by an amount dependent on the servo signal thus sharing loads equally between the master and slave engines.

Abstract: The apparatus includes a master control unit associated with a first locomotive and a slave control unit associated with a second locomotive. Each of the control units is identically constructed to include an electronic processor and memory. The memory includes a program which is also identical for both units. Each of the units is connected to at least a portion of a train line extending between the locomotives, and inter-unit communications are accomplished over only a single spare line within the train line. Under control of the program the control units detect the setting of the throttle in the first locomotive, and in response thereto the control units operate the throttle of the second locomotive so that the combined operation of the first and second locomotives functions at an optimum power output-to-fuel consumption ratio within a predetermined range of power levels for each setting of the throttle in the first locomotive.

Abstract: A control system equalizes the torques of a lead and a slave engine driving a common load by comparing the throttle settings of the engines and controlling the slave engine throttle with a speed signal equal to the algebraic sum of the lead engine speed signal and a control adjustment signal equal to the sum of an adjusted, selected gain times the sum of the instantaneous error signal and the integral of the error signal over an adjusted, selected reset time.

Abstract: A load sharing arrangement for a multiple engine power plant operating to supply power to a common load wherein the power output of each engine is proportional to the amount of fuel supplied thereto. A pneumatic speed setting designated by the power plant operator is directed so as to control the power output of one of the engines (master), and remotely located control system sensitive to the power output of each of the engines, adjusts the power output of the other engine (slave) so that the common load is equally shared at the designated speed setting.

Abstract: The disclosure of this invention pertains to a system for optimizing fuel consumption in an aircraft having two engines, wherein a computer is programmed to increase the fuel flow to the engine which, consequent upon a fuel flow perturbation, shows itself to be responsible for the greater acceleration of the aircraft. Direction changes resulting from unequal fuel flows to the engines are compensated for by automatic rudder control, and speed changes resulting from the fuel flow changes are compensated for by automatic speed control also acting on fuel flow, all whereby direction and speed of flight are maintained while fuel consumption is minimized.

Abstract: The method of purging entrained air or vapor from fuel stored in two or more tanks in an aircraft, and more particularly in multi-engine aircraft during crossfeed fuel delivery when the aircraft is climbing to altitude, which method consists of reversing the fuel booster pump, or pumps, in the temporarily unused tank, or tanks, while all fuel is withdrawn from one tank to supply the engines, whereby the fuel agitation produced by the reversed pump or pumps effectively frees the entrained air or vapor from the fuel to escape to atmosphere through the fuel tank vent system.
