  • Patent number: 10527007
    Abstract: This invention relates to improvements in internal combustion engines. More particularly it relates to increased levels of usable electrical energy production and fuel efficiency within a relatively fixed speed, cam-track style Engine/Generator when combined with the secondary injection or injections of a rapidly expanding medium (usually water) into the engines combustion chambers during and after the combustion process has been initiated. The injection of said medium causing reduced fuel consumption, increased cylinder pressure, an extended usable piston stroke length, and increased usable energy production, while reducing the temperature of the combustion gases in order to control or eliminate the production of the pollutant, NOx and to further reduce thermal pollution exhausted into the atmosphere.

    Abstract: Fuel management system for efficient operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder of the engine. A fuel management microprocessor system controls injection of the anti-knock agent so as to control knock and minimize that amount of the anti-knock agent that is used in a drive cycle. It is preferred that the anti-knock agent is ethanol. The use of ethanol can be further minimized by injection in a non-uniform manner within a cylinder. The ethanol injection suppresses knock so that higher compression ratio and/or engine downsizing from increased turbocharging or supercharging can be used to increase the efficiency or the engine.

In other embodiments, the composition of the anti-knock fluid is modified, such as by using a higher octane fluid, or through the addition of water to the anti-knock fluid. In other embodiments, the replenishment interval is increased through a larger anti-knock fluid storage capacity.

    Abstract: A diesel engine for combusting a diesel-LPG mixture includes a fuel system for supplying diesel and LPG. The mixture is obtained by combining the fuel flow from a LPG tank and diesel tank. Increased pressure is applied in both fuel flows for mixing purposes. Immediately following the mixing a circulation system is present in which increase in pressure also takes place, wherein a part of the mixture is supplied to a high-pressure pump for injection to the diesel engine and a part is recirculated. In a method of supplying the diesel-LPG mixture, the part of the mixture that is supplied to the high-pressure pump is returned to a position upstream of the mixing point. The pressure in the fuel system is higher downstream of the mixing point. When the LPG supply is switched off the pressure can be gradually decreased through circulation.

  • Patent number: 8904994
    Abstract: An ammonia burning internal combustion engine can feed ammonia and a highly combustible substance burning easier than ammonia to a combustion chamber. When the amount of ammonia fed into the combustion chamber is increased or when the ratio of the amount of the ammonia to the total amount of the ammonia and the highly combustible substance fed into the combustion chamber is increased, the operating parameters of the internal combustion engine are controlled so the air-fuel mixture fed into the combustion chamber is made easier to burn. As a result, an ammonia burning internal combustion engine designed to suppress a drop in combustibility of auxiliary fuel due to ammonia, can be provided.

  • Patent number: 8903630
    Abstract: Methods and systems are provided for fuel systems including a gaseous fuel. Temporary flow restrictions in the fuel line of a first gaseous fuel may be addressed by temporarily shifting to cylinder operation with a second liquid fuel. Upon resumption of first fuel operation, if the flow restriction persists, a diagnostic code may be set and cylinder operation with the second fuel may be restarted.

  • Patent number: 8893665
    Abstract: An engine system for determining an alcohol concentration in fuel is disclosed. In one example, engine throttle position, fuel pulse width, and air-fuel ratio form a basis for determining alcohol concentration of a fuel combusted in an engine. The system and its related method may improve engine operation in conjunction with detecting an alcohol concentration of a fuel.

  • Publication number: 20140338645
    Abstract: If the pressure in a supply passage drops at a speed greater than a first determination speed in a state in which a first mode for supplying gas fuel to an internal combustion engine is selected, a control apparatus inhibits selection of the first mode. Then, the control apparatus switches from the first mode to a second mode, in energy other than gas fuel is used. In this state, if the pressure in the supply passage drops at a speed greater than a second determination speed, the control apparatus maintains the state in which the second mode is selected. If the pressure in the supply passage drops at a speed lower than the second determination speed, the control apparatus cancels the inhibition of selection of the first mode when it is detected that a manual on-off valve is opened.

  • Patent number: 8882071
    Abstract: A system and attendant structural components for incorporating an alternate fuel supply, such as of the type used in combination with a conventional distillate fuel, to power a heavy duty industrial vehicle, such as a mine haul dump truck. The system and attendant structure includes a mounting assembly structured for containment and support of the alternate fuel and a containment area disposed on the vehicle and structured and dimensioned to retain the mounting assembly therein. The containment area and the mounting assembly are disposed in laterally adjacent, exposed relation to an operator area of the mine haul truck, wherein the mounting assembly and the containment area are cooperatively disposed and structured to facilitate storage of the alternate fuel and operative communication and distribution thereof with the powering engine of the mine haul vehicle.

  • Patent number: 8875666
    Abstract: A process for operating an internal combustion engine or a nozzle includes producing a fuel mixture in-situ. The fuel mixture consists of a polar component A, a nonpolar fuel component B, an amphiphilic component C, and an auxiliary component D. The fuel mixture is produced in a high-pressure region of an injection system of an internal combustion engine or of a nozzle within 10 seconds of an injection operation. The fuel mixture is injected into the internal combustion engine or the nozzle. A pressure is in a range of from 100 to 4,000 bar.
