A method for generating power, comprising the steps of: a) providing a Rankine Cycle device that includes a plurality of turbo-generators, each including a turbine coupled with an electrical generator, and at least one of each of an evaporator, a condenser, and a refrigerant feed pump; b) disposing the one or more evaporators within an exhaust duct of a power plant of a marine vessel; c) operating the power plant; and d) selectively pumping refrigerant through the Rankine Cycle device.

This disclosure outlines a method, which enables a vehicle driver to achieve increased fuel efficiency by implementing least-cost route planning based on terrain data and derived from advanced mapping, logging and location based services. Actual fuel efficiency is recorded and correlated by vehicle conditions, time of day and date, and then referenced to achieve the most accurate least-cost route plan for the intended destination.

In a fuel container (1) for a motor vehicle having a plurality of chambers (2, 4), a suction jet pump (18, 19) with a filling level sensor (11, 12) is arranged in each of the individual chambers (2, 4). A valve (24, 25) is arranged in a propellant line (20, 21) leading to the suction jet pump (18, 19). When a chamber (2, 4) is virtually empty, the supply of fuel to the suction jet pump (18, 19) is disabled and an unnecessary movement of the fuel is thus avoided.

An engine (400) is disclosed and comprises: a compressor (428) which periodically defines a chamber and carries out a pressurization process wherein the chamber volume is decreased to produce pressurized air; a combuster (426) which combusts fuel with the pressurized air to produce primary exhaust; an air motor (408) which is driven by the primary exhaust to produce power and secondary exhaust; an expander (410) which expands the secondary exhaust to produce tertiary exhaust and power; and a shaft (314) which directs power produced by the motor (408) and the expander (410) to the compressor (428) and any load. The combuster (426) is adapted to receive varying amounts of fuel, thereby to vary the power to the load. The compressor (428), during pressurization. releases air from the chamber such that the chamber pressure during pressurization and the primary exhaust pressure is substantially constant at steady state conditions, said constant being a function of the load being driven by the power.

In order to improve the transfer of heat from a warm fluid inside a heat exchanger tube (333) including an elongated tube with a wall with an exterior surface and an interior surface, the interior surface is provided with at least one longitudinally extending interior wall (363′, 363″) which extends from one side of the interior surface towards another side of the interior surface.

A system is described for improving engine and vehicle performance by considering the effects of exhaust conditions on catalyst particle growth. Specifically, engine operation is adjusted to reduce operating in such conditions, and a diagnostic routine is described for determining the effects of any operation that can cause such particle growth. Further, routines are described for controlling various vehicle conditions, such as deceleration fuel shut-off, to reduce effects of the particle growth on emission performance.

In a method for producing a hollow body—implemented as a sandwich construction—in particular an aircraft fuselage, an inner layer is formed from a specifiable number of plies of a specifiable at least resin-wetted fiber material, for simple, rapid, and cost-effective formation of a large-volume cavity, which has a low weight and a high mechanical carrying capacity in relation to its size. At least a first ply of the inner layer has a helical configuration and is configured without interruption essentially over an entire length of the hollow body.

A propane tank fuel gauge for use with a barbecue grill that measures the weight of the tank and thereby provides a readily perceived indication of the amount of propane gas remaining therein. The fuel gauge comprises a base, a tank mount adapted for mounting a propane tank, a spring-loaded support mechanism for supporting the tank mount relative to the base, and a fuel level indicator connected to the support mechanism for providing an indication of the total weight of the tank including the propane gas remaining therein.

A diesel engine exhaust gas aftertreatment system is described. The system may comprise a heat transfer device comprising a first side and a second side; a heater downstream of the first side of the heat transfer device, a filter downstream of the heater; and, an exhaust path downstream of the filter leading to the second side of the heat transfer device, wherein the exhaust path is isolated from an external surface of the filter to inhibit heat transfer from the heated exhaust gas exiting the filter to the external surface of the filter.

A method and a system for operating an eight-stroke internal combustion engine having higher thermal efficiency than a four-stroke engine is disclosed. The strokes comprise intake (FIG. 1), compression (FIG. 2), combustion for a first power stroke (FIG. 3), exhaust (FIG. 4), vapor or water injection for a second power stroke (FIG. 5), exhaust (FIG. 6), vapor injection for a third power stroke (FIG. 7), and exhaust (FIG. 8). Heat from each exhaust is recovered and recycled to a subsequent stroke. Consequently, an engine with much higher thermal efficiency and thus lower fuel consumption is achieved.

An internal combustion engine 10 comprises a spark plug 70 which has a spark generation part 71, and a partition wall part 80. The partition wall part 80 partitions a combustion chamber CC into a main combustion chamber CM and an ignition chamber CI. The combustion chamber is defined by a cylinder bore wall 21, a piston crown surface part 31 and a cylinder head wall 41. The cylinder bore wall and the piston crown surface part are exposed to the main combustion chamber, and the spark generation part is exposed to the ignition chamber. “A through hole 81 and a through hole 82” are formed in the partition wall part such that the main combustion chamber and the ignition chamber are in communication with each other. Flame is generated in the ignition chamber when combustion of fuel-air mixture is started by a spark generated from the spark generation part in the ignition chamber. The flame is ejected from the ignition chamber into the main combustion chamber through the first and second through holes. Distance between the first through hole and the cylinder bore wall is longer than distance between the second through hole and the cylinder bore wall. The first and second through holes are formed such that penetration of the flame ejected from the first through hole is larger than penetration of the flame ejected from the second through hole.

A coupling member for connecting a part, provided for receiving or dispensing fuel and made primarily of HDPE (high-density polyethylene), to a fluid line has first, second, and third components made of meltable material. The third component forms a heat fusion joint with the part for receiving or dispensing fuel and has an undesirably high permeability and swelling capacity relative to fuel. The third component is connected to the first component by material bonding and positive-locking action. The second component has greater fuel blocking capacity and higher strength than the third component. The second component is embedded in the third component. A volume ratio of second and third components is selected such that combined properties of the second and third components concerning permeability, strength, and volume changes by swelling are approximated to these same properties of the second component. The first and third components are heat-fusible to one another.
