Abstract: An expansion system utilizes external combustion of its residual warm exhaust air, in order to heat incoming compressed air. The heat of this external combustion is communicated to the incoming compressed air through a heat exchanger. The expansion system may be incorporated into an energy storage device also featuring a compressed air storage unit supplied by a compressor. Where the stored supply of compressed air is depleted, the energy storage device may continue to supply electricity on demand through operation as a heat engine, with the compressor being driven directly (e.g. on a same rotating shaft) or indirectly (via generated electrical power) by the expansion system. Multiple expanders of the same or different types (e.g. rotating, reciprocating), may be utilized in parallel and/or in series (e.g. multiple stages) depending upon the particular application. Multi-stage embodiments featuring internal combustion in low pressure stages, may be particularly suited for placement in vehicles.

Each shaft of the reducing gear has a pair of two-tooth gears reciprocally positioned at a 90 degree angle.

Abstract: A compression ignition (diesel) engine uses two or more fuel charges during a combustion cycle, with the fuel charges having two or more reactivities (e.g., different cetane numbers), in order to control the timing and duration of combustion. By appropriately choosing the reactivities of the charges, their relative amounts, and their timing, combustion can be tailored to achieve optimal power output (and thus fuel efficiency), at controlled temperatures (and thus controlled NOx), and with controlled equivalence ratios (and thus controlled soot). At low load and no load (idling) conditions, the aforementioned results are attained by restricting airflow to the combustion chamber during the intake stroke (as by throttling the incoming air at or prior to the combustion chamber's intake port) so that the cylinder air pressure is below ambient pressure at the start of the compression stroke.

Abstract: In a vehicle in which an output of an engine is transmitted to a driving wheel through a transmission, an engine control device stops fuel injection of the engine, when engine rotational speed is above a preset specific fuel cut-off rotational speed while the vehicle is coasting; and restarts the fuel injection, when the engine rotational speed falls below a recovery rotational speed while the fuel injection is stopped, wherein the recovery rotational speed is below the specific fuel cut-off rotational speed. When determining that an operating state allows the stop and restart of fuel injection to be repeated, the engine control device sets a hunting-preventing fuel cut-off rotational speed based on an input shaft rotational speed of the transmission, wherein the hunting-preventing fuel cut-off rotational speed replaces the specific fuel cut-off rotational speed.

Abstract: When preignition is detected, and an engine speed is less than a predetermined value (Nex), an air/fuel ratio is enriched (S22), and then, when the preignition is detected even after enriching the air/fuel ratio, an effective compression ratio of an engine is reduced (S23), whereafter, when the preignition is detected even after reducing the effective compression ratio, a part of injection fuel is injected in a compression stroke (S24). On the other hand, when preignition is detected, and an engine speed is equal to or greater than the predetermined value (Nex), the air/fuel ratio is enriched (S31), and then, when the preignition is detected even after enriching the air/fuel ratio, a part of the fuel is injected in the compression stroke (S32). This makes it possible to effectively suppress the occurrence of preignition while maximally avoiding deterioration in emission performance and lowering in engine power output.
