  • Patent number: 7174714
    Abstract: Turbocompound systems can be used to affect engine operation using the energy in exhaust gas that is driving the available turbocharger. A first electrical device acts as a generator in response to turbocharger rotation. A second electrical device acts as a motor to put mechanical power into the engine, typically at the crankshaft. Apparatus, systems, steps, and methods are described to control the generator and motor operations to control the amount of power being recovered. This can control engine operation closer to desirable parameters for given engine-related operating conditions compared to actual. The electrical devices can also operate in “reverse,” going between motor and generator functions. This permits the electrical device associated with the crankshaft to drive the electrical device associated with the turbocharger as a motor, overcoming deficient engine operating conditions such as associated with turbocharger lag.

    Abstract: An engine includes a crankshaft, rotating about a crankshaft axis of the engine. A power piston is slidably received within a first cylinder and is operatively connected to the crankshaft via first linkage system. The power piston reciprocates through a power stroke and an exhaust stroke of a four stroke cycle during a single rotation of the crankshaft. A compression piston is slidably received within a second cylinder and operatively connected to the crankshaft via second linkage system. The first and second linkage systems share no common mechanical link. The compression piston reciprocates through an intake stroke and a compression stroke of the same four stroke cycle during the same revolution of the crankshaft. The power piston leads the compression piston by a phase shift angle that is substantially equal to or greater than zero degrees and less than 30 degrees.

  • Patent number: 6609371
    Abstract: A four stroke cycle internal combustion engine including a crankshaft, rotating about a crankshaft axis of the engine. A power piston is slidably received within a first cylinder and operatively connected to the crankshaft such that the power piston reciprocates through a power stroke and an exhaust stroke of a four stroke cycle during a single rotation of the crankshaft. A compression piston is slidably received within a second cylinder and operatively connected to the crankshaft such that the compression piston reciprocates through an intake stroke and a compression stroke of the same four stroke cycle during the same rotation of the crankshaft. The power piston reciprocates along a first piston-cylinder axis which is offset from the crankshaft axis. The offset substantially aligns a point of maximum combustion pressure applied to the power piston with a point of maximum torque applied to the crankshaft during the power stroke.

  • Publication number: 20030056510
    Abstract: A hybrid vehicle having a hydrogen powered internal combustion engine employing a cylinder deactivation strategy during idle or light load conditions. A continuous stream of air is supplied to the hydrogen internal combustion engine. A control system responsive to engine speed and accelerator pedal position calculates a specific amount of hydrogen to inject into the continuous air stream. The resulting stream is combusted in the engine to provide power to the vehicle. During idling or light load conditions, the hydrogen supply to one or more cylinders may cease while maintaining the flow of air to the cylinders. A rechargeable battery and an electric motor receiving power from the battery are used to supplement the hydrogen powered internal combustion engine.

  • Patent number: 6516615
    Abstract: A system for an automobile has a compressed fuel source (14) having a first fuel pressure. An expansion device (26) is coupled to the compressed fuel source (14) and reduces the first pressure to a second pressure lower than the first pressure. The expansion device (26) generates a first quantity of work and forms a reduced pressure fuel. A chemical energy conversion engine (16) is coupled to the expansion device (26) and receives a reduced pressure fuel. The chemical energy conversion engine (16) generates a second quantity of work in response to the decompressed fuel. In one aspect of the invention, the first quantity of work and the second quantity of work may be coupled to an output shaft (20) such as the crankshaft of an internal combustion engine. In another aspect of the invention, the first quantity of work may be coupled to an accessory (40) either directly or indirectly. Indirect coupling may, for example, be performed using an accessory drive belt of the internal combustion engine.
