    Abstract: Disclosed is a super-turbocharger system that increases power and efficiency of an engine. The system uses the exothermic properties of a catalytic converter to extract additional energy from exhaust heat that is used to add power to the engine. Compressed air is supplied and mixed with exhaust gases upstream and/or downstream from a catalytic converter that is connected to an exhaust manifold. The gaseous mixture of exhaust gases and compressed air is sufficiently rich in oxygen to oxidize hydrocarbons and carbon monoxide in the catalytic converter, which adds heat to the gaseous mixture. In addition, a sufficient amount of compressed air is supplied to the exhaust gases to maintain the temperature of the gaseous mixture at a substantially optimal temperature level. The gaseous mixture is applied to the turbine of the super-turbocharger, which increases the output of said super-turbocharger, which increases the power and efficiency of said engine.

The engine (1) comprises an engine body (10) equipped with a turbocharger (7), an engine rotational speed sensor (21), an acceleration opening degree sensor (24), a boost sensor (23), a turbo sensor (22), and an ECU (100) for performing post-injection control. The ECU (100) recognizes the rotational speed of the engine, the supercharging pressure, the load on the engine, and the rotational speed of the supercharger, and so performs the post-injection control that the rotational speed of the supercharger becomes equal to the target rotational speed of the supercharger calculated in the ECU (100).

  • Patent number: 7654085
    Abstract: A system of an internal combustion engine which is induced by an air flow amplifier via a turbine and centrifugal compressor, one side of which is mechanically and pneumatically connected to the turbine and the other side with an air intake of the internal combustion engine. The operation of the engine induction system can be enhanced by using an intercooler that supplies a cooled primary flow of compressed air to the air amplifier. The use of the engine induction system without a turbocharger and, hence, without hot exhaust gases, makes it possible to utilize light magnesium alloys for parts of the turbine and compressor and thus to reduce the weight of the system as a whole.

  • Patent number: 7644584
    Abstract: A method for operating an internal combustion engine includes compressing intake air using a compressor, supplying the compressed intake air to at least one combustion chamber of the engine, operating the at least one combustion chamber to output exhaust gas, and directing the exhaust gas to an inlet of a turbine configured to drive the compressor. The method also includes directing the exhaust gas from an outlet of the turbine to an exhaust system, bypassing at least a portion of the compressed intake air around the at least one combustion chamber, and adjusting a geometry of the turbine from a first configuration to a second configuration. The turbine is in the second configuration when the at least the portion of the compressed intake air is bypassed around the at least one combustion chamber.

  • Patent number: 7610757
    Abstract: An intake controller installed in a diesel engine, wherein the control part of a valve controller fully opens a bypass valve in a bypass passage when it determines that the operating state of the diesel engine is suddenly decelerated from a middle and high speed and middle and high load range. Accordingly, the control part can feed an intake air from the outlet passage side of a compressor to the inlet passage side of an exhaust turbine, and can rapidly lower the rotational speed of an exhaust turbine supercharger (20) which tends to be rotated at a high speed by inertia. As a result, since the operating state not enter a surging area while an operating point is moving, surging can be securely avoided.

  • Patent number: 7367189
    Abstract: As the integral value of power obtained by integrating supply power to the three-phase stator coil of an assist motor with respect to time becomes larger, a motor temperature becomes higher. Then, the integral value of power obtained by integrating supply power to the three-phase stator coil of the assist motor with respect to time is detected and when this detected integral value of power is equal to or larger than a first determination value, supply power to the three-phase stator coil of the assist motor is limited. Then, when this detected integral value of power is equal to or larger than a second determination value, supply power to the three-phase stator coil of the assist motor is stopped.

  • Patent number: 7032382
    Abstract: A bypass conduit (23) connects an outlet passage of a compressor (21) of an exhaust gas turbocharger (20) and an inlet passage of an exhaust turbine (22), and a bypass valve (24) is provided therein. When the operating condition of a diesel engine (1) is found to be in a low-speed and high-load region, the bypass valve (24) is controlled by means of a valve controller to adjust the bypass conduit (23) so as to open it. Then, the charge air partly flows into an exhaust conduit (4) to increase the rotational speed of the exhaust turbine (22) and hence the charge air flow rate raises the output of the diesel engine (1). Additionally, as the charge air flow rate is increased, the operating condition of a compressor (21) is prevented from approaching the surging range.
