    摘要: Disclosed is a control device for a waste heat recovery system which enables improvement in the responsiveness of the output control for a power turbine and a steam turbine with respect to sudden changes in the inboard load. The control device for a waste heat recovery system is equipped with: a power turbine that provides drive using engine exhaust gas and a steam turbine that provides drive using steam generated with an engine exhaust gas economizer, and is equipped with a power turbine control means which controls the output of the power turbine and a steam turbine control means which controls the output of the steam turbine, and both of which drive an electrical generator by means of the power turbine and the steam turbine. The power turbine control means is equipped with: a power turbine feedback control means which calculates a control valve operation amount based on the deviation between a power turbine target value a;nd the actual power turbine output; and a power turbine feed-forward control means which extracts a control valve operation amount from a power turbine degree-of-opening command map wherein the relationship between the engine load, the power turbine output target value calculated from the engine load, and the control valve operation amount has been preset. The power turbine control means sets the degree of opening of the control valve by adding the operation amount from the feed-forward control means and the operation amount from the feedback control means.

    摘要: A method of operation of an electric turbocompounding system for a reciprocating engine comprises the steps of retrieving from the engine ECU data pertaining to engine condition, retrieving from a set of turbine efficiency data an optimum turbogenerator speed at the engine condition, setting a desired turbogenerator set speed based on the engine condition and on a speed at which turbine efficiency is deemed to be optimum, measuring an output voltage of the turbogenerator, comparing the measured voltage with a pre-determined voltage range and where the measured voltage falls outside of the pre-determined voltage range, adjusting the turbogenerator set speed to reduce or increase the output voltage to within the pre-determined voltage range. The method also takes account of sudden increase in torque demand, such as accelaration, and additional exhaust gas recirculation (egr).

    摘要: The present invention suggests the combination ( fig. 2 ) of a conventional multi-cylinder engine, conveniently a most common non-modified four cylinders Otto or Diesel engine, hereinafter called "first engine"(1), with a second piston engine, hereinafter called "second engine"(2) having a similar constructional configuration as the first engine, that is in particular:
    a) a crankshaft synchronised or in common with the first engine
    b) same valve distribution system, i.e. a twin camshaft for separately driving the inlet and the outlet valves, except that the cam profiles are opportunely modified Said second engine is however modified to eliminate or deactivate the injection as well as the ignition systems, so as to operate as simple expanding chamber, the exhaust gases of the first engine being led to flow into said chambers and further expand therein, thanks to a particular design of the second engine's cam (6,7) profiles.
    The transfer of said gases takes place through a simple new component called "capacitor"(3), which is fluidly connected, and closely mounted (see fig.2 ), to the exhaust pipe of the first engine (1) on one side, and fluidly connected to the inlet ducts of the second engine (2) on the other side, to form a common sealed volume between the two engines.
