Description
Technical field
The present invention relates to a kind of hybrid power system, more particularly to it is a kind of with double mode homogeneity compression-ignition (HCCI,
Homogenous Charge Compression Ignition) internal combustion engine as major impetus originate and with mechanically connect,
Power circuit is as energy transmission medium and is integrated with the mixing of motor/generator, electrokinetic cell unit and its control technology
Power-driven system and hybrid power control method and automobile.
Background technology
Because traditional combustion engine only could obtain preferably fuel economy in less high load capacity operating point, and daily life
In work, the motor vehicles using internal combustion engine as main power source are most frequently operated under underload or idling operation and Fraquent start, because
And it is high to integrate oil consumption.Homogeneity compression-ignition formula internal combustion engine under compression-ignition mode than traditional internal combustion engine have higher fuel economy and
Lower discharge, but its stable, efficient operation area scope is smaller, is concentrated mainly on middle low speed and load operating mode, therefore it is defeated
Torque capacity/the power gone out is much smaller.Although using dual combustion mode switching the power output upper limit can be expanded, pattern it
Between switching transient response is poor, variable working condition ability deficiency the problems such as govern it and substitute existing traditional Vehicular internal combustion engine and carry out
Large-scale promotion is used.
The internal combustion engine that existing hybrid power system is typically circulated using traditional spark ignition type Otto circulations or Atkinson, this
Operating efficiency of the class internal combustion engine in slow-speed of revolution running on the lower load region is poor, in order to ensure the greater efficiency of hybrid power system,

The scheme of the hybrid electric vehicle of combustion engine, these schemes using HCCI internal combustion engines as major impetus output source, internal combustion engine and wheel it
Room machine is connected, and changes of traveling road conditions is directly reflected as the change of internal-combustion engine rotational speed/load, this variable working condition sound to internal combustion engine
There should be at a relatively high requirement, but HCCI internal combustion engines ability in terms of this is not enough, even if being born using internal combustion engine
Lotus adjust, frequent, quick working conditions change easily cause HCCI internal combustion engines because combustion start time hardly possible control caused by catch fire,
The unstable phenomenon of the operation such as pinking, operating efficiency declines to a great extent, deterioration of emission.In addition, HCCI internal combustion engines compare the biography with discharge capacity

The hybrid power system of internal combustion engine, the concrete structure for the hybrid power control method realized using the hybrid power system, control
Flow processed, feature and advantage etc., but all descriptions are intended merely to what is illustrated, and should not be construed as to the present invention
Form any limitation.In addition, any single technical characteristic for being described by or implying in the mentioned each embodiments of this paper, or
Shown or implicit any single technical characteristic in the drawings, still can be between these technical characteristics (or its equivalent)
Proceed to be combined or delete, so as to obtain other the more implementations of the invention that may do not referred to directly herein
Example.
In addition, beyond unless specifically stated otherwise, there is such as low speed, middle low speed, high speed, low negative in each place herein
These technical termses such as lotus, middle high load capacity, high load capacity, superelevation load belong to generic term of the prior art, and they contain
The implication that justice understands and grasped with those skilled in the art is consistent completely, and the implication of these technical termses is also complete
It can be readily appreciated by one skilled in the art and grasp.For example, normal duty refers to the energy steady running under HCCI combustion mode,
And the load that engine can reach when Pressure Rise Rate or maximum explosive pressure are in tolerance interval in cylinder, for example starting
Indicated mean effective pressure is typically referred in the case of machine is unpressurized for 1 ~ 5bar.And higher load refers to beyond HCCI combustion mode
The bigger load of normal duty, for example engine load is under conditions of more than 40%.
