Embodiment 1

[0044] Such as figure 1 The shown excess air engine includes a volumetric compression unit 1 and an expansion work mechanism 2, the volume compression unit 1 is in non-reheat communication with a continuous combustion chamber 3, and the continuous combustion chamber 3 is in communication with the expansion work mechanism 2 , the pressure bearing capacity of the continuous combustion chamber 3 is greater than 1.5MPa, and the mass flow rate of the compressed air flowing into the continuous combustion chamber 3 is 1.5% of the mass flow rate of the air required for fuel combustion flowing into the continuous combustion chamber 3 more than double.

[0045] As a changeable embodiment, the pressure bearing capacity of the continuous combustion chamber 3 can also optionally be set to be greater than 2.0MPa, 2.5MPa, 3MPa, 3.5MPa, 4MPa, 4.5MPa, 5MPa, 5.5MPa, 6MPa, 6.5MPa, 7MPa, 7.5MPa, 8MPa, 8.5MPa, 9MPa, 9.5MPa or greater than 10MPa.

[0046] As a changeable embodiment, the mass flow...

Embodiment 2

[0048] Such as figure 2 The difference between the excess air engine shown and Embodiment 1 is that the expansion working mechanism 2 is set as a self-expanding volume type fluid mechanism, specifically, the self-expanding volume type fluid mechanism is set as a screw fluid mechanism 211 .

[0049] As an alternative embodiment, the self-expanding volume fluid mechanism can also be changed to a scroll fluid mechanism.

Embodiment 3

[0051] Such as image 3The difference between the excess air engine shown and Embodiment 2 is that the expansion working mechanism 2 is changed to a non-self-expanding volume type fluid mechanism with a control valve 4 at the inlet, specifically, the non-self-expanding volume Type fluid mechanism is set as reciprocating cylinder-piston mechanism 221.

[0052] As an alternative embodiment, the non-self-expanding volumetric fluid mechanism can optionally be changed to a rolling fluid mechanism, a slide fluid mechanism, a rotary piston mechanism, a swing cylinder-piston mechanism or a liquid piston mechanism.

[0053] As an alternative embodiment, the non-self-expanding volumetric fluid mechanism can optionally be changed to a non-self-expanding volumetric fluid mechanism including a Wankel mechanism.

Abstract

The invention discloses an air-excess engine. The air-excess engine comprises a volume type compression unit and a swelling acting mechanism; the volume type compression unit is in non-backheating communication with a continuous combustion chamber, the continuous combustion chamber is communicated with the swelling acting mechanism, the pressure bearing capacity of the continuous combustion chamber is over 1.5 MPa, and the mass flow rate of compressed air flowing into the continuous combustion chamber is more than 1.5 times that of air needed by combustion fuel flowing into the continuous combustion chamber. The air-excess engine has the advantages that the structure is simple, the efficiency is high, and the pollutant discharge is little.

Description

technical field [0001] The invention relates to the field of thermal energy and power, in particular to an engine with excess air. Background technique [0002] Existing engines have low efficiency and serious pollution emissions, and for engines equipped with regenerators, the regenerators have disadvantages such as large flow resistance, large volume, complicated manufacturing, and high cost. Therefore need to invent a kind of novel engine. Contents of the invention [0003] In order to solve the above problems, the technical scheme proposed by the present invention is as follows: [0004] Scheme 1, an engine with excess air, comprising a volumetric compression unit and an expansion work mechanism, the volume compression unit is in non-reheat communication with a continuous combustion chamber, and the continuous combustion chamber is communicated with the expansion work mechanism, and flows into the The mass flow rate of the compressed air in the continuous combustion ...
