Problems solved by technology

[0002] The efficiency problems and pollution emission problems of volumetric power mechanisms represented by gasoline engines and diesel engines have not been well resolved. The fundamental reason is that their timing combustion methods and the volume changes in the compression process and expansion process are the same. These two major problems are caused by the basic structure of this type of engine, which cannot be changed, so a new type of engine needs to be invented

Embodiment 1

[0050] A volumetric split engine such as figure 1 As shown, it includes a volumetric compression unit 1, an internal combustion combustion chamber 2 and an expansion work unit 3. The volumetric compression unit 1, the internal combustion combustion chamber 2 and the expansion work unit 3 are connected in sequence, and the internal combustion combustion chamber 2 The volume is greater than 1.5 times the single discharge volume of the positive displacement compression unit 1, and the swallowed volume per unit time of the expansion work unit 3 is greater than 1.2 times the discharge volume per unit time of the positive displacement compression unit 1.

[0051] As a changeable embodiment, the volume of the internal combustion chamber 2 can be selectively made greater than 1.6 times, 1.7 times, 1.8 times, 1.9 times, or 2.0 times the single discharge volume of the positive displacement compression unit 1 2.1 times or more, 2.2 times or more, 2.3 times or more, 2.4 times or more, 2.5...

Embodiment 2

[0054] A volumetric split engine comprising Embodiment 1, the volume at the end of the expansion of the expansion work unit 3 discharged per unit time is greater than the volume swallowed per unit time of the volumetric compression unit 1 .

[0055] As a transformable embodiment, on the basis of Embodiment 1 and its transformable embodiment and Embodiment 2, the expansion work unit 3 can be further selectively set as a volume expansion work unit or as a speed type Expansion work unit.

Embodiment 3

[0057] A kind of displacement type split engine comprising embodiment 1, such as figure 2 As shown, the displacement type split engine also includes a turbocharger 4, the working medium outlet of the compressor 41 of the turbocharger 4 communicates with the working medium inlet of the volumetric compression unit 1, and the turbocharger The working medium inlet of the turbine 42 of the supercharger 4 communicates with the working medium outlet of the expansion work unit 3 , and an intercooler 5 is provided at the working medium outlet of the compressor 41 .

[0058] As a changeable implementation, the changeable implementation of embodiment 1 and embodiment 2 and its changeable implementation can further make the displacement type split engine further include a turbocharger 4, and the turbocharger The working medium outlet of the compressor 41 of the device 4 communicates with the working medium inlet of the volumetric compression unit 1, and the working medium inlet of the tu...

Abstract

The invention discloses a volume type division engine. The volume type division engine comprises a volume type compression unit, an internal combustion chamber and an expansion acting unit which are communicated in sequence. The volume of the internal combustion chamber is 1.5 times larger than the one-time discharge volume of the volume type compression unit. The unit time input volume of the expansion acting unit is 1.2 times larger than the unit time discharge volume of the volume type compression unit. The volume type division engine has less components, is low in cost and stable in operation, has high power density and efficiency and can be applied to various kinds of fuels.

Description

technical field [0001] The invention relates to the field of thermal energy and power, in particular to a volumetric split engine. Background technique [0002] The efficiency problems and pollution emission problems of volumetric power mechanisms represented by gasoline engines and diesel engines have not been well resolved. The fundamental reason is that their timing combustion methods and the volume changes in the compression process and expansion process are the same. These two major problems are caused by the basic structure of this type of engine, which cannot be changed, so a new type of engine needs to be invented. 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: A volumetric split engine, including a volumetric compression unit, an internal combustion combustion chamber, and an expansion work unit, the volumetric compression unit, the internal combusti...
