Problems solved by technology

In order to solve this problem, there have been Miller cycle and Atkinson cycle. The essence of this type of cycle is to make the amount of gas in the cylinder less when the compression stroke is about to start, so as to indirectly realize the process that the expansion volume is greater than the compression volume. However, these two loop structures are complex and cannot be adjusted, let alone disable such loops when necessary

Embodiment 1

[0041] Such as figure 1 The shown throttling engine includes a cylinder-piston mechanism 1 and a compression-expansion throttling unit 2. A combustion chamber 3 is arranged in the cylinder of the cylinder-piston mechanism 1. The pressure reduction expansion throttling unit 2 is connected, and the pressure reduction expansion throttling unit 2 makes the cylinder-piston mechanism 1 work according to the Miller cycle mode.

Embodiment 2

[0043] Such as figure 2 In the shown throttling engine, on the basis of Embodiment 1, the compression expansion throttling unit 2 is further controlled by the control mechanism 4 so that the cylinder-piston mechanism 1 works in accordance with the Miller cycle mode.

Embodiment 3

[0045] Such as image 3 , Figure 4 In the throttle engine shown, on the basis of Embodiment 1, the cylinder-piston mechanism 1 is further configured as a reciprocating cylinder-piston mechanism 5 or as a rotary piston-cylinder mechanism 6 .

Abstract

The invention discloses a throttling engine which comprises a gas cylinder piston mechanism and a compressing-swelling throttling unit, wherein a combustion chamber is arranged in a gas cylinder of the gas cylinder piston mechanism; an opening of a gas inlet seat of the gas cylinder piston mechanism communicates with the compressing-swelling throttling unit; and the gas cylinder piston mechanism is driven by the compressing-swelling throttling unit to work in the Miller cycle mode. The throttling engine disclosed by the invention is simple in structure and high in efficiency.

Description

technical field [0001] The invention relates to the field of thermal energy and power, in particular to a throttling engine. Background technique [0002] Traditional volumetric piston engines include reciprocating piston engines and rotary piston engines. They have a common attribute, that is, the volume of suction and the volume of expansion work are the same, which leads to the pressure in the cylinder is still very high when the expansion stroke is over. High, that is, the gas in the cylinder still has an objective ability to do work at this time. For this reason, the property that the volume of the suction and the volume of the expansion work are the same seriously affects the efficiency of this type of engine. In order to solve this problem, there have been Miller cycle and Atkinson cycle. The essence of this type of cycle is to make the amount of gas in the cylinder less when the compression stroke is about to start, so as to indirectly realize the process that the ex...
