self-priming liquid piston engine

Abstract

The invention discloses a liquid piston engine with an automatic air supply function. The liquid piston engine comprises a cold-air cylinder, a hot-air cylinder, a heater, a heat regenerator, a cooler and a power output pipe. Liquid pistons with the bottoms communicated are arranged in the cold-air cylinder and the hot-air cylinder; the heater, the heat regenerator and the cooler are sequentially connected, the hot-air cylinder is connected with the heater, and the cold-air cylinder is connected with the cooler; an automatic air supply device is arranged on the cold-air cylinder and comprises an air supply component, a driving circuit and a liquid level sensing switch, the air supply component comprises an air pump and an air supply pipeline leading to the cold-air cylinder from the air pump, the driving circuit is used for driving the air pump to supply air to the cold-air cylinder, the liquid level sensing switch is arranged in the cold-air cylinder, the driving circuit is connected when liquid level surpasses the highest lever set in the cold-air cylinder, and the driving circuit is disconnected when the liquid level does not surpass the highest level set in the cold-air cylinder. Operation performance of the liquid piston engine can be guaranteed, and power of the liquid piston engine can be ensured not to be reduced.

Description

technical field [0001] The invention relates to an engine, in particular to an automatic air supplement liquid piston engine. Background technique [0002] A heat engine, or an external combustion engine, is an external combustion closed cycle reciprocating piston heat engine. It is also called a Stirling engine because it was invented by Stirling in Scotland in 1816. Since the hot air engine avoids the problem of detonation work of the traditional internal combustion engine, low noise, low pollution and low operating cost are realized. The power and efficiency of the hot air machine are not affected by altitude, which is very suitable for use in high altitude areas. [0003] The hot chamber, heater, regenerator, cooler and cold chamber of the hot air machine are connected in sequence to form a gas channel, and the heater is heated by an external heat source so that the gas in the gas channel flows between the cold chamber and the hot chamber. The reciprocating motion betw...

Problems solved by technology

[0008] However, when the liquid piston heat engine of Document 1 is working, due to the influence of a very small part of the gas in the heat engine being dissolved in the liquid, or the influence of the slight air leakage of the heat engine itself, the volume of gas in the heat engine will decrease and cause The increase in liquid volume, although the amount of change is very small and the speed of change is very slow, most of them do not affect the normal operation of the heat generator

However, with long-term accumulation, the liquid level in the cold cylinder will rise above the set maximum liquid level, which in turn will affect the working stability and power of the heat engine.
