Laval gas injection engine device

Abstract

The invention discloses a laval gas injection engine device. The engine device comprises a housing, a rotor piston located inside the housing, a primary circulating gas feeder, a primary circulating exhauster, a secondary circulating gas feeder, a secondary circulating exhauster and a secondary refrigerator, wherein a combustion chamber is arranged between the outer side of the rotor piston and the inner wall of the housing; the primary circulating gas feeder, the primary circulating exhauster, the secondary circulating gas feeder and the secondary circulating exhauster are communicated with the interior of the housing; meanwhile, a gas provided by an external device goes into the combustion chamber inside the housing via the primary circulating gas feeder, and the primary circulating gas feeder and the secondary circulating gas feeder both are connected with the secondary refrigerator. According to the device, the special process of twice closed circulating jet work is adopted and the acting efficiency is greatly improved; besides, the device is small in volume, low in cost and convenient to prepare.

Description

Technical field [0001] The invention belongs to the field of engines, in particular to an automobile engine device, and more particularly to a Laval jet gas engine device. Background technique [0002] Since the beginning of the 21st century, resource shortages and serious environmental pollution have become huge problems that plague mankind. With the progress of human civilization, the scale of cities is gradually expanding. The number of vehicles that shuttle in the city is increasing day by day, and the exhaust emissions from vehicles have become cities. The huge problem of pollution. Therefore, the development and application of clean new energy has become a topic of increasing attention. New vehicles powered by renewable clean energy such as bioenergy, solar cars and battery-powered cars have gradually entered our lives. [0003] However, for the increasingly severe crisis, these efforts are still inadequate. In order to better promote the industrialization of electric vehic...

AI Technical Summary

Problems solved by technology

[0005] 1. The production and manufacture of lithium batteries used in lithium battery electric vehicles will cause high pollution and high energy consumption. In addition, the cost of lithium batteries used in electric vehicles is also high; in addition, the charging and discharging of electric vehicles The bottleneck technology is still not fully resolved so far, resulting in high failure rate and short service life of lithium battery vehicles, and it has not been widely popularized so far;

[0006] 2. Hydrogen fuel cells have a history of decades of development, but various bottleneck technologies still cannot be resolved, resulting in the price of fuel cells beyond the reach of users, and it is difficult to be commercialized

However, the above-mentioned aerodynamic engine is reformed on the basis of a traditional reciprocating diesel engine, so the efficiency of the equipment for converting energy into mechanical energy is low, both at about 35%.
