A combination injection oil beam enveloping combustor

Abstract

The invention provides a combined jet oil emulsion enveloping type combustor. The combustor comprises an air inlet side combustor body and an exhaust side combustor body. The profile structure of the air inlet side combustor body is a circular profile. The structure of the exhaust side combustor body is an oval profile. Oil emulsion enveloping guide structures are arranged at the boundaries, between the adjacent notches of oil nozzles of oil sprayers, of the air inlet side combustor body and the exhaust side combustor body. The guide structures are designed to be in an envelope line shape according to the oil emulsion number and the oil spraying direction. The combined jet oil emulsion enveloping type combustor has the advantages that by means of the enveloping type combustor, on the premise that the compression ratio and the effective volume of the combustor are not changed, the surrounding space of oil emulsion is increased, the utilization rate of the air by all oil emulsion is increased, the quick mixing effect of oil and gas in the combined side face jet process is achieved, and thus the combustion performance of an engine is improved.

Description

technical field [0001] The invention belongs to the technical field of double-opposite two-stroke internal combustion engines, and in particular relates to a combination injection oil beam envelope type combustion chamber. Background technique [0002] The combustion process of an internal combustion engine refers to the process in which the oil, gas, and chamber of the internal combustion engine work together, and it is the guarantee that the working cycle can be repeated continuously. For a two-stroke engine, the combustion process is the entire process from the closing of the intake port to the opening of the exhaust port. The performance of the engine depends on the organization of the combustion process. In order to improve the power and economy, it is necessary to adopt measures and methods to increase the rapid mixing of oil and gas and improve the conversion efficiency of heat and power. [0003] The combustion system of the double opposed two-stroke engine is diffe...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the double-opposed engine is a new type of engine. At present, the combustors researched and applied mainly adopt the combination of circular and elliptical combustors, and the number of injection holes due to the space distribution of the combustors due to the combination of opposed lateral injections. Not too much, which affects the rapid mixing of oil and gas during combined injection of twin opposed two-stroke engines
