Double spark plug cylinder head assembly of heavy oil engine and aero engine

Abstract

The invention discloses a double spark plug cylinder head assembly of a heavy oil engine and an aviation engine. The double spark plug cylinder head assembly comprises a cylinder head, wherein a double spark plug formed by a spark plug I and a spark plug II is mounted on the cylinder head. The double spark plug cylinder head assembly of the heavy oil engine and the aviation engine have higher ignition energy, enable heavy oil to achieve more sufficient and efficient organization combustion particularly being matched with the heavy oil which is fully atomized and uniformly mixed, are beneficialto the efficient combustion of heavy oil and ensure reliable and safe ignition of an engine under various working conditions and conditions; and the size and weight of the engine are further reducedcompared with a traditional heavy oil compression-ignition type engine, the double spark plug cylinder head assembly of the heavy oil engine and the aviation engine are suitable for use by unmanned aerial vehicles and is more efficient and environmentally friendly.

Description

Technical field [0001] The invention relates to an engine and its application, in particular to a dual spark plug cylinder head assembly of a heavy oil engine and an aero engine. Background technique [0002] As the fuel of the engine, heavy oil will become the power trend of small and medium-sized drones; however, heavy oil has high viscosity and poor low temperature fluidity, resulting in a poorer atomization effect than ordinary light oil, affecting the combustion effect, and even causing difficulty in starting the engine. The emission is not up to standard. [0003] In the prior art, in order to ensure good atomization and start-up of heavy oil engines, it adopts carburetor + auxiliary preheating technology, mechanical injection (fuel direct injection), electronic fuel injection and other fuel supply methods; traditional heavy oil engines The compression ignition combustion method is basically adopted, which requires the cylinder body to bear greater pressure, thereby increasi...

Problems solved by technology

[0002] As the fuel for the engine, heavy oil will become the power trend of small and medium-sized UAVs; however, heavy oil has high viscosity and poor low-temperature fluidity, resulting in a worse atomization effect than ordinary light oil, affecting the combustion effect, and even making it difficult to start the engine and Emissions are not up to standard

[0003] In the prior art, in order to ensure that the heavy fuel oil engine can have good atomization and start-up, there are fuel supply methods such as carburetor + auxiliary preheating technology, mechanical injection (fuel direct injection), electronically controlled fuel injection, etc.; traditional heavy fuel oil engines The compression ignition combustion method is basically adopted, which requires the cylinder to bear a large pressure, thereby increasing the overall weight of the cylinder. The bulky body is not suitable for small flying machines such as drones; at the same time, it is impossible to achieve efficient combustion of heavy oil. It also makes the power, economy and emission of heavy oil applied to the engine unable to achieve the desired effect, so that the application of heavy oil cannot be widely popularized
