Description
Technical field
The invention belongs to technical field of internal combustion engines, are related to a kind of combustion engine cylinder head vaporising fuel oil device.
Background technique
The power device of aircraft, automobile, hand tractor, motorcycle, generator, diesel engine etc., traditional combustion system
It is that fuel oil is injected in combustion chamber by high pressure fuel injector, air effect is real in the fuel spray of fuel oil formation and combustion chamber
Now be mixed and burned by spraying, this combustion system in the form of diffusion combustion based on.Currently, the combustion system of power device is different degrees of
There is the case where injection fuel oil bumps against combustion chamber wall surface in ground, wall surface formation one layer of the meeting in combustion chamber is denseer after fuel oil is rebuffed
Metastable mixing gas-bearing formation.This layer of dense mixing gas-bearing formation forms the soot in combustion system and exhaust gas discharge is with important
It influences.With the raising of power plant fuel oil spurts pressure and the miniaturization of cylinder diameter, this phenomenon is said more serious.In addition,
Fuel oil is spraying to be unevenly distributed in a circumferential direction, is sprayed at drop point and is accumulated or generate oil film.Head space using insufficient,
Mixer uniform spatial distribution degree is unsatisfactory, and air utilization ratio is not high, and fuel oil combustion is incomplete, leads to fuel oil oil consumption
Height, soot emissions are big.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides one kind can improve burning indoor gas flowing, improves
Air utilization ratio realizes that fuel oil gasifies more uniform mixing, reduces fuel oil oil consumption, reduce the internal combustion engine gas of soot emissions
