Description
Technical field
The invention belongs to technical field of internal combustion engines, are related to a kind of cylinder gasification fuel oil combustion 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,

This cylinder gasification fuel oil combustion device is suitable for aircraft, automobile, hand tractor, motorcycle, generator, bavin
The power device of oil machine etc..
In contrast to the prior art, the present invention is had the advantages that：
1, for fuel oil of the invention after gasification road is injected into combustion chambers burn, the combustion flame in combustion chamber radiates gas
Cylinder body gasifies to the fuel oil for entering gasification road, and the fuel oil combustion gas after gasification enters combustion chamber by spray-hole, and
Combustion chamber and the air for entering combustion chamber are mixed and burned, so that combustion gas is fully burned, fuel oil is then continuously entered, and realization is
When gasification be combustion chamber combustion gas is continuously provided, the intensity of a fire is evenly dispersed, burning sufficiently, energy saving, no smoke pollution environment；Overcome
Existing 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 is not using
Sufficiently, mixer uniform spatial distribution degree is unsatisfactory, and air utilization ratio is not high, and fuel oil combustion is incomplete, leads to the thermal efficiency
The problem of oil consumption of low, fuel oil is high, soot emissions are big, pollution environment, waste of energy.
2, cylinder gasification fuel oil combustion device of the present invention is annular for oil duct by being arranged in cylinder block combustion chamber, or
The direct-furnish oil duct of cylinder block, it is annular for oil duct or the fuel oil of direct-furnish oil duct to entering using the combustion heat of cylinder block combustion chamber
It is heated, a little heat is only needed just to gasify rapidly immediately to fuel oil.
3, conventional needle-valve can be used in cylinder gasification fuel oil combustion device of the present invention, controls fuel oil by needle-valve body
Enter flow, can control the size of combustion chamber firepower.
4, cylinder gasification fuel oil combustion device of the present invention is by being arranged injection for the opposite face of oil duct oil inlet in annular
Spray-hole is arranged in hole or direct-furnish oil duct outlet side root difference firing angle, is injected into combustion chamber after can ensure that fuel oil gasification, enough mentions
High fuel oil combustion gas can mix with air effect, meet distributive ability, improve the wet wall phenomenon of fuel oil and fuel oil in air
Distributing homogeneity, make fuel oil gas volumetric combustion inflation, stablize, reduce oil consumption, combustion efficiency is good, increase efficiency, reduce row
It puts.
5, gasification road is arranged in intrinsic cylinder block in cylinder gasification fuel oil combustion device of the present invention, and structure is simply closed
Reason, is easily worked, and is able to achieve the burning of various liquid organic fuel instant gasifications, have preferable economic benefit, social benefit and
Ecological benefits.
