Oil Burner nozzle can be classified to be three types:DLLA-P, DLLA-S and A-P according to delivery chamber, all of them can entirelymeet EURO I and EURO II Emission Standard, and our new products have met EUROIII Emission Standard.

Performance of oil burner nozzle is extremely important for engine power, fuel consumption and waste gas emission. While parts processing tolerance smallerthan 2/1000 mm is akey element to guarantee nozzle performance, which can meet the tolerance setby engine maker. It's this unique technology and excellent processing which canensure complete satisfactory of customers and properly operating of nozzleunder 1500 Pa pressure and 200°C high temperature.

Injector assembly which links injection pump and engine is consisted of manyparts of injection nozzle and injector, and it is one of most importantelements to control engine performance. Its function is to inject rationedhigh-pressure fuel which produced by injection pump into engine combustionchamber by certain direction and position, making fuel atomized and mixingproperly with air to achieve optimum combustion, and then to make engine getbest dynamic characteristic, economy and low emission. Low emission, low oil consumption and high efficiency of diesel engine is based on the mixing effect of fuel in combustion chamber and air, while, good mixing effect of fuel and air depend on feature of fuel injection nozzle, that is spray of oil beam, flowing ability and atomization.

The part between the below of hole oil burner nozzle needle base and the needlenozzle is filled with fuel after needle valve closing in the end of spraying,so fuel of that part will leak into combustion chamber, which influence badlyof diesel emission and form carbon deposition. This part is called harmfulvolume, which mainly turns on the volume of nozzle delivery chamber.

According to the volume of delivery chamber, hole type oil burner nozzle can beclassified to:
1) S type injection nozzle: diameter of needle valve is 6mm or 5mm;
2) P type injection nozzle: diameter of needle valve is 4mm;
3) Injection chamber without delivery chamber: diameter of needle valve is 4mm, have no delivery chamber.

Injection nozzle without delivery chamber has less fuel remainder in the endingof spray, so there are less hydrocarbon HC in waste gas, that can reduceharmful emission to a minimum , decrease carbon deposition, and to improvediesel engine performance.
