Thats more than five times as large like the difference between a drinking straw and a fire hose.

Natural tourist attractions france. 150hp nozzles may also be called dsla 150p 764 and use 205 holes226 injectors226 um orifice. The engine tests were conducted on an instrumented single cylinder version of the caterpillar 3400 series heavy duty diesel engine. A great nozzle for those who want an increase in power these nozzles are rated up to 150hp over stock.

Bosio dlc764 nozzles these are for cars with. These nozzles operate at high injection pressure of the order of 18 mpa. Injector hole size is perhaps the most obvious injector nozzle design variable that can be used to influence the combustion characteristics of the jet.

The actual 216 injector body looks slightly different than your stock smaller nozzle injector bodies but the nozzles are all removable and interchangeable. During the combustion the emission formation has to be kept to a minimum. Typically each nozzle hole on a factory injector measures about 007 inches.

The hole angle may be from 20 degree upwards. The injector nozzle hole size and number combinations used in the experiments included 225x8 225 gm diameter holes with 8 holes in the nozzle 260x6 260x8 and 30ox6.

Compare that with the largest ones done by scheid which can be as big as 039 inches. Very strong pressure gradients are present in a modern diesel injection nozzle this causes cavitation to occur in the nozzle holes.

The number of holes varies from 4 to 18 and the size from 35 to 200 micro meters. Like countless others you may be wondering what the difference is between all of the injector sizeshole counts and surfing the internet to find the answer can often lead to more confusion.

Injector flow hole size hole number there are three specifications that you should be aware of when buying new injector nozzles. It can be shown that the average fuel air equivalence ratio at any axial location well downstream of the injector fx is proportional to d o. The first number is the number of holes in the tip while the second number is the size of the hole measured in thousandth of an inch in diameter.
