Sprays Injector, the Appointment of a Device

Sprays nozzle - a mechanical device designed to spray a fuel injector and diesel engines. Gasoline or diesel fuel supply is then carried out under high pressure. Remarkably, for gasoline engines it produces atomization pressure of 3-5 atmospheres, while on diesel injection is carried out at 1000-1200 atm.

What is it for? This item performs several functions in the fuel supply system. Firstly, it dispenses the right amount of fuel injected. Second, the sprayer nozzle (KAMAZ-5460 as well) perform control function and cooking fuel jet. And thirdly, the device separates itself from the injection system of the engine combustion chamber.

Often, modern diesel injector water atomizer nozzle consists of one or two channels (nozzles), through which fuel is supplied to the output and subsequently sprayed into the combustion chamber. The qualitative part should ensure the smooth conical spray of liquid. Species At the moment, there are only two types of mechanisms: Pin device and Multi-jet. In the first case, the nozzles used in nebulizers Pin mechanisms vortex and diesel engines. Multi devices are supplied with most cars having direct fuel injection, including machines with "Common Ryle" systems. Both mechanisms have their own design features however, their working principle and main function remains the same.

When the nozzle sprays are in the open position, fluid is injected into the combustion chamber. From its quantity and quality of feed it depends on so many factors, ranging from the engine power and fuel consumption of finishing. If spraying is going wrong, the car starts to smoke, lose momentum and thus consume more fuel. There is a constant rope wheel nozzle, which can lead to complete failure of its failure. Sealing device in a closed state provides a tight fit of the needle tip into the saddle gun body. When the injector nozzles are in the closed position, this special needle is held by a spring which acts on the closure cone of the device. Also worth noting is that the injection "Common Ryle" instead of the spring applied pressure very flammable liquid.
