Innsprøytningsdyse VAG │ Bensininnsprøyting Bosch Petrol Fuel Injector

Bosch Fuel injector - Gasoline port fuel injection The fuel injector is installed at the intake manifold injection before the inlet valve. It injects the fuel such that it builds a homogenous mixture with the added air. This air-fuel mixture is created by opening the inlet valve of the intake manifold into the combustion chamber where it is ignited by means of an ignition spark and burnt. A distinction is made between whether the injection is made prior to or during opening the inlet valves. - factor 10 reduced leakage values compared with industry-specific thresholds - versatile ethanol resistance allows worldwide use - flexible engine-specific installation and spray characteristics - low weight of about 25 g Engine-specific adjustments for reduced emissions and less fuel consumption The variant diversity in position and number of the high-precision manufactured orifices and the customer-specific adaptations to the installation of the fuel injectors effect a great fuel-mixture generation: To meet engine-specific requirements, different spray qualities are possible as well as an optimal alignment of the spray to the inlet valve, respectively the combustion chamber in connection with a controlled production of wall film in the intake manifold. With this so-called Bosch Spray Targeting, CFD simulations of the spraying behavior back up the application-specific 3D-inlet and combustion chamber geometrical data. This results in the reduction of emissions and fuel consumption. Robust fuel injectors for an international market Bosch fuel injectors feature excellent tightness that is measured by means of a special high-precision measurement technology developed by Bosch. Leakage values reduced by > factor 10 compared with the former industry-specific threshold are specified. The Bosch fuel injectors can be used all over the world as the material is also resistant against impure and aggressive fuel with a high portion of ethanol and methanol.
