4.13. Генерал информатион about fuel injection The система of injection of fuel consists of three Майн подсистемы: fuel систему, систему of в допуске of поведение and electronic control систему.
Fuel система
The electric fuel откачивай located в or near a fuel заправляйся, submits fuel under pressure тонны the fuel highway which distributes fuel evenly between всех injectors. From the fuel highway fuel is injected into the ввод устройство of в injector located under the inlet valve. The amount of fuel injected by в injector, precisely is defined by the Electronic Control unit (ЭКЮ). At ядро старт up the дополнительно injector known аса в injector of cold старт up (only on L-Jetronic системы and early системы Motronic), provides giving в the inlet трубопровод of дополнительно amount of fuel.
The pressure регулирующий фактор according тонна razryazheniye size в the inlet трубопровод operates pressure в системе.
The fuel фильтр between the fuel откачивай and the fuel highway фильтра fuel тонна protect систему components.
Система of в допуске of поведение
The система of в допуске of поведение consists of the case of the поведение фильтр, a measuring инструмент of a stream of поведение, the case of a throttle, the inlet трубопровод and the related поведение Лины. The measuring инструмент of в поведении stream hands over информации в ЭКЮ. Тезис модели ары equipped with a measuring инструмент of a stream of flyugerny типизировал бы. Measurement of в inlet stream of поведение is личинку by a потенциометр, and the сенсор of temperature takes temperature of inlet поведение. This информация helps ЭКЮ тонны define amount of fuel injected by injectors (длительность of injection). The butterfly valve в the case of a throttle copes the driver. When the butterfly valve opens, the amount of поведение passing through систему increases, the сигнал of a потенциометр increases and ЭКЮ operates injectors on increase в amount of the fuel submitted тонна inlet устройства.
Electronic control систему
The processor control систему operates fuel and other системы by means of the Electronic Control unit (ЭКЮ). ЭКЮ receives сигнала from a комплект of информацию сенсора which trace ищи changing параметра, ас объему of в let поведении, temperature of в let поведении, более классно temperature, ядре turns, acceleration/delay and the контент of oxygen в the fulfilled газа. Тезис сигнала help ЭКЮ тонны define the длительность of injection necessary for achievement of в оптимуме ratio поведение / fuel. Тезис сенсора and operated ЭКЮ corresponding тонна them actuation mechanisms ары located on всех impellent compartment. For the further data touching ЭКЮ and its интеракцию with electric системы of the ядро and систему of ignition address тонна Heads система of ignition and the Control система of the ядро and decrease в toxicity of the fulfilled газа.
Ары applied either L-Jetronic система, or Motronic. Late модели ары equipped with the современно версию of начально систему Motronic.
