(54 СПОСОБ ЗАПУСКА ДИЗЕЛЯ С НАДДУВОМ(54 METHOD OF RUNNING A DIESEL WITH SUPERCHARGING
1one
Изобретение относитс к машиностроению , в частности к двИгателёстроению, и может быть использовано при запуске дизелей с наддувом.The invention relates to mechanical engineering, in particular to gigging, and can be used when starting diesel engines with supercharging.
Известен способ запуска дизел с наддувом и пониженной степенью сжати , заключающийс в том, что прокручивают дизель от электростартера, подают воздух и топливо в цилиндр дизел и после сжати воспламен ют топливовоздушную смесь в цилиндре свечой зажигани , контрсЗлируют режим работы по одному из параметров и после достижени заданного значени этого параметра прекращают воспламенение смеси 1.A known method of starting a diesel engine with supercharging and a reduced compression ratio is that the diesel engine is rotated from the electric starter, air and fuel are fed into the diesel cylinder, and after compression, the air-fuel mixture in the cylinder is ignited by a spark plug, counter operation mode is achieved by one of the parameters and after reaching the given value of this parameter stops ignition of mixture 1.
Известный, способ позвол ет запустить дизель, однако при низких температурах окружающей среды из-за охлаждени цилиндра запуск дизел ненадежен.The known method allows starting the diesel, however, at low ambient temperatures due to the cooling of the cylinder, the starting of the diesel is unreliable.
Целью изобретени вл етс повыщение надежности запуска.The aim of the invention is to increase the reliability of the launch.
Дл достижени поставленной цели в качестве контролируемого параметра выбирают давление подаваемого воздуха, перед подачей в цилиндр топливо испар ют, а воздух подогревают, в смеси с топливом подают в цилиндр, где воспламен ют, и после достижени заданного значени давлени подаваемого воздуха прекращают испарение топлива и подогрев воздуха.To achieve this goal, the pressure of the supplied air is chosen as a controlled parameter, the fuel is evaporated before being fed into the cylinder, and the air is heated, mixed with fuel is fed into the cylinder where it is ignited, and after reaching the specified value of the supplied air pressure, evaporation of the fuel and heating are stopped. of air.
На чертеже представлено, устройство, реализующее предлагаемый способ.The drawing shows a device that implements the proposed method.
Устройство снабжено камерой 1, соединенной с рубащкой 2 впускного трубопровода 3 через теплообменник 4. На входе в камеру 1 установлен нагнетатель 5 воздуха , соединенный с электромотором 6, а в самой камере - дополнительна форсунка 7 The device is equipped with a chamber 1 connected to the jacket 2 of the intake manifold 3 through a heat exchanger 4. At the entrance to the chamber 1, an air blower 5 is installed, connected to an electric motor 6, and in the chamber itself - an additional nozzle 7
10 и свеча накаливани 8. Во впускном трубопров;оде 3, сообщающем компрессор 9 с цилиндром 10 дизел , размещен инжектор 11. Компрессор 9 установлен на одном валу 12 с турбиной 13, котора сообщена с цилиндром 10 через выпускной трубопровод 14. 10 and the glow plug 8. In the inlet pipe 3, connecting the compressor 9 to the diesel cylinder 10, an injector 11 is located. The compressor 9 is mounted on the same shaft 12 with the turbine 13, which communicates with the cylinder 10 through the exhaust pipe 14.
15 В цилиндре 10 дизел установлены свеча зажигани 15 и форсунка 16.15 A spark plug 15 and nozzle 16 are installed in the cylinder 10 of the diesel engine.
Запуск дизел осуществл етс следующим образом.The start of the diesel is carried out as follows.
Воздух, бжатый в нагнетателе 5, приво-. димом от электромотора 6, подают в камеру 1. Через дополнительную форсунку 7 в камеру подают и распыливают дизельное топливо.The air bzhaty in the supercharger 5, led. dim from the motor 6, is fed into the chamber 1. Through an additional nozzle 7 into the chamber serves and sprayed diesel fuel.
