Изобретение относитс к испытанию автотракторных двигателей и может быть использовано при диагностировании системы питани дизел .The invention relates to the testing of automotive engines and can be used in diagnosing a diesel power system.
Известен способ определени расхода топлива через форсунку работающего дизел 5 путем организации измерени расхода на линии нагнетани топливного насоса высокого давлени (ТНВД). Дл этого контролируют форсунку снимают с двигател и соедин ют с ТНВД вспомогательным трубопроводом, при этом во врем работы дизел происходит впрыск в мерную емкость 1.A known method for determining the fuel consumption through a nozzle of a working diesel 5 by organizing flow measurement on the injection line of a high pressure fuel pump (high pressure pump). For this, the injector is monitored from the engine and connected to the injection pump by an auxiliary pipeline, while during operation of the diesel, injection into the measuring tank 1 takes place.
Недостатком способа вл етс высока трудоемкость монтажно-демонтажных работ.The disadvantage of this method is the high complexity of installation and dismantling.
Кроме того, способ характеризуетс не- 15 достаточной точностью вследствие того, что впрыск производитс в среду без противодавлени (в цилиндре дизел противодавление воздуха в момент впрыска достигает 40-60 кг/см), а подача топлива к форсун- jo ке производитс нерабочим вспомогательным трубопроводом, измен ющим характеристики впрыска.In addition, the method is characterized by insufficient accuracy due to the fact that injection is carried out into the medium without counterpressure (in the cylinder of a diesel engine, the counterpressure of air at the moment of injection reaches 40-60 kg / cm), and the fuel supply to the injector is produced by an off-line auxiliary pipeline modifying the injection characteristics.
Цель изобретени - сокращение трудоемкости и повышение точности.The purpose of the invention is to reduce the labor intensity and increase accuracy.
Указанна цель достигаетс тем, что измерение количества топлива производ т на всасывающей магистрали, отключают всасывающую магистраль от питающей полости насоса, производ т впрыск топлива только через контролируемую форсунку путем периодического в соответствии с фазами работы неконтролируемых форсунок понижени давлени топлива в полости питани насоса и дальнейшего восстановлени этого давлени На врем действи контролируемой форсунки, по достижении заданного количества циклов сообщают полость питани насоса с всасывающей магистралью и по количеству топлива, поступившего в насос за промежуток времени между началом сообщени полости питани насоса с всасывающей магистралью и моментом выравнивани давлений во всасывающей магистрали и полости насоса, суд т о расходе топлива через форсунку.This goal is achieved by measuring the amount of fuel on the suction line, disconnecting the suction line from the pump feeding cavity, and fuel is injected only through a controlled nozzle by periodically according to the phases of the uncontrolled pressure nozzles in the fuel supply cavity and further restoring of this pressure At the time of the action of the controlled nozzle, after reaching a predetermined number of cycles, the supply cavity of the pump is reported to th line and the quantity of fuel released to the pump by the time interval between the beginning of the message of the pump power with a suction line and a pressure equalizing point in the suction pipe and the pump cavity, judged on the flow of fuel through the nozzle.
На чертеже представлена блок-схема устройства , реализующего способ.The drawing shows the block diagram of the device that implements the method.
Предлагаемый способ может быть реализован с помощью устройства, состо щего из измерител 1 количества топлива, клапана 2, гидроцилиндра 3 и блока 4 управлени .The proposed method can be implemented using a device consisting of a fuel quantity meter 1, a valve 2, a hydraulic cylinder 3, and a control unit 4.
