Изобретение относитс к диагностированию дизельных двигателей, в частности, к измерительной технике.The invention relates to the diagnosis of diesel engines, in particular, to measuring equipment.
По основному авт. св. № 52148О из-вестен способ определени мощности дизельных двигателей l , основанный на идентичности характера изменени расхода топлива в функции мощности.According to the main author. St. No. 52148O, a method for determining the power of diesel engines l is known, based on the identity of the nature of the change in fuel consumption as a function of power.
Максимальную мощность двигател определ ют по формуле: -JQ N ./ GTN-OTX у/ /-,)The maximum engine power is determined by the formula: -JQ N ./ GTN-OTX at / / -,)
где G - расход топлива, соответствую-where G is the fuel consumption corresponding to
щий максимальной мощности; G - расход топлива при работе is max power; G - fuel consumption at work is
двигател вхолостую; V и d - посто нные коэффициенты, завис щие от конструктнвньос особенностей двигател . Данный способ примен етс при испыта-20 НИИ дизелей со свободным впуском. Дл дизелей с газотурбинным наддувом этот способ неприемлем из-за чрезмерных пснгрешностей определени мощности, обусловленных зависимостью коэффициентов V и о от давлени наддува.engine idle; V and d are constant coefficients depending on engine design features. This method is applied at test-20 Research Institute of Diesel Engines with a Free Intake. This method is unacceptable for gas turbine supercharged diesel engines due to excessive determinations of power determination due to the dependence of the coefficients V and 0 on the supercharging pressure.
Цель изобретени - повьпиение точности способа.The purpose of the invention is to demonstrate the accuracy of the method.
Указанна цель достигаетс тем, что в способе измер ют давление наддува при работе дизел вхолостую при номинальной частоте вращени , а значение мощности корректируют умножением на коэффициентThis goal is achieved by the method of measuring the charge pressure during idle operation of a diesel engine at the rated speed, and the power value is adjusted by multiplying by

где а, Of}, b/i bi- заданные коэффициенты , которые выбирают из пределов 3 - 3,5; 1,5 - 2,1; 1 - 1,2 и 1,1 - 1,2, соответственно в зависимости от типа двигател ;where a, Of}, b / i are bi-specified coefficients, which are selected from the limits of 3 - 3.5; 1.5 - 2.1; 1 - 1.2 and 1.1 - 1.2, respectively, depending on the type of engine;
Рцр- давление наддува при работе данного типа двигател под нагрузкой;Рцр- boost pressure during operation of this type of engine under load;
рцу- давление наддува при работе дизел вхолостую на номинальной частоте вращени ;Rtsu - boost pressure when the engine idles at the nominal rotational speed;
номинальный расход топлива ; nominal fuel consumption;
Q - расход топлива в момент измерени .Q is the fuel consumption at the time of measurement.
