Description
(54) СПОСОБ ИСПЫТАНИЯ ДВИГАТЕЛЯ ВНУТРЕННЕГО СГОРАНИЯ С КЛАПАННЫМ ГАЗОРАСПРЕДЕЛЕНИЕМ В СТЕНДОВЫХ УСЛОВИЯХ Изобретение относитс к области машиностроени , в частности к двигателе строению, и может быть использовано при испытани хдвигателей в стендовых услови х. Известны способы испытани двигател внутреннего сгорани с клапанным газораспределением в стендовых услови заключающиес в том, что контролируют характеристики двигател при его работе на заданных скоростном и нагрузочном режимах и воздухоснабжении от постороннего источника сжатого воздуха 13 Однако при реализации известных способов значительно снижаетс давление в модельных услови х по сравнению с давлением в холодных услови х, так как при увеличении объема камеры сгорани давление сжати уменьшаетс более резко , чем температура. Кроме этого, изменение объема камер сгорани приводит к изменению зависимости текущей температуры рабочего тепа в шшиндре от угла поворота коленчатого вала по сравнению с зависимостью в холодных услови х. Также имеет место изменение условий воспламенени и выгорани топлива относительно условий при холодном пуске вследствие того, что увеличение объема камеры сгорани измен ет относительное положение струй тсплива и поверхности поршн И| следовательно, распределение топлива в камере сгорани , и изменение циклового расхода воздуха, поскольку параметры воздуха в цилиндре в момент закрыти впускных органов не соответствуют таковым при холодных услови х. Таким обрезом, {реализаци взвестньос способов либо сопр жена со значительными материальнььш затратами, либо не позвол ет моделировать конкретные холодные услови на BnydSe двигател , поскольку текущие параметры рабочего тела в цилиндре и суммарный коэффициент иэбытка воздуха вл ютс произвольными величинами.(54) TEST METHOD FOR INTERNAL COMBUSTION MOTOR WITH VALVE GAS DISTRIBUTION IN STAND CONDITIONS The invention relates to the field of mechanical engineering, in particular, to an engine structure, and can be used for testing engine in stand conditions. Methods are known for testing an internal combustion engine with valve timing in bench conditions, namely, controlling engine performance when it is operating at given speed and load conditions and air supply from an external source of compressed air 13 However, when implementing known methods, the pressure in model conditions for compared with pressure in cold conditions, since with an increase in the volume of the combustion chamber the pressure is reduced more sharply than the temperature Hooray. In addition, a change in the volume of the combustion chambers leads to a change in the dependence of the current temperature of the working heat in the shsinder on the angle of rotation of the crankshaft as compared to that in cold conditions. There is also a change in the ignition and fuel burnout conditions relative to the cold start conditions, due to the fact that an increase in the volume of the combustion chamber changes the relative position of the spray jets and the piston surface And | therefore, the distribution of fuel in the combustion chamber, and the change in the cycle air flow rate, since the air parameters in the cylinder at the time of closing the inlet bodies do not correspond to those under cold conditions. This cut-off, {the implementation of most advanced methods either involves significant material costs or does not allow simulating specific cold conditions on the BnydSe engine, since the current parameters of the working fluid in the cylinder and the total air intake ratio are arbitrary values.
