Abstract

Выбросы, выводимые из двигателя, такого как дизельный генератор, можно определить из нагрузки на двигатель и объема выхлопных газов из двигателя. Химические вещества, такие как оксид азота (NO), можно вычислить для измеренной нагрузки на двигатель. Вычисление может включать в себя определение расхода воздуха в двигателе из измерений давления воздуха и измерений скорости вращения турбины турбокомпрессора. Вычисление может также включать в себя определение расхода газа в двигателе путем получения расхода топлива из известных результатов испытания. Расчетные выбросы на выходе можно использовать для обеспечения соответствия двигателя природоохранному законодательству. Программа дистанционного контроля может вырабатывать аварийные сигналы, когда двигатель не удовлетворяет природоохранному законодательству.
