It might be the case for most stationary applications, but what I have seen is resorting to CNG to replace part of the charge air, thus leading to a richer AFR which decreases the likelihood of knock. Then, even though the Diesel system won't be really idling, as it may have the same amount of injection cycles, the Diesel fuel flow is decreased accordingly to get the AFR closer to the usual.
