Sir, I have a question. As I know about Urea, It is 40% of CO(NH2)2 in water solution, so it needs to be decomposed first. Then in decomposing process, Is there any side effects such as generation of CO or CO2?

[@tanboonpin5840]

Hi good day, The last part where you said pressure for scavenger gas receiver decrease resulting in higher temp in exhaust gas after combustion. Can you explain how it is like that? i thought higher pressure = higher temperature.

How is the amount of urea dosing decided?

[@marineengine-2strokeinspec544]

Well.. Dosing amount can be confirmed by bucket test.
And As far as I know.. dosing amount is decided by automatic calculation by system base on the settings during the FAT.

what is the function of EGB ??

[@marineengine-2strokeinspec544]

EGB Exhaust Gas Bypass! You have to reduce the power to Turbocharger by means of bypassing Exhaust gas depends on how you turning the engine such as part load tuning. If your engine is part load tuning then it will exceed the maximum pressure at 100% load if you don't bypass the exhaust gas to Turbocharger.
