Greetings Forum
Our site has a set of diesel gensets (about 1 MW each). They sat for a while (6 months) without maintenance due to some ownership transfer issues but when our maintenance guys tried to crank them back up, they would not. Soon after they found urea had crystallized in the portions of the exhaust sytem and blocked the air flow. Also, urea and fuel were leaking out of the pistons. It appears as though a solenoid valve failed and the urea injection system leaked urea into the system.

Is solenoid valve failure common in these types of systems? Typically should the urea injection control system indicate when there is a failure? What should be done to try to avoid failure in the urea injection system again? I appreciate your assistance.
Thanks

The variants of generators are segregated as per fuel efficiency, size and types. There are separate models available for specific usage and wattage requirement.Industrial diesel generators have longer life span than other fuel types. The acquisition cost is low and these generators are also low maintenance.
