| Diesel engines
Hi,
Most diesel engines have a watchkeeping panel, especially with regards to Lub. oil to prevent a catastophic failure.
Carbon build up is common in manifolds during low load running, due to gas byepass from the pistons,as they are not at their correct operating temp. due to expansion.Low load running can be seen normally by exhaust gases from the funnel/exhaust system being of an oily nature.
The Royal Navy have normally 4 generators onboard, 2 online....split switchboard( for normal/alternative power supplys)which we need during a war situation.Often was the case that these gen sets would operate underloaded, so we used to try and switch on as much equipment as possible, reducing exhaust scatter temperatures.
In harbour I would regularly get a load barge alongside,and load up the diesels..to 110% overload,checking governer stability,response and droop.
This would clear all carbon deposits and reduce exhaust temps. dramaticlly.
