Dear Gentlemen,
Where could I get more information about the thermal oil boiler?
Anyone with experience working with thermal oil boiler, would appreciate yr kind & valuable input, thank you.

Dear Sir, Very well written. Your advice is highly regarded. Actually we are using MGO & HFO 180cst. for changeover. Further to that, could you pls clarify for the following;- 1. if we advance the timing too much, would it cause heavy knocking? 2. if the barrel & plunger is worn, the fuel ra...

Dear Sirs, These are my queries:- 1. Is it correct and advisable to advance the fuel pump timing for a diesel engine if the fuel pump barrel & plunger is worn out ? 2. What is the maximum deviation or allowable range of degrees BTDC compared to the original fuel pump timing setting ? Your advice...

Dear Gents, First & foremost, Dieselduck is very sharp, the HND is in fact HENAN diesel engine, the so-called Chinese Deutz (by JK). All the cylinder heads were found in good order. Have not check the pistons & lubrication yet. The speed controller is found in good condition. The fuel pump h...

The consequences of engine overspeeding

Dear Gents,
Here are some more pictures for yr perusal.

Dear Gents, 1.We found 2 pcs of broken bolts from the crankweb counter weights inside one of the cylinder units. I was wondering whether these broken parts caused overspeed or after overspeed , these bolts were then broken off.? Consequently, we had a sidekick causing damages to the cylinder block. ...

To provide you here with more details:- 1. This overspeed happens to our high speed diesel genset. The genset had been running for the last 24 hours without any abnormal parameter. 2. It happens all of a sudden and causing severe damages to the engine block, conn rod, crankshaft, bearings, etc. 3. T...

What are the causes for diesel combustion engine suddenly running overspeed ?

What is the allowable range for Vanadium content in bunkered fuel so that it won't cause problems for medium speed diesel engine?
Do you think that 183 mg/kg out of 200 mg/kg (ISO specs IP501 std max) is too high for a 180cst fuel ?

Very good advice by BP. However I am curious to know whether there is an allowance or margin to advance or retard , let say 1 or 2 degs deviation from the maker's shop test records. And would this affect and result in high exhaust temperatures and fuel consumption ?

If the valve stem seals are defective, will this contribute to the suction / inlet valve cut / damage ?

Would like some advice on how to attach some pictures here so that I could provide more details for sharing about technical problems.
Thank you in advance.

Will this cause the exhaust valves to cut / leaking while in operation ?
Would appreciate valuable explanation.

Dear Sirs,
What are the causes for inlet / suction valves cut during operation for a medium speed diesel engine ?
Appreciate yr valuable feedback. Thks.
