No doubt you’re familiar with the function of the governor on your engines. ⠀ ⠀
And you might also be aware of what can happen when a governor has been incorrectly set up – we were certainly reminded of it the other day.⠀ ⠀
We had a Deutz BF6M1013 engine on test after a rebuild, where it was producing 230hp, instead of the required 279hp. ⠀ ⠀
The engine had been built from a donor unit after the original engine suffered a broken crankshaft along with the damage accompanying this type of failure!⠀ ⠀
The governor was a special Heinzman unit for this type of engine, similar to the one below. These units are interchangeable but have to be reset if used on a different block, or the control rod is changed.⠀ ⠀
Having contacted Deutz and Heinzman, we were told they don’t have anyone who can set this particular unit, so we tracked down an independent specialist.⠀ ⠀
Even with our vast governor knowledge and own governor test rigs, we are not set up for this type and were reliant on someone else.⠀ ⠀
Unfortunately, having refitted the governor after it had been set, the engine’s output was even less!⠀ ⠀
The resolution was to get the specialist to come and set the governor whilst the engine was on test, as with as little adjustment as 0.2mm affecting the output by 50hp, he could not get a true simulation on the test rig.⠀ ⠀
As with all engines, a fine adjustment can make a big difference!⠀ ⠀

Last month we attended a local boatyard in order to change the sump gaskets on two MTU 10V 2000 M72 engines.⠀ ⠀
After each engine was drained the sumps were lowered to the ground and cleaned to remove the used oil, and the faces of both the sump and blocks were cleaned to ensure the new gaskets sealed correctly.⠀ ⠀
This work scope went as expected with no problems, but the value of our engineers being onboard, meant the operator was made aware of other issues which had been missed: ⠀
⠀
Leaks around alternator shaft seal - This leakage will only increase with further engine⠀
Leaking around damper bolts - The bolts around the edge of the vibration damper also had streaks of oil indicating that oil was leaking past the bolts - The damper was cleaned to enable any leakage to be monitored.⠀
Exhaust leak from the intermediate plate between the exhaust manifold and the cylinder head⠀
Leak at the rocker covers shown to us by the crew⠀ ⠀
Our engineer’s recommendation was that the alternator shaft seals, rocker cover gaskets and the exhaust leak should be prioritised as they will only deteriorate over time.⠀ ⠀
With this information, the client rebooked for this work to be carried out whilst the vessel was in the dock the following week.⠀ ⠀
It’s always valuable to carryout regular engine visual inspections, either by your own crew, or anyone else who is working on the engine.⠀ ⠀
If you’d like to arrange an inspection or have any concerns, please get in touch, we’d be happy to assist.

We had a request for technical support onboard a m

We had a request for technical support onboard a major shipping company’s vessel this week.⠀
⠀
The Fleet Superintendent got in touch with us to report that one of their MAK 8M20 engines started experiencing high exhaust temperatures and producing black exhaust smoke.⠀
⠀
As well as logging temperatures and pressures, they had already completed some of their own investigations, including:⠀
⠀
• Check Scavenge Air Cooler – Found to be very dirty. The client has cleaned this but this made no difference, however, it may not be completely clean⠀
⠀
• Valve timing checked – Inlet valve opening duration was 12 degrees different to the other engine⠀
⠀
It’s always difficult to diagnose this type of issue without being on-site, but to support the client one of our engineers provided the following information and asked some specific questions to help get the engine operating properly:⠀
⠀
“Black smoke is caused by⠀
⠀
Lack of air in the combustion chamber⠀
Too much load on the engine⠀
Too much fuel being injected⠀
Incorrect injection timing⠀
Incorrect valve timing⠀
Faulty injectors⠀
Dirty fuel⠀
High exhaust temperatures are caused by⠀
⠀
Excessive back pressure in exhaust (blockage in pipe or silencer)⠀
Too much load on engine⠀
Lack of air in combustion chamber⠀
Lack of ventilation in engine room⠀
High engine inlet air temperature (intercooler/aftercooler)⠀
⠀
As you can see, black smoke and high exhaust temperatures can be caused by the same issues.⠀
⠀
I can see that the inlet valves are open for 12° less on this engine than Engine 1. Obviously, this would mean less air in the combustion chamber, but I do not know if it would be enough to cause your issues.⠀
⠀
I would be more concerned that it is different at all. Valve timing is normally set deep in the engine and does not change during normal engine running.⠀
⠀
Have these symptoms appeared suddenly, or has it been a gradual increase in temperature? A sudden increase would indicate something breaking whereas a gradual increase might indicate the engine wearing or accumulating carbon deposits.⠀
⠀

During a recent job, we realised that the cylinder

During a recent job, we realised that the cylinders on the engine had been misidentified.
It reminded me of a much more serious problem we’ve seen before, which you can see in the picture below.
All this was as a result of the A-bank pistons being fitted in the B-bank and vice versa.
Not only is it critical to return the pistons to the correct bank of the engine, but when it comes to communicating, resolving and recording engine information, it is just as important to correctly identify the cylinder, as not all manufacturers use the same system.
Different engines can be labelled as ‘Left’ and ‘Right’ or ‘A’ and ‘B’ with cylinders numbered from the drive end or the free end.
MTU us the ISO1204 system for numbering cylinders, where Paxman use the opposite.
Waukesha use a mix of the two and Caterpillar only use numbers and no letters. Mitsubishi also use only numbers but in a completely different way to Caterpillar!
The manual should tell you which system is used, but if you don’t have this information, we will have.

Correct storage is vital for your critical engine

Correct storage is vital for your critical engine spares...

We’ve recently received two sets of critical CAT

We’ve recently received two sets of critical CAT 3408 engine spares from an operator.

Their previous service company advised them that they were either unsalvageable or out of spec & would require repairing – at an eye-watering high cost.

Before taking this costly step, the operator decided to send the parts to us to inspect for a second opinion.

The parts arrived at Bartech completely stripped & on multiple pallets. A lot of the parts were in poor condition and covered in rust. One of the boxes was labelled as scrap!

On first glance, we would be inclined to agree that many parts were unsalvageable, but as we started the full thorough inspection of each component we found a lot of evidence to the contrary.

Our findings include:
• Cylinder liner bores repairable, either by boring and sleeving or by using Belzona • Corrosion on the top deck doesn’t seem to be enough to cause an issue – there is light corrosion on the deck faces where the water transfer ferrules are seated, we have the option to bore out & fit inserts • One camshaft that was pitted cleaned up with light polishing & can be reused pending full polish & MPI crack detection
Even with our engineers carrying out the rectification works required & sourcing the parts that do need replacing the operator has saved a huge amount bringing them to us.

If you have any issues with your current maintenance provider or have been given bad news with a high price tag, feel free to get in touch to see how we can help.

As part of an inspection and filter replacement wo

As part of an inspection and filter replacement work scope recently completed on two MTU 20V 4000 engines, we noted something that can impact the performance of your engine.⠀ ⠀
We were on-site to replace the airflow restriction indicators, along with the Separ filters, and when changing out the filters we made the discovery shown in the attached picture. ⠀ ⠀
The engine has two fuel filters which were both removed and it was found that the left-hand filter was dry inside, indicating it had not been used in tandem with the filter on the right.⠀ ⠀
The system is designed so both filters are used simultaneously whilst the engine is running.⠀ ⠀
There is a lever to isolate one filter if it needs to be changed whilst the engine is running, but then it should be moved back into the central position after the changeout.⠀ ⠀
On changing the filters, our engineer returned the lever to the correct central position.⠀ ⠀
If you are experiencing limited fuel flow, it is worth checking the filter arrangement before anything else.⠀ ⠀
If you have any concerns with the performance of your engine, get in touch, we’d be happy to help.

Last week we got a call from an operator facing so

Last week we got a call from an operator facing some major downtime issues, the situation provided a good example of how well-managed strategies can prevent these emergencies.⠀
⠀
The engine drives a safety-critical pump, and when a fuel pipe failed, they were looking at shutting down the site.⠀
⠀
I’m sure you have reviewed critical spares holdings and from my experience, there are usually plenty of discussions between technical, operational and financial departments!!⠀
⠀
Whilst this will normally include gaskets sets, some injectors, filters with possible additions of sensors, a couple of cylinder heads and maybe a turbo, it doesn’t always include pipes.⠀
⠀
For the operator above, we were able to manufacture, test and despatch replacement fuel pipes within 6 hours of the call, but the reality is that might not always be possible.⠀
⠀
For such a critical component it should definitely be considered as part of your contingency spares strategy.⠀
⠀
P.S. Here are some kind words from the client: “As always Rob, amazing result. Thank you so much!⠀
⠀
If you would like any help in reviewing your spares holding strategy or have any fuel pipe requirements, we’d be happy to help. Contact us now.⠀
⠀
** Due to the short time taken to get the pipe despatched, I don’t have a photo,⠀
but this is an example of pipes we have made previously.

An amazing video we wanted to share from Marine Insight.
