Sulzer (company that designed that engine) have a good reputation.
One chemical plant I worked at for a while installed a 3 cylinder Sulzer air compressor to increase their compressed air capacity during one of the plant upgrades. The compressor was good, but presented a lot of challenges to prevent the pipework from cracking due to some complex vibrations - Sulzer came up with some interesting additions to the discharge area, but they weren't completely successful.
I can't recall the displacement of the Sulzer compressor but it is 2 stories high. The main compressor has much greater capacity, but it is an axial compressor driven by a large steam turbine.
A turbo charged and intercooled, direct injection diesel for automotive use will usually have a BSFC figure less than 0.35 lbs/hp/hr at maximum power.Quote:
Fuel consumption at maximum power is 0.278 lbs per hp per hour (Brake Specific Fuel Consumption). ...
For comparison, most automotive and small aircraft engines have BSFC figures in the 0.40-0.60 lbs/hp/hr range ...

A medeum size sulzer.
This is not one of my pics. scammed off the net.
Working around the wharves i have been lucky to see a few ships engines
being repaired or having a head change truly interesting.
imagine the size of the tension wrench..Mark

For those that haven't/can't see the pics I believe this is the engine referred to

i just love how engines work,, and to see how sumthing that massive and all that wight been thrown about it still amazes me
They use a device that screws onto the thread protruding through the nut, then use hydraulics to stretch the stud. The nut can then be tightened/loosened by hand.Quote:

Bet that's not a 1624;)Quote:

Thread puller,dangerous mongrol of things.Around sites now they have been replaced with hydro nuts,they are a hydraulic jack with a threaded section that screws down and holds the tension.Hytorcs are still in abundance and they are also a good machine to use. Pat
