My grandfather had a small trucking company in Puerto Rico. He had several Brockway’s equipped Detroit diesels. His girl was a 1972 Sporting a 12v71. I remember going over the mountain and listening to that Detroit scream. It always brought a smile to my grandfathers face. I can still remember it like it was yesterday. You don’t hear them very often today.
145 hp/cylinder, @2100 revolutions... Horse to the inch! potted heads, she was meant to perform... and did! Hudson, you're so right... Silos couldn't keep these engines quiet....
Cool engine. The came in two blocks, a V6 block and a V8 block. They never build a V6 149 though. The V8 block was used for the 8V, the 16V, and the 20V engines, and the V6 blocks were used in the 12V and 20V engines. A 20 cylinder 20V149 had a V6 block at one end, a V8 block bolted to it in the middle, and another V6 block bolted to the other end of the V8 block. The 12V149 had two V6 blocks, the 16V149 had two V8 blocks. 6+8+6=20 cylinders. Multiply that by the max HP rating of 125 HP per cylinder. The heads, cams, injectors, blowers, etc were piled on according to how many cylinders it had.
Ignignokt M..... any "hunting" or "wandering" on these, is ALWAYS corrected at the buffer screw in the governor... on the early "mechanical" engines, not on the DDEC engines.
I hade some thing strange happen on a boat i worked on with 16v149 2 stroke bowthrustesr DP. One night while checking the oil, they burn some, i saw a small while ball of light shoot from the the manifold to the angle steel frame that supported the deck plate1 What caused it/ Are there plasmoid formed in this 2 stroke due to the angle shape of the intake ports?? It mwas like a white spark that jumped about 4 inches since the engie sat low in the bow thruster room!
Demolition dave drilling n blasting-- looked like temp gage read bout 160. Thats bout as warm as DETROIT RUNS. THE COOLEST RUNNING OF DIESELS. Its cooled 3 ways. Its cooled by air from blower, coolant from rad. and oil cooled from oil being injected up under pistoninside piston skirts towards top end rod bearings!!!!!!! That why you see shutters on the rads, they run so cool you need shutters to build heat. Names HIPIE
These engines do their best work at ~1,800 RPM. A 16 cylinder 2 stroke Detroit diesel sounds like a 4-cycle V-8 turning 7,200 RPM! It sounds like it's screaming, but, this is its normal operating range. If you red line it, (2,200 RPM) it will sound like 8,800 RPM. They even knick-named trucks that use 2-stroke V-8 Diesels, "Screaming Jimmies".
@@vincentrobinette1507 back in the 1970s/80s Road Trains in Australia's Northern Territory, we called the 8v71/8v92Turbos "bird scarers", truckies would see flocks of birds taking off a mile ahead of them.
Charles Kettering invented these engines. Also Zephyer train and AC freon AC Delco electric start and lights for Cadillac. Was an American Jewish genius. Shalom
yes. The 149 had individual cylinder heads that fit into a recess in the block. The camshafts were in the block too, but because the heads were recessed into the block, the cams were also overhead cams. 4 exhaust valves per cylinder head, and blowers ( that were also recessed into the block ) forced air into the intake ports in the cylinder that were uncovered near the bottom of the stroke. I remember overhauling a 12V149, you assembled the piston onto the conrod, then inserted the piston into the cylinder liner, then inserted the whole cylinder liner-piston-conrod assembly into the block. The liner-piston-conrod assembly weighed something like 80 pounds.
Depends on the application, pretty sure most diesels this size and be run on HFO but I've not specifically checked on this one. I'd guess for this video it's just burning diesel though.
@@Romans--bo7br I just use shell rottell sae 40w oil with a touch of XD-100 to boost film strength. I also run the sae 40w in my yz-250 motor at 40:1! It works good in both diesel and gas 2 stroke and it's cheap!
That sure is an SLB blue lookin' engine. That'll be the biggest thing I miss about the oilfield - CATs are a dime a dozen, I MISS how those old 2 strokes sound on location, despite that they can't pump pressure worth a damn.
