2 stroke emergency stops???

GM also produced a 51 series (valveless)
2 cyl & 4 cyl (now very collectable)

not forget n the series represents the cubic capacity of each cyl .....51cubic inches ,53,71,92,149

But

OK
Sum Jimmyless Crummins owner Iz Q:? the 51 series

Detroit Diesel Engines

Detroit diesel produced the first supercharged two cycle diesel. The series 51 was the "TRUE" 2 Stroke; G.M. needed a new engine to take the 51's place...

The series 53 was the engine that took the 51's place. The 53's were G.M.'s first diesel with valves, inline and V configuration were available (inline: 2, 3, 4) (6V, 8V). The 8V53's had a timing gear train problem. The gear train was to light for the valve train load, this was common for some 6V53's. G.M needed a bigger engine with more power.

The series 71 fixed the 53's timing gear problem and let Detroit make bigger engines with more power and torque. Series 71 came in many configurations (inline: 1, 2, 3, 4, 6) (6V, 8V, 12V, 16V, 24V)...

Series 92 was the new replacement truck engine, 71's were squeezed to the limit. The 92's were cheeper to run and more reliable. Came in 6, 8, 12, 16,24V configuration

Series 149's were made after W.W II for mining and other heavy uses in construction and marine. Came in 8, 12, 16,20V configuration


Detroit Diesel Series 51

The Detroit Diesel Series 51 was a two-stroke diesel engine. Two versions were produced, an inline two-cylinder and an inline four-cylinder model. It was a simplified version of the Series 53 that did not have exhaust valves. This was accomplished by using scavenger ports for both intake and exhaust, similar to a two-cycle gasoline engine. Since the Diesel fuel is injected just before top dead center virtually no unburnt fuel is expelled in the exhaust unlike a two-cycle gasoline engine. The elimination of exhaust valves reduced the complexity and weight of the engine. This allowed the engine to be more portable and easier to service. Its uses include: Marine propulsion, generators, pumps and other industrial uses. It was never used for automotive purposes.

wasnt there a 110 series or am I just dreaming ?

Not bad info there Swishman..

Without interupting the thread too badly..
Do you have some operation schematic diagrams?
Particularly, the blower flap configuration..

thank you

wasnt there a 110 series or am I just dreaming ?

Yeah mate it was the 6-110 mainly for industrial specs I believe

hmm,
no, but I'll take your word for it.
More research (by me) needed.
Sounds like one of those cockamamie british ideas.
2 stroke not 2 cycle, ports, turbo's and valves. ???
Why don't we just perfect the blowing up part?
(and give them something entertaining to do until their all gone?)
LOL

:-X

maybe this might help Bobsboy

Thank you mrsmackpaul.

I think I got it now.

I am intrigued and facinated again.

It's not just one of those funky, obsolete loopy pommy engineering concepts.
(Now the Knocker Lads will be after my blood.)

A combined exhaust/ intake/ compression stroke,
The exhaust valve and injector working in PRECISELY TIMED UNISON)

The blower blasts air through the exposed inlet port and the open cylender (exhaust valve open),

The piston blocks the port, the exhaust valve closes, the piston continues its up ward journey, the remaining air in the cylender is compressed, the injector shoots its mixture, and hey presto magic, the whole thing explodes, the piston is sent to the bottom of the cylender in a mighty, hurculean burst of Detroit Power ! !
where the whole process begins anew.

Brilliant,
I wants one again.
LOL

P.S.
Through out this thread, I was always wondering how long it would take Mr Swishy to bite.
: :-X

idstbc olddon (the only thing wrong?)
ta

The only thing wrong there,is that it is a blower,not a turbo.

Az eye've sed
There B 2 types of ppl in thiz world
Thaose th@ have screeemers
n Those, they wish they did



OlDon
a late invention for the 2 stroke screeemers twaz to have a blower & a turbo

yes not forget n the 110 series straight 6...the Victorian Railways had many

n 4 those th@ like/can reed ....bit more info...jist clik on theze 2

And Swish, is it true that most of these engines are preserved on the bottom of various waterways, anchoring Cray Pots, Bouys and other Marine Stuctures?
