“1980 found the Detroit Diesel Allison division trailing Cummins in the market it had created. Though Detroit Diesel hung on to a 30 percent market share, its sales continued to drop, and by 1987, its share had dwindled to less than 5 percent.”
As I also stated.
“Detroit’s electronically controlled Series 60 diesel engine was introduced during the first quarter of 1987. What was unique about this mill was that it was the brand’s first ever clean-sheet design.”
While some say the whole bleedin motor’s design was just bought in from JD lock stock and barrel depending on who you listen to and believe.
But certainly at least much of what mattered.
So on the drawing board, in large part outside the Detroit Diesel operation and well before the end of the two stroke was even envisaged.
Then introduced just as GMC trucks division and Detroit Diesel engines division was offloaded to Volvo and Penske respectively.Not exactly a ringing endorsement for GMC’s 4 stroke credentials or preference.
You won’t find many 60 series in many Astros.
Although MTU certainly knew a good thing when they saw it given the choice of the redundant 2 stroke operation for customers who wanted and could still put something better than a 4 stroke 60 series in their boats.
Not surprising when at best it eventually took 16 litres of turbocharged 60 series to make around the same power as a 16v71 N Detroit and not much more than a 12v71 N.With all the added aggravation of the cam in head valve train.
Also bearing in mind there was actually an electronic controlled development of the two stroke.
Given a bit of development the two stroke possibly could have been turned into an electronic controlled, 13 litre, inline 6, with some serious forced induction technology, producing around 550 hp peak power at around 1,000 rpm.
Exactly what do you think that Volvo is suggesting and referring to regarding an EV outfit that will work for longer distance use in ‘Europe’ .Just chuck a few batteries under a tractor unit it’s that simple, right.
Citation please.
You hear, or remember snippets of information and weave a bs story around it, in other words you haven’t got a clue.
Volvo came to a supply agreement concerning their marinised motors, nothing unusual about that, Volvo had supply agreements with many engine manufacturers.
Apart from ships, where else are two stroke fitted?
Not in any automotive applications, not in motrcycles, not in lawn mowers or other gardening application and not in any industrial applications, large or small. I wonder why that is.
Your 2T garden tools are most likely petrol, and most likely use 2T oil and the crankcase is used to transfer the charge (under pressure) into the cylinder.
The 2T diesels we’ve been looking at have oil in the crankcase, to give a long service life in trucks, trains, ships; they do not use the crankcase to transfer the air into the cylinder.
Motorcycles etc, mostly use the same system as lawnmowers etc.
No real moderators will actually say if it is the case for an individual, but if someone is put on “pre-mod” for being naughty then all of their posts are vetted before being put up on the site.
If you look, some posters are quiet for a long while, then a dozen posts appear within a few minutes…draw your own conclusions.
Get it right I said GMC trucks division was offloaded to Volvo.GM Detroit Diesel 4 stroke division was offloaded to Penske, two stroke went to MTU.
What has any of that that got to do with Volvo’s clear intent to push for European wide long distance EV truck operations, obviously and predictably and logically based on Scandinavian type drawbar outfits.In which a rigid prime mover bearing no trailer weight offers more scope for battery carrying capacity.
Which fits the definition of couple it up we already know the overall length and gross train weight, then change the bleedin rules in any EU affiliated state where they don’t fit.Including here.Job done.EV trucks that actually work in the real world of European haulage.Obviously NZ too.With the difference that Australia can put two trailers on the rig if they ask the government nicely.It’s all about saving the planet right.
This topic reminds me of this old film.Can’t think why.( Watch the ending ).
