Talk:Diesel–electric powertrain

message: It would be nice if the "Ships" section quantified what it means by "recent development". There have been diesel-electric/prop ships in the US since at least the 1950s (Puget Sound ferries), and diesel-electric/paddles in the UK since 1934(search for ferry). That doesn't seem all that much more 'recent' than the dates being compared, 1912 and 1920s. (Of course, there's also the problem that ship doesn't mention "diesel-electric" at all.)

message: The training msword document was provided to meet a request for a citation for the statement about a mechanical transmission being more efficient than the diesel electric.  The document discusses the reasons electric is used instead of mechanical, etc.--68.35.158.218 (talk) 09:05, 18 July 2008 (UTC)

message: I've moved the page to Diesel-electric transmission, as well as creating a redirect from Diesel-electric powertrain for those who use that term.  It's a much better and more correct title - "diesel-electric" is just an adjective.FengRail (talk) 19:59, 8 April 2009 (UTC)

*Lists of vehicles need some text to go with them
*There is an article hybrid vehicle - that some info may be moved to.
*inline references
I will attempt some of this, but am not volunteering to do all.FengRail (talk) 20:13, 8 April 2009 (UTC)

message: Why can't an internal combustion engine provide full torque at 0 RPM of the engine-output shaft? 
Once the fuel-air mixture is ignited in any cylinder, it should exert a force  on the corresponding piston (higher pressure of compressed combusted air, across the area of the piston head) - irrespective of whether the piston yields to this force and moves. The sustenance of this force then depends on the gas pressure inside each chamber. The latter is a function of two things:
1) How long the burnt fuel-air mixture stays hot - thereby maintaining the positive pressure on the piston
2) The timing/sequence of opening and closing of the exhaust and fuel-air intake valves.
Sure - given that 2) is driven by piston rotation (passive valve operation), an ICE will stall at startup if there's a sizeable load resistance; but this is nothing that can't be mitigated by independent active electronically operated valves.
It's a nuance that I thought should find mention on the talk page, if not somewhere in the article.  — Preceding unsigned comment added by 220.224.246.97 (talk) 10:07, 7 October 2013 (UTC)
replies: text: The Paxman Hi-Dyne engine was an attempt to produce high torque at low rpm, but not at zero rpm. To start from zero rpm you need an auxiliary power source such as steam, compressed air or electricity. Biscuittin (talk) 19:59, 12 August 2015 (UTC)
replies: text: It is possible to use a Free-piston engine as a gas generator for a gas turbine so I see no reason why it should not be used as a gas generator for a second piston engine. The second piston engine could then start from zero rpm. Biscuittin (talk) 09:19, 13 August 2015 (UTC)
