Talk:Turbo-diesel

Untitled
I believe that this article should not redirect to turbocharger both because there is more to a turbodiesel than the turbocharger, while redirect is best used for synonyms, and because the content of the page did provide useful information not found together in other articles.

page has wrong information
turbo diesels have been used in the states for years, since the 70s - 80s eg detroit diesel

Like most of the combustion engine technology articles it focuses exclusively on passenger car/light truck applications and utterly ignores industrial, agricultural and freight transport applications. JE1977 (talk) 01:43, 4 March 2008 (UTC)

And neglects to mention that VW and MB have been selling turbodiesels since about 1989.169.226.78.145 (talk) 19:34, 27 May 2010 (UTC)

Turbochargers vs Superchargers paragraph
1: Since this data is not particular to turbo/super charged DIESELS, this paragraph should move to a turbo.vs.super page/location. 2: This paragraph seems to be personal opinion, and, if not moved, should be removed. AnotherMadPenguin (talk) 15:52, 22 April 2018 (UTC)


 * @ I have removed the paragraph per WP:NOR. Best regards, --Johannes Maximilian (talk) 12:16, 2 February 2019 (UTC)

Scania and turbodiesels
With the present wording, the article imply that Scania put turbodiesels into their trucks in 1954 and that they where the first to do so. Perhaps the Scania-Vabis DS805, a straight-eight that powered the SJ Y6 railcar, was the first high-speed (high-rpm) turbodiesel. But that engine was never fitted to a truck. Instead it was MAN, that in 1951 fitted a turbo to its MK 26 model that were the very fist. In 1953 for the model year-1954 and with MAN 750 TL1, they where the first to introduce a series production turbodiesel truck. It was not very successful, it proved to be unreliable had very bad sales. A very few was built and when MAN introduced the equally powerful 758 L1 in 1954 with a large-displacement engine instead, it effectively killed the sales of its turbocharged brother completely. Volvo's attempt was more successful and from 1954 their Titan truck was available with turbo. This was the first volume production series turbodiesel truck and gave Scania - the most popular manufacturer of severe-duty trucks on the Swedish market at the time - a run for their money. Scania introduced a new 10 litres diesel in 1958 [D10], but it was not until 1961 that the turbocharged version [DS10] was available in a truck (the L75 Super).

 * Seems correct, although it could probably use a better source than MAN's own website if available.  ⊂&#124; Mr.choppers &#124;⊃   (talk) 15:36, 13 May 2012 (UTC)

Diesel Locomotive Turbocharging
The first production diesel locomotive in the United States built with turbochargers was the Alco HH900. The first HH900 was built in early 1937. Alco had been experimenting with turbocharging diesel engines since 1933. See Chapter VI of The American Locomotive Company A Centennial Remembrance by Richard Steinbrenner. --SSW9389 18:04, 15 July 2013 (UTC)

 * Naturally aspirated Diesel engines are similar in engine speed to turbocharged engines, the speed difference is negligible
 * Naturally aspirated engines do not produce much torque ("strong" torque doesn't exist I reckon) at low engine speeds, because their cylinder charge is not as good as in turbocharged engines
 * Power is the quotient of work and time; if a petrol engine and a natually aspirated Diesel engine both run at the same (=equivalent) speed, but the Diesel engine produces more torque, it is going to produce more power, not "significantly less" power.
