Applications power figures

The application lists have had some extra lines added containing just power figures. Are these figures for the single line above them or for the group of lines below them? Quite confusing. Stepho talk 12:05, 12 October 2020 (UTC)[reply]

They should be the groups above them will try to space them out so they arent as confusing TheBitterNoob (talk) 18:16, 13 October 2020 (UTC)[reply]

2L subfamily

The new data for the 2L subfamily of engines seems full of erroneous figures. The website cited appears to be Toyota, bit does not match the data put out on other toyota websites and publications. Is it possible the website is mistaken? For instance, the 2LT-E engine first appeared in 1988, for 1989 model year vehicles. The claim that it was introduced in 1982, 5 years before bosch released the first electronically governed injection pump, is one of several questionable parts of the section.

@Shinhoto: I don't know, there are several sources that refer to the Crown receiving the electronically injected 2L-TE in 1982, and they look very legit to me. There is a note in the timeline for August 1988 that says "Diesel pilot fuel-injection system, a world first, adopted in the 2L-T engine", maybe that's the development you are thinking about?

The pilot injection note refers to the adoption of semi-throttle injector nozzles.

It seems impossible that Toyota was using electronically governed injection pumps 5 years before they were invented. Shinhoto (talk) 01:06, 19 November 2020 (UTC)[reply]

Check this out. I guess what we need is an article that defines what electronically injected signifies in these two cases. Best, Mr.choppers | ✎ 01:08, 19 November 2020 (UTC)[reply]

It seems that the ECD pump design used in the Crown is based on a mechanical ve pump but uses a solenoid to actuate the spill ring to control fuel quantity and a valve for timing according to the Toyota's 1983SAE paper (well the first two pages of it)] on the Crown's ECD system as well as their 2nd-Generation ECD system's(can post a working sci hub link for this one if that's allowed here) paper published in 1986, describing replacing the solenoid setup and adopting a start of combustion sensor.Isuzu's 4FB1 I-Tec seems to be another early ECD application with a proposed Autumn 1982 release in japan according to their 1981 paper narrowly beaten by the 2LTE's August 1982 release date if toyota's 1986 paper is correct.
