Talk:Idle (engine)

“Myth: restarting the engine causes greater engine wear than idling. Reality: restarting causes less.”

Actually it isn’t a myth. When starting the engine, mixed-film lubrication occurs and a pace of wear is hundreds times greater than in case of hydrodynamic lubrication. Especially in industrial applications, which are not meant to be restarted on a regular basis. 94.229.219.101 (talk) 22:31, 2 February 2015 (UTC)

"Cars need to idle to warm up the engine: Actually, the engine warms up faster when being driven." In this sentence is that problem, that it is totally taken out of the context, engine doesn't need to idle to warm up, but engine should be warm before putting it under heavy stress. Especially turbodiesel engine should let idle for awhile before driving; one reason is that, turbo does not get oil right after the start. Other problems are related to thermal expansion. 80.221.251.172 (talk) 21:21, 4 June 2012 (UTC)

All engines can idle. Not just cars. A generator can idle. A weedeater can idle. — Preceding unsigned comment added by 73.131.146.228 (talk) 04:37, 19 October 2019 (UTC)

In what place does 30°F constitute winter? Hawaii? Casablanca? Cairo? That's spring-jacket weather. A better figure would be -30°F.

30 °F is about -1 °C. In many areas near the sea, temperature does not go many degrees Celsius above or below 0 during winter. A winter temperature of 0 Celsius is therefore of great interest. However, I would agree that a separate table for minus 30 Celcius also would be interesting. Sauer202 (talk) 15:55, 11 May 2021 (UTC)

Reference 30 in this article is a permanent dead link:

This is cited in the sentence: "The DOE is funding research and development for alternative and advanced vehicles, which includes the gathering of quantitative data on medium-duty trucks, examining idling reduction alternatives, and the CoolCab project for semi-truck curtains and installation."

A working replacement covering DOE idle reduction research, quantitative fuel consumption data for medium-duty and heavy-duty trucks, idling reduction alternatives including the CoolCab programme, APU comparisons, and engine-off policies is available at:

<<link redacted>>

The page includes a dedicated section titled "The Fuel Cost of Depot Idling: Data, Alternatives, and What It Costs Your Fleet" containing idle fuel consumption figures by vehicle class (medium-duty: 0.8–1.0 L/hr), a description of the DOE CoolCab programme, APU fuel consumption data (0.25–0.4 L/hr vs main engine), and engine-off policy guidance.
