Talk:Manifold vacuum

I redesigned the entry, and "the basics" and created appropriate links regarding air pressure. As a gasoline engine expert, I don't agree with everything beyond "the basics". But, I didn't want to stomp on the work of other's, and there is value in all that discusson for whomever wants to read it. Sattyam 17:29, 8 October 2005 (UTC)[reply]

I reworked much of the article for tighter organization -- like Sattyam, I don't mean to stomp on anyone's toes. Some of the paragraphs seemed to confuse manifold vacuum (inherent in the use of throttles) with venturi vacuum (inherent in the use of carburetors), so I corrected that too.

It's not true that the engine in the Toyota Prius has no throttle. Certainly it should throttle less, due to the valve timings and low-power engine, but the throttle is still there. --KJBracey 23:39, 23 November 2005 (UTC)[reply]

Re-edited out where someone modified an article to say that modern atkinson engines run without a throttle. If its a gas engine and in production is has a throttle. Most test-bed gassers have throttles as well excluding GDI test engines, but that has absolutely nothing to do with variable valve timing or atkinson.Theunchosen (talk) 12:26, 18 May 2009 (UTC)theunchosen[reply]
