Talk:Volumetric efficiency

From Wikipedia, the free encyclopedia

This article is not entirely correct.... there are many mass produced engines that run greater than 100% VE without forced induction.

The mass produced Honda H22 (Prelude, Accord, Ect) runs at 104% VE and does not have any form of Forced induction. There are also several production street bikes that run at greater than 130% VE.

I've never heard of sleeve valve engines failing due to "popping"...Generally, I believe their biggest issue is sealing oil.

Helmholtz resonators have been used after the 70's. Many cars today use them to remove drops in torque at a certain rpm (e.g. Honda gen. 2 L-series).
