Spacers

Toyota VVTL-i does not use a separate cam shaft for changing the lift of the valve. There are spacers that are slid between the cam lobes and valves by the ECU via oil pressure at higher RPM. Translating to the high the RPM of the motor, like 6000 in the celica, the greater increase in HP.

Triple VVT-iE

For the recent addition of 'Triple VVT-iE'. Google can't find that phrase at all (except for this article). We have no proof that this name has ever been used. Do you have a reference? What is your reference for "VVT is the heart of every modern toyota!" ? Which CEO said that and when. We need to be able to verify this stuff. Thanks.

Massive additions by 78.163.191.154

78.163.191.154 has made massive additions in the last week. I thank him for his energy but his enthusiasm has led him to add a hodge-podge that is hard to read and hard to edit.

Squeezing everything into the tightest possible wiki mark-up makes it very hard to edit. Intelligent use of spaces and blank lines makes it far easier for future editors. 78.163.191.154 has taken effort a number of times to remove this spacing for no benefit.

The section headers "Used models" and "Applications" doubles the size of the table of contents but doesn't add anything for the user. Instead, it complicates the user's experience. Not needed and not useful.

The long, long, long list of sections for models that use VVT-i lists model names but not the generation. Many of these model names have continued for decades - some with VVT-i and some without. So the model list is not very useful. It can also be argued that it would be better to list engines that it is used in rather than models.

The section headers contain a list of power output in hp. Utterly useless. And many readers understand kW, not hp. Clutters up the article for no benefit. Power figures are better in the engine articles and definitely not in section headers.

Finally, these lists require continuous updates as new models use VVT-i. This is the type of thing that categories are much better at. Each model article (preferably generation specific) simply adds the VVT-i category at the bottom of the article. Readers can then click on that category and see the entire list of vehicles with VVT-i. Alternatively, we could do the same thing to engine articles instead of to models. Far, far easier to maintain and probably easier for readers because the category would be reachable directly from the articles. Stepho talk 22:49, 27 June 2024 (UTC)[reply]
