: camless engines.
Land Crusher 05-23-2002, 10:07 PM I was sitting on my fj 40 front fender talking about needing fuel injection when a frend
handed me a beer and started telling me
a very interesting story.
basicaly International is going to make
a engine for ford for 2003 that doesnt
have a cam.
The valves will all be controled
buy a computer maybe direct injection also.
Probubly a cvt soon.
I wonder how it will do in water crossings
Shit does this means I should be nicer to Medusa.
:beer: :beer: :beer:
Chief yelling alot 05-23-2002, 10:11 PM ahhhhh yes good old IH
yeah I have heard that too but it wasent for IH but what it is is very strong solonoids
wonder how well it going to work
maybe i'll look into that, My uncil works at the local International delership and it's not to far from work
Lord Baskerville 05-23-2002, 10:15 PM These engines have been being tested for a few years now.
I expect that I will be teaching my classes all about how camshafts used to be used to control valves back when carb still were being used.
They work and will must likley be in all engines in a few years.
Maybe 10 years ????

I rember about 5 years ago when I was in auto mechanics in high school my teacher was telling us about them saying they would be the new thing for 2000 (heh here we are in 02). Sound pretty sweet you could just dial in whatever degree and lift you want whenever.
Toyman 05-23-2002, 10:29 PM Wow! Cool! I thought about that about 10 years ago, it's cool to see that it's finally going to happen.
Land Crusher 05-23-2002, 10:36 PM That brings up the question why do we need
4 stroke why not a 2 stroke with valves ??
ps did some research and intell is going to make
a pentium chip just for the auto industry.
Just imaging the fun of wiring that SOB into a rig, or if a solenoid started getting weak...Or failed on the trail....
drnut 05-23-2002, 11:43 PM Well solenoid would not be that hard to wire in or replace at all. It only needs 2 wires to make it operate. Its either on or off and that is it. I think this would be a great idea. The only problem is getting a solenoid that would work for a very long time with very high temps. I would like to see this in the future. I think this could be a new age of some serious perfromance engines. When you loose the camshaft you are able to loose alot of friction and drag to the engine. This could open up so much for the auto industry it would be amazing!!!
smasher 05-24-2002, 08:04 AM Actually your friend is probably getting that from places like this
http://www.mrtruck.net/news.htm
I dont know where they got their information from but the 6.0L Ford diesel is not a camless engine.
It is, however, bad ass and rated at 350hp and 600ftlbs. from the factory.
And it is direct injection.
:usa:
Explorer 05-24-2002, 08:14 AM I've always been a proponent of camless engines. Imagine the flexibility! Program in a cam that would idle like a stocker, have awesome low end torque and then crank in the lift and duration for amazing high RPM horsepower :D It would all be just a matter of programming the computer to change the valve timing and lift in relation to RPM and load.
Can't wait till that type of system gets the bugs worked out.

I think I'll just turn my license in now... :flipoff2:
Savage 05-24-2002, 08:21 AM I'd say it would be easier just to have a switch with three positions. Something like stock, strip and tow.
Priest 05-24-2002, 08:22 AM F1 has been using a vairation on this for some time now. Pneumatic valve trains and some of the teams are currently testing electro-magnetic valve trains as well. When your spinning close to 20K RPM a mechanical valve train just won't hack it.
Also, a few years ago I remember hearing that Jacko Johnson was working on a motor that didn't have any connecting rods. The pistons rode on cams. He was calling it the Power Ring 3-Stroke. Anyone else remember that?
kodak 05-24-2002, 10:27 AM I was going to say that F1 has had this for some time. but they piss wine the motors v10 with redline at 27000.
so how does a 3 stroke work
suck, sqeeze, blow: repeat

strong_like_tractor 05-24-2002, 11:09 AM It is my understanding that camless IH diesels won't appear on the market until 2007. This was discussed quite a bit on Ford-Diesel.

CaptainFleXJ151 05-24-2002, 11:20 AM A few F1 teams have been using this technology because of valve float at high RPM's (18,000+)
BMW is set to release an F1 inspired V10 into the next generation M5 & M6, which is said to have a camless valvetrain. It should be the first production unit ever!
Explorer - I am with you on this one too. For years I have dreamed about a camless off-road engine. How nice it would be to idle around the rocks making sick bottom end, then when things get a little less sticky you can kick it to the high RPM's and pour on the HP. :D Then once you are on the road dial it back for gas milage. This would all require some type of stand-alone enigne management, like a Motec unit.
fj40guy 05-24-2002, 12:32 PM The engines have been around for a while.
Along with "camless" you'll have to also notice that gas engines suddenly don't have a throttle any more (I thought it was a diesel due to the missing throttle body).
Also no need for an EGR valve, as you can regulate the "partial throttle" which controls the amount of EGR in the cylinder.
Sorry, not Intel for the controllers on those. Intel is heavily going after the "PC in a car" market, along with other folks.
If you do a search on MPC555 -- that is the motor controller chip used for quite a few applications of the camless engines. Ya, in a former life I headed up the apps team on that for a large company. Great folks, loved the work, hated the Politics. Sorry, I signed lots of NDA's so will not discuss any details, but had a blast working with lots of folks in Detroit, England, and Germany on the controllers and their projects.
Funny one on ISAD (Integrated Starter Alternator Damper) -- basically an electronic flywheel that acts like a starter/alternator at the same time. Test drove a prototype 50 hp diesel (small sedan) fitted with the system. The battery storage allowed the ISAD to dump 70hp into the system for up to a minute (think of hitting an onramp or passing a car). Suddenly that little Ford just screamed! Way too much fun. Also think of having 200 ft-lb torque at 100 rpm for rock crawling (you need more batteries, but you get the idea). Also you could kill the engine on this guy, while at a light, tap the clutch back in... and you are at 700 rpm in less than 100 milliseconds. In Europe you'll see sweep hands on the red lights to tell you when to restart the motor.
Oh the D part of ISAD: Had a noisy diesel on the test stand. Flipped on the ISAD system to dampen... and thought I was next to a SMOOTH gas engine (dead quite, no vibration). Turn the system off, and it was rocking back and forth on the test stand.
Then again with the 36V systems we will see lots of other interesting things to come.

Grim Reaper 05-24-2002, 12:57 PM There is been one available for years! it's called the Wankle Rotory motor. The Rotor acts as a valve by the way it rotates in the housing. Sort of the same way as a 2 stroke. They turn 10,000 rpm no problem on the production models that were available in just about everything Mazda made in the 70's including their trucks. A hopped up one with custom seal will turn 12k. the love turbo chargers. You can easily make 400 HP on them. Pretty amazing for an engine rated as 1.3 liters of displacement :) They are light enough that the average man could carry them with the accessories removed.
gunracer1 05-24-2002, 01:02 PM didn,t cadillac have a motor the v4/6/8 that had some electric valve that would work when needed or am i just remembering a bad dream. this was about 1980 or 82 don't remember those years to well. mike
coyote11 05-24-2002, 01:44 PM Yeah the Caddies had the 4-6-8, at least that is the the consensus at my place of buisiness. They didn't last long in production from what I heard, must of had some problems, but I don't know all the details.
CaptainFleXJ151 05-24-2002, 03:32 PM roundrocktom - I have heard of the alternator/starter/flywheel setup, but it was only for automatic transmissions that could restart at the tap of the throttle.
Grim reaper - I believe the only way to make power on that Wankle motor is to go with forced induction. That sort of setup wouldn't be desirable off-road.
This would all be fun, but when it comes down to it most 4 wheelers are not in favor of things being controlled by a computer. I think the market for this is more in high performance cars and heavy duty trucks.
RHINO 05-24-2002, 09:44 PM i believe it was detroit rather than IH that has been testing them. i know detroit has a race truck, pikes peak hillclimb and other stuff, it does great, makes more power and less smoke and seems to be real reliable.
