Al +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Al, The RPM is controlled by the "prop" control and automaticly changes pitch to maintain that RPM, except at very low "power" setting where the RPM will drop below the setting selected. The manifold pressure ( MP ) is a function of the throttle position. A general rule of thumb is to not set the RPM below the MP or it tends to load down the engine. An easy way to understand MP is to think of the butterfly in the intake system. With the engine running, a wide open throttle allows in max atmosphere (30 PSI, sea level). At less than full throttle you are allowing in less then max available, i.e. 24psi at cruise. The prop is set so that flattest pitch (highest rpm) and full power (wide open throttle) only allows a max rpm, say 2750 rpm or so. When flying jumpers in the C-182, we take off with full throttle (approx 29psi) and prop control in flat pitch (approx 2700 rpm). At about 800 feet AGL I back off the throttle to 24 psi and then back out the prop control to 2400 rpm. With each 1000 feet of climb I lose one psi so I advance the throttle to regain that inch of MP. I can do this through about 6000 feet when full throttle gives me 24 psi MP. By the time I get to 10,000 feet I"m only getting 20 psi MP. On a hot day with a full load I've lost so much power that the climb rate gets down to 200 to 300 feet per minute, some days near zero, and you just kick out the jumpers. Aircraft with constant speed props have charts showing the power output of the engine with different MP and RPM settings. In the KR we can only control the MP with the throttle. The RPM is determined by the specific prop you are using. There probably is info somewhere showing the percent of power for the VW at various RPM and MP settings but I wouldn't have the slightest idea where to find them. Clear as mud?

One thing that may make a little more sense out of the explanation is when you refer to the product of throttle changes is if you would call the result of it out in "inches of mercury" instead of psi. As the correlation is related to the atmospheric pressure vs the pressure inside the intake manifold, which is measured in inches of mercury. Also, the prop governor holds the RPM constant, except for on takeoff roll where the prop low pitch setting actually controls the RPM until the reduced air load on the prop allows the RPM to increase to the redline of the engine, at which point the governor starts controlling the RPM. The same thing happens on descent when you retard the throttle to the point where the prop again contacts the low pitch stops, and for all practical purposes, you again have a fixed pitch prop. The use of a manifold pressure gauge is a much better way to control the output of an engine than just using a tach as the tach reading will vary with the air loads (climb vs cruise or descent) and also with pressure altitude changes.

Mixture control. I do not have a CS prop so throttle and mixture are my two variables. I have been reading the AvWeb Pelican Perch articles on leaning and am totally clear on his points. There is a region below 8000' that you should not run around peak EGT. It varies based upon percent of maximum power. I am not sure why the limits on rich of peak vs lean of peak are applied unless it is loss of power versus excess fuel consumption. Any thoughts? Ron Lee ------------------------------ Date: Mon, 24 Feb 2003 07:07:12 -0500 To: KRnet@mailinglists.org From: "Dana Overall" Subject: Re: KR> RPM / MP /Mixture Message-ID: Ron, if you are referring to all the articles about running lean of peak, you must be able to measure CHT and EGT of each cyl. plus be able to regulate the mixture for each one, thus GAMI injectors. Truly do try to run lean of peak without all of the above. Ron, if you want some reference to this let me know off the list and I'll reference you to some of the Bonanza material. I now enough about this to be dangerous but know where some good material is. WOW, 25" and 2500 RPMs at cruise...........Only kidding witcha but but to get that you gotta be low and only running on four cylinders to get 11GPH......at least in my Bonanza. Since my Bonanza is 200+ HP I have max RPMs for 1 minute on climb so I screw the prop out to lower RPMs and watch the MP decrease at altitude increases. The theory of running over square is a little over exaggerated, especially in low compression engines. You will not have to worry about this with a fixed pitch prop KR. With the MP guage and mixture control on a fixed pitched prop airplane, let's look at engine management from altitude down. At cruise up high, lean to your desired EGT and either see what your MP is reading below 8000', higher than that just know what MP to shoot for on your descent. As you pass through 8000 or start from whatever, set you desired MP and regulate it by decreasing throttle along the way. Maintain your EGT by richening as you go. It is really easy engine management rather than just chopping the throttle and point the nose down to shoot for a speed. As Larry pointed out with the jump plane, you will very likely run below the 75% power mark below 8000' as this is technically based on density altitude. Remember, it's not 8000' AGL. I really wouldn't go through all the trouble to calculate the standard lapse rate or checking the temp. at altitude unless you have the little wizz wheel on board, then heck, why not. Don't over complicate this, know a summer setting, know a winter setting and something in between or do some calculations and post you a little placard beside the MP gauge. Another way to look at this, for you cross country KR cruisers, (doesn't apply to high altitude guys who live with this everyday). You're taking off at gross at a high density altitude airport. A certified airplane has charts in the POH to tell you what your increased takeoff distance is and your reduction in climb performance. We don't have that luxury with experimentals. If you have a MP guage, open your throttle up on the ramp and read what the MP guage is showing. Compare this to what you normally see at your home airport. This will tell you the decreased engine performance you will have on takeoff and your decreased climb gradiant. HUM.......we're at gross!! They are great little gauges on a fixed pitch prop airplane and let you know a good reference point for your engine/prop configuration. They are not a magic Genie for your airplane but for reference, IMHO you can't beat them.

A lot of it was written up in Sport Aviation in the 70's & 80's. I'll look for it and post what I have from a presentation at Oskoksh in the late 70's.

Message-ID: When you run lean, there is excess oxygen, and it is corrosive. If only one cylinder runs leaner, it will be past the peak, while others are not, and you can reduce valve life. Especially a problem in homebuilts with poor distribution of fuel/air, like a slide valve carburetor turned 90 degrees so that the fuel droplets tend to go to one side. Why do some manifolds have a cylindrical enlargement at transitions?
