Lubrication is either by use of pre-mixed fuel and oil or oil injection from an externally mounted oil tank. Fellow 582 Rotax Owners or APOs! (The type E gearbox includes an integrated electric starter motor.) Four stroke sips very little fuel compared to 2 strokers. Usually idle air screw adjustment - 1/4 turn at a time or at worst the clip position on the needle - up one notch for leaner.

This time is also born out by infield experience. low rider, sky wheels 25' , pilot 165lbs average 4.7 gallons/hr and range 60 statute miles with 5 gallon tank 2 quart reserve. Thanks for the comments. They dont recommend it for prolonged usage.

The only problem with avgas in a rotax is the lead can leave a deposit on the sparkplug when you shut the motor down and make it hard to start. The Rotax 582 is a 48 kW (64 hp) two-stroke, two-cylinder, rotary intake valve, oil-in-fuel or oil injection pump, liquid-cooled, gear reduction-drive aircraft engine manufactured by BRP-Rotax GmbH & Co. KG. What you are burning sounds about right. I was trying to compare it to adverts for a Rotax 912 based planes where they generally quote 12-14 l/hr (also backed up by friends who have 912 based planes). Is it time to fly yet? Advice that I got from Avcom when I posted a similar query was -. This increased the displacement from 521.2 cc (31.81 cu in) to 580.7 cc (35.44 cu in), an increase of 11%.

I may be doing 5100 rpm but not at full throttle so the fuel consumption is lower.

You are using an out of date browser. I do have a fuel flow meter. Aircraft equipped with this engine must only fly in DAYLIGHT VFR conditions. What are other peoples experiences on fuel consumption on the 582? 582 fuel comsumption 582 fuel comsumption It's been a while since this post was made. First, when fuel is premixed with 2-stroke oil, the octane rating is reduced by about 2 points. Is it time to fly yet? ↳   Microlight Clubs, Training Schools and Flight Centres, ↳   Misasa, Aero Club, CAA and legislative issues. Engine prices, fuel prices, repair costs will have increased! An 87 octane fuel would therefore become 85 octane. In the PRA ground school we are learning about flight planning. When I raised the issue with Comet Aviation Supplies they immediately recommended a carb service. It uses a manifold-driven pneumatic fuel pump to provide fuel pressure.

K. O Rotax 277, 377, 447, 503, 532, 582 aircraft engine fuel supply and Mikuni fuel pump safety bulletins, advisories and alerts. It has not received any safety or durability testing, and conforms to no aircraft standards. Lorem Ipsum has been the industry's standard I have put about 70 hours now on my Raptor with a Rotax 582 blue top. Reliability over the 532 was also improved. It looks like the average fuel consumption is about 4 to 4.5 gallons per hour at 5000 RPM. The 582 has dual independent breakerless, magneto capacitor discharge ignition (CDI) systems and is equipped with two piston-type carburetors. Might get better fuel burn if its not a trike, but not much better. 5000/6500 = 77%.

As a matter of interest, did you move your wing at the hang point? I am concerned in that my Rotax 582 (silver top) fuel consumption rate appears to have increased gradually over the past six months. It is currently Tue Nov 03, 2020 11:09 pm. Thanks, I think the light has come on. They hold 10 gallons total. Rotax 582 UL DCDI 65HP Blue cylinder head, model 99 2-stroke engine specially developed for recreational aircraft 2 cylinders, liquid cooled Rotary valve - November 1, 2020 This is the recommended rebuild time as stated in the Rotax engine manual., Yes, let's go fly! I got a call from UPS, my 582 will be delivered in the morning. Looks like 4-5 gph is the best you can hope for during all around flying. Much cheaper as gasoline. This is much better than the Rotax manual states (20.5L per hour @ 75% continuous performance) so it is a pleasant surprise and makes me think Rotax is being ultra cautious (as opposed to the car industry which seems ultra optimistic). So that 75% figure in the manual has limited practical use. [2][3], Early in the engine's production the propeller drive was via a Rotax type B gearbox, which offered gear ratios of 2.0:1, 2.238:1, and most common 2.58:1. Rusty, your gear box and prop are all part of the equation as well. JavaScript is disabled. to top it back off. You must log in or register to reply here. It may not display this or other websites correctly. I just trying to relate fuel consumption with my gyro and I don't have any history yet for my engine. Tracy Crook, a long ago Sunstate gyro flyer used to say; “Fuel consumption in a gyro is no more relevant than a light weight tombstone.”.

No real 'danger' per se, but Rotax says you may use it as an alternative to Mogas if it is the only fuel available. Re: Rotax 582 consumption Carbon on the base ring is a rich idle setting.

Max RPM: Max Power: Max Torque : Fuel Consumption : KW: HP : NM : Ft Lb. It is for use in non-certified aircraft operating in day visual flight rules. You must log in or register to reply here. My engine is at 700 hours and I have never done a 'carb service'. Thats at a slow crusise of about 65 MPH. The true cost of gasoline and diesel fuel is about the same except diesel has slightly higher energy content per liter. The consumption might still be on par with others but YOUR engine is not the same so it needs to be invetigated. Rusty, When I had my AC 582 W/23' Skywheels, I weighed in at about 155-160lbs. The standard starter is a recoil start type, with an electric starter optional. It is all in how your flying, and how much power your trying to make. I have some notes from my old Kolb Slingshot with a 503, and I measured it's consumption between 4.25 and 4.75 gph. At 5000 RPM what is your fuel consumption per hour? Sorry, I should have added that the result will not necessarily give you % power of 64 HP, as this is dependant on prop pitch density altitude etc, but will rather indicate the % of available power. Dont worry too much John, it sounds fine. Are any dangers to running Avgas in the 2 strokes like Rotax, Hirth, or Mac's?

Expect about 5 gph at that power setting.

Re: 582 Rotax Fuel Consumption - advice please! I've heard a lot of people say they run autogas in them. User assumes all risk of use, and acknowledges by his use that he knows this engine is subject to sudden stoppage...Never fly the aircraft equipped with this engine at locations, airspeeds, altitudes, or other circumstances from which a successful no-power landing cannot be made, after sudden engine stoppage. I have seen fuel burn as much as 6 -7 gallons per hour and as low as around 3 - 3.5 gallons per hour. Does it made a difference if you have oil injection or pre-mixed gas and oil on fuel comsumption? The engine includes an intake air filter and can be fitted with an optional intake silencer system. It may not display this or other websites correctly. Gyro's are draggy devices, (I think Ken Brock said that) so fuel comsumption will be higher that that of a fixed wing, but you can directly control fuel useage by the throttle lever!

It is for use in experimental, uncertificated aircraft and vehicles only in which an engine failure will not compromise safety. If I run 85-90 it will burn more but always under 3 GPH.

If you say the fuel burn increased over a period then something changed or is changing. It would take about 4gal. It is recommended that the needle jet and jet needle of the 582 and 503 be replaced at 150hr intervals. Cooling is via an externally mounted radiator. My 582 is in theory using a similar amount of fuel but at a lower power output and efficiency. @2020 - All Right Reserved. some time ago we had a look at consumption and all 4 single seats tested , open frame, part podded , podded, dragon wings, rotordyne, 532, 582 etc, they all came out at close enough to 20ltrs per hour.

I burn a gallon every 25 minutes with HKS. Re: Rotax 582 consumption Some guys claim a lot better, but I burn about 4.5 GPH at a cruise of 80-85 MPH in my Avid MK IV with an 80 HP Jabiru for engine. Also what pitch and size prop are you using. 2 stroke rotax are fuel guslers. [3][4], The 582 features liquid-cooled cylinder heads and cylinders with a rotary intake valve.

For a better experience, please enable JavaScript in your browser before proceeding. The Rotax 582 is based upon the earlier Rotax 532 engine design and was designed for ultralight aircraft. Such crash landings can lead to serious bodily injury or death...This is not a certificated aircraft engine.
