The O-320 operator's handbook shows a graph of fuel consumption vs RPM. Disadvantages More moving parts, more costly to maintain, and more difficult to start when hot. I seem to have a peak EGT of about 1350 during cruise. Direct injection of fuel into cylinders offers better fuel distribution and easy cold starting, without the threat of carburetor icing. That is, stroke is markedly less than bore. Dry weight is 804 lb. You can pretty much run the 320 any old way, it's one of the most indestructable engines ever made. Preflight O-360 and IO-360 Fuel tanks and strainer— sample for clean fuel. The graph is "S"-shaped: [from memory] at the steep part of the curve an 8% increase in RPM can cause a 27% increase in fuel consumption. It will gain you very little speed, but will cost you a good deal more for fuel. depends on how much you are filling it. It is therefore recommended that operators of all Lycoming aircraft engines utilize the instructions in this publication any time the fuel/air mixture is adjusted during flight. I get a level of comfort flying behind a Lycoming engine. Example:Flying at 25.1" MP, 2400 RPM, 2200 ft and at 75° F outside air temp the engine should produce 139 Hp on a standard day (HPs).

I do find that if you are doing a lot of takeoffs and rpm changes all of the above are true, but if you set off on a long cross country, that you will sling a lot less oil even if you put in a qt or so more than the 5.5. also when in the extreme summer temps of the kansas, neb , dakotas, having more oil in the sump helps maintain oil temps at a resonable temp. We used to run 30" on the Pratts quite a bit. I thought for 4-place planes, the … Cost saving led to minimizing the size … All modern light plane engines of the opposed cylinder layout are over-square. Using that on the 180 hp is 180x.75x.49/6=11gph in cruise lean at 75% power.

Unfortunately, the engineering compromises made in the valve train resulted in camshaft lobes and associated lifters that were quite corrosion intolerant. or Best Offer. I Know if you want to learn something , you better ask someone with some time and experience,the book just gives you a general idea . I blocked off the prop Governor with the available Lycoming block off plate. He tells me he runs it on the redline most of the time and always gets TBO or better. The inverse of efficiency is specific fuel consumption. I run my O320 between 2400 and 2450, where it runs the smoothest. To obtain the desired power, set the manifold pressure and RPM according to the power setting table in this manual. Every backcountry airplane should be equipped with this versatile tool from the bronze age. All modern light plane engines of the opposed cylinder layout are over-square. That's exactly it. I am aware that the O-360 STC is available but the O-320 is available a lot cheaper than the 360 and it seems an obvious choice with parts for the O-300 getting harder to find. In cruise I had slightly increased speed per rpm and could just reach red line (2700 rpm) with my Lycoming O-320 160 hp engine. if you are going over 2700rpm redline you´ll probabely crack your valvesprings(on a normal O-320 or O-360). The fuel injection system schedules fuel flow in proportion to air flow and fuel vaporization takes place at the intake ports. In most cases you will be best served by using the range at the bottom part of the "S," just at the point of the curve where it starts to climb steeply. 320, 360, 470, 985, there's just some engines that seem to take a lot more than others and those are a few. If the engine ran at low RPM all its life, then sticking a high RPM prop on it could cause you grief. They have proven to be both economical and practical by eliminating excessive fuel consumption and reducing damaged parts replacement. C. Is the oil being heated by combustion gas blowing past the piston rings? A: Alan, if you do have, in fact, a Lycoming O-320-E2D, you don’t need to go any further as the answer is simple.
