Continentals, at least the smaller ones, have the right mag firing at the top plugs and the left firing the bottom. Both use fixed-timed dual magneto ignition systems,and valve trains with overhead rocker arms, shrouded hollow pushrods, and hydraulic valvelifters. What would happen if a 10-kg cube of iron, at a temperature close to 0 kelvin, suddenly appeared in your living room? That standard is now the norm. It turns out that multi-vis oil is not a better lubricant than single-grade oil.It’s actually a bit worse. Thanks for contributing an answer to Aviation Stack Exchange! Rather than give up owning an airplane entirely, some owners are stepping down into airplanes that can be maintained without worrying about a giant unexpected engine repair bill. Both should be economical to operate. Think of published TBO as being similar to published human life expectancy. Use MathJax to format equations. Because the market for Experimental aircraft has grown to be such a significant portion of the new-airplane world‭, ‬Lycoming and‭ ‬Continental have established their own in-house boutiques‭ ‬to provide non-certified‭, ‬often custom‭ ‬engines to the Experimental market‭. It’s proven to be the most reliable airplane I’ve everowned: reliable, efficient, and almost completely trouble-free. In February 2012 Continental received a 200-400 hour TBO increase on most factory produced engine models. Lycoming numbers them front-to-back, and the staggering of the cylinders is opposite between the two. I installed and maintained a Rotax 912 80hp engine in a Zenith 701. Experience seems to indicate that oil consumption lower than about a quart in 20 hoursmay not bode well for long cylinder life. Be the first to know what's new, in the air and on the ground. So if the gauge reads 240F, the oil is probably hitting close to 280Fat the hottest point in its circuit through the engine. Certainly, we don’t arbitrarily euthanize people whenthey reach the average expectancy age!

That means picking an airplane with an engine that either Lycoming or Continental got right from the beginning or fixed as the model matured. If we don’t get rid of this water the next time we fly, there will be a progressivewater build-up inside the engine. Finding sum of all pixels in raster using QGIS, Table with vertical text, and \multicolumn. Continental numbers their cylinders back-to-front. Sign-up for the Lycoming Flyer E-Newsletter. Now, it’s true that most turbocharged engineshave a lower compression ratio than their normally-aspirated counterparts (typically6.5-to-1 vs. 7.5-to-1), and that the turbo will burn a bit more fuel at any given powersetting. Every time we shut downthe engine, a slug of water condenses inside the cooling engine and runs down into the oilsump. Since then I’ve owned a succession of airplanes, and each one-quitecoincidentally-was powered by a big-bore Continental. When I explained, he told me it was unnecessary. Now suppose you turn over the prop by hand. It only takes a minute to sign up. That’s why lead fouling problems tend to emergewhen CHTs are below about 300F. Learn More. What about cylinder head temperatures? — typically cost $100 to $150/hour tofly, you can see that the difference is chump change. I still maintain, however, that the only way to replenish the protectiveoil film is to fling large quantities of oil around the innards of your engine with greatvigor. It’s worth pointing out that all these statistics almost certainly undercount the actual number of engine failures, since they only appear in these reports the result is an accident.
