The Lowest Revving Gasoline V12 Engines

from cars to aircrafts from trucks and tanks to diesel generators 12 cylinder engines have a very wide variety of use and they can be used from as low as one and a half liters in an f1 up to over 21 000 liters in the largest diesel marine engines most common of the v12s are in between many of the gasoline units not revving past 4000 rpm [Music] lincoln sapphire beats valve was produced by ford and essentially being a reworked ford flathead v8 using a narrower angle aluminum heads and iron pistons relatively being very small as a 4.4 lead to v12 it had two water pumps a single distributor with one coil per each cylinder bank and some rather deadly engineering failures the water passages were too small there was an insufficient oil flow or inadequate oil ventilation it did make a good power of 111 horsepower with a flat torque curve it was eventually made in a 267 292 and a 306 cubic inch versions followed by cadillac the wheat felt was made alongside the v16 and shared many things with the 16 such as a v-angle overhead valve setup or a production period it was rated at 145 horsepower at 3400 rpm using twin carburetors and developed at a time when engine had to look good so all the plumbing and wiring was hidden to expose the bare beauty of the engine itself although the v12 made about 40 horsepower less than the v16 it actually performed better in the car as the whole car was lighter had a better handling and also it was cheaper with a 35 lower price tag about 3790 dollars in 1931. [Music] the next one ranger v770 was an aircraft engine developed from an inline engine being an inverted v12 made from various materials but mostly aluminium such as a two piece crankcase heads cooling things with steel cylinder liners there was a gear driven single overhead cam per bank and a single stage supercharger similar to other inverted v12s it provided a great visibility outside from the cockpit but it had its drawbacks like a low speed overheating issues the continental av-1790 was a range of gasoline and diesel engines all sharing the same engine displacement of 29 litres it was air cooled with two large fans at the top but it was not only meant for aircrafts but also heavy battle tanks and other military vehicles the av stands for air cooled with a v-shaped design and the 1790 actually means the displacement in cubic inches the gasoline version made about 810 horsepower using 80 octane fuel with a carburetor while a diesel variant actually had 1500 horsepower at similar rpm maibak hl-230 was also a battle tank engine and it was also burning gasoline germans actually powered the largest tanks with it alongside its smaller variant hl210 the 210 was an aluminum engine while the 230 was actually made from cast iron with a cumulative weight of 1200 kilograms using a carburetor it could develop up to horsepower at 3000 rpm and later with a proposed fuel injection supposedly up to 900 horsepower at atmospheric pressure [Music] packard has a history of different video pensions ever since early 20th century some automotive units a 1500 and also a 2500 cubic inch air engines the smaller 1500 was only made in 29 examples while the larger one the 2500 was built in 258 examples with various versions having 800 or 900 horsepower some with supercharging producing 1500 horsepower or a marrying unit for torpedo boats one of them even found its way into a packard bentley car [Music] the famous daimler db series was a very popular german engine making from constant 780 horsepower up to 1800 takeover horsepower there was at least 60 000 db series engines produced altogether and actually it was another german direct competitor to a different american engine it was so good that japanese actually bought a license and built it under the name kawasaki ha-40 and a aichi atsuta the db series started production with a carburetor but due to fuel starvation at extreme lows a fuel injection was proved to be a better choice so the 601 and newer versions actually used a mechanical injection it grew from over 30 liters of engine displacement up to 44 liters using centrifugal supercharger during ejection and a 1510 continuous horsepower an interesting feature was that a one bank had 7.5 to 1 compression ratio while the other one had a 7.3 to 1. so [Music] [Applause] the rolls-royce meter was actually a scrapyard engine the story is that rolls-royce had a many crashed merlin engines and they were unsuitable for another aircraft usage so they developed a tank engine and on-road engine from it called meteor they removed the two-speed supercharger and the high octane fuel was not required anymore but it kept the overhead cam setup the meteor provided much better performance than prior engines in these applications and so with a better performance they could load up the tank with a more armor [Music] [Music] aircraft engines were always high tech and the liberty l12 was no exception in 1917 it actually featured a single overhead cam driven by driveshafts a two-piece aluminum crankcase split at main bearings and cast iron cylinder liners it used an ignition from delco and carburetors from zenith being mostly an aero engine but later it got marinized also with a slightly lower compression ratio revving up to 1800 rpm the lowest revving beatfall pension on this list is the bmw 6 brothers the bmw 6 was an aero engine very important one for germans made in thousand examples the origin was found in the bmw 4 as they merged two inline 6 engines into a single crankcase boosting its power from a maximum of 250 horsepower threefold up to 750 horsepower the cylinder stroke was different per bank due to articulated controls but other than that it was a typical aero engine with twin valves per cylinder using overhead cams twins and carburetors and not so typically water cooling one of them a very popular usage of this engine actually got later installed in a beast called brutus which was using a 1907 chassis if you like this type of content please subscribe many of you are not subscribed who are watching so if you do like this content please do so thank you very much for watching and see in the next one cheers you
