    Fun fact! The design of the flat twin engine in the citroën 2CV was actually based on BMW's flat twin engine design. They even sound similar. So much so that swapping the asthmatic 2CV engine for an actual (and more powerful) BMW engine is supposedly quite easy.

    • @davidpowell3347
      @davidpowell3347 Рік тому

      The lack of a modern V8 until 1955 is often cited as the reason for Packard's failure but those straight 8s through 1953 or so were quite competitive with more horsepower and smoother running than such as Oldsmobile's new V8 although the new tech Olds engine was probably not much more than half as heavy (and cheaper to build) than the Packard engine
      I think the cause for Packard's failure must be looked for elsewhere such as having a GM man inside the Eisenhower administration in a position to cancel Packard's military contracts ,also Packard's terrible automatic transmission problems. (If I were a wealthy car collector/restorer I would want a Packard with the manual transmission and overdrive)

    here is what wiki has to say about the 90 series
    Series 90[edit]
    The second generation of V16 used an unusually wide vee-angle of 135°, giving a wide but much lower engine to suit the styling tastes of the late 1930s. The two carburetors, one on each bank, and air cleaners were mounted on top of the engine block in this design. These engines had 'square' proportions; bore and stroke were both 3 1⁄4 in (82.6 mm), giving an overall displacement of 431 cubic inches (7.1 L). Cadillac rated these engines at the same 185 bhp (138 kW) as the previous series. These engines were known as the Series 90, as were the cars that used them. The Series 90 V16 was produced from 1938 through 1940.
    This engine was used in the 1938-1940 Series 90.
    The 431-cubic-inch displacement 1938-40 Cadillac V16 was one of the last new American auto engine designs prior to World War Two. As such, it incorporated some of the latest thinking. Nine main bearings provided a crankshaft main bearing support between each 135 degree opposing pair of cylinders. The square bore and stroke lowered piston speed and promoted crankshaft rigidity, no small matter for an engine with eight cylinders in line per cylinder bank. The side valve engine design was no handicap for the time because the era's typical top engine speed of 3400-3700 rpm provided little opportunity to exploit the high speed breathing efficiency of overhead valves. Luxury car drivers presumably valued smoothness and silence more than high speed power. Hydraulic valve lifters promoted silent running and an absence of periodic adjustment. Unlike most cars of the era, an external oil filter safeguarded the precision valve lifters. Despite the use of side valves, the engine produced as much power as the prior 45 degree V16, and with much less complexity. The earliest engines produced featured an innovative friction wheel drive to the generator. This was soon replaced by a conventional V belt drive. Cadillac claimed that the 1938, 1939, and 1940 Series 90 Sixteen had the best performance of any production car in the world at the time and would accelerate 10-60 in high gear only in 16 seconds. The definitive engineering report on the 135 degree Cadillac V16 engine is "The Evolution of the Cadillac Sixteen engine," by E.W. Seaholm, in charge of Cadillac engine design. It was published by the industry journal "Automotive Industries," November 27, 1937.

    1953: 3.6L 65hp V8? cool collection of clips, never seen a running open piston and valves before.

  • @Tom-Lahaye
    @Tom-Lahaye 6 років тому +20

    Torque of a NA engine is largely dependent on engine displacement, but also om compression ratio.
    The higher the compression ratio, the more fuel you can burn in a given cylinder displacement, the bigger the bang, giving a higher peak combustion pressure.
    And this higher pressure on the piston surface in effect gives more torque.
    Power the other hand is determined by the amount of torque in relation to engine speed (rpm's), imagine having an engine with constant torque (which doesn't actually exist), running at 2000 rpm giving 100 hp, in this case doubling the rpm to 4000 with the same amount of torque would double the power to 200 hp.
    As most of the shown engines are from the pre WW2 era these were developed in a time when octane levels in fuel were pretty low, limiting compression ratio to around 8:1 at best (some engines in the video do 5:1)
    The lack of torque could be overcome a bit with a long stroke, so most of these old engines were undersquare engines, having a stroke larger than the bore.
    The flaws of the flathead design, being a poor combustion pattern, combined with lower standard materials and the long stroke limited engine RPM.
    This all explains why these engines are quite low in performance figures, as modern NA engines are in the 11:1-12:1 region.

      today with better fuels etc. we get torque by doing the reverse, piston area has been increased and stroke shortened. most cars only run at around 7.5 or 8.5 to 1 ratio's here in the us, thats why toyota's 3 liter v-6 is affectionatly called the 3 point slow and gets worse mileage than a 350ci v-8!
      when I look at what is available in other countries it makes me want to pout! light zippy little cars getting 50+ mpg! I would kill for one of those here!!

      L-heads were a good choice with the poor fuels of the early decades. It is easy to remove the cylinder head and decarbonize a flathead. The valve train is super efficient - very light and direct acting. The valves do not shroud the cylinders so the valves can be very large. But with the exhaust close to the upper cylinder wall l-heads can be tough on piston rings - motor oil cokes on that side and breaks the rings. The other side of the cylinder is cooler, this warps the head and causes the head gasket to fail. I'd like to see a flathead with the cylinder head cast in place - the pistons inserted from the bottom. That would prevent blown head gaskets and allow a flathead to work better with a supercharger. The valve casting would also have to bolt on from the side of the motor. A headless flathead.

      The main reason for Flatheads generally was simplicity , and resulting price points . So far was the Ford Flatty specifically , add light weight, and compact .
      With the low octanes requiring 5:1, 6;1, etc compression ratios , the flathead's inherent trade offs of flow vs compression were mostly masked .

    I've had two Dodge pickups with the inline 6: a '49 Heavy Duty and a '51. I hauled a 32-foot house trailer from Portland, Oregon to Victoria BC with the '49. Also, a high school buddy of mine had a '48 Dodge coupe with a '51 Chrysler 6. It was bored out, had dual carbs, a split exhaust manifold and a 3/4 race cam. That engine had a real nice ring when he wound it up. Sad to say, the Chrysler 6 was eventually replaced with a small-block Chevy V8.

The Harley's that had total loss oil systems with the old board track racers from the 20s. The Flathead did have an Oiler for its drive chain which always left a puddle of oil every time you parked the bike. they also kept making that 45 motor past 1969 into the seventies. They use them in the servi-car trikes, that the police used. They also had kind of a neat Flathead sportbike called the Sportster back in the 50s. Fun fact it was Harley's first working rear suspension motorcycle. Thanks again for the great videos please keep them going.

    There is a new production side valve engine that uses a central small puck on top of the piston center that fits into a recess in the cylinder head. The intake valve is outboard of the exhaust valve so the incoming charge cools the exhaust valve. Look up HCCI at Autoline network for an interview discussing this engine.
