0.24 -> In today's video we will analyze the
formidable engine of the Volkswagen Beetle.
5.4 -> We will see what was its key to success and why
its manufacture continued for more than 65 years.
12 -> As a first measure. This engine
was a 4-cylinder boxer with 985
16.62 -> cubic centimeters or 60 Cubic Inches.
Ferdinand Porsche designed this engine
21.66 -> to rotate at 3,000 RPM and achieve
the great power of 23 Horsepower.
27.18 -> Unlike Henry Ford. Porsche preferred
oversquare engines. This means,
31.68 -> with wide pistons, short stroke and higher
RPM, getting more power from a small engine.
37.14 -> Almost the entire motor is made of magnesium
and aluminum, achieving low weight and
42.3 -> excellent heat conduction.
The crankshaft and
45.18 -> connecting rods are made of steel.
Its compression ratio was 5.6 to 1,
49.98 -> which allowed the engine to operate correctly
with the lousy German fuels of World War II.
55.38 -> This engine had the rare opposed cylinder
configuration and used a single camshaft
60 -> to drive both banks of cylinders at once.
The gear kept the camshaft turning at half
65.34 -> the speed of the crankshaft, with total
presition and its lasted for life. Chains
70.2 -> or toothed timing belts were not used.
The camshaft location was below pistons
75.42 -> and received good lubrication from
oil falling from the cylinders.
82.14 -> The oil pump was directly connected to the
camshaft to drive the fluid under pressure.
88.32 -> A radiator which was in the air
ducts was used to cool the oil.
93.06 -> Compared to a 20 HorsePower 2.9L Ford T,
the Beetle had slightly more horsepower
98.82 -> but 3 times less engine size. Although
obviously the design was 20 years newer.
105.96 -> The valves were in the Cylinder head
while the Ford T had them in the Block.
111.84 -> Having the valves in the head significantly
increased the entry and exit of gases.
115.92 -> Especially when the engine rotates fast
and the time of each cycle is shorter.
120.9 -> The combustion chamber was shaped like an
inverted bathtub, with straight valves.
124.86 -> Wich were driven by adjustable rockers and rods.
132 -> The intake valves were in the center.
The exhaust valves were on the outside
135.78 -> and then all the exhaust pipes were joined
at the bottom by the exhaust manifold.
140.82 -> This valve configuration improved engine
temperature, as cool air enters thru the
145.08 -> middle, the part that is difficult to cool.
All engine parts like finned cylinders are
148.74 -> available loose so one can rebuild their engine
from scratch without going to the grinder.
154.8 -> As everyone knows Ferdinan Porsche was
the designer of this engine and he was
159.3 -> a fan of air cooled engines. His motto
was that air does not boil or freeze.
165.06 -> In short, the beetle was able to work in any
climate such as in the cold of Russia, where
169.68 -> the radiators break when the water freezes, and
in the desert of Africa, where water is scarce.
175.26 -> The beetle engine was installed in the
kubelwagen. The German army vehicle and
179.76 -> reached 50 thousand units manufactured.
This small off road vehicle was very
184.56 -> light and thanks to that, even though
it only had simple traction and a ZF
188.88 -> limited-slip differential. That is to say, it
was not a 4x4 like its jeep willys adversary,
194.58 -> the kubelwagen could travel over any terrain
and follow the panzers without problems.
199.98 -> Also, by not having a water radiator, the
engine was literally bulletproof. Which
204.9 -> increased reliability in battle.
The jeep willys was better,
208.56 -> but the kubelwagen was simplier.
The boxer design lowered the vehicle's
212.64 -> center of gravity and left room to
mount the entire fan system on top.
216.66 -> The boxer configuration was key to cool down
the cylinders evenly, because in an in-line 4,
222.48 -> it would leave the central area
of the engine poorly ventilated.
225.18 -> I take advantage of this part of the video to
ask you to leave your super-thanks that helps
230.1 -> me a lot, or if not a like. Also remember
to subscribe. We continue with the video.
236.52 -> This engine designed by Ferdinand Porsche was
later modified over the years and enlarged.
240.9 -> Its engine went from 985cc to 1131. And then,
for the year 1954 to 1192cc, with larger valves
251.1 -> and a new carburettor, producing 36 horsepower
and revving at almost 4 thousand revolutions.
259.5 -> The electrical system began
with 6 Volts, but by 1975,
263.16 -> all units were already manufactured with 12 Volts.
269.22 -> High voltage coil and distributor were
always used as we can see in this video.
275.46 -> Its firing order is 1-4-3-2.
From the beginning, it had automatic
282.72 -> spark advance. First using centrifugal system.
That means, every time the revolutions increased,
288.06 -> the distributor fired the spark sooner.
Simplifying driving and achieving more power.
294.78 -> Later, the vacuum system was added.
When the accelerator is depressed,
298.68 -> the intake manifold pressure rises and also moves
the distributor. With these 2 systems the beetle
304.44 -> already had a very advanced and efficient
ignition system. And above all. Automatic.
310.08 -> Feeding was by a single central
carburettor and later replaced
313.5 -> by 2 individual ones. Which increased the power.
316.62 -> Coming to the end of its manufacture,
electronic Fuel injection was installed.
321.3 -> The exhaust system was also improved,
and a double one was installed.
325.44 -> As the years went by, the cylinder
capacity continued to increase and reached
329.52 -> 1.6 liters or 97 cubic inches with 50 horses.
The gearbox was 4 with forward gears plus reverse.
336.78 -> The gears were helical. Over time, synchronizer
rings were installed, which improved the shifting.
343.26 -> 3-speed automatic transmission
versions were also produced.
347.1 -> In 1974, the Volkswagen beetle dethroned the
Ford T as the best-selling car in history with
353.58 -> 15 million units. And for 2003. The last
classic beetle would leave the factory
359.04 -> in Mexico with its 22 millionth unit.
Leaving a free track for the New Bettle
364.26 -> that would be manufactured until 2019
although with a water-cooled engine.
369 -> The reality is that although the engine
only had minor changes throughout the time,
372.72 -> and always maintaining its essence and
simplicity, the number of modifications
376.74 -> it underwent exceeds 2,000. There are engines
from 800cc to 1600. Different types of pistons
383.88 -> to vary the compression that started at 5.6
to one and rose to standard values for today.
389.52 -> It started on carburettor and finished
including electronic injection system.
393.78 -> It even had a catalyst to continue
complying with environmental regulations.
398.22 -> To be fair, it is the most
manufactured vehicle in history
402.54 -> since, although it is in position number 4,
its changes are minor compared to a Toyota
407.4 -> Corolla where only its name was kept.
The Volkswagen's air-cooled engine
412.08 -> designed by Ferdinand Porsche knew to be
a masterpiece of engineering and design.
416.94 -> Surviving for more than 65 years,
participating in war conflicts,
422.64 -> being taxi, or with the Kombi T1, which was used
in every way, as an ambulance or supporting low
430.38 -> budget and maintenance trips with the hippies.
Another body available was also the Thing. Which
436.44 -> copied the kubelwagen in many respects
and was available in civilian versions.
441.06 -> During the 1950s the Beetle
was also used as a tractor,
444.36 -> thanks to its rear-wheel drive and great off-road
capability. Not to mention its high reliability.
451.74 -> A very similar version of the engine was also
454.14 -> initially used in the special Porsche
test car and would leave its legacy
457.86 -> for future air-cooled 911 production.
Equipped with 6-cylinder boxer engines.
463.44 -> You can always support me by leaving a super
