I own a 2CV Special, model 1986. Works like a clock, goes everywhere. Simple, «rustique», 6 liters/100km, easy to maintain, but be careful with the rust. Not only the engine, but everything is simple and basic on this car. The dashboard is so simple! It is my only car, so it drives almost every day, and every year I make a quite long trip to visit friends all around France. Hope to keep it for a long time.
6:21 This is factually false.
Heating the intake air will lower the air density, and thus, causing the engine to produce less power.
This is why some modern gas cars use intercoolers, to cool the intake air. Making the air more dense, so more of it can flow into the combustion chamber. And create more power.
Thx for the correction bro 🙏🙏
agreed, but it's a common technique to use on carburated cars so ends up a net benefit to efficiency. my dad's 1989 nissan sunny used it. i guess its because carbs like to be tuned to operate at a consistent temperature. there's also the danger of carbs icing up, mainly happens in aircraft.
Warming the intake air flow only helps the engine warm up. Then warming the air hinders optimum engine performance. In the VW engine, there is a thermostat which closes the louvers in the fan shroud on a cold engine so it can warm up to operating temperature. Then the thermostat opens the louvers to give maximum air flow and optimum engine performance. Shade tree mechanics that removed the thermostat and louvers to "increase air flow" didn't know what they were doing.
The 2CV is trully brilliant. I drove one 10k miles through UK and Europe and got 55 miles to the gallon at 60mph fully loaded with 3 people and camping gear and all with 600 cc flat twin motor. They have a fantastic heater for cold clinates and a roll back roof for summer, i only wish i could have brought mine homewith me
Thanks for the information dude.
About half of everything told here is incorrect. Please, if you don't know what you are talking about don't make youtube videos explaining engine technology to people.
On subject: The comparison between these engines is pointless because apart from they both being aircooled boxers they are very different. The four cilinder VW engine definitely is more advanced, better balanced, and has more torque and power. And though the VW engine is relatively light, the Citroen engine is much lighter. This was important because of the low vehicle weight of the 2CV. Exept for the breaker points maintenance the Citroen engine was easier to work o.
Both these engines have proven to be very reliable (probably more so than most modern engines).
Definitely got some things wrong but still a cool video however I think the greatest thing about Citroen has always been their suspension
The compressor section is spinning the wrong way, but you have the turbine section going the correct way, but the turbine is missing the first stage nozzles. If you go through this much trouble to make an animation shouldn't you at the very least have it vetted by someone to ensure you haven't made an obvious error?

If you heat air it becomes les dance. Not more. In fact the heat pipe connection from the exhost to the carburator was equipped with a wax operated port. This avoided the hot air to go thru the carburator when the engine was hot and only was used for cold starts. This was not working well and was not present on latest versions.
I have had a 375 CC model "Fourgonette" from '57 and a 2cv6 from '82. The fourgonette had a 12hp version of the engine. I did upgrade the Fourgonette with a 602cc engine from a Citroen Dyane with the 4 speed gearbox and all the breaking system. In the 2cv6 I did replace the 602cc engine with a 650cc engine from a Citroen LN. This had a Aluminium engine. The 2cv had Aluminium heads but cast iron cylinders.
Those engines had not only closed rods but also no head gasket. In stead it was a conical fitting.
The oil was mainly used for cooling the engine. That is wy there was such a big oil cooler. That oil cools was holding 60% of the oil when the engine was running. Making it a partial dry sump.
There was a 4 cylinder version of this engine. It started in the Amy 8 super (1050cc) that was a "luxius" derivative from the 2cv. Then it found its way in the Citroen GS (1100cc, 1220cc and 1300cc) and the Citroen Axle (1100cc).
The 2 cylinder version of 65Occ was found in the Citroen LN and the Citroen Visa whitch had also 4 cylinder engines but not boxer.
I think of the 2CV with its 600cc flat twin as half a Beetle engine:-)
think of it as twice of a beetle engine
The Citroen has a 4 speed transmission.
I really like Citroën 2CV and came close to buying one in 1975 but it was more expensive than a Fiat 127 eg with a 4 cylinder 900cc engine or similar cars, so it was overpriced which was far from its original character , i.e. a frugal and particularly cheap car.
The Citroen 2CV has a unique style but does not meet modern safety needs. The engine is very interesting but one can hardly say that it is the best ever made. This iconic car can take you everywhere but with enough noise and moderate speed. Although its "philosophy" - austerity but with reliability - is admirable, one has to overlook quite a few things to have it as a unique car.
many errors concerning the 2cv...the all first 2cv,all aluminium alloy body, from 1939 had a water cooled engine, 2cyl 325cc and 8hp, 250 2cv from this model was built but never sale because of the war. In 1949 was the all new designed 2cv (all steel body) launch with the known air cooled 375cc engine of 9hp, aluminium block with cast steel cylinder and aluminium heads, but was many evolutions from the engine: next was 425cc/12hp, later 435cc/24hp, and the last and strongest was the 602cc/29hp...ALL 2cv had a 4 speed gearbox (presented to Pierre Boulanger as 3 speed+1 overdrive)
Dont forget Tatra!!!!
False information at 5:14 which claims that the less than ideal placement of the spark plug gap (for #3 cylinder) can result in overheating. This is a nonsense statement. Actually in earlier engine models the fan shroud contained the oil cooler in the fan shroud in a place closest to the #3 cylinder. As a result the #3 cylinder did not receive the cooler air that the other cylinders received and tended to run hotter and wear out quicker. In later models (with dual port intake manifold) the oil cooler was placed outside the fan shroud allowing all the cylinders to cool evenly.
Oil pupm...
Rolls Royce made 6 cylinder flat, air cooled engine, seen at Duxford, but cannot find evidence of it.! Has any one else seen it.?
This was an airplane engine and not a car engine
@@DanielvanKATWIJK Thank you Daniel. I didn't realise that not everyone was aware that the VW, engine and the 2 cylinder 2 CV, are used in Home-built aircraft. As in the U.S. and Aus. Which reminded me of the Rolls Royce 6 cylinder, seen, but never heard of again. Was just wondering if anyone knows what happened to it.? Sorry.!

Hello,
yes effectively the VW engine was used in aircrafts all over the world, with both air and liquid cooled versions. Some freinds in Australia did put a liquid version in their T3 Komby 4x4 van.
The 2cylinder Citroen was only spartialy used in aircrafts. The 4 cylinder a bit more. Peugeot used them also in motorcycles.
