The history of the internal combustion engine is long and kind of out there. So many different brilliant minds had their hands in the mix and it’s not really set in stone as to who invented it.

Engine: The History of a Concept, From 14th-Century Poetry to Google:
“Engines may be a relatively recent invention, but "engine" the word has been around for quite some time."
Who Invented The Steam Engine?:
“In a world propelled by combustion engines, gas turbines and nuclear reactors, the steam engine may seem like a relic of the past. But without this game-changing invention, the modern world would be a much different place."
“Lenoir’s engine was a converted double-acting steam engine with slide valves to admit the air-fuel mixture and to discharge exhaust products."
History Of The Starter Motor:
"Although we take starter motors for granted today, the so-called “self-starter” wasn’t even conceived of until several decades after the arrival of the horseless carriage."
Two-Cycle And Four-Cycle Engines:
“A basic design feature that aids in small engine identification is the number of piston strokes required to complete one operating (power) cycle."
When Old Things Turn Into New Again:
“While combining gasoline and electric motors in a car seems like a miracle of automotive wizardry of the 21st century, the origins of hybrid technology actually date to the end of the 19th."
What Is The History Of Hybrid Cars?:
“Generally speaking, a hybrid car is any car that uses more than one fuel source. Nowadays, however, we mainly use the term to describe cars that combine a gas-fueled internal combustion engine with a battery-driven electric motor."
Aug. 12, 1888: Road Trip! Berta Takes The Benz:
“Berta Benz, wife of inventor Karl Benz, takes her husband’s car on the first documented road trip in an automobile."

Lenoir and Clerk were the main pioneers of the two-cycle systems...De Rocha invented the four-cycle method, Christian Reitman built it....and an Italian guy that invented the stethoscope built the first 4 wheel, reciprocating engine driven car....The kindergarten version is boring. Dugald Clerk (Clark) was a superman.
That's why I laugh when people hail guys like Steve Jobs as "world changers".....Steve Jobs gave the world time waster SHIT that makes kids in their 20's think they are "modern".........men like RUDOLF DIESEL CHANGED THE WORLD. Compare guys like Edison, Tesla and Diesel to geeks like Gates and Jobs......what a joke.Rudolf Christian Karl Diesel (March 18, 1858 – September 29, 1913) was a German inventor and mechanical engineer, famous for the invention of the diesel engine. Diesel was the subject of the 1942 film Diesel. The diesel engine (also known as a compression-ignition engine) is an internal combustion engine that uses the heat of compression to initiate ignition and burn the fuel that has been injected into the combustion chamber. This contrasts with spark-ignition engines such as a petrol engine (gasoline engine) or gas engine (using a gaseous fuel as opposed to gasoline), which use a spark plug to ignite an air-fuel mixture. The diesel engine has the highest thermal efficiency of any standard internal or external combustion engine due to its very high compression ratio and inherent lean burn which enables heat dissipation by the excess air. A small efficiency loss is also avoided compared to two-stroke non-direct-injection gasoline engines since unburnt fuel is not present at valve overlap and therefore no fuel goes directly from the intake/injection to the exhaust. Low-speed diesel engines (as used in ships and other applications where overall engine weight is relatively unimportant) can have a thermal efficiency that exceeds 50%.
Otto came up with the constant volume heat cycle named the Otto cycle after him. Karl Benz came up with the diesel, or constant pressure cycle. The ICE mechanism was derived directly from the steam engine.
I'm pretty sure its pronounced Christiaan Huygens~>(Hoyg-ins). That's how a team at N.A.S.A. says it when referring to a probe they have (or had). Come on, if that's how N.A.S.A. says it then it's gotta be correct! Right??.LOL. Anyways, love all the work the team and you do as well as your other channels. Keep up the good work.
explain hp vs torque what they have in common and what's different shirt version and in depth allot have trouble explaining this and I love cars know allot about them but still don't quite understand it
What pleases me is that, as a student studying engineering, there is so much work going on in this field it's extraordinary. Sadly online media companies don't seem to care as it's not 'save the worldy' enough or 'electronic / techy' enough for the headlines, but in the last couple of years there have been some amazing developments in engine technology, in the automotive sector alone.
One of the most impressive being Infiniti's variable compression ratio engine, but also the likes of Toyota's new line of engines which can allegedly touch 40% - 41% BTE in a spark ignition car engine. That's phenomenal. Then there are interesting concepts like Christian von Koenigsegg's Freevalve engine (and indeed company). As well of course as alternative engine architectures like the opposed piston engines Achates Power are bringing back to the engine shop (the Commer TS3 is one of my all time favourite engines).
Long may the internal combustion engine be improved. One of the most amazing machines on earth that people sadly often belittle, or take for granted. Without it we'd be screwed. Great video :)
Thermodynamic blasphemy! Discussion of the internal combustion engine without any mention of Carnot!?!?!? Repent to the gods of thermodynamics. Although you covered Otto, so, he made a cycle, that's cool. Carnot invented the cycle against which all other cycles are compared.
I took a road trip last year just to kind of get away from everything. I started in Fort Worth Texas and ended up in Albuquerque, NM. I went and saw all the places around there that they filmed Breaking Bad, climbed the Sandia mountains, and a whole bunch of other stuff that would take to long to list here. I did temp work to support my self and when I didn't have money for food I ate from the wild fruit trees. I slept under the stars and watched the sun rise over the mountains every day. It was one of the most amazing experiences of my life. And the whole time I was there I lived in a 99 Dodge Durango.
I had to make a school presentation about hydrogen engines. From my research i remember something from 18th or 19th century, which was some type of plan for preservation and responsible usage of our resources from scientists , philosophers, etc. But of course it got ignored. Kinda keeps you thinking, doesnt it?
natural gas I.C.E. is this not right beside EX.C. as i under stood it, natural gas did not need a carburetor. natural gas was not abundant, and needed tanks. and to get passed the ka-boom of contained gasses. natural gas got left on the side of the road. for the steam engine. yet some were i learned this was the first I.C.E.
Any fuel, gaseous or not, requires a carburetor or injection... it needs some way to meter the fuel in proportion to the air. Even diesels require a minimum/maximum metering threshold, albeit at a much greater range.
Natural gas isn't stored with atmospheric air. The pressure of the vessel alone, could cause it to ignite. The first liquid fuel internal combustion engines ran off lantern oil (not to be confused with lamp oil)... very similar to the same Coleman lantern fuel used by hobby engine builders today. Gasoline in those days was a volatile and inconsistent fuel. Ignition resistance could be notoriously low, fuel would sometimes spoil quickly. If you count hydrogen gas as a natural gas, it was invented first... however, lantern fuel engines were the first true ICE hydrocarbon fuel engines. Natural gas did find favor in colder climates with availability, however... especially in emergency response equipment and vehicles, for it's stability and cold start dependability. The junkyards of the Rocky Mountain region are loaded with old tow trucks, heavy equipment (mostly power shovels), police cars, and even some ambulances and fire trucks with pressure vessel tanks.
I would argue that all technology was created in an iterative way. The sad part is cars have evolved but compared to other technology ICE's, that power the cars are quiet ancient. There has not been a fundamental change in power generation for personal transport in over a century. Could you imagine other segments of technology evolving so slowly? Computers would still have vacuum tubes and phone wires. My verdict the ICE has a rich history because for the latter half of a century it should have been history.
Felix Wankel, and the Wankel Rotary engine. One of the few to make his own ICE that was not based off traditional engine designs. And the only one not made from traditional designs to actually see service.
Another note, Ferdinand Porsche designed a version of the Nazi Tiger tank with a hybrid diesel electric drive system. It failed to perform though suffering from malfunctions and breakdowns when competing for the contract.
my favorite was camping in ruidoso new mexico. we were going through the mountains, when the car started going whom wom wom womwomwomwomwom boom! shreeeeeeeeek. the rear passenger tire fell off the van. i was in the back watching the 4th of july (showers of sparks). we stopped right there on the highway and camped for several days while the van was in the shop. there was an indian reservation, and they were having a pow-wow. it was the most prehistoric reality show i ever saw. they were real desert people. the bathroom, i couldnt even go all the way in because the smell of urine and feces was so strong. I looked inside the public outhouse, just like any in a national park, except the floor was under several inches of pee, and there was a big pile of shit right in the middle of the 15×15 foot restroom. I shit you not. they had to walk through the pee to poop on the pile. there wasnt even toilet paper. I thought yep thats pretty savage. I gotta find somewhere else to go potty like a civilized human being.
Why haven't anyone invented perpetual motion gravity engines, cars, airplanes, and trains, etc like earth, and planets rotate, and fly by our sun gravity, and the sun fly by the Milky Way galaxy gravity, (galaxies fly by what gravity?, etc)? you don't need gas, oil, food, and electricity, etc for gravity motion? gravity may be powered by bacteria, fish, animal, creature, and human souls???!!! Are we in an extremely evil universe that is so beautiful and wonderful from the outside???!!!
This subject would have been an ideal topic for the now discontinued TV series "Connections".
Just another point. My first car, a 1959 Triumph TR-3, still had a provision for a hand crank, should the battery go down. This was in 1960.
In May 2015 took a trip from PA all the way out to Rushmore and stopped in Kansas City. Really beautiful country out there. I would recommend the badlands to anyone who wants a scenic place to travel to.
+Special EDy i wish it was that simple, but its not. yes the reaction of hydrocarbons poduce H2O, CO2, and CO. The problem is that there are other things in the gas. Im no expert in what comes out of the ground but probably stuff that isnt good like sulphur, heavy metals, carcinogens.
Also the way you used pollution is correct as in net amount of carbon on earth has more or less stayed the same, but its a matter of releasing more CO2 than the plants can handle as they consume only so much so fast. Then tack on the deforestation as we significantly reduces the overall ability to remove CO2. There is probably more factors that contribute to the increased CO2 levels in the atmosphere. A better use of "no pollution" would be all our gasoline we obtain comes from carbon sources on the surface causing no net change in carbon on the surface and the atmosphere of earth compared to where levels are now.
Because the ICE is still vastly superior to electric cars. The energy density is higher, gasoline cars can go farther and refuel quickly. They are cheaper and last longer than the equivalent amount of batteries. The best solution until battery technology improves is to focus on finding ways to artificially create gasoline, like ethanol. We aren't polluting when we burn gasoline, we are just releasing carbon dioxide and water that plants consumed back into the atmosphere. With current technology, electric cars have a far greater negative impact on the environment.
I'm fully aware it's a podcast and I never said they should change it, nor I have said I can't understand anything :-) Yet, if you make a podcast that is s'posed to teach you about stuff from scratch, stuff that is very practical, mechanical and so on, words alone are indeed a poor medium to share the knowledge, especially for non-native English speakers. Even academic books on engines have some pictures and schematics as I've just had one on my desk not so long ago. Pictures ARE worth a thousand words so don't be such an elitist, Walter White. I've just completed a course in astrophysics with almost no pictures included and I'm fine, but it's mostly an abstract subject full of thought experiments, so words are ok. This is quite the opposite. And that's making it way harder to comprehend because you can't leave it to your imagination. You have to know precisely what is what and where in the engine - which defeats the purpose of the podcast a little bit, since you're here to learn about it in the first place (or so I though at least given the title of the first video in the series).
Go fuck your self, it's not possible for him to perfectly pronounce every persons name in the entire world. Unless you think that Mr. Huygens name is the only one every person in the world should know how to perfectly pronounce?
+Hamid Shokri Lol, Homer, my friend: Get over it. Speaking as a Dutch person, we just have to accept that the whole world can't really handle Dutch pronunciations.
Stop being offended over mispronounced names from impossible languages nobody in the world knows.
110 or so there and back, most of it was on motorway restricted to 50 mph for road widening enforced with average speed cameras. the rest of the journey was between 30 and 60 mph navigating very unfamiliar country, small villages, twisting back roads and the roundabout central that is Aylesbury with an hour for breaks
please talk more about electric cars not only hybrid cars....electric cars are more envirom,ent friendly...hydrogen cars are also bad because you would have to use gas stations again for hydrogen...so it would be more costly...also you can repair a electric car more easyly than an hybrid or even an hydrogen car
+Shogun of Japan to get hydrogen you would need even more electricity...
hydrogen does not occour on our planet in natural form
the cheapest way would be electrolysis which splits water into 2 hydrogen atoms and one oxygen atom
so it would actually be cheaper to use electric cars...
hydrogen cars use electric motors as well
+Bart Simpson well...an elecric car uses mostly the same components as a hydrogen car...except the hydrogen cell...have you ever worked with an hydrogen cell?
i bet you worked with batterys did you?
also you would have to buy hydrogen from a "gas" station...so they can make the prices...electricity is already delivvered to your house or am i wrong?
