+C A S Try this one for mind blowing on you tube HONDA 125 5 CYLINDER AT GOODWOOD FOS 2002 yes a 125 cc 5 cylinder 4 stroke with 4 vales per cylinder that revved to 23k rpm in the early 1960s then came the 250 six plus a 50cc twin And still the 2 strokes won !!!
John Brown - you must be dumb cause all of what you learn is just Put into a video which mean you Learn better with picture or visuals then reading LMFAO.
Oh from the way he worded it i thought he meant this teaches about cars n such better then his school does? but what you said is valid to, didn't think of it like that.
With todays technology and the availability of information, the learning process isn't why schools are useful anymore. It is a means to find who is capable of certain things. Credibility. And it is useful for getting children experience with social interactions. It's an archaic system of learning where the most beneficial affects are not the original intention, but those benefits keep it alive.
For some reason, even though I know thoroughly how every aspect of an engine works I still love watching these kind of videos. Watching engines work never stops being interesting to me.
YOU HAVE NO IDEA HOW HELPFUL THIS IS. I can't thank you enough. I've been looking EVERYWHERE for a video that explains how an engine works. This one is PERFECT. Super mega ultra props to you for making this so simple to follow. THANK YOU THANK YOU THANK YOU! =D -Darcie
+magicstix0r - I don't think that is the case Magic. The term ""Fossil fuel" is pretty inaccurate. We pump oil from well below where fossils are found. So calling it Dino oil is a misnomer. As time and science advances we learn more about things. An oil well that had ran dry in Texas back in 1942 (and was capped) was reopened recently and found to be full of oil again. Since the deepest anyone has drilled into the earth's crust has been a scant eight miles, we really don't know what is going on down there, we have theories but they could be meaningless. Since oil wells that were dry are now refilling some people have came up with some new theories. Some believe that an unknown geological process is taking place within the earth and that oil is a byproduct of that process, i.e., oil may very well be a renewable resource.
Awesome explanatory & demonstration video of learning the fundamentals of a gas powered engine. Thank you for posting this magnificent video for the average person or anyone who wants to know, learn or understand how gas powered engine works! :)
Human beings are extremely intelligent. Let them do something they enjoy doing and pay them a decent compensation, and people will come up with real solutions for real-world problems.
Yellow Submarine Remember. Each piece was conceived one at a time. This engine started much simpler. Piece by piece its efficiency was raised. Then to the point where you have the masterpieces we have today.
My automotive teacher is good at teaching but I can’t just learn from reading notes and automatically know what it does. This is a good video for people who learn better visually like me.
Understood so much from this video. I’ve known what VVT and TDC and IDC are from college but now I understood why they are important in and engine. Thank you!
The 2JZ engine was just the name of the twin turbo fitted to the Supra the actually engine was a performance crankshaft v6 a turbo adds compression thus making the explosion in the combustion chamber to be stronger.
LOL you're right. I get a notification about 4X a week with someone saying "not all Toyota engines..." Well this video was made in 2007 and was designed for dealers talking ONLY about current vehicles. Way before the FT-86 and WAY after they had any inline 6s in production. The Supra guys are the most annoying. Like I'd do training in 2007 for engines that had been discontinued in the early 90's (rolls eyes).
Although I already know how an engine works, I felt like watching this video because it seemed interesting and I must say, out of any video I've ever watched, this is by far the most educational, and easy to understand video. Really great work!
This is a very well explained video, even if many aspects are simplified (I wouldn't know) it's still helped me grasp the basic concept of how a typical engine functions. In short, thanks for the free education.
Funny how they refer to the "outdated inline 6s" in a poor taste, when the 2JZ was the best motor Toyota ever made. Guess this guy has never seen the 6 second Supras running an outdated inline 6
As of 2014 Toyota had sold 200,000,000 cars. There are maybe 10-20 "6 second Supras" in the whole world. Nobody gives a crap, it's a dated engine that nobody is ever going to resurrect. You Supra guys need to get over those things.
allegroracing I see where you stand when your only value in the quality of an engine is how many of them were sold. There's a reason nobody talks about any of these economy shitblocks that you praise, and you'll never see one at 1,000+ horsepower. Lets see any one of Toyota's other motors handling 35+ PSI of boost on stock internals. I'm not saying it needs to be resurrected, I just think its funny that you would leave negative annotations about it in the video, clearly knowing that you'd piss a lot of people off. I'm not a Supra guy either. I just respect a good engine. Grow the fuck up, it looks like you're at the very least in your 30s, time to start acting like it.
Griste I gotta wonder if he means " outdated" as far as toyota is concerned and not the rest of the world. My car is a 2012 Falcon F6 and it's using one of these " outdated" inline 6's to pretty much decimate everything it runs against. en.wikipedia.org/wiki/Ford_Barra_engineYeah its based on old tech but wouldnt " out dated" mean its no longer any good and somethign better has replaced it? I think " dated" would be mroe accurate. Not OUT dated.
The modern internal combustion engine is an incredibly complex machine, that is the result of perhaps over 100 years of innovation and evolution. The Engine is short for "Genius Machine". I went thru Mechanical Engineering school in college, and yet, no class or professor in the curriculum ever explained this machine so thoroughly.
Engine does not mean "genius machine", and whoever told you that is an idiot. The word engine literally means, "a machine with moving parts that converts power into motion." Read people. Open a book every once and a while.
+Viorel Matei Exactly. And that's why aftermarket "intake and exhaust" setups are so popular. The problem is, because modern cars are computer controlled, in order to really get a proper benefit out of changing the mechanics, you also have to change the electronics to do something with that extra air and fuel. It will only change slightly on it's own just by bolting stuff on and, frequently, that actually robs the engine of power because the ECU holds back because it doesn't detect the engine running "properly." And that's why turbos and superchargers add so much power...they are "cramming" air into the engine under high pressure and therefore a lot of fuel can also be burned in order to produce more power.
ECU'S can be remapped ! But all over my head now back the shed to play with needle levels and float height and get the points spot on with a dial gauge and a timing light !
Thank you so much for this video I'm trying to become a engine technician for Toyota this video has helped me understand a lot about there engines and makes me even more excited to work hard and learn!
When Heat panels that generate electricity envolves that can be taken off the list put friction is hard coz what can we put on our tires that wont brake or inside motors moving parts and can we make somehow more electricity out off moving parts of the car...
+BRBallin1 A couple of ways. 1. The other cylinders firing imparts energy to the crankshaft that keeps all the pistons moving even when they aren't being fired. 2. There's a heavy flywheel on the end of the crankshaft that keeps the crankshaft tending to want to spin.
+BRBallin1 Pretty much what allegroracing said above, except that I'd add: On any engine setup (4 cyl, V6, V8, etc), the ignition timing (frequency of sparks from the spark plugs) is setup so that each cylinder "fires" in a sequence, usually one after the other. So if No 1 cylinder fires on the power stroke, as it ascends on the exhaust stroke, No 2 cylinder is firing on _IT'S_ power stroke, then 3, then 4, and so on. Thus, at all times, the crankshaft is receiving jolts of energy from one or more pistons pushing down the connecting rods.
nicely put and has made me understand the engine better, now i need to learn about the other parts of a car more tutorials please!! this was interesting!!
I get what you're saying and I feel that way too about a lot of things regarding college... but I think college is just one small stretch on the long road to really knowing the deep shit about engines. This video is only scraping the surface and is more than most people would have initially known I'm guessing
In 2008 when this video was produced for Toyota dealer personnel, there was no non-V 6 or 8 cylinder engine in production by Toyota. The video is not a historical accounting of every engine Toyota ever made but a contemporary training piece that is only interested in the product line that was available in 2008.
Fantastic, insightful video. I found the ACIS and VVTI explanations very succinct, and I'm hyped to learn more details about them. Thank you so much for uploading this! :)
vvtL-i is the equivalent of vtec. however vvt-i is in the celica gt and the vvtL-i is in the gts. The 'L' stands for lift which is the crucial difference between vvt-i and vvtLi I had a celica gt and there was no "vtec" but my buddies gts had the kick after a certain rpm, just like vtec.

At which point does the liquid fuel become a gas? Is it liquid before it enters the combustion chamber or what? I can't picture a piston trying to compress liquid.
The fuel injectors spray the fuel as a mist into the combustion chamber. A sort of "average" air/fuel ratio is 14.7:1 so there's mostly air and a little fuel in each air/fuel charge. There is a condition called "hydraulic lock" which is where oil, fuel or water (if the car has been flooded) fills the combustion chamber. In that case, you are correct, the liquid is incompressible and the connecting rods will get bent (at a minimum) if the engine is attempted to be started.
Automotive engineer here. At 2:31 it says that higher compression ratio require higher octane fuel. First, it is not the combustion chamber and the cylinder that is build around fuel, but the other way around. A fuel with higher hydrocarbures links is more likely to combust on it's own because of it's more volatile nature (it stores way more energy, thus unstable) ergo it makes an alternative fuel beside gas. That being said, with a fuel that is volatile enough to combust on it's own (at high temperatures and pressure), engineers made an alternative internal combustion engine with more space, so the fuel can accumulate enough pressure and temperature during the compression phase, thus making higher compression ratio! Second, a fuel that is more likely to combust on it's own would have a high cetane number, not octane. An octane number is quite the opposite. Octane number represents the fuel's capacity to not combust on it's own. Usually cetane is associated with diesel and octane with gas! Have a nice day :D
Damn videos like this make you appreciate new engine technologies that oldheads love to tear apart; “filled with computers,” “can’t work on them yourself”
A lot of people still buy the BS that modern vehicles don't last as long as "simple" old ones but that's nonsense. WIth the much higher level of metalurgy and computer controlled machining, plus the fact the engines are computer controlled to run perfectly all the time under all reasonable conditions, vehicles have never been as reliable or long lasting. It's a fluke when you get a dud of a modern vehicle and it's usually a design flaw that causes it to be a dud.
Older cars were not more reliable, they were just easier to diagnose and repair yourself. I for one, do not miss the days were you had to make sure you brought spare points with you for long roadtrips, or retune your carb because you went up 2000 feet in elevation, or have to stop for a while to let your drum brakes cool down so they actually work again. Not to mention the absolute joy it is to start a carbureted engine in below freezing temperatures.
Just reading the description. How is this US market only technology? I have a VVTi engine in my Toyota Corolla, and I'm in New Zealand. Isn't this Japanese technology on a Global market? If it's US only market how does the whole world have it?
The video is written for US dealer personnel so specific systems and statements only relate to US market vehicles. You'll notice there's no mention of diesel...because Toyota doesn't sell any diesel engined vehicles in the U.S. Of course Toyota uses common technology all over the world but the specific combinations are often market specific. I get people saying "what about the U3TG engine they sell in Uraguay, that's a W 23" or something like that and got tired of it.
allegroracing My mum has a 2L turbo diesel Corolla. I just have a 1.8L VVTi. You need to get the 2L turbo diesel in the US, it's amazing up hill! It's weird though because the one mum has is European spec with the signal controls on the left not the right. Every time she drives my car the wipers are going at every intersection haha!
+Sundaram Periyasamy Because in order to convert potential energy into kinetic energy, the most energy-efficient yields are from burning stuff and that causes chemical reactions and releases compounds and chemicals which can never be 0. You can't "create" heat with 0 emissions. It's impossible.
He (annotations) said that engines with 6 cylinders and upwards were V shaped. That was our point. Also the annotations said "I don't care for the Supra:.
