Fuel Injection System: Comparing How TBI, PFI or MPFI, GDI, Dual Injection Works?

[@alexpaulino7]

So far the best fuel injection explanation I have found thank you !!

[@damindasampath5947]

First comment from me. This video was most available to me. Good job. Thank you...

[@TheEngineersPost]

Most welcome 😊

[@UsrYtb-zx3ru]

I finally found a great video. I appreciate how it transitions from old to new technology. This gradual progression helps with understanding by introducing complexity step-by-step, explaining the issues they overcame or improvements made. The complexity of the topic was also very well presented.

Sounds like an AI voice so.. probably someone writing aluminium normally, but using an American voice for voiceover

howzit! 0:12 I was really surprised to see the Russian carburetor PeCar K-151 because in my early days, I fixed them a lot. Thanks a bunch!

[@bobjackson4287]

Looking at GDI all i hear is some old mechanic saying "Endless money pit"

[@misty-i2q]

Carbon buildup on the valves

[@ianpolo5673]

Hahaha. It's true because it is a flaw but some makers still use it without port injectors.

[@tsriftsal3581]

Not so if venting to atmosphere was permitted. Rolling non-smoke!

[@justinbelk89]

I have a 2023 Kia Sportage X-Pro with a 2.5L dual injection engine. This video explains what I was looking for, when does each kick in. Great video. And great engine too.

[@1212CRMD]

Thank you for such a neat and thorough explanation!!

[@MrSupernova111]

Beautiful explanation! thanks!

[@memeAlexcheramie]

6:56 actually, before I engine-swapped for a bigger engine, my 1984 Camaro had a carburetor that acted like fuel injection, but also acted like a carburetor at the same time. It had parts inside of it that regulated fuel-air mixture controlled by the ECM.

[@tsriftsal3581]

Ah, that was a crazy system

[@tsriftsal3581]

Forgot to add, crossfire injection

[@gregorymalchuk272]

Was it an electronic Quadrajet carburetor or a throttle body fuel injection setup?

I have a '64 Merc with a 390CID, I study a lot bout injector systems but decided to stick with old school far easier to maintain, currently running a Holley 650 double pumper with manual secondaries and choke, runs great, quick response sure you have to let her warm up a bit in cold weather, but so much simpler than these new fangled things

At 15:27 - Petrol/gas fuel burns with a flame front, it does not explode. Diesel, on the other hand does explode, these engines are referred to as detonation engines.

Thanks for giving good knowledge of injection system of vehicle please make video on fiat quadra jet engine injection system.

[@schrodinger3467]

GDI is preferred by car manufacturers as part of planned obsolescence...unless you periodically maintain your vehicle--but that adds to greater co$t as well for parts and labor.

[@JD-yx7be]

most moved to dual injection now

[@getthewin1046]

Well done

[@sannissansanjuan5074]

Back in the 80s European cars had Fuel Injection E-CIS Called K-Jetronic or CIS or Constant injection System, it wasn't a Sequential system, outdated by 1985 Where Some Top Line American and top line Japanese Cars used a Timed Sequential Port Fuel Injection System

[@piconano]

Do you have a video that explains how the old mechanical fuel injectors in diesel engines work?

[@keyaanadeeb]

Old mechanical diesel injectors work in a similar manner, instead of a electromagnetic coil, you had a camshaft press the injector, spraying fuel, more like a bottle of glass cleaner, you pull the trigger, a fine mist of it comes out.

[@AquaMarine1000]

​@Keyaan Adeeb The old Detroit Diesel injection system worked like this. Then came the rail pump and then the Bosch VE pump designed for high-speed diesel engines.

[@karanmadan1048]

As said too many components,parts & their requirements,got a solution as follow:- 1)Either one or not more than two pistons engine. 2)Power problems can be achieved by making a choice for the size of the piston. 3) Position of engine fitment in car to get body balance ratio for getting the best performance from engine. 4)Research which type gives three qualities,reliability, performance & fuel consumption to the standard.

[@bacphamnhu2363]

Does the system have a fuel return line to the tank? in Dual Injection System

[@samiuddin6696]

Knowledgeable presentation. Thanks for preparing this good piece of knowledge

[@isleofmann1088]

Will the life of the injectors for the GDI sytem be shortened since it's directly in the firing sequence in the combustion chamber?

[@dragospahontu]

Not really, they're made to last.

[@Mr_Glenn]

​@@dragospahontu The negative is that direct injection does not clean the intake manifold.

[@sagnbaby]

@@Mr_Glenn Not the intake manifold, the intake valve

[@LeoNickle]

Wouldn't simultaneous fuel injection be worse for fuel economy and emissions than sequential and batch because you're getting fuel delivery on strokes that aren't the intake stroke?

[@lancecorey6582]

The batch injection would have the same problem. Only one cylinder is doing an intake stroke. Why would anyone inject fuel into more than one port at a time since the wiring and electronic control is not difficult?

[@schrodinger3467]

Because that's what the huge gas corporations want everyone to think. More gas purcha$e from them..

[@germangallardo]

I am assuming it changes torque or hp depending on cc of the cilinder and sequence. Maybe batch would improve torque, while sequential focuses on horse power , ?

[@MrSupernova111]

What do you mean by simultaneous? The dual injection system operates at different rpms.

[@ohenenorb]

There's hardly an engine that works solely on simultaneous injection through all rpm. I have a car with Nissan engine QG18DE. It starts with simultaneous injection when the engine is cold, for about 20 seconds, and switches to sequential injection when engine rpm is above idling or engine temperature being communicated to the ECU shows the engine is adequately warm. So, simultaneous injection is for cold starting, then as the coolant temperature tells the ECU that there is a rise in engine temperature, the ECU switches fuel delivery to sequential injection.

[@BehailuBiruk]

Rely rely tank you

[@markdavis8888]

You missed the Ducted Fuel Injection, which is soon to change diesel engines.

[@akhildev8788]

Out of these types of injectors..which one is widely using now days in SI engine and CI engine??

[@rutukedarbhagwat1746]

CI uses spray guided Direct injection and SI engine use either sequential multi point or wall guided Direct injection

[@hakim.mkacher]

How could the simultaneous be better than sequential??

[@chadwickreno8499]

What about mechanical injection?

[@didodimitrov27]

Which cars use dual injection system?

[@HarrysonSalwani]

[@gpromburgh]

There are a few rather big mistakes in this video that should be addressed but its very wel Made. Better than I could do if being honest. But as a whole I don't think this video is done it needs corrections made

[@felipefalcon4811]

2:48 How can the fuel pressure regulator increase the pressure by alowing more flow?? if its after the rail it should restrain the flow so there will be more pressure inside the rail...

[@nagnathdeshmukh3257]

Pressure regulator increase the pressure by allowing more flow from pump and restraint after rail.

[@anybodynobody1827]

could you do a video covering various tunes? what tuning actually is? octane tunes? thanks!

[@xthomasbhx]

1:22 "a loo min ee um"

[@tsriftsal3581]

Not sure why but it is. When will ai demand pay for work and copyright? Doesn't seem fair that the work for free.

[@tsriftsal3581]

Ok so the efficiency is a humans fringe group demand of some sort of nebulous "protect the environment" factor that is and has been easily gamed. No one is monitoring the waste of such compliance. Still fun choosing 30 mpg or 16 mpg while driving and not caring about tossing the car to the junk pile prematurely without a care because someone more "caring" has made that decision for me and I'm guilty free. I'm pickle Rick!

[@redpilled7209]

GDI = God Damn It

[@abdulbabadiya4724]

[@MrSttlesks]

Gasoline Direct Injection

[@ecrush5080]

Sorry, but how simultaneous MPI system reduces fuel cons, more efficient etc... even when compared to sequential MPI ? anyone ?

[@viniciussurkamp6633]

Direct Injection is, necessarily, multipoint, as it requires individual injectors for each cylinder.

[@soheilpakgohar6630]

too much adds but tnx

[@karanmadan1048]

And some decided to get rid of complexity and try out everything working on electricity.

[@tsriftsal3581]

"save fuel" at what cost to you? $300 every 7 years vs $2000 every 5 years to maintain?

[@JD-yx7be]

dual injection is very reliable and gives not just efficiency but extra power. a NA 4 cylinder today is more powerful than a small block v8 of the 80s

[@adigerlaprasad5348]

💯👌🙏🙏🙏🇮🇳

[@Hamzakhan-mn7th]

your speed is high. please speak at adequate speed.

[@tsriftsal3581]

Want to help teh erff? Stop continuing to fuel after the click at the pump. You're just damaging you charcoal canister prematurely. Who's tracking waste emission charcoal vapor canister disposal? This is dumb buuuuuut. Love the choice we are permitted to have for now.

[@geimfarinn]

Another good video ruined by ridiculous AI commentary. Why don't people speak anymore?

[@SteppingR]

direct inj. was bigest BS for normal street cars, port is the best....about how much can drive a street car in high rpm , daily ? .....5% ? with a young stupid petrol head 10% ?

[@JD-yx7be]

it also allows for smaller displacement engines even reduce cylinders for the same power output. A dual injection NA 4 cylinder will have about the same power as a v6 with just port injection. One less head gasket, two less camshafts, 8 less valves.

[@Jamarkus_Delvonte]

I normally downvotw videos with AI generated voices. Well this is no exception. Down voted.

[@bestofthebest3821]

in the video in GDI the fuel is inject3d during intake, and the guy says its during compr3sion... whats right???
