Thank you for your valuable comments. The animation shown here is simply for an illustrative purpose. The oil travel shown in this video is mainly to allow viewers to understand how the lubrication process takes place. Otherwise, it is not necessary for oil to first enter through the crankshaft, and then to the camshaft.
Once the oil is pumped from the sump does the process keep repeating itself? Or once the pump has pumped the oil will keep rotating until the car is switched off
This is a great explainer video! My current car is burning oil, so this was helpful for me to understand how the recall issue could play a role. I hope the manufacturer will honor the warranty and replace the engine without protest.
@Israel V you got to be in the shop seeing real time repairs that's how you gain knowledge there's things that theory can't explain like parts not working because of rust or internal failure from too much heat
The amount of oil available within the engine oil sump is fixed. Also, as you can see in the video, the oil is not allowed to enter into the combustion chamber using the piston rings. In case when the piston rings break, oil and fuel gets mixed together, which results in white exhaust smoke.
please add explanation sound also cause we have ability to learn from both hearing and seeing also, i have watch all your video and i feel great after watching your film
Thank you very much for your feedback and appreciation. That encouraged us to create more informative videos that can really help automobile community. Don't forget to share this videos with your friends and spread knowledge !!
Very nice except that I've never seen oil jets used for the valve train and never seen them on a gas motor under the piston. Diesels use them as cooling jets to keep from melting the top of the piston.
You haven't seen them because they don't exist. Oil squirters exist on SOME gas motors for the same reason you have seen them on diesels. Cooling. Case in point the non turbo 2JZ's don't have oil squirters and the turbo ones do. Same for the valve train. They don't exist.
being driven by the engine it means the oil pump delivers more pressure at higher engine rpm. That pressure is controlled throughout the lubrication circuit by that bypass valve that u see mounted between the oil pump and oil filter. it has a simple spring calibrated to let the valve open at a certain force that is applied to it by the oil pressure. that pressure var
Amazing video.Understood clearly,even though without explanation in the video;the way they shown video with words is awesome.Please upload like this videos related to automobile,especially upload the videos of electric and hybrid vehicles.
1) No, the crank should not be touching the oil. This would cause the oil to be whipped around and mixed with air, "foaming". This can lead to a low oil situation or air in the lubrication system. It would also cause drag on the crank, leading to power and fuel economy loss. 2) Of course? I dont think i'm understanding your question. If you dont change the filter it will get clogged and enter a bypass state where no filtration will take place but still allow the dirty oil to circulate.
when I see this video, it reminds me of my Automotive facilitator Mr Jonathan Mklama. He taught me everything about the whole thing and how it works. #thumbs up
damn I kinda wished RU-vid existed 15 years ago when I was in high school. Shit is more interesting than reading books or watching old as VHS tapes from the 70s in class lol.
Would be cool if there was a secondary electric pump that would prime the engine when the door is unlocked, similar to how the fuel pump kicks on to raise pressure on some models.
That’s why you should never rev the the cold started engine it’s because the oil takes 3 mins to recirculate inside the engine. If you rev it right after the engine started, it might cause wear between the moving metal parts since the oil doesn’t have much time to circulate and lubricate the metal contacts together.
nice video 2 doubts 1) dosent the crankshafts always remains half inserted in oil and 2) do we not need to change the filter, since lubricating system is used constanly when car runs, the oil does get dirty...... thanks in advance n keep uploading love your videos
not all pumps are belt driven, some engines have the pump in the oil pan being gear driven by the crankshaft, and also the oil system doesn't need sprayers on the cylinders since the oil is splashing around
Pro-tip: it is called an OIL SPOUT or OIL SPRAYER or OIL SPRAYING NOZZLE or most commonly an OIL SQUIRT/ING (no not Cytherea, you dirty boy! ) . A 'sprout" is something related to a plant... your know, the green stuff that grows outside of the garage. That's generally speaking, there might be some tweaked-out loonies among the garage dwellers who'll go all sadomasochistic on their favorite orchids and keep some in their garage abode.
Thats why its very important to have the right oil for youre car and to change the oil required on the manufacturers specification if not dealt with the cars performance will eventually go from good to shit
Very nice,I am still confused about ht main bearing . I know there are hole in them, but how the oil pass through? In the video i saw some tubes, are they connected to each other ?
where is the oil temperature sensor located ? why only pressure is measured. Temp should also be measured to avoid overheating. You can include it as an update in next video
