@Mr6535 its actually the alternator that uses electromagnetics to recharge the battery which only works while the engine is already running. Hence why the battery can die if you leave the lights on in your car with the engine off but NOT when its running.
what happens if the fuel/air mixture explodes before the crankshaft is fuly over ? will the engine stall and kick backwards? (someone help me) – i’m making an engine and i am worried this may happen – what makes the mixture certain to explode at the very top of the stroke?
@mrhondacivicsi It’s a spontaneous combustion that deals with compressed air. When it is compressed it gains power causing electricity to happen. That sparks. It does that probably 200-400 times per minute.
@mrhondacivicsi ok theres a crank shaft thatss connected to pistons tthe back of the crank is connected to a flywheels and a clutch, the starter is geared with the flywheel so when u start the starter it turns the crank thus moving the pistons up and down which then causes the vavles to open being Air, fuel, and a exhaust so fuel goes boom on first ignition and then its a chain reaction on all the cylinders.
@CillBinton The flywheel whill store part of the energy produced in the combustion stroke. And that energy is used to compress the air in the compression stroke.
1 cilinder engines will need bigger flywheel compared to multiple cilinder engines.
@CillBinton the battery powers the starter motor which turns over the engine and gets it to compress and firewhich will contiue on its own so the starter motor disengages, and to charge the battery the alternator is spun by the engine which generates electricity
PETROL Engines require the Fuel to be injected into the Air intake stroke where the mixture of Fuel/Air is then compressed and ignited by a Spark Plug.
DIESEL Engines only inject the fuel AFTER the Air has been sucked in and compressed, as Diesel Fuel will ignite (combust) spontaneously when introduced to the hot compressed air. Spark Plugs are not required in Diesel Engines for this “spontaneous combustion” reason.
Good enough video as it shows the Diesel Fuel being injected after compression
@CillBinton it comes from other pistons, when 1 piston moves down it pushes another one up, and at the very start to get the crank shaft moving there is a started motor, big electirc motor powered by the car battery. the battery is always recharged when the engine is running
@mrhondacivicsi a diesel engine, unlike a gas engine, using a spark plug to ignite the mix, a diesel uses pressure, and so diesel engines are a fairly precise engine for sure, because at the very top of its stroke, it needs to have enough psi, like 400psi or something, maybe more, to make the diesel ignite, and so on. . . . a 4 stroke engine can get pre-detonation, which is harmful to a engine, because it makes it want to go backwards in a forward motion
@TrancinDaylee oh! roger that. thank you!
@hydrogenix
thats the diesel fuel being sprayed directly into cylinder. Most gasoline engines now are also direct injection.
WaveOutGetSelectControl. . . FAIL
How much air pressure is needed in the compressed air line that is used for the fuel injection?
Animation shows something similar to a spark on the top. . . and there is no sparks. . . :/

@DarkMetaRidley thanks!
@acerip574 Petrol engine has spark plugs to ignite the fuel whereas a diesel doesnt. . . . thats the only one i know
P = nRT/V

@DarkMetaRidley the flywheel helps with this process as well.
@DarkMetaRidley what is the difference between this and a petrol engine?

@CillBinton the battery? WTF
great animation for learning very easy

@DarkMetaRidley
Number of pistons varies and the battery is used as accumulator for circuitry as well.
diesels look good, but smell awful. . . eww
0:10 lol

diesel engines work by using pressure to ignite the diesel instead of a spark plug
