01:22So, today
01:24First of all
01:26We are going to talk about
01:28Engine
01:30Many of you
01:32Don't know how to run an engine
01:34And where to get power
01:36So, today
01:38We are going to see a basic thing
01:40That is
01:42How an engine delivers power
01:44And how it is done
01:46So, basically
01:48To run an engine
01:50A fuel, air
01:52And to fire it
01:54An ignition system
01:56And to take it out
01:58An exhaust system
02:00So, basically
02:02Inside a compression chamber
02:04When a fuel goes inside
02:06When a fire is lit
02:08There will be an explosion
02:10So, through that explosion
02:12The engine runs
02:14To connect that
02:16There will be a powertrain
02:18And through that fuel
02:20Power will be generated
02:22So, this is a basic thing
02:24But, now
02:26This step
02:28Certain types of engines
02:30There are many types of engines
02:32So, let's take the stroke setup
02:34When we take it in a bike
02:36Two stroke engine, four stroke engine
02:38You would have heard
02:40So, two stroke, four stroke
02:42What is the difference between these two
02:44I will tell you now
02:46So, in two stroke
02:48Power will be generated in two strokes
02:50But, in four stroke, power will be generated
02:52So, let me show you
02:54So, in two stroke
02:56Here
02:58There is a piston cylinder
03:00When the piston comes down
03:02Fuel and air
03:04Get mixed
03:06And compresses
03:08In one stroke
03:10In second stroke
03:12Explosion and expansion happens
03:14So, this compression
03:16Is ignited by the spark plug
03:18So, when the explosion happens
03:20Another valve opens
03:22And your expansion
03:24Exhaust comes out
03:26Exhaustion happens
03:28So, when the exhaustion happens
03:30In this
03:32In two stroke
03:34The whole process ends
03:36In second stroke, power is generated
03:38Next is
03:40Four stroke
03:42In this four stroke, you have four steps
03:44So, basically
03:46Suction, Compression, Explosion
03:48And Exhaustion
03:50So,
03:52I will tell you how this setup works
03:54First, the piston is up
03:56When it comes down, the valve opens
03:58And the fuel and air comes in
04:00Second, this piston goes up
04:02And compresses
04:04So, in that place, stroke two
04:06Compresses
04:08In stroke three, explosion happens
04:10Spark plug ignites
04:12Explosion happens
04:14Piston comes down with full pressure
04:16So, after that
04:18In this place
04:20It goes up again
04:22That's why we have a crank wheel
04:24It has a weight balancing
04:26So, this crank wheel
04:28Helps in going up and coming down
04:30So, when it comes down
04:32It goes up again
04:34So, basically when the piston goes down
04:36There is a lump in the crank wheel
04:38We have seen that
04:40A little cross
04:42So, when it comes down
04:44The weight pulls the piston up
04:46So, this is how the piston works simultaneously
04:48So, again, when the piston goes up
04:50The exhaust valve opens
04:52Exhaust happens
04:54So, this is four stroke
04:56In this place,
04:58Explosion happens in third stroke
05:00In that place, power is generated
05:02So, this is called power band
05:04Because in that place
05:06Maximum power is produced
05:08So, two stroke
05:10Because performance is high
05:12Power is generated in second stroke
05:14But in four stroke
05:16Power is generated in third stroke
05:18That's why two stroke
05:20Today, two stroke
05:22They have taken that place
05:24That's why there is a lot of power
05:26Because it is very fast
05:28But four stroke also has a lot of power
05:30Because today, technology
05:32Economical, pollution norms
05:34Today, in four stroke
05:36We are seeing a lot of vehicles
05:38So, this is a basic step
05:40Now, this process
05:42In simultaneous
05:44It is happening repeatedly
05:46This is how an engine
05:48Is run
05:50So, this
05:52You have a piston
05:54That is a compression chamber
05:56It is tight
05:58There is a piston
06:00There is a link rod to connect the piston to the crank wheel
06:02So, this rod is
06:04Connecting the piston to the crank wheel
06:06At one end of the crank wheel
06:08We have connected a chain sprocket
06:10From that
06:12We take power delivery output
06:14From the wheel
06:16So, this is a basic
06:18Engine running setup
06:20If this engine runs
06:22There is a certain RPM speed
06:24There is a capability
06:26In that speed, maximum speed
06:28We are rotating
06:30After that, it will be
06:32Rotating at a peak RPM
06:34So, in this place
06:36To adjust this power
06:38For you
06:40Acceleration
06:42Throttle body kit
06:44Plus, they have brought a
06:46Gear box setup
06:48So, it is rotating at a speed
06:50But, to divide that speed
06:52To give
06:54I have brought a gear box setup
06:56So, if you give this much power to the first gear
06:58To the second gear, this much
07:00To the third gear, this much
07:02To the fifth gear, this much
07:04That power is distributed through this gear box
07:06It produces only one power
07:08But, to distribute that power
07:10Is a gear box
07:12Next is the carburetor acceleration setup
07:14So, in this throttle
07:16How much fuel should go to this engine
07:18Where the fuel should go less
07:20This carburetor or fuel
07:22Is the setup to decide
07:24In modern technology
07:26Fuel injector system
07:28Throttle body
07:30There is a butterfly valve in the throttle body
07:32When you give the accelerator
07:34It will open
07:36Based on the amount of fuel
07:38Speed, low, speed, flow
07:40If you don't get air or fuel
07:42The car will start to get off
07:44So, if the fuel is less
07:46The power band will be exposed
07:48That power will be produced
07:50If the fuel is more
07:52The power will be produced
07:54So, this is the basic step
07:56This thing
07:58I will tell you later
08:00This is a big process
08:02If you liked this part 1
08:04Stay tuned for part 2
08:06See you in another video
08:08Bye, see ya
