0:01 Тhe internal combustion engine is used motorcycles automobiles boats trucks
0:06 aircraft ships heavy-duty machinery and powered generators.
0:11 А four stroke engine is an internal combustion engine in which the piston
0:15 completes four separate strokes intake compression power an exhaust your into
0:20 separate revolutions of the engines crankshaft in one single thermodynamic
0:25 cycle let's take a look at the basic internal parts of the four stroke engine
0:30 inside the engine block
0:31 there was a crank shaft
0:33 piston rods are attached to crank shaft
0:36 pistons are attached to the pistons rods
0:39 as the crankshaft terms in causes the lifter to make each pass to move up and
0:44 down
0:45 at the top of the crankshaft there was a camshaft which is connected to the
0:48 crankshaft by a timing belt
0:51 wildly crankshaft is making the pistons move up and down the camshaft is turning
0:56 making the valves to open enclose
1:04 let's now take a look at how the combustion creates pistons motion
1:09 intake stroke
1:11 the inlet valve is opened
1:13 and the fuel air mixture is drawn in
1:16 as the peston travels down
1:19 compression stroke the inlet valve is closed
1:23 and a piston travels back at the cylinder
1:26 compressing the fuel air mixture
1:28 just before piston reaches the top of its compressions stroke
1:32 a spark plug emits a spark to combust the fuel air mixture
1:37 there'd
1:38 combustion stroke that justin is now forced down by the pressure wave of the
1:43 combustion of the few layer mixture
1:46 the engines power is derived
1:48 from this cycle
1:50 fourth exhaust stroke the exhaust untill is opened
1:55 and a piston travels back up
1:57 expelling the exhaust gases through the exhaust valve
2:02 at the top of the stroke the exhaust intel is closed
2:06 this process is repeated
2:08 would have been presented is the cycle of operation of one cylinder over four
2:13 stroke engine
2:15 generally engines have two or more cylinders acting in concert with each
2:19 other to produce the engine power
