    Question Субтитри на клип

    https://www.youtube.com/watch?v=OGj8OneMjek - линк на клипа
    Някой може ли да помогне със събтитрите, че не съм много запознат по темата?
    Благодаря предварително.

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

    имах предвид на български, че не се разбирам много много с английския
    ако може разбира се
