Перевод:
Когда поршень снова достигает верхней мертвой точки, свечи зажигания воспламеняют смесь, оба клапана закрываются во время сгорания. В результате горения смеси газы расширяются, и большое давление заставляет поршень двигаться вниз по цилиндру. Этот ход называется силовым ударом. Когда поршень достигает нижней точки своего хода, выпускной клапан открывается, давление сбрасывается, и поршень снова поднимается. Это позволяет сгоревшему газу течь через выпускной клапан в атмосферу. Это называется выхлопной печью, которая завершает цикл. Таким образом, поршень перемещается в цилиндре вниз (такт впуска), вверх (такт сжатия), вниз (рабочий ход), вверх (такт выпуска). Тепло, выделяемое топливом, преобразуется в работу, так что возвратно-поступательное движение поршней преобразуется во вращательное движение коленчатого вала с шатунов.
Вопрос-ответ:
1) As the piston again reaches the top dead center the spark plugs ignite the mixture.
2) High pressure causes the piston to move down the cylinder.
3) When the piston reaches the bottom of its stroke, the exhaust valve opens, the pressure is released, and the piston rises again.
4) The drain that completes the cycle is called the exhaust furnace.
5) The piston moves in the cylinder down (intake stroke), up (compression stroke), down (stroke), up (exhaust stroke).
