رسم توضيحي متحرك لمحرك الاحتراق الداخلي رباعي الأشواط, على مبدأ اوتو.

 وصف الأشواط

1. الهواء وبخار الوقود يـُسحبا إلى داخل المحرك.
2. بخار الوقود والهواء يتم ضغطهما واشعالهما.
3. الوقود يحترق والمكبس يـُدفع للأسفل.
4. العادم يـُصرف للخارج.

 تحذيرات وتعليقات

تحذير: This animation is not completely accurate. There should be some space left when the piston is at its highest position. The current animation suggests infinite compression.

تعليق: This is a 2D projection of a 3D model. The little space went lost in the pixels of the outlines. And a 2D projection is not able to show the space around the "roof" of the piston. (UtzOnBike) --85.182.123.226 20:58, 11 October 2006 (UTC)

تعليق: Ignition of the air-fuel mixture does not occur exactly at TDC, rather a short time before the piston reaches Top Dead Center. This is commonly referred to as BTDC and is expressed in a number of degrees of the crankshaft rotation, i.e. 8 degrees BTDC.

The ignition point varies with engine rpm. An engine rotating at such a slow speed as the one in the animation would definitely not fire at 8 degrees BTDC. IJB_TA

تعليق: It would be nicer to show the intake and exhaust by moving clouds instead of the abrupt colour changes.84.210.139.189 17:46, 18 February 2007 (UTC)

If you don't like it make a new one. IJB_TA

تعليق: I removed "injected" from the Description because this does not appear to be a fuel-injected motor.84.210.139.189 17:46, 18 February 2007 (UTC)

Why do people feel the need to endlessly criticize this animation? It shows the 4 stroke cycle VERY clearly, what else do you want? IJB_TA

I agree with the person above my comment. The picture is an excellent example of a four strike engine. Anyone who did try to make a diagram would fail miserably.17:20, 27 February 2007 (UTC)Vinaq

Hey Vinaq, is it a good exaple of a four-strOke engine then too! Oh and I reckon arrows would be ace too. Amt
