Abstract
يتعلق الاختراع بوسيلة لاسترداد جزء من الطاقة المهدورة من غازات العادم لمحركات الاحتراق الداخلي بأربعة أشواط. وتتوافق هذه الاستعادة مع التكنولوجيات القائمة سامحة بتحسين المردودية الطاقية للمحرك وتقليل استهلاك الوقود. تتمثل منهجية هذا الاختراع في تثبيت مجموعة مضافات تسمح بأخذ جزء من الغازات المنبعثة من الاحتراق انطلاقا من اسطوانة توجد في النصف الثاني لطور الانبساط وإدخالها في اسطوانة التي هي في طور الضغط. فيما يضمن نقل الغاز في انبساط ضغط الغازات ويتم توجيهه والتحكم فيه من خلال أنابيب مغلقة من قِبل صمامات تقع في منفذ غرف احتراق مصادر الاسطوانات المصدر والمستهدفة.حسب اختيار تصميم المحركات، يمكن أن يتم نقل الغاز دفعة واحدة أو مؤخرا بمكوث قصير في الأنابيب التي تُستخدم إذن كأماكن للتخزين المؤقت.وتوفر الغازات المنبعثة من مرحلة نهاية انبساط الطاقة الحرارية، الطاقة الحركية وكميات من الهواء تسمح برفع درجة حرارة وضغط الخلائط الحاضرة بداية في الاسطوانة المستقبلة إلى مستويات أعلى. وقد تعمل هذه العملية على تحسين أداء دورة المحرك. يتم احتساب نقل الغازات بين مختلف الاسطوانات بشكل يعمل على تحسين الزيادة في الأداء للاحتراق المقبل مع اعتبار فقدان الضغط في نهاية انبساط الاسطوانة الأولى. الفوائد التي يستهدفها الاختراع الحالي هي إمكانية تحسين أداء الاحتراق مع حد أدنى من استهلاك الطاقة، التوافق والتكامل مع التقنيات الأخرى قبل هذا الغرض نفسه، هذا مع الحفاظ على حجم ووزن المحرك بما إن القطع الاضافىة هي ذات حجم صغير وتدمج في التصميم الأساسي.The invention relates to a means of recovering part of the waste energy from the exhaust gases of internal combustion engines by four strokes. This recovery is compatible with existing technologies allowing for improved engine energy efficiency and reduced fuel consumption. The methodology of this invention consists in fixing a group of additives that allow a fraction of the gases from the combustion to be taken from a cylinder in the second half of the diastole phase and inserted into a cylinder under pressure. The gas is transported in the flat pressure of the gases and is directed and controlled through closed pipes by valves located at the outlet of the source and target cylinder combustion chambers. The gases emitted from the end of the diastolic phase provide thermal energy, kinetic energy and amounts of air that allow the temperature and pressure of the mixtures present in the receiving cylinder to be raised to higher levels. This process may improve engine cycle performance. The transfer of gases between the different cylinders is calculated to improve the performance increase for the next combustion taking into account the pressure loss at the end of the first cylinder. The benefits of the present invention are the possibility of improving combustion performance with minimum energy consumption, compatibility and integration with other technologies prior to this same purpose, while maintaining the size and weight of the engine since the additional parts are small in size and incorporated into the basic design.
