Abstract

ινητήρας εσωτερικής καύσης που η κυλινδροκεφαλή (3) φέρει μια κοινή βαλβίδα (4) ανά κύλινδρο που κινείται από έκκεντρο (5) και δύο δευτερεύουσες βοηθητικές βαλβίδες (7),(8) εναλλακτικά (19),(20) που υποβοηθούν τους χρόνους εισαγωγής και εξαγωγής. Οκάθε κύλινδρος (1) του κινητήρα και σε προκαθορισμένο ύψος φέρει θυρίδα (26) στην οποία τοποθετείται βαλβίδα μεταβολής κυβισμού (25) και εναλλακτικά(27) από την οποία διαφεύγει ελεγχόμενη ποσότητα αέρος κατά την συμπίεση και όταν θέλουμε να επιτύχουμε μεταβολή στον κυβισμό. Με την κοινή βαλβίδα (4) εισαγωγής-εξαγωγής μπορούμε να αυξήσουμε τη σχέση συμπίεσης σε υψηλούς βαθμούς αφού αυτή ψύχεται επαρκώς αποφεύγοντας έτσι τα φαινόμενα αυταναφλέξεων. Με την βαλβίδα μεταβολής κυβισμού μπορούμε, όταναυτό είναι επιθυμητό, να μειώσουμε τον κυβισμό του κινητήρα και κατά συνέπεια την κατανάλωση καυσίμου και την εκπομπή ρύπων του. ΰ
