Le terme exprime une exigence de carburant ; il ne signifie pas que tout moteur \u00e0 essence peut les utiliser sans modification.<\/p>\n<p>La compatibilit\u00e9 d\u00e9pend d\u2019un moteur, d\u2019un circuit de carburant, d\u2019une calibration et d\u2019une enveloppe de fonctionnement pr\u00e9cis. Un moteur pr\u00e9sent\u00e9 avec un carburant ne doit pas \u00eatre consid\u00e9r\u00e9 automatiquement comme valid\u00e9 avec tous les autres carburants lourds.<\/p>\n<h2>Injection directe et injection indirecte<\/h2>\n<p>L\u2019injection directe introduit le carburant dans la chambre de combustion. L\u2019injection indirecte l\u2019introduit en amont, par exemple dans un conduit d\u2019admission ou un bo\u00eetier papillon. Ces architectures ont des exigences mat\u00e9rielles et de commande diff\u00e9rentes.<\/p>\n<p>Cette distinction ne suffit pas \u00e0 d\u00e9terminer le syst\u00e8me adapt\u00e9 \u00e0 un a\u00e9ronef. Il faut \u00e9valuer le moteur retenu selon le carburant, la puissance, les conditions de fonctionnement, l\u2019installation et l\u2019assistance n\u00e9cessaires.<\/p>\n<h2>Le d\u00e9marrage \u00e0 froid est une exigence distincte<\/h2>\n<p>Montrer un moteur chaud fonctionnant avec un carburant ne prouve pas sa capacit\u00e9 \u00e0 d\u00e9marrer \u00e0 froid avec ce carburant. Demandez au fournisseur de distinguer carburant de d\u00e9marrage et carburant de fonctionnement, et de pr\u00e9ciser tout chauffage, transition ou \u00e9quipement auxiliaire requis.<\/p>\n<p>Pr\u00e9cisez les conditions ambiantes pr\u00e9vues. Une temp\u00e9rature annonc\u00e9e n\u2019est utile qu\u2019avec la configuration moteur, le carburant et la proc\u00e9dure d\u2019essai correspondants. Cet article ne donne aucun seuil de temp\u00e9rature universel applicable \u00e0 tous les moteurs.<\/p>\n<h2>Que doit contenir une d\u00e9claration de compatibilit\u00e9<\/h2>\n<ul>\n<li>La sp\u00e9cification exacte du carburant et les alternatives autoris\u00e9es.<\/li>\n<li>Le mat\u00e9riel moteur, le syst\u00e8me de lubrification et les composants du circuit de carburant.<\/li>\n<li>Les versions du calculateur et de la calibration, ainsi que la proc\u00e9dure de d\u00e9marrage.<\/li>\n<li>Les performances mesur\u00e9es et limites de fonctionnement de cette configuration.<\/li>\n<li>Les exigences de maintenance et les preuves justifiant l\u2019usage pr\u00e9vu.<\/li>\n<\/ul>\n<p>Modifier uniquement la cartographie ne prouve pas que toutes les autres questions de compatibilit\u00e9 sont r\u00e9solues.
