Abstract
(DE) Bei der Schmierung der Zylinder (1) von Säure generierende Brennstoffe verbrennenden Verbrennungsmotoren bei der mehrere Schmierstoffe mit unterschiedlichem Neutralisierungsvermögen Verwendung finden lassen sich dadurch eine Optimierung der Schmierung und der Säureneutralisierung und damit eine hohe Betriebssicherheit und Wirtschaftlichkeit erreichen, dass zumindest ein Schmierstoff mit einem Neutralisierungsvermögen, das bei keinem in Frage kommenden Einsatzfall über den benötigten Neutralisierungsbedarf hinausgeht, und mindestens ein Schmierstoff mit einem Neutralisierungsvermögen, das bei keinem in Frage kommenden Einsatzfall kleiner als der benötigte Neutralisierungsbedarf ist, Verwendung finden und dass die verwendeten Schmierstoffe individuell in der Menge dosiert der Zylinderinnenseite zugeführt werden, wo ein Verschnitt erfolgt.
(EN) The invention relates to the lubrication of the cylinders (1) of internal combustion engines that burn acid-generating fuels, wherein several lubricants having different neutralization capability are used. According to the invention an optimization of the lubrication and of the acid neutralization and thus high operational reliability and economic efficiency can be achieved in that at least one lubricant having a neutralization capability that does not exceed the neutralization requirement in any possible use case and at least one lubricant having an neutralization capability that is not less than the neutralization requirement in any possible use case are used and that the lubricants used are individually fed to the cylinder interior in metered amounts and are mixed in the cylinder interior.
(FR) Lors de la lubrification des cylindres (1) de moteurs à combustion interne employant des combustibles générant de l'acide, pour laquelle plusieurs lubrifiants ayant une capacité de neutralisation différente sont utilisés, on obtient une optimisation de la lubrification et de la neutralisation d'acide et par conséquent une sécurité de fonctionnement et une efficacité élevées en utilisant au moins un lubrifiant ayant une capacité de neutralisation qui ne dépasse la demande de neutralisation dans aucune application entrant en ligne de compte, et au moins un lubrifiant ayant une capacité de neutralisation qui n'est inférieure à la demande de neutralisation dans aucune application entrant en ligne de compte, et en amenant les lubrifiants utilisés en quantité dosée individuellement jusqu'à la face interne du cylindre où un mélange se produit.
