Method for Operating an Internal Combustion Engine System and Internal Combustion Engine System

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a method and system for operating an internal combustion engine. The key feature is preparing a fuel-air mixture and delivering it to a pre-chamber at a pressure higher than ambient. The method also includes measures to increase the condensation point of the fuel-air mixture, which prevents components of the fuel from condensing on the walls of the supply line as the pressurized mixture is delivered.

Use CasesContent extracted from patent full text and abstract with AI.

• Automotive engines (cars, trucks, motorcycles) seeking to improve efficiency and reliability
• Industrial engines powered by internal combustion (generators, pumps)
• Marine or aviation engines requiring optimized fuel delivery under variable environmental conditions
• Retrofit systems to upgrade existing combustion engines to prevent fuel condensation issues

BenefitsContent extracted from patent full text and abstract with AI.

• Prevents fuel condensation in the supply lines, reducing potential engine starting or operation problems
• Improves the reliability and efficiency of the fuel delivery system
• Helps maintain consistent engine performance across different environmental conditions
• Reduces maintenance needs and potential clogging or damage caused by condensed fuel components

Patent Abstract

Bei einem Verfahren zum Betrieb eines Verbrennungsmotorsystems (1) wird ein Kraftstoff-Luft-Gemisch bereitgestellt und dieses einer Vorkammer (20) des Verbrennungsmotors (2) des Verbrennungsmotorsystems (1) bei einem gegenüber Umgebungsdruck erhöhten Systemdruckwert zugeführt. Außerdem wird mittels wenigstens einer Maßnahme der Kondensationspunkt des Kraftstoff-Luft-Gemischs gegenüber wenigstens einem Wert wenigstens einer Umgebungsbedingung erhöht, um eine Kondensation von im Kraftstoff-Luft-Gemisch enthaltenen Kraftstoffkomponenten an einer Wandung einer Zuleitung (22) zur Vorkammer (20) während oder nach der Druckbeaufschlagung zu vermeiden.
