Die neue Vierzylinder-Motorenbaureihe aus der BMW/PSA-Kooperation

Die BMW Group und PSA haben in einem Kooperationsprojekt unter Federfuhrung von BMW eine neue Baureihe kleiner Ottomotoren entwickelt. Die neuen Motoren sind fur beide Partner ein wesentlicher Schritt auf dem Weg zur Reduzierung der CO2-Emissionen. Erstmals in dieser Klasse kommen ein vollvariabler Ventiltrieb (Phasen- und Hubverstellung) sowie die Kombination von Direkteinspritzung mit Aufladung mittels Twin-Scroll-Lader zum Einsatz. Eine volumengeregelte Olpumpe, eine mechanisch abschaltbare Wasserpumpe und konsequente Reibleistungsoptimierung tragen wesentlich zu einem fulligen Drehmomentverlauf und einem guten spezifischem Verbrauch aller Varianten bei.

The new four-cylinder engine series from the cooperation between BMW and PSA

With BMW providing leadership, the BMW Group and PSA have developed a new series of small petrol engines. For both partners, the new engines are a significant improvement in the task of reducing CO2 emissions. A fully variable valve drive and the combination of direct injection with turbocharging by means of a twin scroll turbocharger are being used for the first time in this vehicle class. A volume-controlled oil pump, a mechanical on-demand water pump and consistent frictional power optimisation make a considerable contribution towards achieving a generous torque characteristic and good specific fuel consumption in all variants.With BMW providing leadership, the BMW Group and PSA have developed a new series of small petrol engines.

Electric mobility – sustainably into the future

Electric mobility has been an integral part of the BMW product strategy since the introduction of the BMW i models i3 and i8 and the expansion of the model range by various plug-in-hybrid vehicles. Customer perspectives are changing worldwide in terms of future mobility and growing importance of sustainability. Therefore, BMW has identified electric mobility as one of the key factors for the future success of the company.

Computer-aided optimisation of the exhaust gas aftertreatment system of the new BMW 1.8-litre valvetronic engine

The new BMW four-cylinder engine with Valvetronic has a unique market position with respect to performance, comfort, environmental compatibility and fuel efficiency. Within the scope of the development process of the new engine generation, numerical tools have significantly reduced the engineering time and the number of hardware components. This article presents the functional properties of the exhaust gas aftertreatment system and the support of the design process by computational methods.

Computergestützte Optimierung des Abgasnachbehandlungssystems für den neuen 1,8-l-Valvetronic-Motor von BMW

Die neuen BMW Vierzylindermotoren mit Valvetronic vereinen in herausragender Weise die Eigenschaften Dynamik, Komfort, Umweltvertraglichkeit und Wirtschaftlichkeit. Im Rahmen der Entwicklung der neuen Motorengeneration trugen Simulationswerkzeuge entscheidend dazu bei, den Produktentstehungsprozess zu verkurzen und den Hardware-Aufwand zu reduzieren. Der vorliegende Beitrag stellt die funktionalen Eigenschaften des Abgasnachbehandlungssytems und die Unterstutzung des Auslegungsprozesses durch computergestutzte Methoden vor.
