IAV in collaboration with Cummins performed real-time on-road oil consumption measurements with a Lubrisense. Published at the 5th international Motoren Kongress, February 2018.Weiterlesen Real-time on-road oil consumption measurement
Turbocharging is one of the key technologies in current and future engine development. Due to the increasing requirements that extend beyond power output and torque alone, the internal and external mechanical components of turbochargers are being subjected to an ever-increasing load spectrum.

The oil emission of a combustion engine has a direct influence on CO2 and particulate emissions. In order to determine oil emission caused specifically by the piston group, part of the exhaust gas flow is taken and analyzed using a mass spectrometer directly downstream of the exhaust valve in the exhaust manifold…

The aim of the research cluster “Fuel in Oil” is the investigation and quantification of the interaction between the fuel and the lubrication oil caused by late post injections, which are applied for the regenerationof the particulate filter or the NOx storage catalyst. To achieve the objectives, different phenomena like the fuel entry into the lubrication film, the fuel-oil transport by means of the piston rings, the evaporation of fuel out of the oil pan and the impact of the oil separator of the oil dilution were…

Modern downsizing in connection with the future more rigorous exhaust limit values for cars, commercial vehicles and off-highway applications, is a great challenge for internal combustion engine systems and components. In this context, increased oil emission leads to increased particle and HC emissions. Additionally, the efficiency of the exhaust gas aftertreatment and the pre-ignition…

The measurement of oil consumption and the investigation of oil consumption mechanisms in combustion engines are subject to various research projects. Methods like drain and weight, or such using tracers like radioactive substances, sulphur dioxide or pyrene are often too slow or insensitive for dynamic engine test cycles…

Optimisation of lube oil consumption in transient engine operation is gaining increasing attention from engine developers. Engine operation in extended stop-and-go phases can sporadically lead to unexpected oil consumption problems for inner-city driving.
