These exhaust gas and particulate matter emissions limited by law confront the engine developers with a difficult task that can only be solved in the combination combustion – exhaust gas after-treatment – oil consumption development. MEASUREMENT PRINCIPLE The measurement works in accordance with the gravimetric principle. This means drawing the oil into a measurement tank, either completely or up to a defined level, by means of a modified dip stick or the oil drain plug. Afterwards, the weight is determined with the help of a high-precision pressure sensor. After the weight has been determined, the oil is pumped back into the oil pan of the engine. A measurement cycle consists of the three steps of pumping out, weighing and pumping back. The difference between two subsequent measurement cycles indicates the oil consumption. APPLICATION Thanks to the compact and mobile design, the measurement unit can be used in many applications. The areas of application in the field of engine development and research are the optimization of cylinder head seals, piston rings, the valve guides, as well as inspection of oil dilution or the reasons for oil consumption. In durability testing, the AVL Oil Consumption Meter can also be used for monitoring or refilling the consumed quantity of oil. On production testbeds the meter can be used to check the production quality of the engines. BENEFITS AT A GLANCE • Up to 50% time savings compared to traditional methods • The integrated oil refilling unit allows extended test cycles • The simple installation and testbed integration minimizes downtime • The integrated operating panel on the device allows stand-alone operation • Due to the fully automated measurement procedure, there is no need to handle the oil OIL CONSUMPTION MEASUREMENT 1 Oil dip stick 2 Measuring tank 3 Refilling tank 4 Pump 5 Drain plug 6 Electronics 7 PUMA CDH – Task 8 Hybrid interface or serial interface via RS232 Available online via AVL ePRODUCTS https://shop.avl.com
