An Innovative On-Line Measurement Method for Studying the Impact of Lubricant Formulations on Poisoning and Clogging of After-Treatment Devices 2005-01-2178
The lifetime of the new technologies of after-treatment devices is influenced by the composition of engine oil, making it necessary to study the compatibility of lubricants with these devices. These compatibility tests usually evaluate parameters such as the long-term performance of after-treatment systems, the quantity and nature of accumulated residues due to the lubricant used, back-pressure increase, etc.
This paper presents a novel, non-destructive radionuclide technique based on labeling the different elements in the engine oil (e.g. zinc and calcium), that provides additional information to after-treatment system compatibility tests: on-line measurement in the after-treatment device of the accumulation of elements from oil additives, and visualization of their distribution inside the device (inlet/outlet). Most of the work presented here focuses on the accumulation of zinc and calcium from the lubricant in a Diesel Particulate Filter (DPF). The quantities of non-combustible deposits formed in the DPF by two lubricants having different sulfated ash levels are compared.
