Continuously increasing stringency of emission legislation such as Euro 2 and Euro 3 require the Engine Designer and Manufacturer to strive for further reduction in lubricating oil consumption. Increased customer expectation, depletion of natural resources and increase in competition are also other drivers to focus on oil consumption reduction.
In order to reduce the oil consumption and, in turn emissions, an extensive theoretical and experimental investigation was carried out on a 2.5 l DI Diesel engine. The key factors affecting the oil consumption like liner surface finish, cylinder liner distortion, piston and piston ring design, oil film thickness, and inter ring pressure balancing were analyzed and optimized..
The ring pack dynamics was studied using Ricardo RINGPAK software as a simulation tool.
This paper presents an overview of various analytical and experimental studies done to reduce oil consumption.
Through this approach it was possible to achieve a reduction of 50% in oil consumption without sacrificing on the durability and cost of the engine.
