Enhancing the performance of components exposed to high thermal stress in turbocharged medium-speed diesel engines
Abstract
The study examines the influence of local overheating in the joint area between the cylinder cover and the cylinder liner on their stress–strain state and the gas-joint tightness of forced medium-speed diesel engines (MSDEs) with a suspended cylinder liner design. The aim of the work is to evaluate the effect of various additional local cooling configurations applied to the structural elements forming the engine’s gas joint on their thermal loading and sealing performance. Based on a three-dimensional finite element analysis, the numerical investigation produced temperature, deformation, and stress fields for the components of the considered cylinder cover–liner module of an MSDE. Recommendations are provided to improve the cooling efficiency of the gas-joint zone and enhance its reliability under engine boosting (forced operation).
