Improving a spring liner design for a cylinder piston group

The engine is one of the most important and complex parts of the car. Most of the breakdowns occur in the piston group of the internal combustion engine, especially in the compression rings. This article presents a new design for an innovative repair kit for transport equipment units. Article considers new principles and effects for reducing friction in vehicle units. The main difference of the new solution is the use of spring rings instead of simple installation of compression piston rings. The main goal of functional tuning is to increase the strength and technical indicators of friction between piston rings and cylinder liner. New technology decreases the natural wear of piston rings and the integrity of piston grooves in which the rings are installed. Moreover, new kit improves seals and increases shock absorption when the combustible mixture ignites. Suggested spring kit is tested in virtual environment with all with external factors and processes that can affect the operation of the spring. Based on the results of the experiments and mathematical calculations, suggested kit can work under the real working conditions without any deformation and losing functionalities.
