1. 1. Development of a 3D Ring Dynamics Model For a Heavy-Duty Piston Ring-Pack

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Parthasri Akurati; Karan Kumar; [2021]
   Keywords : 3D ring model; Flank wear; Oil consumption; Piston ring dynamics;

   Abstract : With the increasing restrictions in emission legislations, the automotive industry aims to improve the efficiency of the lubricating system and to decrease fuel consumption. In the power cylinder unit (PCU), the piston rings are the major contributor to these consumptions. READ MORE

3. 2. Experimental Study of Metallic Surfaces Exposed to Cavitation

   University essay from KTH/Materialvetenskap

   Author : Marcio Freitas De Abreu; [2018]
   Keywords : cavitation; cylinder liner; lamellar gray cast iron; erosion pitting; graphite class; cavitation;

   Abstract : Cylinder liners in heavy-duty truck engines are subjected to intense vibrations and may sustain damage from the cavitation of bubbles in the coolant liquid, with some risks of leakage and engine breakdown. An ultrasonic oscillating probe was used to simulate the pitting rates and behavior of samples extracted from cylinder liners, which are made of grey cast iron, with differences in surface roughness, glycol and inhibitor content in coolant, coolant temperature and graphite flake class; bainitic microstructures were also tested.

4. 3. Tribological evaluation of the contact between upper compression ring and cylinder liner with different surface coatings

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik

   Author : Pär Wassborg; [2016]
   Keywords : piston ring; cylinder liner; wear; friction; grey cast iron; titanium oxide; chromium oxide;

   Abstract : The constant pursuit in the automotive industry to increase the engines performance, new solutions are always developed and tested to reduce the friction and increase the efficiency in the engine. One component that contributes to friction losses is the piston ring pack where the top compression stands for up to 40 %. READ MORE

5. 4. The impact of honing process parameters on the surface quality of cylinder liners

   University essay from KTH/Industriell produktion

   Author : Sofia Edberg; Erik Landqvist; [2015]
   Keywords : ;

   Abstract : During recent years, legislation regarding emissions and fuel consumption levels for the automotive industry has become increasingly comprehensive. In order for automotive manufacturers to reach the demands, engine friction needs to be reduced. READ MORE

6. 5. Integrated engine waste heat recovery by combination ofevaporative engine cooling and Rankine bottoming cycle.

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Vincent Choquet; [2014]
   Keywords : ;

   Abstract : Engine Cooling losses constitutes about 20% of the injected fuel energy in a modern heavy duty truck diesel engine. The objective of this Master Thesis Project is to investigate flow boiling cooling as a thermally efficient method for waste heat recovery as well as a good solution for precision cooling. READ MORE
