  • 1 Fuels and Combustion Bengt Johansson
    1 1 Fuels and Combustion Bengt Johansson 1.1 Introduction All internal combustion engines use fuel as the source for heat driving the thermo- dynamic process that will eventually yield mechanical power. The fuel properties are crucial for the combustion process. Some combustion processes require a fuel that is very prone to ignition, and some have just the opposite requirement. Often, there is a discussion on what is the optimum. This optimum can be based on the fuel or the combustion process. We can formulate two questions: • What is the best possible fuel for combustion process x? • What is the best possible combustion process for fuel y? Both questions are relevant and deserve some discussion, but it is very seldom that the fuel can be selected without any considerations, and similarly, there is only a limited selection of combustion processes to choose from. This brief intro- duction discusses the combustion processes and the link to the fuel properties that are suitable for them. Thus, it is more in the line of the first question ofthe aforementioned two. 1.2 The Options For internal combustion engines, there are three major combustion processes: • Spark ignition (SI) with premixed flame propagation • Compression ignition (CI) with nonpremixed (diffusion) flame • Homogeneous charge compression ignition, HCCI with bulk autoignition of a premixed charge. These three processes can be expressed as the corner points in a triangle accord- ing to Figure 1.1. Within this triangle, all practical concepts reside. Some are a combination of SI and HCCI, some a combination of SI and CI, and others a Biofuels from Lignocellulosic Biomass: Innovations beyond Bioethanol, First Edition.

  • The Influence of Lubricant Degradation on Measured Piston Ring Film Thickness in a Fired Gasoline Reciprocating Engine
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Bradford Scholars The Influence of Lubricant Degradation on Measured Piston Ring Film Thickness in a Fired Gasoline Reciprocating Engine Rai Singh Notay1), Martin Priest2) and Malcolm F Fox2) 1) [email protected] 2) Faculty of Engineering and Informatics, University of Bradford, Bradford, BD7 1DP, UK Abstract A laser induced fluorescence system has been developed to visualise the oil film thickness between the piston ring and cylinder wall of a fired gasoline engine via a small optical window mounted in the cylinder wall. A fluorescent dye was added to the lubricant in the sump to allow the lubricant to fluoresce when absorbing laser radiation. The concentration of the dye did not disturb the lubricant chemistry or its performance. Degraded engine oil samples were used to investigate the influence of lubricant quality on ring pack lubricant film thickness measurements. The results show significant differences in the lubricant film thickness profiles for the ring pack when the lubricant degrades which will affect ring pack friction and ultimately fuel economy. 1. Introduction With the drive towards better energy resource utilisation and an improved environment, current automotive engine tribology research is geared towards reduced pollutant emissions and improved efficiency. A large proportion of the internal friction of an engine is due to the piston assembly, comprising the piston ring pack and the piston skirt, and the lubricant in the ring pack also plays a vital role in exhaust emissions control [1, 2]. Demands on the engine lubricant to help improve engine efficiency are becoming more intense and recent engine technology, such as engine downsizing and stop start functions, are increasing the stress on modern engine lubricants.

  • The Rotating Liner Engine (RLE) Diesel Prototype: Reducing Internal Engine Friction by About 40% Under Idle Conditions
    applied sciences Article The Rotating Liner Engine (RLE) Diesel Prototype: Reducing Internal Engine Friction by about 40% under Idle Conditions Dimitrios Dardalis 1,*, Amiyo Basu 2,*, Matt J. Hall 2,* and Ronald D. Mattthews 2,* 1 RSET Inc., University of Texas at Austin, Austin, TX 78712, USA 2 University of Texas at Austin, Austin, TX 78712, USA * Correspondence: [email protected] (D.D.); [email protected] (A.B.); [email protected] (M.J.H.); [email protected] (R.D.M.) Abstract: The Rotating Liner Engine (RLE) concept is a design concept for internal combustion engines, where the cylinder liner rotates at a surface speed of 2–4 m/s in order to assist piston ring lubrication. Specifically, we have evidence from prior art and from our own research that the above rotation has the potential to eliminate the metal-to-metal contact/boundary friction that exists close to the piston reversal areas. This frictional source becomes a significant energy loss, especially in the compression/expansion part of the cycle, when the gas pressure that loads the piston rings and skirts is high. This paper describes the Diesel RLE prototype constructed from a Cummins 4BT and the preliminary observations from initial low load testing. The critical technical challenge, namely the rotating liner face seal, appears to be operating with negligible gas leakage and within the hydrodynamic lubrication regime for the loads tested (peak cylinder pressures of the order of 100 bar) and up to about 10 bar BMEP (brake mean effective pressure). Preliminary testing has proven that the metal-to-metal contact in the piston assembly mostly vanished, and a friction reduction at idle conditions of about 40% as extrapolated to a complete engine has taken place.
