  • A Second Law analysis of the processes within a diesel engine is presented and compared with the traditional First Law analysis. The analysis technique is described and its assumptions outlined. Available energy additions, extractions, and destructions are examined and quantified for the various processes. Alternative approaches are presented for engine systems with or without secondary heat recovery devices to further quantify the relative importance of thermodynamic loss mechanisms. The technique is applied to a turbocharged diesel engine and used to track available energy throughout the engine cycle. The methods of analysis are applied to some simplified cases to demonstrate theirmore » usefulness in analyzing various engine processes.« less
  • The objective of this research was to obtain diesel particle size distributions from a 1988 and a 1991 diesel engine using three different fuels and two exhaust control technologies (a ceramic particle trap and an oxidation catalytic converter). The particle size distributions from both engines were used to develop models to estimate the composition of the individual size particles. Nucleation theory of the H{sub 2}O and H{sub 2}SO{sub 4} vapor is used to predict when nuclei-mode particles will form in the dilution tunnel. Combining the theory with the experimental data, the conditions necessary in the dilution tunnel for particle formationmore » are predicted. The paper also contains a discussion on the differences between the 1988 and 1991 engine`s particle size distributions. The results indicated that nuclei mode particles (0.0075--0.046 {micro}m) are formed in the dilution tunnel and consist of more than 80% H{sub 2}O-H{sub 2}SO{sub 4} particles when using the 1988 engine and 0.29 wt% sulfur fuel. Nucleation theory indicated that H{sub 2}O-H{sub 2}SO{sub 4} particles may form during dilution at 0.03 wt% fuel sulfur levels and above. The 1991 engine was designed for lower particulate emissions than the 1988 engine and the 1991 engine`s accumulation mode particles (0.046-1.0 {micro}m) were reduced more than 80% by volume compared to the 1988 engine using the same low sulfur fuel. The particle size composition model indicated that using low sulfur fuel and the 1991 engine, the nuclei mode contained more than 45% of the total solid particles and over 85% of the soluble organic fraction.« less
  • This SAE special publication, Applications of New Diesel Engine and Component Design (SP-1158), is a collection of papers from the New Diesel Engines and Components sessions of the 1996 SAE International Congress and Exposition. The topics of the papers include cylinder liners, oil rings, diesel engines, applications of plastics and ceramics in heat engine design, valve trains, tribology and torsional vibration of crankshafts.
  • Introduction of the 1600 Diesel Engine required Ford to reappraise their engine testing philosophy and to install new production testbeds. This paper outlines the engine, describes the test cycles chosen and the engine performance data that were sought from the hot test and overcheck beds. A technical description of the testbeds and computer control systems is given.
  • New 6 cylinder direct injection 11 liter diesel engines which have naturally aspirated, turbocharged, and turbocharged-aftercooled versions have been developed and moved in production at the end of 1983. The highest output of the turbocharged-aftercooled version is 276 kW (375 ps) at 2200 RPM. Based on Komatsu new technologies 125 mm bore diesel has been designed to meet the users' demands, such as compact in size, light in weight, extremely high performance, high reliability and durability. The turbocharged and turbocharged-aftercooled engines are characterized by the adoption of the ductile cast iron piston which is the first application into the highmore » speed, four cycle diesels in production in the world, and which was enabled by Komatsu design and precision casting technologies. This paper also covers the other design aspects and performance characteristics.« less
