![]() Words in double quotes " " are treated as a phrase. For example, searching for t?re would match both tire and tyre Using Quotes Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, entering a keyword search of aero* will search for any word beginning with aero. Using the asterisk, ( * ) allows you to search for a partial word. SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search. This means that your search results will contain all results that contain ANY of the entered terms. Please note: All terms not contained within quotes, will be evaluated using the OR operator.

Homogeneous Charge Compression Ignition with a Free Piston: A New Approach to Ideal Otto Cycle Performance SAE Technical Paper 982484 1998 10.4271/982484 The Free Piston Linear Generator - Development of an Innovative, Compact, Highly Efficient Range-Extender Module SAE Technical Pa10.4271/27 These conclusions were confirmed through experiments with the prototype FPEG. ![]() Simulations conducted with this model clarified that the FPEG can be operated stably and efficiently with high robustness under the conditions of this study and that the base pressure of the air spring chamber must be set in accordance with the injected fuel mass. To investigate the potential of this control method, a one-dimensional simulation model was developed. To control the piston position at the beginning and end of the stroke, speed control commands for the linear generator are determined based on the position errors at the beginning and end of the stroke. Thus, it is preferable for the linear generator to function only in the middle of the stroke, allowing the piston to move freely during the remainder of the stroke. The piston speed is zero at the beginning and end of the stroke and reaches a maximum at the middle of the stroke. In general, the generating efficiency of linear generators is low in the low-speed region. ![]() This paper describes a novel linear generator control method which realizes the simple harmonic oscillation governed by the piston mass and the air spring pressure. Among these technical challenges, the piston motion control is the most significant factor in improving the robustness and efficiency of the FPEG because the combustion characteristics depend strongly on the piston motion, which is controlled by the linear generator. There are some technical challenges in ensuring an FPEG can achieve continuous operation over a long period, including lubrication, cooling, and piston motion control. The FPEG consists of a two-stroke combustion system, a linear generator, and a gas spring chamber. ![]() A free piston engine linear generator (FPEG) with potential for compact build, high efficiency and high fuel flexibility was developed in this study. ![]()
