Abstract

fetched live from OpenAlex

<div class="section abstract"><div class="htmlview paragraph">In order to approach the Carnot efficiency in modern diesel engines that see variable loads and high speeds, programmable electrically controlled fuel injections are required. Traditional solenoid based transducers are binary and cannot achieve this programmability while newer piezoelectric transducers are susceptible to performance degradation due to high pressures and temperatures. This paper presents the experimental characterization of a programmable diesel fuel injector transducer designed by Great Plains Diesel Technologies, L.C. to address the limitations of existing technology. This transducer employs a little-known magnetostrictive alloy to position its needle. In contrast to piezoelectric ceramics, quantum mechanics endows this alloy with the indestructible property of magnetostriction, the ability to strain proportional to a magnetic field. This allows it to be fast and infinitely adjustable (or, “programmable”) without degradation. A fuel injector based on this alloy has the inherent durability to survive on an engine while maximizing performance. In the tested prototype, the magnetostrictive rod is surrounded by a coil excited by a current pulse to energize the alloy. The prestress needed to achieve maximum performance is provided by the pressurized diesel fuel.</div><div class="htmlview paragraph">This paper presents the results of a series of tests run to determine the effect of the amplitude of the excitation current and the prestress provided by the pressurized fuel, and to characterize the amplitude and speed of the transducer output displacement and its proportionality.</div></div>

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
