Abstract

fetched live from OpenAlex

<div class="section abstract"><div class="htmlview paragraph">In recent years, environmental regulations in the automotive industry have become increasingly strict, particularly with respect to emissions from diesel engines. Large amounts of these harmful emissions are released during the cfold start of a vehicle, due to the catalytic converter system not yet reaching its light-off temperature. This paper presents an induction heating system which heats the catalytic converter during a cold start, reducing the time for it to reach light-off temperature, and thus reducing cold-start emissions. Detailed dynamometer testing results are used to develop vehicle models of the induction heating system for a diesel Peugeot 308 light duty vehicle. The model is used to quantify the changes in hydrocarbons (HC), carbon monoxide (CO), carbon dioxide (CO<sub>2</sub>), oxygen (O<sub>2</sub>), nitrogen oxide (NO<sub>x</sub>), and fuel consumption on a variety of standard drive cycles. The results are then extrapolated to investigate the reduction of emissions possible on a Chevrolet Silverado 3500HD heavy-duty vehicle.</div></div>

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.
