Opportunities for P/M in Variable Valve Timing Devices
Bibliographic record
Abstract
<div class="htmlview paragraph">Variable Valve Timing (VVT) is a new technology that provides many opportunities for P/M components. A VVT device (also call VCT, variable cam timing, or cam phaser) allows for the timed relationship between an engine camshaft and engine crankshaft to be changed. Prior to VVT, camshafts were synchronized through gears or timing chains. VVT is applied to the timing sprockets or gears so that the relationship between the toothed element and camshaft are adjusted based on engine variables. Many engines now feature VVT and more are scheduled to employ VVT in the future. There are many different types of VVT devices. The type of VVT device commonly referred to as “vane type” contains inner and outer components that are well suited for P/M manufacture. They will be described and reviewed with respect to manufacture by P/M.</div>

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
