Valve Arrangements TRIZ Cases
- Rocker Arm Assemblies With Hydraulic Plunger Control for Engine Braking
Hydraulic actuation extends a rocker-arm plunger for early exhaust-valve opening, enabling engine braking while limiting valvetrain wear.
- Hydrogen Engine Valve Overlap Control for Pre-Ignition
Variable valve overlap in high-load, high-rotation hydrogen engines suppresses pre-ignition, lowers cylinder temperature, and preserves scavenging.
- Engine Decompression Device With Cylinder-Specific Arm Directions
Cylinder-specific decompression-arm directions counter rotational fluctuations in multi-cylinder engines, helping prevent compression loss and abnormal noise.
