Cylinder Heads TRIZ Cases
- Cylinder Liner Thermal Insulation for Friction Reduction
Segmented thermal insulation on the lower cylinder region maintains higher oil temperature, reducing hydrodynamic friction while preserving upper zone cooling.
- Cylinder Head Valve Insert Cooling Passage Design
Pre-machined valve seat inserts feature concentric cooling passages that surround the insert ring for direct thermal contact.
- Single-Cylinder Cylinder Head Asymmetric Mounting Holes
Non-equidistant mounting holes around the central injector recess resolve packaging restrictions that compromise inlet and outlet channel flow characteristics.
- Rough Cast Cylinder Liner Spine Geometry for Adhesion and Heat Transfer
Centrifugal casting creates variable spine density on roughened cylinder liners to resolve adhesion strength versus heat transfer efficiency trade-offs.
- Dual-Layer Cylinder Liner for High-Pressure Diesel Engines
A cylinder liner combines compact graphite iron and austempered ductile iron to optimize surface wear resistance and structural strength.
- Disposable Sleeve for Spark Plug Well Oil Sealing
Replacing failed permanent sealants, a disposable rubber sleeve prevents oil leaks and fire hazards by enabling quick installation without engine disassembly.
