Cylinder Heads TRIZ Cases
- Spark Plug Jacket Contact Surface for Coolant Cavity Sealing
An angled spark plug jacket contact surface increases sealing force after plug installation to prevent coolant cavity leakage.
- Dual-Protrusion Antipolishing Ring for Piston Deposit Removal
Dual protrusions scrape piston deposits on both upstroke and downstroke, reducing cylinder liner polishing and improving engine durability.
- Partial Cylinder Liner Structure for Lightweight Engine Recycling
A shortened cylinder liner with lower-end recesses and protrusions cuts weight while easing separation from the block for recycling.
- Uniblock Engine Layout With Dual Crankshafts for Higher Compression
A uniblock cylinder and head with dual external crankshafts raises compression, cuts gasket failures, and improves engine efficiency.
- Cylinder Liner Groove Structure for Lower Friction and Oil Control
Selective honed and recessed grooves in the cylinder liner cut ring friction in the stroke center while preserving oil consumption.
- Sloped-Flange Cylinder Liner for Fillet Fatigue and Oil Tightness
A sloped flange seat surface strengthens the fillet zone and improves liner-block sealing to cut stress concentration and oil leakage.
- Profiled Cylinder Liner Structure for Bore Distortion Control
Relief and stiffening features on a cylinder liner curb bore distortion from heat, assembly, and pressure, improving ring conformability.
- Uniblock Engine Structure for Leak-Free High-Compression Operation
A uniblock cylinder-block layout removes head gaskets and leak paths while supporting extreme compression ratios, lower emissions, and compact engines.
- Cylinder Liner Seal Bead Geometry for Multi-Location Sealing
Sinusoidal seal beads create multiple sealing locations on a cylinder liner, reducing leakage, friction, and seal pinch under tight space constraints.
- Cylinder Liner Flow Guide Structure for Uniform Engine Cooling
A protruding flow guide with axial openings redirects coolant to exhaust-valve hot spots, reducing stagnation and evening liner temperatures.
- Cylinder Head Roof Facets for Stable Lean-Burn Combustion
Machined roof facets in a lean-burn gasoline cylinder head drive omega swirl and tumble to widen stable combustion and improve fuel efficiency.
- Offset Chamfered Cylinder Ports for Valve Guide Bore Wear
Offset chamfered cylinder ports redirect gas flow around the valve to balance forces, reduce guide bore wear, and extend cylinder head life.
- Cylinder Head Valve Support Shaping for Accurate Valve Seats
By machining valve supports to a pre-compensated initial shape, the cylinder head reaches accurate valve seat geometry under operating loads.
- Cylinder Liner Aperture Alignment for Engine Port Sealing
Oblique aperture surfaces and an alignment tool position the cylinder liner to match engine ports, preserving flow and sealing during press-fit installation.
