Cylinder Heads TRIZ Cases
- Cylinder Cover Port Sealing With Laser Overlay Corrosion Control
Laser metal deposition on cylinder cover port sealing regions limits alloy dilution, prevents corrosion, and preserves fatigue strength.
- Oval Cylinder Bore Geometry to Reduce Piston Abrasion
An oval cylinder bore cuts piston contact area while preserving the upper-cylinder oil film to reduce abrasion and seizure.
- Double-Arrow Crab Plate Layout to Reduce Cylinder Head Cracking
Protruding contact pads on a double-arrow crab plate localize clamping loads away from coolant passages to reduce cylinder head fatigue and cracks.
- Cylinder Liner Gasket Structure for Wear and Leakage Control
A variable-thickness cylinder liner gasket evens interface pressure to cut wear, leakage, and deformation at the strongback joint.
- Solenoid-Wedge Engine Brake for Hydraulic-Free Valve Holding
A solenoid-driven wedge and pin hold exhaust valves open for engine braking, replacing complex hydraulics with simpler, more reliable actuation.
- Cylinder Head Sealing Sleeve for Durable Combustion Chamber Sealing
A tapered sealing sleeve uses plastic deformation to maintain clamping force and prevent combustion chamber leakage over engine life.
- Fuel Injector Sleeve Sealing Ridge for Eroded Cylinder Heads
A radially outward sealing ridge creates line contact beyond eroded clamping surfaces, helping remanufactured engines prevent coolant leakage.
- Cylinder Liner Fire Ring Structure for Fatigue Crack Reduction
A stepped cylinder liner bore and recessed fire ring reduce pressure differences while improving stiffness and fatigue strength.
- Cylinder Liner Flow Balancer for Uniform Coolant Pressure
A liner-mounted flow balancer evens coolant flow and pressure in the water jacket, improving heat management and cylinder liner life.
