Casings TRIZ Cases
- Variable Intake Valve Actuation Sub-units for Modular Engine Maintenance
Segmenting variable intake valve actuation into independent sub-units reduces maintenance time and cost by isolating faulty solenoid valves.
- Oil-Cooled Cylinder Block with Gravity Drain for Rapid Warm-Up
Gravity-driven discharge reduces oil in the coolant jacket, enabling rapid engine warm-up and lower friction losses.
- Fuel Rail Mounting Isolation for Engine Vibration Stress
An isolation member between the fuel rail and cam cover absorbs vibrations, reducing stress on fuel lines caused by hydraulic loads.
- Crankcase Bracket Simplifies Oil Passage Routing
A crankcase bracket consolidates oil filter and cooler connections, reducing passage complexity and manufacturing steps.
- Piston Through Holes for Combustion Chamber Cooling
A piston with peripheral through holes channels scavenging gas to cool the crown portion during the scavenging stroke.
- Engine Auxiliary Combustion Chamber Asymmetric Piston Wall
An engine uses an asymmetric piston partition wall to guide fuel into an auxiliary combustion chamber for ignition.
- Engine Cylinder Breather Chamber Integration for Rigidity
Integrates a breather chamber into the cylinder peripheral wall to separate oil mist, reinforcing structural rigidity without increasing engine weight.
- Centrifugal Mass Balancer with Roller Disks for Engine Vibration Control
A centrifugal mass arrangement uses roller disks rolling against the inner housing wall to balance rotational accelerations in reciprocating-piston engines.
- Engine Oil Guide System for Filter Leak Management
A guide structure channels lubricating oil along the engine case sidewall to a collecting portion.
- Inverted Non-Return Valve for Crankcase Oil Separation
A non-return valve uses gravity to hold the body open without preload, allowing free oil discharge through the return line.
