Combustion Engines TRIZ Cases

An oil discharge assembly uses a thrust collar and insert to create an annular drainage channel for pressurized oil collection.

Electrolyzer decomposes water into hydrogen and oxygen gases to resolve inconsistent fuel supply at low engine speeds.

Segmented pump housing allows disposable reservoir attachment to resolve trade-offs between ease of repair and connection complexity.

A swirl generating member on the nozzle plate creates localized vortices to reduce pressure differences across variable nozzle vanes.

A fuel injector spool valve rotates to direct flow through a curved rectangular outlet.

Plastic deformation of manifold pipe ends into reinforced connector openings eliminates weld spatters and contamination risks while ensuring gas-tight seals.

Segmented collector side walls distribute vibration stress across folded portions, preventing crack formation at box attachment points.

Positioning a piston pocket closer to a transfer window than a supply channel inlet prevents fuel contamination of scavenging air.

Rotating throttle bodies around bore axes resolves spatial conflicts between actuators and crankshaft to optimize air cleaner capacity.

Axial reinforcement means surround coupling regions on the disk body to reduce surface pressure and wear while minimizing moving parts.

Manifold quarter wave resonator eliminates third-order firing noise at high speeds without adding external components.

Welding the ground electrode to the metallic body before installing the threaded sleeve simplifies assembly and ensures precise electrode spacing.

Distinct bearing clearances reduce axis inclination and non-smooth movement in turbocharger nozzles.

A paired-piston linear engine uses a switched reluctance motor to convert reciprocating motion directly into electrical power.
