Casings TRIZ Cases

Segmented stamped parts joined by welding provide rigidity without casting costs.

Merging separator and nozzle into the cover body resolves complexity trade-offs while maintaining compact engine design.

A vaned rotor generates negative pressure to drive cooling airflow through a dedicated housing passage toward the engine oil seal.

Engine side rib guides cooling water pump drainage downward, eliminating enlarged cover members and improving shape flexibility.

A bearing structure guides lubricating oil from an in-block gallery through main and control shaft bearing metals to supply both crankshaft and control shaft parts.

A longitudinal locking rod prevents axial micro-displacements of the drive shaft to reduce false Brinell wear during transport.

A quantitative one-way oil gas lubricant system uses specific orifice diameters to control lubricant flow in a 4-stroke engine.

Integrating microchannels into a polymeric composite engine housing enables active heating and cooling, resolving weight versus durability trade-offs.

A crankcase separating wall with variable thickness increases internal volume to reduce friction resistance in multi-cylinder engines.

Integrating air introduction passages into the cylinder block simplifies manufacturing and facilitates casting burr removal.

Perpendicular fasteners isolate central crankshaft torque from split crankcase halves, preventing structural stress during high-power operation.

Positioning the piston ring below the crankcase reduces bolt length and engine weight without compromising connection strength.

Segmented front and rear brackets with turnbuckle alignment allow quick engine replacement, reducing downtime in remote power generation sites.
