Internal Combustion Piston Engines TRIZ Cases

A partial exhaust flow reacts with fuel in a heating catalyst, using engine-state temperature estimation to stabilize aftertreatment heating.

Exhaust heat, electric cracking, and an expansion valve keep ammonia gaseous to deliver stable on-board hydrogen under varying engine conditions.

Inclined wedge blocks on the steering gear shell redirect rearward crash loads upward, reducing occupant injury risk in front-mounted layouts.

A top-mounted siphon line reaches the tank bottom to drain DEF without removing components, cutting service complexity and extra parts.

A pilot subchamber and single dual-fuel injector stabilize lean rotary engine combustion while reducing emissions from heavy-fuel use.

A converging-diverging injector duct accelerates hydrogen and draws in air through lateral ducts to improve mixing and combustion.

Multiple swirl chambers evaporate and mix urea spray in SCR exhaust flow to cut deposits, backpressure, and NOx unevenness.

3D AR guidance combines reinforcement learning and multi-physics simulation to improve fracture alignment and shorten surgery time.

FCN-LSTM prediction with reinforcement learning detects walking, stopping, and running at intersections for real-time hazard warning.

A segmented pre-combustion chamber purges exhaust residuals into a storage chamber to maintain ignition at low load and retarded timing.

Traffic weight coefficients normalize delay, stopping, and congestion indexes across lanes, intersections, zones, and whole road networks.
