IC Engine Locomotives TRIZ Cases

Dual lithium-ion batteries with control chassis and HMI improve locomotive monitoring, switching, and reliable diesel engine starting.

During coasting or braking, the traction motor recharges a primary battery that powers auxiliary locomotive loads and frees diesel horsepower for propulsion.

A corrugated or coiled hydrogen hose bridges vehicle parts, handling cornering and length changes while maintaining safe, fatigue-resistant gas transport.

Integrated main-deck fuel compartments store pressurized gaseous fuel tanks in structural wells, increasing capacity without sacrificing locomotive space.

An AI model learns baseline and field train data to predict fuel consumption despite changing locomotive operations.

Segmenting the power unit and fuel tank reduces explosion hazards while maintaining balanced axial loads for operational stability.

Asymmetric recesses in side members reduce mass while a load-bearing sheath raises vertical flexion frequency above 6.5 Hz to decouple bogie vibrations.

A rail vehicle cooler assembly uses a bypass suction system to actively remove separated impurities from the collection box.

Networked sensors transmit adhesion levels to controllers that dynamically adjust power delivery, reducing fuel consumption from wheel slippage.

A flexible joint transfers load from the locomotive underframe to the car body cant rail via diagonally situated members.

A ventilating duct connects a side cover opening to a totally enclosed motor suction inlet for external air supply.

Segmented fuel gas storage modules replace heavy fixed tanks, enabling dynamic weight distribution across axles and reducing overall fuel consumption.

Segmented twin-unit locomotive isolates heavy cryogenic storage to reduce explosion hazards and shorten refueling idle time.

Segmenting equipment into groups positions high-maintenance modules near the offset corridor, reducing maintenance duration while preserving lateral space.

Standardized mounting interfaces connect diverse locomotive drive units to a single vehicle structure.

A segmented locomotive slug unit adds traction motors to boost pulling force while maintaining tight turning radii.

Auxiliary power unit manages gaseous fuel delivery to resolve signal integrity issues across railcar chassis.

A segmented fuel storage system concentrates bulk capacity in a primary railcar tank while supplying a smaller buffer unit via an intermediary device.

Locomotive communication system transmits operational data to tender cars.

An auxiliary diesel engine powers the generator during operational breaks, reducing main drive wear and noise while maintaining electrical supply.

A railway truck frame uses planar arm members to transfer tractive and lateral forces while minimizing vertical force transmission.

Welded frame sections resolve high production costs and limited spring length by segmenting cast steel components into cost-effective assemblies.

A rail vehicle relocates the operator cab to a lead unit and installs fuel tanks in the vacated space.

A tender car motor converts wheel rotation into electric power to drive a fuel pump, reducing the energy burden on the main engine.

Flexible bellows connect a hollow bolster to traction motors, preventing air leakage during relative movement and ensuring consistent cooling.

Routing exhaust pipes through the underframe bolster preserves interior compartment space and suppresses noise propagation.

Air blowers channel cooling air to wire gutters, preventing overheating and insulation deterioration in tight underfloor spaces.

A locomotive fuel tank system uses a separable second tank to adjust axle load distribution dynamically.

Asymmetric motor placement and counterbalancing links eliminate opposing reaction forces that cause frame pitching and unequal axle loads.

Centralizing the blower reduces component count and maintenance complexity while an elevated inlet prevents debris contamination of the cooling airflow.

A rail vehicle cooling circuit uses a heat exchanger to dissipate traction system thermal energy into the onboard extinguishing agent.
