Electrical Control TRIZ Cases

Forced upshift and intake air limiting keep the three-way catalyst within temperature limits while preserving vehicle speed and emissions.

A bypass orifice balances tank and canister pressure during purge, limiting fresh vapor draw while removing hoses and leak points.

Torque is limited after cold start until exhaust aftertreatment warms up, with the threshold adjusted to vehicle driving resistance.

Predictive downhill control preconditions exhaust aftertreatment temperature before an uphill segment, improving NOx reduction without extra fuel use.

Cold-start emission spikes are controlled by warning the driver and temporarily limiting engine power until exhaust aftertreatment reaches compliance.

An electronic Venturi throttle-mixer cuts leak points and replaces mechanical linkages for precise low-pressure gaseous fuel and air control.

Multiple hydrogen tanks and controlled valves match fuel pressure and flow to vehicle power demand, cutting throttling losses and emissions.

Using generator frequency instead of engine speed, this control approach keeps loop gain stable across operating points and reduces tuning effort.

Dual tank arrangements and controlled valves match hydrogen pressure to engine or fuel cell demand, cutting regulation losses and emissions.

Oxygen storage is integrated between air-fuel ratio switching and oxygen reversal points to avoid sensor-delay errors in catalyst diagnosis.

A unified generator set connection module replaces screw wiring with protected plug-in connectors to cut installation time and resist vibration.

Seat and neutral detection let an industrial vehicle stop engine output for safety, then restart steering-assist power when the driver returns.

Tank pressure changes and activation data let vehicles attribute fuel use across engine and auxiliary loads for better efficiency and maintenance.

Control logic uses exhaust geometry, filter fill status, and catalyst temperature to keep engine exhaust invisible while meeting emissions limits.

Dynamic gearbox and engine control keeps low-load operation in an optimal range to cut soot, fuel use, and anti-pollution blockage.

Real-time gear, engine speed, and braking control keeps EATS hot enough on downhill slopes while holding vehicle speed in range.

Electromagnetic rotor-stator actuation replaces bulky throttle linkages, enabling thin-profile, rapid, and precise air intake control.

Excess braking energy drives a hydrogen recirculation compressor, avoiding resistor heat load while storing useful pressure in the fuel system.

Excess braking energy is absorbed by pressurizing recirculated hydrogen, reducing waste and preserving heavy-duty fuel cell braking capacity.
