Electrical Control TRIZ Cases
- Evaporated Fuel Treatment Device Pressure Control
A control device monitors fuel tank inner pressure to adjust closing valve speed for safe vapor passage flow.
- Exhaust Gas Temperature Control via Dual-Mode Post-Injection
Dual-mode post-injection adjusts fuel rate and duration to target specific exhaust gas temperatures for catalyst regeneration.
- Diesel Engine NH3 Sensor Control for Low-Pressure EGR
A diesel engine control system measures ammonia concentration downstream of the SCR filter to adjust low-pressure exhaust gas recirculation rates.
- Dual Fuel Engine In-Cylinder Temperature Control
Adjusts first fuel injection based on expected in-cylinder temperature progression to resolve ignition reliability and temperature control precision trade-offs.
- Dual Turbocharger Control for Engine Transient Response
Segmenting turbine inertia resolves the power versus torque response trade-off while arbitration logic manages compressor surge limits.
- Variable Compression Ratio Engine via Phasing Device
A variable compression ratio engine uses a phasing device to adjust piston stroke length.
- CVT Shift Speed Control via Engine Torque Adjustment
A vehicle control apparatus calculates an upper-limit shift speed for a continuously variable transmission based on allowable inertia torque.
- Intelligent Variable Mode Control for Diesel Turbocharging
Dynamic mode selection and genetic algorithm optimization recover diesel engine output power and optimize fuel consumption under variable altitude conditions.
- Ignition Control System Adaptive Calibration for Spark Plug Wear
Dynamic ignition calibration minimizes electrode wear by stepwise reducing energy until misfire detection, extending spark plug life beyond 100,000 km.
- Engine Start Fuel Injection Control via Friction Torque Gradient
Corrects reference gradients with friction torque changes to reduce unburnt hydrocarbon emissions and black smoke.
- Air-Fuel Ratio Control Device Feedback Precision Management
A control device extends feedback operation after sensor detection precision deteriorates to maintain measurement accuracy.
- SCR Catalyst Recharging via Exhaust Gas Temperature Control
Raising exhaust gas temperature enables urea thermal decomposition, preventing deposit formation while maintaining ammonia levels on the SCR catalyst.
- Pretreated Gasoline Particulate Filters for Rapid Cake Filtration
Pretreating gasoline particulate filter pores with dopants establishes immediate cake filtration layers.
