Solution Overview
Problem
Existing powertrains struggle to minimize the impact of emissions, particularly criteria pollutants like soot and NOx, which vary by location and time, requiring a dynamic control system to adjust pollutant ratios and reduce environmental health risks.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the engine operates to minimize fuel consumption, then energy efficiency is improved, but pollutant emissions (soot, NOx) increase
Solution Approach 1:
The system dynamically adjusts engine operating conditions and powertrain configuration based on real-time location data, time of day, and environmental conditions. The control system continuously optimizes the balance between fuel efficiency and emissions by selecting appropriate operating modes (e.g., electric-only, hybrid, or combustion) and adjusting engine parameters such as injection timing and air-fuel ratio according to the specific environmental context.
Solution Approach 2:
The system changes key operating parameters including power distribution between motor and engine, engine load, injection timing, and air-fuel mixture composition based on location-specific environmental conditions. These parameter adjustments allow the system to shift between minimizing fuel consumption and minimizing harmful emissions depending on the operational context.
2Object-affected harmful factors
If the system reduces harmful pollutants in high-population areas, then environmental health impact is improved, but system complexity increases
Solution Approach 1:
The control system integrates multiple functions including location-based environmental assessment, real-time emissions monitoring, powertrain optimization, and aftertreatment control into a single unified system. This multi-functional approach manages complexity by consolidating control logic rather than requiring separate systems for each function.
Solution Approach 2:
The system continuously monitors emissions data, location information, and operational parameters, then uses this feedback to dynamically adjust powertrain control strategies. The feedback loop enables the system to adapt to changing environmental conditions and optimize emissions reduction effectiveness without requiring manual intervention or overly complex pre-programming.
3Object-generated harmful factors
If the aftertreatment system is activated to reduce pollutant concentrations, then emissions are reduced, but energy consumption increases
Solution Approach 1:
The system activates the aftertreatment system in advance before the vehicle enters high-population or environmentally sensitive areas. By pre-heating catalysts and preparing emission control components, the system ensures immediate emissions reduction capability upon entering sensitive zones without requiring excessive energy input during actual operation in those areas.
Solution Approach 2:
The aftertreatment system operates periodically or intermittently based on location and environmental conditions rather than continuously. The control system activates emission reduction measures only when the vehicle is in or approaching areas where pollutant reduction provides maximum benefit, thereby minimizing unnecessary energy consumption while maintaining effective emissions control.

AI summary
A powertrain control unit may be configured to control an engine and identify a first operating condition is expected to fulfill a demand for output with an exhaust stream having a first amount of a pollutant (e.g., NOx, particulate matter), and a second operating condition expected to fulfill the demand with an exhaust stream having a reduced amount of the pollutant as compared to the first amount. The powertrain control unit may receive duty cycle information to control the engine to fulfill the demand per the second operating condition, yielding the reduced amount of pollutant in the exhaust. Duty cycle information may include speed, location, position, rotation, temperature, and/or other information. A vehicle, backhoe, bulldozer, crane, and/or combine harvester may comprise the powertrain control unit and an engine and aftertreatment system. An exhaust aftertreatment system may be remotely activated, which may reduce warmup time associated with emissions mitigation.
