Compressor Load Control for Engine Speed and Fuel Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prime movers in work vehicle service packs often overload, leading to reduced fuel efficiency, increased noise, and pollutant emissions due to limited operating speeds and constant high-speed operation to meet pneumatic loads.
Innovation Solution
A load control system that monitors air compressor loads and adjusts the prime mover's speed to maintain low noise and maximize fuel efficiency by operating at lower speeds when loads are low and increasing speed only as needed to prevent pressure drops below a minimum setting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the prime mover operates at higher discrete operating speeds to meet pneumatic loads, then the air compressor can deliver sufficient air, but fuel consumption increases and noise increases
Solution Approach 1:
The system dynamically adjusts the prime mover operating speed based on real-time air compressor load requirements. Instead of operating at fixed high speeds, the controller continuously monitors pressure differential across the air compressor and adjusts speed to match actual demand, enabling the prime mover to operate at lower speeds when full air delivery capacity is not required.
Solution Approach 2:
The system changes the operating parameters of the prime mover by adjusting speed based on load conditions. The controller modifies speed parameters within the range of available discrete speeds, selecting optimal speeds that balance air delivery requirements with fuel efficiency, rather than maintaining constant high-speed operation.

3Reliability
If the prime mover operates at the highest discrete operating speed continuously, then pneumatic loads are always met, but fuel efficiency decreases
Solution Approach 1:
The system implements feedback control by continuously monitoring the pressure differential across the air compressor and using this information to adjust prime mover speed. The controller receives feedback on actual load conditions and modifies operating parameters accordingly, ensuring the prime mover operates at the lowest necessary speed to meet demand while maintaining fuel efficiency.
Solution Approach 2:
The system dynamically adjusts the prime mover operating speed based on real-time air compressor load requirements. Instead of operating at fixed high speeds, the controller continuously monitors pressure differential across the air compressor and adjusts speed to match actual demand, enabling the prime mover to operate at lower speeds when full air delivery capacity is not required.
4Use of energy by moving object
If the prime mover operates at lower operating speeds, then fuel consumption decreases, but the ability to meet high pneumatic loads is reduced
Solution Approach 1:
The system dynamically adjusts the prime mover operating speed based on real-time air compressor load requirements. When high air delivery capacity is needed, the system automatically increases speed to meet demand. When loads are lower, the system reduces speed to optimize fuel efficiency, thus adapting to varying productivity requirements.
Solution Approach 2:
The system changes the operating parameters of the prime mover by adjusting speed based on load conditions. The controller modifies speed parameters within the range of available discrete speeds, selecting optimal speeds that balance air delivery requirements with fuel efficiency, rather than maintaining constant high-speed operation.

AI summary
A load control system, in certain aspects, may be configured to decrease the amount of noise pollution of a prime mover (e.g., engine) of a service pack in that it may not require the prime mover to operate at higher discrete operating speeds to deliver small amounts of air from the air compressor. The load control system may also only increase the speed of the prime mover to a minimum discrete speed required, keeping noise at a minimum. The load control system may also maximize fuel efficiency by not operating the prime mover at the highest discrete speed at all times. More specifically, the lower operating speeds may lead to less fuel consumption.
