Photoacoustic Soot Measurement System for Cleaner Engines

Published Patent Application Number: PCT/US2024/046755

Problem

Soot accumulation in engines can reduce efficiency, increase emissions, and cause mechanical failures. Traditional measurement methods are often slow, inaccurate, or require invasive procedures. This invention offers a non-invasive, real-time monitoring solution that helps optimize engine performance. It enables early detection of excessive soot buildup, preventing costly repairs and environmental harm. By improving soot measurement, it contributes to cleaner and more efficient combustion systems.

Invention

This invention introduces a photoacoustic measurement system that detects soot deposition in engines. It works by irradiating soot deposits with pulsed electromagnetic radiation, causing rapid expansion that generates an acoustic pressure wave. The system then senses the pressure wave using an acoustic measurement device. By analyzing the signal and calibration data, it determines the amount of soot deposited. This method provides a precise and efficient way to monitor soot buildup in real time.

Potential Commercial Applications

This technology can be used in automotive, aerospace, and industrial engine systems. It is valuable for vehicle manufacturers aiming to meet stricter emissions regulations. Power plants and factories can integrate it into combustion monitoring systems to enhance efficiency. It may also be useful in scientific research and environmental monitoring. Additionally, it could be adapted for predictive maintenance in fleet management.

Competitive Advantage

Lower Maintenance & Downtime: Prevents buildup, reducing engine failures and costly servicing.
Boosted Fuel Efficiency: Optimizes combustion to cut fuel costs for fleets and manufacturers.
Regulatory Compliance Made Easy: Helps meet emissions standards, avoiding fines and upgrade expenses.
Fast, Cost-Effective Integration: Simple deployment without invasive equipment or high setup costs. 5. Scalable for Fleet & Industrial Use - Supports clean energy goals and opens new revenue opportunities.
