PARTICLE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18468357 titled 'PARTICLE SENSOR
Simplified Explanation
The particle sensor described in the patent application is designed to determine the concentration of soot in the exhaust gas of an internal combustion engine. It consists of a sensor housing, a sensor element fixed in the housing, and a protection tube fastened to the housing on the exhaust gas side. The protection tube includes an inner protection sleeve and an outer protection sleeve, creating an annular space between them. Both sleeves have gas outlets and gas inlets.
- Sensor housing with fixed sensor element
- Protection tube with inner and outer protection sleeves
- Annular space between inner and outer sleeves
- Gas outlets and gas inlets on both sleeves
Potential Applications
The technology can be used in automotive industries to monitor and control the emission of soot from internal combustion engines.
Problems Solved
1. Accurate measurement of soot concentration in exhaust gas 2. Protection of sensor element from harsh exhaust gas environment
Benefits
1. Improved engine efficiency 2. Reduced environmental impact 3. Enhanced engine performance
Potential Commercial Applications
"Particle Sensor for Soot Concentration in Exhaust Gas" can be used in automotive manufacturing for emission control systems.
Possible Prior Art
One possible prior art could be the use of similar particle sensors in exhaust systems of vehicles for monitoring different types of emissions.
Unanswered Questions
How does the sensor element withstand high temperatures in the exhaust gas environment?
The sensor element is likely made of heat-resistant materials to withstand the high temperatures in the exhaust gas environment.
What is the expected lifespan of the particle sensor?
The lifespan of the particle sensor would depend on factors such as usage conditions, maintenance, and the quality of materials used in its construction.
Original Abstract Submitted
A particle sensor for determining the concentration of soot in the exhaust gas of an internal combustion engine. The particle sensor includes a sleeve-shaped sensor housing, a sensor element fixed in the sensor housing and projecting beyond the sensor housing on the exhaust gas side, and a sleeve-shaped protection tube fastened to the sensor housing on the exhaust gas side, the protection tube including an inner protection sleeve and an outer protection sleeve, the inner protection sleeve surrounding an exhaust-gas-side end region of the sensor element, the outer protection sleeve surrounding the inner protection sleeve at least in some regions, so that an annular space is formed between the outer protection sleeve and inner protection sleeve. The outer protection sleeve and the inner protection sleeve each have a gas outlet and a gas inlet.
