In layman's terms, Pressure Scanners is a device that can measure fluid pressure under specific operating conditions.
It can be used to monitor the pressure state of the gas in the system and further optimize the performance.
1. Role of Pressure Scanners in Engine Systems
Optimize engine performance and emissions:
Function: Pressure Scanners are widely used to measure the pressure of key parts of the engine synchronously at multiple points on the engine test bench and prototype vehicles.
Example of application:
In-cylinder pressure: Measures the pressure change in the combustion chamber, which is a core parameter for studying the combustion process, calculating indicated power, analyzing knock, and optimizing ignition timing and injection strategy.
Intake line/manifold pressure: Intake flow and pressure fluctuations are monitored for optimization of turbocharger performance, variable valve timing systems, assessment of intake efficiency.
Advantages: Simultaneous measurement of multi-point pressure can accurately capture the dynamic interaction and pressure fluctuations between various systems under different engine conditions (such as rapid acceleration, high load, idle speed), in order to optimize combustion efficiency, improve power output, reduce fuel consumption and meet Strict emission regulations provide key data support.
2. Improve aerodynamic performance and thermal management
Function: Pressure Scanners are used to finely map the pressure distribution of the body surface, internal flow channel and heat dissipation system in wind tunnel tests, real vehicle road tests and thermal management tests.
Example of application:
Pressure distribution on the surface of the car body: densely arrange measurement points in the wind tunnel model or the real car to simultaneously measure the pressure generated by the airflow flowing through various parts of the car body (such as the front bumper, A-pillar, rearview mirror, roof, and rear). It is used to evaluate aerodynamic drag, lift, lateral force, wind noise sources, optimize styling design to reduce drag coefficient (increase cruising range/fuel economy) and improve high-speed stability.
3. The role of flow field measurement and control
With the continuous development of automotive technology, flow field measurement and control technology is more and more widely used in engine development. Flow field measurement and control is not limited to the precise control of the airflow, but also involves the real-time monitoring and regulation of the pressure, temperature and flow of the fluid in the entire vehicle system. Pressure Scanners provides important support for flow field measurement and control.
By applying Pressure Scanners in different systems, the R&D team can obtain more accurate fluid pressure data. For example, in the engine combustion chamber, the distribution and speed of the airflow directly affect the combustion efficiency. Pressure Scanners can provide real-time airflow pressure regulation under different working conditions, helping engineers optimize airflow paths and improve combustion efficiency, so as to achieve better power output and fuel economy.
In general, the role of Pressure Scanners in automotive research and development is far more than simple pressure regulation. As a part of flow field measurement and control technology, it plays an important role in optimizing engine performance, improving fuel efficiency, reducing emissions and enhancing vehicle safety.
