Influence of Engine Electronic Management Fault Simulation on Vehicle Operation

Area of Science:

• Automotive Engineering
• Engine Management Systems
• Environmental Science

Background:

• Modern internal combustion engines rely heavily on electronic control for optimal fuel mixture preparation.
• Failures in electronic engine components can compromise vehicle performance, driving safety, and emissions control.

Purpose of the Study:

• To investigate the impact of electronic engine system failures on vehicle operating characteristics.
• To quantify the effects of simulated sensor and actuator failures on vehicle performance and exhaust emissions.

Main Methods:

• Simulated eight distinct electronic system failures (sensors and actuators) on a petrol internal combustion engine vehicle.
• Conducted laboratory measurements to compare operating characteristics between faulty and fault-free states.
• Determined vehicle performance parameters and selected exhaust emission components under various operating conditions.

Main Results:

• Electronic component failures can significantly alter vehicle operating characteristics.
• Some electronic failures negatively impact performance and emissions without being noticeable to the driver.
• Quantified changes in vehicle performance and exhaust emissions due to specific electronic failures.

Conclusions:

• Electronic system failures pose a risk to road safety and environmental compliance.
• Findings can inform vehicle legislation, manufacturing standards, and emissions modeling.
• Highlights the need for robust diagnostic systems to detect subtle electronic failures.
