Engine developers employ revised electronic architectures, mechanical tweaks to boost fuel efficiency and performance of internal-combustion engines.

Engineers are leaving no stone unturned in their unceasing drive to improve fuel economy, leveraging electronics, monitoring airflow and using data from outside the vehicle. Computer architectures are being revised to simplify controls and reduce sensor counts, helping keep costs in line.

Mechanical upgrades continue, but electronics are the key tool for engine design teams attempting to do more while using less fuel. Computers constantly monitor and control the engine, transmission, after-treatment systems and more. Powerful control processors analyze huge volumes of data used to adjust engine operations in real time.
