High-Efficiency Operation of a Compression Ignition Engine for Heavy-Duty Truck Applications
Many high efficiency combustion concepts leverage a combustion process that is controlled by chemical kinetics rather than by a typical trigger such as a spark or a fuel injection. In collaboration with Argonne National Laboratory, the AECL has been studying the dynamics of this type of combustion mode and has been investigating methods of controlling combustion timing using inexpensive sensors that are more readily available on production vehicles.
High Pressure Fast Response Direct Injection System for Liquified Gas Fuels Use in Light-Duty Engines
One way to improve internal combustion engines is to utilize them in conjunction with a more carbon neutral fuel. The AECL is partnering with WM International and Hyundai to examine high efficiency use of dimethyl ether and propane fuels enabled through a unique high pressure fuel injection system.
Evaluation of Energy Efficient Mobility Systems
Connected and automated vehicle systems can improve transportation safety and energy efficiency. However, the ability to optimize energy use in real-world applications is challenging to assess. In collaboration with Argonne National Laboratory, the AECL is examining the uncertainty and repeatability of connected and automated vehicle operations.

Enabling Efficient Fuel Cell Control
Fuel cells provide a method of electrifying vehicles that is well suited to medium and heavy-duty vehicles, but the highly variable power demands typical of automotive applications make proper control of the dynamics of a fuel cell stack challenging. The AECL is investigating new methods to ensure that internal variations in fuel or air flow, temperature, and humidity can regulated to ensure sustained performance and optimized longevity.
