Accelerating Advanced Vehicle Research to expand Internal Combustion Ice Engine Market

Posted On February 03, 2021     

Advanced vehicles are taking over the market slowly and gradually. Now, the world is looking at ways to make these vehicles with ultra-low emissions and higher energy efficiency. To improve engines' thermal efficiency, it is essential to understand the interface that happens between the heat transfer process occurring by means of solid components and turbulent combustions occurring in the engine needs. Hence, there is a need for a research engine that would give engineers a unique view of the real time atomic-level workings that happen inside combustion engines.

Recently, a team of researchers has designed a purpose-built research engine at an industry-relevant scale so that it can be used in VULCAN. The VULCAN Instrument situated at the SNS was perfect for this research as it is specifically designed for residual stress, microstructure studies, deformation, texture, and phase transformation. It has the ability to house large structures.

 The development of an advanced combustion engine with the ability to operate in real-time is a significant advancement in the Internal Combustion Engine (ICE) Market. This is because the new engine is built exclusively to run inside a neutron beamline. It provides a special sample environment that permits the exploration of structural changes that happens in new alloys intended for an environment with high-temperature.

This new capability will enable researchers with experimental results that will help them to accurately and quickly vet materials—in turn, improving engine designs with high – fidelity computational models.

 As per the results of previous research works, the researchers' team optimized the importance of using non-destructive methods to analyze new materials and hence, used neutrons.  Neutrons are beneficial as they can penetrate even dense metals. When scattering off atoms, they present scientists with an abundant amount of structural information, complete to the atomic scale. For the current research, scientists used neutrons' ability to conclude how the alloys act in operating conditions like tension, extreme stress, and high heat, etc.-this helped them to identify even the smallest defects that would occur inside alloys.

The researchers stated that the new engine is based on a four-cylinder automotive engine with two liters. It has been modified to function with one cylinder. -This helps in conserving sample space in the beamline. The engine's platform can be made rotated across the axis of the cylinder, which gives it with maximum measurement flexibility. The engine itself is customized for carrying out neutron research, which includes the use of oil and fluorocarbon-based coolant.-This helps in providing better visibility into the combustion chamber.

The data collected from this new capability will help understand how temperatures of metal engine components change in the engine as per the course of the engine. Researchers are keen on creating a precise calculation of different phenomena like the evaporation of fuel, heat losses, and flame quenching, especially during cold-start engine operations when emissions are known to be the highest.

This new invention is expected to excite the general public as it helps produce state-of-the-art engine on an industrial scale. It will provide further options to users who seek to validate their existing models and resolve issues like temperature, stress, and strain. The new capability shows the direct value of neutrons to an important manufacturing sector, which is a huge development for the engine market.
