Engine oil flow imaging
Nissan and the Japan Atomic Energy Agency (JAEA) have jointly developed a neutron imaging system that has provided the world’s first precise visualisation of oil flow in an engine operating at high speed.
Combining neutron radiography to visualise through lightweight metals with high-speed imaging technology, the imaging system gives researchers a chance to study the behaviour of lubricating oil as it circulates through an automobile engine or drivetrain. The images includes circulation and delivery of oil to each engine component, oil splash from the crankshaft, and oil delivery to the final drive gear.
JAEA and Nissan will conduct visualisation tests on engines to determine the causes of friction loss.
The study aims to redesign engines for optimal oil circulation with reduced friction leading to lower fuel consumption and C02 emissions.
