The application demonstrates its capabilities during vehicle operation, both in motion and idle, when fuel consumption occurs. The solution offers a plug-and-play approach to enhance fuel efficiency in internal combustion engine vehicles, which are prevalent on the road. The Air Intake Cooler (AIC®) system is particularly effective in urban environments and traffic congestion. The AIC® system optimises engine performance during idling and low-speed conditions, leading to significant pollution reduction and improved fuel efficiency.
