Goal
Reduce fuel consumption and increase engine power by improving intake-air dynamics.
Problem
High fuel consumption and emissions of internal-combustion-engine vehicles.
Concept Summary
A specially designed air filter with a perforated case, internal diffuser, cone and fins that swirl, pre-cool and accelerate incoming air before it mixes with fuel, resulting in more efficient combustion and lower fuel use.
Detailed Description
The filter consists of a perforated metal case that houses an internal diffuser and a cylindrical coupling to the engine intake manifold. A closing cap holds an internal cone whose outer surface carries multiple fins to create a swirling, high-velocity airflow. A cylindrical filtering element sits beneath the case. The geometry increases intake air speed, pre-cools the air, and improves the air-fuel mixture, leading to reported fuel-consumption reductions of 10-20 % and power gains of 8-10 % in tested vehicles.
