Aeristech secures turbocharger funding

The investment round was led by Midven, who invested alongside Minerva Business Angels Network and members of OION. Aeristech will use the funding to progress testing programmes with two global vehicle manufacturers.

Turbochargers are fitted to make an engine more powerful by using the energy from exhaust gases, which would otherwise be lost, to raise the pressure of air entering the engine. This also increases engine efficiency and materially enhances fuel consumption.

However, conventional turbochargers only assist the engine when sufficient exhaust-gas energy is available. Any mismatch between what the engine needs and what the turbocharger produces is known as ’turbo lag’.

Uniquely, Aeristech’s patented Hybrid Turbocharger Technology system (HTT) eliminates the turbo lag, allowing vehicles fitted with HTT to combust fuel far more effectively at lower revolutions than vehicles fitted with conventional turbochargers. As a result, the HTT system enables vehicle manufacturers to build smaller engines that give the same level of performance as larger engines and can generate 20 to 30 per cent in fuel savings.
