New Digital Valvetrain Engine Gives Diesel Efficiency On Petrol Engines

The pursuit of low emissions is serious business. Companies are trying all sorts of engineering tricks to get rid of as much carbon dioxide and nitrogen oxides as they can.

A small engineering firm in the Midlands might have come up with an astounding solution, by ditching the camshaft altogether.

Camcon Auto has developed a fully electronic system it calls Intelligent Valve Actuation (IVA). In essence, an electronic control module sits on top of the engine and directly controls each valve with a rotary actuator.

With full electronic control over each individual valve, IVA can adjust any part of the engine’s airflow to the tiniest degree and at any time.

The net result is a reduction of emissions by up to 20 per cent, while also promising an improvement in power, driveability and performance. With infinite control over the engine timing, the IVA unit can provide exactly what the driver needs at any given time.

The IVA system has been designed so that it can fit onto existing conventional engines, eliminating the need for any expensive additional engine development, and could be on the market in as little as three years.
