Kompact EM Series to Suit the BMW N20 & N26 Engine

The BMW N20 platform is a four cylinder inline turbocharged DOHC petrol engine produced from 2011 until 2017 and was a replacement for N52 and N53 Engines. The N20 produces between 115KW (154BHP) and 270 Nm (199 lb-ft) and 180 kW (241 bhp) and 350 Nm (258 lb-ft) depending on spec and vehicle it was fitted to, from an aluminium block and head combination including a single, twin-scroll turbocharger, double VANOS (variable valve timing) and a direct injection fuel system.

For several years now, OE manufacturers have been using the diverter valve on the turbocharger system for more than compressor surge and, as such, found it helpful to electrify the once pneumatic valve. Traditional pneumatic valves required a pressure differential, caused by the closing of the throttle against boost pressure to activate the valve, whereas moving to an electronic valve meant opening up a host of virtually unlimited tuning and calibration options for the OE engineers to meet fine-tuned torque requirements as well as assisting with emissions and overall package efficiency.

This is where the Turbosmart Kompact EM Series of valves steps in. The Patented Kompact EM Valve technology means Turbosmart valves are electro-mechanical and, while fully integrating with the factory ECU and strategy, still provide the bullet-proof mechanical advantages and reliability of a piston-based, mechanical valve!
