New KLEEMANN Kompressor for Mercedes-Benz V8 (M273)
 KLEEMANN introduces a new Kompressor system developed for the M273 V8 engine range fitted in the current 500/550 model ranges.
Like the Kompressor system for the outgoing V8 engine range (M113) the new design integrates the inlet manifold, intercooler and Kompressor in one integral unit. A compact design that ensures factory-like fit looks and quality.
KLEEMANN introduces the EMS (KLEEMANN Engine Management System)
Cutting edge engine management technology – Sporty engine characteristics
The anti-clockwise rotating Roots type Kompressor is characterized by its unique ability to develop plenty of power at low boost pressure and this type of supercharger has proved its reliability and efficiency for many years. The new electronically controlled fuel injection and management system KLEEMANN EMS is on the other hand a technological break through.
The fuel injection and management system allows boost pressure to vary from 0,3 bar to 0,70 bar as the engine rotates up the rev scale. The varying boost pressure ensures progressive and sporty engine characteristics known from naturally aspirated high performance engines. Increase in rpm results increase in increased power output all the way to up to the rev limiter. Furthermore the system ensures an effect curve without any bumps or valleys.
The EMS reduces boost pressure thus power output a fraction of a second before gearshifts to ensure smooth and gentle shifts.
Punch from idle - Flat torque curve remains intact
Like the earlier generations of KLEEMANN Kompressor solutions the new system still ensures plenty of torque from low revs thus a car fitted with the new system will have plenty of punch from rev levels just above idle. 90% of torque is present at 2000 rpm.
Safe, durable, reliable
The low boost pressure of just 0,30 – 0,70 bar makes the system safe and provides long-term durability for the engine. To further improve the safety aspect the EMS features a safety mode constantly monitoring the fuel - boost pressure ratio ensuring that the engine cannot run lean thus suffer damage to the engine. In other words the boost pressure and amount of fuel injected to the engine will always comply.
Even if the car is driven in an area of high altitude (less oxygen, low pressure) and down to sea level boost pressure and fuel supply adjusts automatically to protect the engine from running lean.
