Mitsubishi's Compound Intake System Engine 850035

Mitsubishi Motors Corporation presents the newly-developed 2-liter engine, which we have named SIRIUS DASH. The SIRIUS DASH engine, with its compound intake system, features great performance in both high and low speed ranges while keeping fuel consumption low.
The compound intake system operates the 3 valves in 2 stages. When engine speed is low, just one intake valve is used, but when engine speed increases, two intake valves are used. And to make this engine truly extraordinary, we added a turbocharger with an intercooler, and equipped the whole thing with a total electonic control system.

Generally, high performance engines which have large inlet ports and high speed type valve timing enabling them to intake sufficient air for high performance at high speeds. The problem is here that when speed is dropped, combustion becomes unstable at the expense of torque and fuel consumption.
