Supplier testing 3-cylinder engines with cylinder deactivation
Don't laugh just yet. According to Ward's Auto, Schaeffler has adapted its cylinder deactivation tech for inline-three engines. When less power is needed, the equipped threes would run with just two cylinders firing.
In some ways, the odd notion of cruising around with just an inline-two makes some sense. With the current technology, each group of valves to be deactivated needs its own roller finger followers (pictured above). While an automaker might need four sets of these components for a V8, it would only need one for an inline-three. That makes it a lot cheaper to implement.
The glaring problem with Schaeffler's design is that the gains from cylinder deactivation for such small engines aren't exactly huge. These aren't gas-guzzlers, after all. The company claims that the technology boosts economy by at least three percent – every little bit helps, though.
Autoblog reached out to Schaeffler for more information on the cylinder deactivation for inline-three engines, but the company had no comment "due to customer agreements."
