1. Overview The SQR484F is a 2.0L naturally aspirated gasoline engine from Chery’s ACTECO series, jointly developed with Austrian engineering firm AVL. Two versions were produced: early single intake VVT, and later upgraded DVVT (dual intake & exhaust variable valve timing), generally named SQR484F VVT in the market. Mass production and vehicle matching started around 2010, targeted at midsize sedans and compact family SUVs, positioned as a durable, low-cost maintenance NA powertrain. 2. Main Technical Parameters
