The 1UR-FE engine has 8 cylinders in a V-arrangement at a bank angle of 90° The 1UR-FE features die-cast aluminum cylinder block t with a five-bearings crankshaft and two aluminum heads with two camshafts (DOHC) and four valves per cylinder (32 in total). The Toyota 1UR-FE engine is equipped with L-type sequential fuel injection (SFI) system, Direct Ignition System (DIS) ignition system with individual coils on each spark plug, Acoustic Control Induction System (ACIS), Electronic Spark Advance (ESA) and ETCS-i (Electronic Throttle Control System-intelligent).
