The 1NZ-FXE engine features a lightweight aluminum block and aluminum cylinder head with two overhead camshafts (DOHC) and four valves per cylinder (16 in total). Toyota described the 1NZ-FXE engine as having an “Atkinson cycle” since the compression stroke is shortened and the expansion stroke longer. The engine has a high physical compression ratio of 13.0:1, but the closing of the inlet valve is delayed, for an effective compression ratio of 9.5:1 Cylinder bore and piston stroke are 75.0 mm (2.95 in) and 84.7 mm (3.34 in), respectively.
