Įngine Control Units use the information transmitted by the sensor to control parameters such as ignition timing and fuel injection timing.
On such distributors, the timing advance is controlled electronically by the engine computer. Implements variable valve timing system VVT-iE and engine operation by Miller / Atkinson cycle. It is the first diesel engine from Toyota to use a rubber timing belt in conjunction with a SOHC head. The 4-cylinder engine also used a timing chain instead of a timing belt. The 2ZZ-GE was the first production engine to combine cam-phasing variable valve timing with dual-profile variable valve lift in the American market.ĢZZ - GE був першим серійним двигуном, який поєднував змінну фазу газорозподілу з подвійним профілем на американському ринку.Īlthough fitted with upgraded pistons, they still had the same ports, valve timing, and head gasket as the naturally aspirated 4A-GE engine, although T-VIS was omitted.
