The New 2.4-Liter Slant Engine, 2TZ-FE, for the Toyota Previa 901717

This paper describes a new 2.4-liter 16-valve in-line four-cylinder engine, 2TZ-FE, which has been mounted horizontally on a new minivan, the TOYOTA PREVIA. This engine has the TOYOTA original compact 4-valve DOHC system (scissors gear mechanism), and TOYOTA's newest technologies, such as 75 deg. slant cylinder and Separated accessory Drive System. The compact configuration reduces the height of this engine to only 44Omm (17.3-inches). Engine location is under the flat floor on the midship rear-wheel-drive vehicle and allows the PREVIA to have a spacious cabin with walkthrough.

Its high performance, 103kW at 500Orpm and 209Nm at 4000rpm, has been achieved through updated technologies, such as: Knock Controll System (KCS), well studied intake system and exhaust manifold which is made of stainless steel double pipe.

At the same time, high reliability and quietness have been achieved for the 2TZ-FE by TOYOTA's updated technologies.
