New 2.5-liter Direct-injection, Inline 4-cylinder Gasoline Engine

Toyota has named its new line of internal-combustion power plants "Dynamic Force Engines". To bring out the new engines' potential to the fullest, their basic structure was completely rethought using TNGA, and their overall structure and configuration were wholly innovated to achieve high-level driving and environmental performance. Work will continue to make the new engines even more advanced.

Achieves one of the world's best levels of both output and thermal efficiency^*

The new engines employ high-speed combustion technology and a variable control system. They also achieve greater thermal efficiency, resulting in high output, due to a reduction in energy losses associated with, among others, exhaust and cooling systems and the movement of mechanical parts. Their lineup includes a 2.5-liter engine that has one of the world's best thermal efficiencies^*―40 percent when used in gasoline-powered vehicles and 41 percent when used in hybrid vehicles (HVs). This new, thoroughly reconsidered and greatly evolved engine features numerous new technologies, such as technologies for minute control that make it highly responsive and allow it to generate ample torque at all speeds.

Details of new technologies

High speed combustion technologyWorld's first

Both strengthened tumble flow and increased intake air volume are achieved by redesigning the longer stroke (Stroke/Bore≒1.2),widening the angle of the valve and the high efficiency intake port with laser-cladded valve seat. High speed combustion is achieved by these technologies.

Multi-hole direct injector

Strengthened tumble flow and high performance injector improved fuel air mixture, then high speed combustion is achieved.

Continuous variable capacity oil pump -Trochoid type-World's first

By controlling the oil flow rate under any engine running conditions, additional work is reduced, which then contributes to the reduction of engine friction losses.

Changing the oil pressure into the control chamber first, moving the oil pressure adjusting ring and outer rotor against inner rotor, then making the oil flow rate change continuously.
