Toyota Dynamic Force engine
The Toyota's Dynamic Force engines are a petrol engine series developed by Toyota under the brand's New Global Architecture strategy.
Overview
The engine was developed as an engine that is claimed to achieve both driving performance and environmental performance, while pursuing high efficiency and low fuel consumption as well as having a direct feeling and smooth and pleasant acceleration performance.Specifically, the cylinder head and intake port design improves the tumble flow to increase the air intake volume--the majority of intake flow is now across that portion of the valve closest to cylinder centerline. Other methods include:
- Expansion of the valve clamping angle. The angle between intake and exhaust valve centerline is now 41 degrees--the previous design was 31 degrees.
- Hydraulically variable valve timing on both intake and exhaust camshafts.
- Very high compression moderated by Atkinson cycle.
- Longer bore and stroke ratio.
- Change of port end shape and expansion of seat inner diameter.
- Application of updated D-4S system to achieve "high-speed combustion", resulting in thermal efficiency over 40%.
- Cylinder centerline is offset from crankshaft centerline, meaning that piston top dead center is always equivalent to several degrees of crankshaft rotation.
Starting with the four-cylinder A25A type installed in XV70 series Camry in June 2017, the V6 V35A and four-cylinder M20A types have also appeared. On 16 October 2019, the three-cylinder M15A type, which would be installed in the XP210 series Yaris, was officially announced.
The Dynamic Force engines introduced an updated nomenclature system for Toyota engines and no longer employ the traditional iteration or generation of the engine followed by the one letter or two letter designation for the engine family and instead incorporate the engine's displacement in between a two letter code such as the M20A, with the "20" denoting a 2.0-litre engine.
