What is Toyota Dynamic Force Engine?
In 2017 Toyota started to produce its Dynamic Force Engine under the TNGA (Toyota New Global Architecture). Dynamic Force Engine was designed as an engine that can provide both environmental performance and driving performance while pursuing low fuel consumption and high efficiency as well as having a pleasant and smooth acceleration performance.
Along with the advanced internal combustion technology of Toyota, Dynamic Force Engine provides a top-class thermal efficiency. This series of engines are designed by the company for improving combustion speed and minimizing energy losses.
Motors of the engine have a longer than a traditional conventional engine stroke and a higher compression ratio to improve thermal efficiency.
A combined fuel injection system named D-4S is employed in this engine for optimizing combustion. D-4S injection system uses both port and direct injection and controls fuel injectors for best fuel economy, lowest emissions, and best performance, depending on the engine mode.
Dynamic Force Engine of Toyota uses a Variable Control System for effectively optimizing and managing combustion while minimizing energy losses.
A variable cooling system, with an electric water pump, flow shutting vales, and an electronically controlled thermostat, is used for thermal management of the engine. The amount of coolant flowing to the engine, cabin heater core, radiator, and transmission oil cooler is intelligently controlled by the system for delivering a faster engine, transmission, and cabin warm up or cooling depending on the situation.
What is Skyactiv?
Skyactiv refers to a series of technologies developed by Mazda which includes improved transmissions, engines, chassis, and the vehicle body that bring safety, substantial fuel economy, and other many benefits to the cars developed by Mazda. Skyactiv includes innovative engines for the lightweight vehicle structure.
There are three main areas of Skyactiv technology. First of all, this technology enables Mazda engines to be more efficient.
Its new engine has a 14:1 compression ratio which is the lowest mass-produced diesel engine in the world. It helps in reducing CO2 emission by 20% and boosts fuel economy by 20%.
There are mainly three types of engines under Mazda’s Skyactiv. These are Skyactiv-X (petrol engines), Skyactiv-D (diesel engines), and Skyactiv-G (gasoline engines).
In Skyactiv engines, a cylinder-deactivation technology is used for building upon the fuel efficiency. This technology shuts down cylinders when the engine is in a state of minimal load, like while driving at a constant speed on the highway.
The vehicle architecture of Skyactiv is designed for creating stability at high speeds and nimbleness at low speeds. It uses ultra-high-tensile steel for making it lightweight but stronger and stiffer in critical areas.
The advanced control modules of Skyactiv transmissions help to achieve responsiveness, efficiency, and precision.
