![]() The engine runs with a 13:1 compression ratio for gasoline-only and 14:1 for a hybrid system. The current average for four-cylinder engine thermal efficiency is about 36.8 per cent. Toyota is showcasing this new engine as its illustration of TNGA. The first engine in this new architecture is a 2.5-liter four-cylinder that achieves 40 per cent thermal efficiency as a gasoline-only engine, and 41 per cent when used in a hybrid system. The new TNGA engines are called "Dynamic Force Engines" and combine loss reduction (lower energy losses), improved fuel combustion, and improved air intake efficiency. The company is targeting 10 per cent better power performance (measured by vehicle 0-60 mph/0-92 km/h times) and 20 per cent better fuel economy. ![]() The modular design of the TNGA engines and transmissions allows for the mixture of versions that Toyota will be rolling out over the next few years. Ride height, hood angles, drivetrain weights, and more are all aspects of improving the efficiency of the automobile. With TNGA, Toyota is changing the car almost fundamentally, to aid every aspect of efficiency, it says. These will be combined with new electrified components for 10 versions of six new hybrid-electric drive systems in that timeframe. Toyota will introduce 17 versions of nine new engines and 10 versions of four transmissions from 2017 to 2021. The company says that the recently-developed, more efficient engines will begin rolling out in 2017. Toyota Dynamic Force Engine uses water cooling technology, whereas some Skyactiv engines use air and water cooling technology.Toyota has unveiled new engines based on its Toyota New Global Architecture (TNGA), to be used in both standard gasoline and hybrid vehicles.On the other hand, Skyactiv engines are divided into Skyactiv-D (diesel), Skyactiv-G (gasoline), and Skyactiv-X (petrol). There are mainly three types of fuel engines under Toyota Dynamic Force Engine- M20A-FKS (petrol), M20A-FXS (petrol-hybrid), and M20A-FKB (petrol flex fuel).Toyota Dynamic Force Engine was invented in 2017, but Mazda’s Skyactiv was developed earlier in 2011.Toyota Dynamic Force Engine is a product of Toyota on the other hand, Skyactiv is a product of Mazda.Skyactiv, on the other hand, refers to a technology developed by Mazda which can be seen throughout the vehicle. Toyota Dynamic Force Engine refers to the series of engines developed by Toyota and designed with efficiency, power, and torque in mind.Main Differences Between Toyota Dynamic Force Engine and Skyactiv The advanced control modules of Skyactiv transmissions help to achieve responsiveness, efficiency, and precision. It uses ultra-high-tensile steel, making it lightweight but more robust and stiffer in critical areas. The vehicle architecture of Skyactiv is designed to create stability at high speeds and nimbleness at low rates. The company designs this engine series to improve combustion speed and minimize energy losses. Toyota’s advanced internal combustion technology and the Dynamic Force Engine provide top-class thermal efficiency. Dynamic Force Engine was designed as an engine that can provide both environmental and driving performance while pursuing low fuel consumption and high efficiency and having a pleasant and smooth acceleration performance. In 2017 Toyota started to produce its Dynamic Force Engine under the TNGA (Toyota New Global Architecture). Water and air cooling techniques are used in Skyactiv engines. Skyactiv-D (diesel), Skyactiv-G (gasoline), and Skyactiv-X (petrol). Brand Toyota Mazda Invention 2017 2011 Fuel type M20A-FKS (petrol), M20A-FXS (petrol hybrid), M20A-FKB (petrol flex fuel). Skyactiv refers to a technology developed by Mazda which can be seen throughout the vehicle.
