Toyota Develops World’s Most Thermally Efficient 2.0-Liter Petrol Engine

The biggest problem with the internal combustion engine is that most of the energy generated by combustion is wasted as heat rather than converted propulsion for the vehicle.

The Toyota’s new Dynamic Force Engine has made a breakthrough in thermal efficiency in being 40% as a conventional engine and 41% efficient in hybrid form. Most internal combustion engines are only 20 percent thermally efficient.

In addition to heat, the various systems required to run the engine all take energy that could potentially be put to use propelling the vehicle.

In the Dynamic Force Engine, the sides of the pistons have been polished to a smooth mirror surface to reduce friction, with narrow grooves cross cut in it to improve scuff resistance.

The cylinder head has been designed with a high-efficiency intake port. A high-power ignition coil is used to burn every last droplet of gas from the multi-hole direct injector.

But Toyota didn’t just focus on efficiency and improved fuel economy. Another major benefit of this engine is its enhanced torque. Not only does it produce more torque than the modern equivalent 2.0-liter engine, it begins generating that torque at a lower engine rpm.

Toyota claims it will introduce 17 different versions of nine different engines, 10 versions of four transmissions and 10 versions of six hybrid systems by the end of 2021.

Toyota will start outfitting its vehicles with these new tech, but didn’t specify which models. Toyota said Europe, Japan, China and the US will all benefit from this new tech, and that it hopes to have these parts installed in 80% of new Toyota and Lexus vehicles by the end of 2023.

Do you think this new engine breakthrough from TOYOTA and that of Mazda will save the internal combustion engine i.e petrol and diesel cars?
