The engine is twice as thermally efficient as most other internal combustion engines .

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. Toyota's new Dynamic Force Engine has made a breakthrough in thermal efficiency in being 40 percent efficient as a conventional engine and 41 percent efficient in hybrid form. Most internal combustion engines are only 20 percent thermally efficient, according to Green Car Reports.

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. This engine uses a new version of Toyota's D-4S direct injection system, which has already been used on the Toyota 86 and Subaru BRZ twins for years.

Toyota and Lexus Recall Vehicles for Fuel-Line Issues

  Toyota and Lexus Recall Vehicles for Fuel-Line Issues Toyota announced it is recalling 21,700 Toyota and Lexus cars in two separate recalls for problems with the fuel line that have the potential to cause a fire. Toyota is recalling roughly 11,800 of its 2018 Camry sedans because it’s possible that the fuel pipes and the fuel hoses in the engine compartment were not properly connected during assembly. This could lead to a fuel odor or leak, which—in the presence of an ignition source—could increase the risk of a fire.

The efficiency by which they do so is measured in terms of " thermal efficiency " www.msn.com/en-us/autos/news/ toyota - develops - worlds - most - thermally - efficient -20- liter - engine /ar-BBJLoZl?ocid=spartandhp&fullscreen=true#image=1.

Besides the obvious benefit of 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. Horsepower numbers make flashy headlines, but high torque at low rpm is extremely useful in real-world driving, getting you off the line more quickly and easily.

Toyota has not yet said in what vehicles we can expect to see this engine equipped in the future. A fair bet may be anything economy-minded that currently runs a similarly sized engine, such as the Corolla.

This 750-HP LS7 Crate Engine From Mercury Racing Will Solve All Of Life's Problems .
Look around you, look at all the unhappy people with their tiny engines. Cadillac CT6s and Subaru BRZs with their pathetic little 2.0-liter four bangers. McLarens running around with puny 3.8 liters, an insult to the V8 configuration. No, my friend, what you need is DISPLACEMENT. Only then will you achieve TRANQUILITY and INNER PEACE. What you need is this naturally aspirated 7.0-liter, modified LS7 crate engine from Mercury Marine. And, yes, I do mean the boat engine company. What Mercury did was take an LS7 V8 crate motor from GM and give it new set of Mercury Racing designed, Edelbrock cast, aluminum DOHC four-valve cylinder heads, according to the company’s website.
