Announced a company Nissan has achieved a breakthrough in achieving 50 percent thermal efficiency with its e-POWER hybrid technology under development, which could further reduce carbon dioxide emissions in cars.
The company said: This new thermal efficiency level improves fuel consumption by 25 percent over the 40 percent level of thermal efficiency in the upcoming e-POWER engine.
Most modern gasoline engines have a thermal efficiency of about 40 percent, in other words, only 40 percent of the energy generated by the engines when burning fuel is converted into motion.
The rest is converted into waste such as heat and emissions, which means that Nissan technology can lead to lower emissions.
The automaker was able to achieve the higher thermal efficiency because its e-Power system does not operate like conventional fuel engines, as the system does not power the car itself, but rather acts as a generator dedicated to electronic powertrain technology.
This means that the engine can run at its maximum efficiency all the time, as Nissan has enhanced fuel flow within the cylinder and ignition, burning the dilute air-fuel mixture at a high pressure ratio.
And theHe said (Toshihiro Hirai) Toshihiro Hirai, Senior Vice President of Engine and Electric Vehicle Engineering at Nissan: It took 50 years to increase the thermal efficiency of conventional motors from 30 to 40 percent.
“We can increase the thermal efficiency of conventional motors to 50 percent in several years with e-Power,” he addedThis was a goal for the engineering community, describing this level as the tough ultimate goal.
Nissan previously stated that it aims to have an electric version of all its new models in key markets by early 2030 and that it hopes to achieve carbon neutrality by 2050.
And he said Hirai: Nissan’s electricity strategy promotes the development of electronic motors and high-performance batteries for electric vehicles, with electronic energy being another important strategic pillar..
The e-POWER was first introduced in Japan in 2016, and it uses a petrol engine to charge a battery that powers the car.
The company has yet to announce when the e-POWER system will be launched with an efficiency of 50 percent, but it did launch an all-new Nissan Note powered by the current version of e-Power in Japan in December.
