Nissan's engines are more thermally efficient

Nissan has announced the development of the e-POWER hybrid technology that will deliver a 50% milestone in thermal efficiency. This technology can reduce carbon dioxide emissions from cars.

The company said: The new thermal efficiency class reduces fuel consumption by 25% compared to the thermal efficiency class of 40% for a future e-POWER engine.

The thermal efficiency of most modern gasoline engines is around 40%. In other words, when the burning fuel is converted into motion, the energy produced by the engine is only 40%.

The rest is converted to waste like heat and emissions, which means Nissan technology can reduce emissions.

The automaker was able to achieve higher thermal efficiency because its electronic power system does not operate like a conventional fuel engine, because the system does not supply the car with electricity itself, but rather works as a propulsion technology.

This means that since Nissan has increased the fuel flow to the cylinder and improved the ignition function so that the lean-air mixture burns at a high pressure ratio, the engine can still run at the highest efficiency. University student.

Toshihiro Hirai, senior vice president of Nissan Engine and Electric Vehicle Engineering, said it took 50 years to increase the thermal efficiency of conventional engines by 30% to 40%.

He added: With the help of e-Power, we can increase the thermal efficiency of conventional motors to 50% in just a few years. This is the goal of engineers who call this level a challenging final goal.

Nissan previously stated that its goal is to launch electric versions of all its new models in major markets by early 2030 and hopes to have them carbon free by 2050.

"Nissan's energy strategy has encouraged the development of high-performance electric motors and batteries, for which electronic energy is another key strategic pillar," Hirai said.

The e-POWER was first introduced in Japan in 2016. It uses a petrol engine to charge the battery that powers the car.

The company hasn't announced a launch date for its 50% efficient e-POWER system, but it did launch a new Nissan Note with the latest e-Power version in Japan in December.
