TOKYO – Nissan says it has reached a breakthrough in reaching a 50% thermal efficiency with its in-development e-POWER hybrid know-how, which may result in an extra discount of automotive CO2 emissions.

This new thermal efficiency degree would enhance gas consumption by 25% over the 40% thermal efficiency degree within the upcoming e-POWER engine, the company stated.

“Nissan’s latest approach to engine development has raised the bar to world-leading levels, accelerating past the current auto industry average range of 40% thermal efficiency, making it possible to even further reduce vehicle CO2 emissions,” the company stated in an announcement.

Nissan didn’t disclose when the e-POWER know-how with 50% thermal efficiency can be launched.

Toshihiro Hirai, senior vp of the powertrain and EV engineering division at Nissan, informed reporters on Friday that the carmaker is maximising the thermal efficiency of e-POWER so as to reduce CO2 emissions whereas driving.

The e-POWER, first launched in Japan in 2016, makes use of a petroleum engine to cost a battery that powers the car.

“It took 50 years to increase thermal efficiency (of conventional engines) from 30% to 40%,” Hirai stated.

“But with e-POWER, we can increase it to 50% in several years. That has been the target for the engineering community,” he stated, describing that degree because the “ultimate, challenging goal”.

To obtain this, Nissan stated it strengthened in-cylinder gasoline movement and ignition, which burns a extra diluted air-fuel combination at a excessive compression ratio.

“Without building up these fundamental technologies, we are unable to attain carbon neutrality,” stated Hirai.

The carmaker stated final month that every one of its new fashions in key markets can be electrified by the early 2030s to realize carbon neutrality by 2050.

Nissan has additionally stated it expects gross sales of multiple million electrified automobiles per year by the tip of fiscal 2023.
