Nissan says it has boosted engine thermal efficiency to 50%

TOKYO — Nissan Motor Co said on Friday it has reached a breakthrough in achieving a 50% thermal efficiency with its in-development e-POWER hybrid technology, which could lead to a further reduction of car CO2 emissions.

This new thermal efficiency level would improve fuel consumption by 25% over the 40% thermal efficiency level in the upcoming e-POWER engine, the company said.

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 said in a statement.

Nissan did not disclose when the e-POWER technology with 50% thermal efficiency would be launched.

Toshihiro Hirai, senior vice president of the powertrain and EV engineering division at Nissan, told reporters on Friday that the automaker is maximizing the thermal efficiency of e-POWER in order to reduce CO2 emissions while driving.

The e-POWER, first introduced in Japan in 2016, uses a gasoline engine to charge a battery that powers the vehicle.

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

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

To achieve this, Nissan said it strengthened in-cylinder gas flow and ignition, which burns a more diluted air-fuel mixture at a high compression ratio.

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

The automaker said last month that all of its new models in key markets would be electrified by the early 2030s to achieve carbon neutrality by 2050.

Nissan has also said it expects sales of more than one million electrified vehicles per year by the end of fiscal 2023.

Toyota develops packaged fuel cell system to cut carbon footprint

https://www.autoblog.com/2021/02/26/toyota-fuel-cell-module/


TOKYO — Toyota Motor Corp said on Friday it has developed a packaged fuel cell system module, as it hopes to expand its usage and accessibility of the zero-emission technology amid the industry’s shift towards electric vehicles (EVs).

The world’s biggest automaker, which launched a revamped Mirai in December, has not been successful in winning drivers over to fuel cell vehicles (FCV).

The FCV segment remains a niche technology despite Japanese government backing, amid concerns about lack of fueling stations, resale values and the risk of hydrogen explosions.

The new fuel cell battery system, which has been offered in separate parts, will be available in a compact packaged module to be used as a stationary power generator or in trucks, buses, trains and ships, the company said on Friday.

Toyota said it plans to sell the module to other companies in the spring of 2021 or later, but did not disclose details on price or sales target.

“Toyota has been taking various initiatives toward the creation of a hydrogen society,” the Japanese company said in a statement.

“Through these experiences, the company has learned that many companies involved in FC products in a variety of industries are looking for FC systems that can be easily adapted to their own product.”

The automaker said it plans to offer horizontally and vertically packaged models, weighing about 240kg-250kg, each with a rated output of 60kW or 80kW.

These module models can be combined to flexibly adapt to the output level and amount of installation space available.

The module, which packages individual fuel cell system-related products of the revamped Mirai car with enhanced performance, will be produced at Toyota’s Honsha plant in Aichi prefecture, a company spokesman said.
