Production of the 911 Speedster

The other day, I was asked to write an article titled "At last, the new 911 Speedster is ready for mass production.When the news was announced that "the

Finally, the new 911 Speedster is ready for mass production!

My husband said, "Amazing!!!He was more excited than ever. I said, "I guess it's great news that a speedster is going into production, but is it really that great?" I asked.

GPF for cars to be launched in Europe from now on.(gasoline particulate filter)I feared that the 911 Speedster would have to be powered down or, if it was not good enough, would not be able to go into production.
In fact, theThe BMW M3 has been discontinued in Europe, and the hypercar that Mercedes-AMG had planned to produce has been delayed.Because. So, we're going to meet that standard this time.The fact that the speedster made it to production is amazing!I think Porsche did a great job. I think Porsche did a great job. However, I still have a concern that the GPF might make the sound quieter or change the sound quality.

This was the case.

GPFI've heard of it before, but if it's so important, I wanted to know about it, so I decided to do a little research.

PN regulation of EURO6

Particulate emission limits for gasoline-powered vehicles areEURO5" in 2009It began with the Then, on September 1, 2014, a regulation establishing emission limits for air pollutants from motor vehicles, theEURO6was enacted in the European Union. In this EURO6, the "EURO6" is particularly focused on theparticulate matter(micrometer (μm) sized solid or liquid particles)' and 'NOx(Nitrogen oxides))"emission limits are strictly enforced.It became.

As a result, from January 1, 2015 onward, theAll new cars sold in the EU must now meet these EURO6 limits.

In addition, starting in September 2017, the "EURO6 d-TEMPThe introduction of even stricter emission standards called "Particulate Matter(PM: Particulate Matter)The new regulation value was changed from what was the "emission mass" regulation value of theNumber of particles emitted(PN: Particulate Number)Regulation value of "0" was introducedThe reason for this is that the The reason for this is that

The regulation value for the number of emitted particles was necessary because "ultra-fine particles, which easily penetrate the human body and are feared to have an impact on human health, are not easily reflected in the value.

This is because of the fact that the number of particles That is why we regulate particles by "number of emissions".PN Regulation."was introduced. This allows automakers to reduce particulate emissions from gasoline engines byIt had to be reduced to one-tenth of what it was during the 2009 "EURO 5".

Emergence of GPF

PN(Number of particles of emitted particulate matter)Regulations are in place to regulate the PM(Particulate matter)Unlike the mass regulation ofNeed to reduce the number of fine particulate matter emissionsThere is a What it does is a filter "GPF" that has the function of collecting exhaust particulates emitted from automobile engines.(gasoline particulate filter)'.

But this GPF, according to a December 2018 automotive media article.Each piece weighs about 7 kg.Porsche has called this GPF ".One for a 4-cylinder engine."2 for 6 & 8 cylinder engines.They are equipped with a "3.

By being forced to equip the GPF, the sports car hasLighter weight technology is required than ever before, and development costs will also increase.As a result, many manufacturers have been forced to discontinue or reduce the power of their sports models.

I see, this is a big deal.

Porsche Clean Air Technology

So, I wondered how Porsche cleared up this GPF attachment problem, and I checked the Porsche Japan website.Porsche Clean AirI found an article about

It states that from September 1, 2018, Porsche will also use particulate filters on gasoline models to capture particulate matter, and six- and eight-cylinder engines will be equipped with two of them.

Porsche has been trying for about two years to incorporate particulate filters into gasoline models. In particular, theCompact engine compartment models such as the 718 and 911 cannot accommodate a large exhaust system.Therefore, they had to completely redesign the GPF.

After two years, Porsche has finallyDevelopment of a new type of GPF with low dependence on temperature and loadSuccessfully achieved in the During engine control, the filter gets hot due to maximum torque and exhaust temperature. The particulates collected by the filter are burned and regenerated over time.

The head of the development team said,It is unlikely to feel any adverse effects during normal driving.He asserts, "I'm not a fan of the new exhaust gas purification system. He says he can say this because he has thoroughly tested the new exhaust gas purification system over hundreds of thousands of kilometers of test runs.

So, back to the Speedster...this time, the new 911 Speedster is a "The 4.0L horizontally opposed 6-cylinder NA engine has a maximum output of 510hp and revs to as high as 9000 rpm.It is truly amazing that a sports car equipped with this engine has been launched and meets the standards of the EURO6 PN regulation.

Porsche has always been committed to naturally aspirated engines.tenacity"This is the result of the

NA engine to be inherited

This has led Porsche fans to say, "Until now, people have been asking if the 991.2 GT3 would be the last NA engine, but with this technology, it's not going to happen.Maybe the 992 GT3 and GT3RS will also be released in NA?There is a growing expectation that

In fact, Andreas Proininger, head of the Porsche GT division, said

The 4.0-liter horizontally opposed six-cylinder naturally aspirated engine from the new 911 Speedster will be used in future models.By sticking with naturally aspirated engines, we want to maintain naturally aspirated engines in the future.We are making a tremendous effort to develop the right engine without losing any of the emotion and performance.

He said. In fact, it has not been stated which model will use this engine, but the most likely is the next generation GT3.

Engine noise of concern

However, as my husband said, "I still have concerns that the GPF might make the sound quieter or change the sound quality." As he said, there was some information here that concerned me a little.

The only thing that stuck out was the sound. I wonder if the GPF (gasoline particulate filter) on the European version is the culprit behind the bass and the lackluster exhaust sound. We can only hope that the Japanese version has a better sound.

I see...I see. I guess I'll have to actually test drive the 992 and see it running to find out more about all this.

Both cars are scheduled to come to Ashiyu Driveway after delivery, so I will be sure to ask them to come and see them in all their glory.
