Are the Spark Plugs’ Days Numbered?

Though little is still known about a possible RX-8 successor, the latest from Autocar includes reports of new laser ignition technology that would replace the spark plug ignition system currently used in the Wankel motor. The implication comes after a comment made by a senior engineer at Mazda that said the upcoming rotary sports car would use a “special kind of ignition system”.

The engine, internally dubbed the “16X”, would be using the laser ignition to create a more complete and controlled method of ignition for each combustion chamber allowing the rotary to run leaner and more efficiently. This would allow the new rotary to pass the upcoming European emissions regulations which the current RX8 is unable to do.

The lasers are said to measure 9mm in diameter, making them compact enough to fit in the engine and should actually require less space than a typical spark plug. The new rotary set-up will likely require a smaller hole tapped into the combustion chamber of the engine which would also lend itself well to Mazda’s aim at making a more compact and lighter weight engine. It also promises to offer more torque, in part, due to the larger 1.6 liter capacity.

There has been no word of the technology filtering down to the conventional combustion engine, but if the laser ignition concept worked well, it is conceivable that it could be applied to piston powered engines as well for improved power and could potentially enhance the combustion process. As a matter of fact, the laser ignition technology is not all that new, Ford was working on something similar in 2009.

Overall, the 16X is looking to be a promising engine and if Mazda is able to solve the issue of cost, the next rotary could be a leaner, more efficient engine with more precise timing.

A New Toy for CorkSport

As we continue to ramp up our CorkSport product line, we have been making some changes to our internal processes to increase delivery time and refine the look and design of the CorkSport brand of products. The latest investment we made is the Epilog Mini 24 Laser etching machine. Why, do you ask, would we get one of these? The laser etcher has a combination of flying-optic design and the highest quality engraving results. This provides a precise etch on a variety of materials and allows us to give you a larger selection of CorkSport logoed products with the highest quality results and precise imaging.

For example, we were originally having our MAF housings for the SRI intake machined, anodized, and then machined again for the logos. This increased the manufacturing time making it more difficult to keep it in stock and available for immediate delivery. Once we made the switch to etching our logo onto the MAF housings with the new laser etching machine, it sped up the time it took to manufacture, which meant keeping more in stock and reducing backorders and delivery times.

We also began using the machine to laser etch our logo onto the CorkSport Mud Flaps. Now, rather than applying a vinyl logo, we are able to offer the mud flaps with a durable etched logo that has a superior look that will never rub off. You can pressure wash our mud flaps without any worry of damaging the logos.

On a side note, if you want to have a custom set of logoed mud flaps made, contact Chris and he can hook you up with that.

Now that we have more flexibility with our branding process, if you have an idea of something that you would like to see branded, let us know!

Mazda and Audi – A Match Made in Heaven?

There have been rumors abound lately about a possible revival of the RX-7 and other rumors about the possible end of the rotary engine altogether, but the latest word on the street is about a possible collaboration between Mazda and Audi that just may be the savior for the rotary engine.

With the RX-8 soon to be discontinued and mixed signals from Mazda on a possible RX-9 modeled after the RX-7, the fate of the rotary engine is in the minds of many Mazda enthusiasts. The Wankel has been a signature in the Mazda lineup since 1964 when it was first showcased in the Cosmo R100 coupe.

Now there’s talk of Audi teaming up with Mazda for the next chapter of the rotary engine car by developing a rotary for the Audi A1 e-tron, Lexus’s attempt at the nearly all-electric compact with a range extender that currently uses a single-piston rotary engine to charge the batteries as the car is running.

Inside Line recently reported that sources inside Mazda say engineers are already developing new technology for the Wankel by potentially removing the conventional spark plugs and replacing them with a laser ignition. By doing this, the engine will be much more efficient and will produce less hydrocarbon emissions than the older version. The car will produce only 130g/km or carbon dioxide rather than the 299g/kg that is currently produced by the RX-8. Reports on this development are also followed by reports that a launch of the new rotary has not been green-lighted and the Mazda is seeking additional funding.

So Audi provides the influx of cash and Mazda provides the technology to put a Wankel range-extender underneath the trunk floor of the A1 e-tron. It sounds like a win-win on the surface, but talk is cheap and a Mazda-Audi partnership seems like an odd couple in the making.

More on SKYACTIV Technology with the SKYACTIV-Drive Automatic Transmission

We recently gave you the lowdown on the new SKYACTIV engine, today, let’s discuss transmissions! In a recent post on Mazda Motor Europe, Toshiyuki Kikuchi, Program Manager in the Powertrain Development Division at Mazda provided additional details about the new automatic transmission.

Mazda SkyACTIVE-Drive Transmission

The SKYACTIV-Drive combines the benefits of conventional automatics with those offered by continuously variable (CVTs) and dual clutch transmissions. The transmission has been developed with a six speed torque converter that has a full range lock-up clutch for all six gears called “full range direct drive”. The lock-up clutch ratio has been raised from 64% at the current 5-speed to 89% during vehicle operation.

This feature inhibits the loss of power often experienced during acceleration and delivers a more controlled driving feel. On the flip side, it is said to increase the noise, vibration and harshness (NVH) because there is nothing to absorb the rotational speeds of the engine transmission. Mazda has addressed this issue by adapting a new torque converter and installing a new damper to better absorb the NVH as well as a multi-disk lock-up clutch and its piston to improve clutch durability and control.

Mazda SkyACTIVE-Drive New Technologies

The new design will allow the transmission shifts quickly and smoothly, react dynamically to changes to the engine load right from low speeds, and raises the bar when it comes to fuel economy.

The new SKYACTIV-Drive automatic transmission promises to produce a green range of models within the next two years that will boast lower CO2 emissions and even lower fuel returns, without the need for alternative split/drive systems.

The 2012 Mazda 3 will feature the all-new SKYACTIV-G 2.0-liter engine and a SKYACTIV-MT six-speed manual transmission or optional SKYACTIV-Drive six-speed automatic transmission. Mazda says the new 2.0 liter, direct-injection four-cylinder is good for 155 hp and 148 lb feet of torque, which offers modest increases over the old, non-DI 2.0-liter engine.
