New Patent from Honda: Multi-Displacement Engines

Honda has been caught in the patent, well before the jerked it from the public eye, with a new patent on an engine with different displacement sizes on a four cylinder engine. This would allow for cylinder shut-off resulting in the potential of having an engine running in 15 different displacement configurations for maximum economy or power. Very interesting.

GM actually filed for patent on a Variable Displacement Piston Engine in 1979 by changing the displacement through a variable stroke length mechanism, but it never caught on.

Honda later cited GM’s patent when it came up with a variable stroke method of its own, but also , to my knowledge, never implemented it into a production model car: www.google.com/patents/US20090288641.

Ut oh… BOSCH is named in VW “Clean” Diesel Scandal

“Volkswagen’s fraudulent scheme was facilitated and aided and abetted by defendant Bosch, which created the software used in Volkswagen’s defeat device.”

BOSCH

The lawsuit goes on to say that Bosch is liable for triple damages for the fraud caused to U.S. consumers under anti-racketeering laws.

The latest lawsuit says “as early as 2007, Bosch warned Volkswagen that using its software in vehicles that were driven on the road would constitute a criminal offence. Nevertheless, Bosch proceeded to sell or license 11 million of the component devices to Volkswagen over the next seven years.”

Affected vehicles include the 2009-2015 Volkswagen Beetle TDI, Golf TDI, Jetta TDI, and Jetta Sportwagen TDI; the 2014-2015 Volkswagen Passat TDI; and the 2009-2015 Audi A3 TDI.

Wow! VW is in deep shit over this one.

The diesel cars were programmed to sense when emissions were being tested and to turn on equipment that reduced emissions, according to United States officials. At other times, the cars had better fuel economy and performance, but produced as much as 40 times the allowed amount of nitrogen oxide, a pollutant that can contribute to respiratory problems including asthma, bronchitis and emphysema.

 

What cars are affected by this?

The cars are 2009 to 2015 TDI Volkswagen Golf, Jetta, Beetle and Audi A3s, and the 2014 to 2015 Passat. All are powered by the company’s 2.0-liter turbodiesel four-cylinder engines. There are other diesels engines in the greater VW stable, but those aren’t affected here as far as we know.
