Tokyo fudge
Mitsui & Co, Japan has admitted that it obtained an approval to sell its Diesel Particulate Filter ( dpf ) by using falsified tests results. dpf are after-treatment exhaust devices, that provide more than 90 per cent control of diesel particulate matter (pm). False data was included in the certification application for Mitsui's dpf, submitted on February 2002. Based on this certificate, the company was able to sell substandard dpfs in Tokyo: around 21,500. The Tokyo Metropolitan Government (tmg) is now planning to file a criminal compliant against Mitsui.

This operation cost it billions of yen. But 10 months before these regulations were enacted
