Hazard

In the catalytic muffler of compressed natural gas (CNG) vehicles, the catalyst fixing method is inadequate, causing the catalyst fastening to loosen under operating conditions. Continued use in this state may cause the catalyst to interfere with the muffler interior wall, generating abnormal noise. In the worst case, catalyst breakage may allow exhaust emissions to exceed CNG vehicle emission technical guidelines.

圧縮天然ガス(CNG)車の触媒付消音器において、触媒の固定方法が不適切なため、使用状態により触媒の固定が弛むものがある。そのため、そのままの状態で使用を続けると、触媒が消音器内壁と干渉して異音が発生し、最悪の場合、触媒が破損して、排出ガスがCNG車の排出ガス技術指針値を超えるおそれがある。

Remedy

Inspect the catalytic muffler on all vehicles. If a subject catalytic muffler is installed, replace the entire catalytic muffler assembly with a corrected part.
