diesel particulate filters (DPFs) for the three others starting in April to save investment and
Isuzu and the three other truck makers -- Hino Motors Ltd., Mitsubishi Motors Ltd. and Nissan
Diesel Motor Co. -- face impending emissions regulations in Japan.
The Tokyo metropolitan government plans to require vehicles with diesel engines to have the filters on an experimental basis from fiscal 2001 as a step to cut air pollution.
Isuzu is said to be the only Japanese truck manufacturer capable of mass-producing DPFs. If other local governments take similar action and Isuzu cannot produce enough DPFs, the three others will also start making the filters with technical help from Isuzu.
