In a bid to cut costs and meet stricter environmental standards, Nissan Diesel Motor Co. announced Monday it will buy diesel engines for midsize trucks from Hino Motors Ltd. starting in 2004.

Nissan Diesel said it will purchase 13,500 diesel engines for some 10 billion yen annually from Hino, the biggest heavy truck maker affiliated with Toyota Motor Corp.

Hino's new engines, featuring low particulate matter and nitrogen dioxide emissions, will be installed in Nissan Diesel trucks with a loading capacity of 4 tons. The trucks will be marketed in Japan and overseas, Nissan Diesel officials said.
