Mazda launching DPF-equipped light Bongo truck
9 December 2003
Mazda Motor Corporation has introduced a new diesel engine and a diesel particulate filter (DPF) system to its Mazda Bongo van and truck range. The upgraded vehicle, first announced in May, goes on sale today in Japan. It is the first light commercial vehicle to employ a DPF system.
The new Mazda Bongo vans are the first light commercial vehicles to comply with Japan’s New Short-term Diesel Emissions Regulations (2003/2004) and the Automobile NOx/PM Control Law, making them eligible for sale and registration in Japan’s major metropolitan areas.
The new 2.0-liter inline four cylinder, common-rail direct injection turbo diesel engine (RF-CDT type, based on the MZR-CD engine from the EU specification Mazda6) delivers improved performance compared to the previous 2.2-liter diesel engine. Maximum output has been increased from 58 kW @4,250 rpm to 63 kW @3,500 rpm. Maximum torque has been enhanced by around 30% from 138 Nm @2,000 rpm to 178 Nm @2,000 rpm. Comparing the fuel efficiency (10.15 mode) of a manual front-wheel drive, wide-low long body truck, the new 2.0-liter diesel engine achieves a 6.49 l/100km compared to the previous 2.2-liter diesel engine’s 7.35 l/100km.
PM emissions have been reduced by 75%, while NOx emissions have been cut by 25% compared to the 2.2-liter diesel engine (R2 type) previously used in the Bongo series.
