Mazda Motor Corporation has urbanized a greatly better spotless diesel engine so as to rapidly output and environmental presentation similar to a gasoline engine. It determination be increasingly proof to similar to approximately the world, start in Europe in 2009.
The newly urbanized MZR-CD 2.2 spotless diesel engine has a displacement ten proportion better supposed Mazdas present MZR-CD 2.0-liter diesel, and achieves top collection of students torque of 400 Newton meters. Improved petroleum injectors and a inferior compression ratio contribute to its improved petroleum efficiency. Additionally, the heavy diesel particulate filter (DPF) skin a Mazda-developed world-first catalyst start device so as to enhances the removal of particulate substance (soot) as of the exhaust gases. The new catalytic combustion action procedure enables the DPF to be on fire off particulate substance about 60 proportion earlier supposed present systems. Due to petroleum technological advancement, the MZR-CD 2.2 is spotless sufficient to qualify for the Euro 5 emissions standards. (This is feature on a Mazda in-house assessment.)
Furthermore, the adding of a dual equilibrium ray and a additional rigid engine chunk has resulted in a important decrease in engine vibration, and theater attain very quiet operation.
Main skin of the new MZR-CD 2.2 spotless diesel engine:
2.2-liter DOHC ordinary rail turbo diesel engine
Top collection of students far above the ground presentation spotless diesel engine:
136 kW/185PS maximum authority output
400 Nm maximum torque
Excellent petroleum monetary system of 5.6 L/100 km
Greatly better quietnes
Newly urbanized diesel particulate filter (DPF)
Mazdas new spotless diesel engine has a far above the ground thermal confrontation diesel particulate filter (DPF) by means of a catalyst so as to optimizes the combustion of soot in the exhaust. The catalyst skin a inappropriately world-first start mechanism. Combined by means of additional exact engine control, petroleum device doubles the gap recognized by DPF regeneration cycles, and reduces the occasion to total the regeneration procedure to a come into view of the occasion ,essential for conservative systems.
Catalysts use the oxygen contained in exhaust gases to be on fire off particulate matter. In arrange to initiate combustion, the hotness of the exhaust gas have to be increased. This characteristic extra fuel, construct adversely put at risk overall petroleum economy.
The ceramic bottom fabric in Mazdas sole catalyst has a molecular arrangement so as to enables the simple movement of oxygen file inside it. This additional oxygen can be supplied as necessary to considerably add to the speed of particulate substance combustion, efficiently the DPF regeneration speed.
As a result, the new catalyst device reduces the quantity of petroleum necessary to be on fire off the particulates (soot). This improves the overall petroleum economy, and consequences in inferior CO2 emissions and cleaner exhaust gases.
