Mazda to mention power, direct injection and turbocharger technology

Mazda hopes that the new 2.3-liter direct-injection turbo engine to promote its latest six-speed transmission is eligible for Chinese car sales. This is the first time the two powertrain joint industrial technology in the United States. Renault 1.5 turbocharger Since the 274-horsepower (204 kW) of power output and 380Nm of torque, six-speed manual transmission will be the biggest selling point of Mazda cars in the United States.

     Mazda North American automotive business Weierdengmeng race car production supervisor, said: "Due to a large number of side shoots enough torque performance and low number of revolutions, the six-speed transmission car combines all the advantages of a turbocharger, including the surprising fuel economy and emission standards in favor of eco-environment. "

     Tut by introducing direct injection system in turbocharger applications, Mazda has broken through the barriers turbocharged usually low torque. Cars exercise also helps the engine to meet stringent pollution regulations.

     By directly injecting fuel into a combustion chamber, clio 1.5 dci turbocharger and to promote its evaporation under more than the air intake control condition, the load efficiency of the fuel mixture is improved, but in the conventional air intake system 3000 rev / min, the percentage increase in torque ten.

     Atomized fuel directly injected into the cylinder resulting in refined fuel mixture around the spark plug molding, it is possible to prevent the ignition of the engine damage can not occur. The mixture allows the ignition timing a certain delay, instead of a risk of not firing, which helps to maintain the exhaust gas temperature. Direct injection may also be generated in the internal cooling effect within the combustion chamber, allowing the presence of 9.5: 1 compression ratio higher.

     From the engine turbocharger turbine uniaxial. Uniaxial turbine from the accelerator operating speed of about 2500 r / min starts transmitting a great propulsive force. Mazda Motor Corporation believes that a simple single-axis turbine lightweight construction improves reliability.
