Peugeot latest engine turbo technology uses a measure

With the pressure required to reduce emissions grew, more and more manufacturers currently started producing small engines. Add a turbocharger is a reasonable means to ensure that the performance does not decrease, but such systems are becoming increasingly complex.

     To reduce the engine displacement, KP35 turbocharger it must reduce the basis of the engine's maximum speed or reduce acceleration at low speeds. Engineers use turbo to enhance the driving cycle performance of any need for pressurized parts.

     In order to solve the problem of the low speed, the most common method is to use a turbo with a lower inertia of the relief valve, since the pressure relief valve can be closed to prevent the occurrence of the engine speed is too high and sometimes broken. Can take a long time to get those big momentum to increase the volume of high-performance turbo engine.

     PSA Peugeot Citroen Group rates closer to introduce the new engine, the engine uses, types of parallel continuous bipolar turbo systems. That there are two small turbo operating together at high speed, 452204-5005S Turbocharger but only one turbo transmission torque at lower engine speed. Other bipolar turbo has been put into the system, but these systems are bipolar turbo sequential operation, only in a certain time.

     The engine is a displacement of 2.2 liters DW12B, four-cylinder diesel engine can produce 125 kilowatts of power. Lione Passeron PSA mid-range powertrain manager, said the main goal is to offer the project to invent a small engine to replace the medium in the engine PSA product range.

     "When increasing the specific output of the engine, will reduce the torque and power performance at low engine speeds." Passeron said, "We aim to achieve the 2002 BMW single turbo pressure of 3.0 liters diesel engine has the same power performance."

     "Mono-turbocharger family used for the entire range of the engine. To maintain a low-speed torque, which must be split into two turbochargers first one turbine for low speed, but is always running. The second turbine operation when the speed reaches 2,750 revolutions per minute. "

     The system has a high and rare 2.8 bar boost pressure. The main difference between this system and the BMW system is that the former is used to turn the speed range of 1,300 to 5,000 per minute, which has 3 bar boost pressure, but the application was late. >Click here to visit
