The name probably heard a lot of people, but if you talk about BMW's twin-scroll single turbo is not very familiar, in fact, different names but the same principle. exhaust manifold manufacturer By design, the dual channel turbocharger designs have two exhaust ports, a 4-cylinder engine, for example, a cylinder and 4-cylinder exhaust vent through a vortex tube, 2-cylinder and 3-cylinder through another vortex tube exhaust, exhaust unrelated groups. The reason for this is because in a single working cylinder, a resonance pulse of gas, the influence of the exhaust efficiency of the other cylinder, the cylinder will be working at a back pressure increases. When the working cylinders, the cylinders have an overlap time period of the intake valve and exhaust valve are in the open state, the next time the ignition cylinder has an exhaust, this very short period of time, if the cylinder 1 cylinder and the exhaust pipe 3 connected this will result in a block before the intake air is reduced, resulting in the total power of the next cycle is reduced.BMW N55 3.0T engine is also used in dual channel technology, in-line 6-cylinder firing order is 1-5-3-6-2-4, which is a group of 123 cylinders, 456 cylinders a group. So that each cylinder will not be acting under the influence after a cylinder acting. The N55 engine maximum output of 306 horsepower, torque output is amazing you can actually turn between 1200-5000 reached a peak of 400 Nm, which makes a huge body 535i GT can do 6.3 seconds to accelerate the achievement of one hundred kilometers, Shuangliu Road technological inventions to improve the conditions for a good turbo intervention is turbocharged models can start working at low speed situations.
