Fully isometric layout that increases the exhaust flow rate and improves torque.
Let's check the work of the engine. The basics are the process of converting the chemical energy of gasoline into heat energy and the work of mechanically extracting that energy.Needless to say, the process in the previous stage is important in terms of power performance.And it is a series of air flows that control it.That's why fluid dynamics are needed in the design of air inlets and outlets.So, in this paper, in that sense, the exit is actually more difficult to design.The pressure and temperature are high, and of course the flow velocity is fast.Therefore, resistance is inevitable.In addition, there is also the difficulty of pulsation due to the timing of the explosion.Especially in the exhaust manifold located right after the engine, these issues are concentrated.Therefore, the effective tuning is required.
Our basic design is a 4-2-1 (8-3 for RX-1) layout aimed at increasing torque from low to medium speeds.Considering the rotation speed and overlap characteristics of each engine, the distance to the assembly part is made longer than mass production and isometric.Furthermore, the angle of the confluence is narrowed to prevent the blow-down phenomenon (exhaust backflow) that occurs at high rpm.In addition, the joint to the XNUMXst part has a radial shape to increase the exhaust flow velocity, and the output characteristics that extend the engine's characteristics have been obtained.The functional beauty of stainless steel, which makes full use of craftsmanship such as fully machined flange and back shield manufacturing method TIG welding, is also attractive.
