Abstract
The utility model relates to exhaust manifold of a petrol engine with 2.4L CBR, which comprises at least one branch pipe. A branch pipe A and a branch pipe D form a branch pipe E at the back end, a branch pipe B and a branch pipe C form a branch pipe F at the back end, and a branch pipe F and a branch pipe G form a general branch pipe G at the back end. Each branch pipe has equal length, and the optimal value of center distance of each two adjacent branch pipes is of 93mm. The exhaust manifold satisfies the requirement of equal length of each branch pipe during the design process. In addition, during the design process, the exhaust manifold uses a design structure of 4-2-1, and cancels an exhaust main pipe which is usually arranged between the exhaust manifold and a catalyst. The position of the catalyst is taken advanced being beneficial to exhaust.
Description
Technical field
The utility model relates to technical field of internal combustion engines, and relating to a kind of air displacement specifically is the petrolic discharge manifold of 2.4LCBR.
Background technique
The effect of the discharge manifold of motor is that air outlet flue and catalyst converter are coupled together.In order to reach emission standard, all wish the catalyst converter position in advance at present, this is highly beneficial to discharging.And in order to make each cylinder exhaust not disturb and the phenomenon of exhaust gas recirculation does not take place, and utilize exhaust inertia as much as possible, improve exhaust efficiency, wish generally in the engine design process that the long and length of each arm may be isometric.But in the real process, because outlet pipe is complex-shaped, and the demand of coupling vehicle, generally be difficult to accomplish above some requirement.
The model utility content
The utility model is at the deficiencies in the prior art, designed and developed out motor vehicle emission favourable, each cylinder exhaust is not disturbed and the phenomenon of exhaust gas recirculation is not taken place, and utilizes exhaust inertia as much as possible, improves 2.4 liters of petrolic discharge manifolds of CBR of exhaust efficiency.
The utility model is achieved through the following technical solutions:
A kind of 2.4 liters of petrolic discharge manifolds of CBR include at least one arm, and arm A and arm D be synthetic arm E in the rear end; Arm B and arm C be synthetic arm F in the rear end; Arm F and arm G be synthetic total arm G in the rear end.
A kind of 2.4 liters of petrolic discharge manifolds of CBR, described each arm is isometric.
A kind of 2.4 liters of petrolic discharge manifolds of CBR, the centre distance of described each adjacent arm is 85mm～100mm.
A kind of 2.4 liters of petrolic discharge manifolds of CBR, the centre distance optimum value of described each adjacent arm is 93mm.
2.4LCBR the demand discharge manifold of motor is isometric as much as possible.This money discharge manifold has been accomplished the isometric demand of each arm in design process.This money discharge manifold has been used the project organization of 4-2-1 in design process in addition, has cancelled discharge manifold commonly used and the exhaust manifold between the catalyst converter.Make the catalyst converter position in advance, this is highly beneficial to discharging.
