Abstract
The invention discloses a gas exhaust manifold for a straight four-cylinder worm wheel supercharging engine. The gas exhaust manifold comprises a first cylinder gas channel, a second cylinder gas channel, a third cylinder gas channel, a fourth cylinder gas channel and a gas exhaust outlet, wherein a gas outlet flange is arranged on the gas exhaust outlet; the gas exhaust outlet consists of a semicircular first gas exhaust outlet and a semicircular second gas exhaust outlet; the first gas exhaust outlet serves as an outlet of the first cylinder gas channel and the fourth cylinder gas channel; and the second gas exhaust outlet serves as an outlet of the second cylinder gas channel and the third cylinder gas channel. Through adoption of the gas exhaust manifold, gas exhaust turbulent flow can be reduced, and the gas exhaust energy loss can be reduced.
Description
Technical field
The present invention relates to a kind of automobile engine exhaust system component, be specifically related to a kind of in-line four cylinder turbosupercharged engine gas exhaust manifold.
Background technique
Along with the user improves constantly the requirement of motor car engine power character, country is increasingly high to the oil consumption and the emission request of motor, and turbosupercharged engine becomes a kind of development trend.Turbosupercharging is that the waste gas inertia impulsive force that utilizes motor to discharge promotes the turbine in the turbine chamber, and turbine drives coaxial impeller, and impeller pressurized air makes supercharging air get into cylinder.The effect of enmgine exhaust is that the waste gas that motor is discharged is pooled together, and discharges through outlet pipe again.
Existing in-line four cylinder turbosupercharged engine gas exhaust manifold (referring to Fig. 3); Comprise lose heart first cylinder 10, second cylinder lose heart that the 11, the 3rd cylinder loses heart that the 12, the 4th cylinder loses heart 13, exhaust manifold 14 and the flange 9 of giving vent to anger; First, second, third, fourth cylinder is losed heart and is met at exhaust manifold 14 respectively; Be furnished with circular exhaust outlet D on the exhaust manifold 14, exhaust outlet D combines as a whole with the flange 9 of giving vent to anger.Though this gas exhaust manifold compact structure, lighter weight, each air flue is shorter; Waste gas in each air flue comes together in the exhaust manifold, discharges from an exhaust outlet D, and the exhaust flow-disturbing is bigger; The exhaust energy loss is bigger, is unfavorable for that motor makes full use of exhaust energy when low speed.
Summary of the invention
The purpose of this invention is to provide a kind of in-line four cylinder turbosupercharged engine gas exhaust manifold, this gas exhaust manifold can reduce the exhaust flow-disturbing, reduces the exhaust energy loss.
In-line four cylinder turbosupercharged engine gas exhaust manifold of the present invention; Comprise the first cylinder air flue, the second cylinder air flue, the 3rd cylinder air flue, the 4th cylinder air flue and exhaust outlet; Exhaust outlet is provided with the flange of giving vent to anger, and exhaust outlet is made up of first exhaust outlet of semicircular in shape and second exhaust outlet of semicircular in shape, wherein; First exhaust outlet is the outlet of the first cylinder air flue and the 4th cylinder air flue, and second exhaust outlet is the outlet of the second cylinder air flue and the 3rd cylinder air flue.
The present invention adopts the air flue modular design; The outlet of the first cylinder air flue and the outlet of the 4th cylinder air flue are united two into one; The outlet of the second cylinder air flue and the outlet of the 3rd cylinder air flue are united two into one; Form two independently exhaust outlets (being semicircle first exhaust outlet and semicircle second exhaust outlet), reduced the exhaust flow-disturbing between air flue; The size of semicircle first exhaust outlet and the size of semicircle second exhaust outlet have only the half the of existing exhaust outlet size respectively; Exhaust energy limited during in-line four cylinder turbosupercharged engine low speed is through less relatively exhaust outlet; Reduce the exhaust energy loss, provide more exhaust energy to drive pressurized machine, increased the wheel speed of pressurized machine; Increase the air inflow of motor, thereby increased the low speed torque of motor.
Description of drawings
