Abstract
The invention discloses an advanced exhaust recovery system of available energy of diesel waste gas, consisting of a plurality of exhaust pipe units and expansion joints. Each exhaust pipe unit comprises a pipe body (1) and an exhaust branch (3). The pipe diameter of the exhaust branch (3) is tapered. One end of the exhaust branch intersects with the pipe body (1) at a right angle and the other end of the exhaust branch is connected with the vent of an air cylinder. After a plurality of exhaust pipe units are connected, the pipe body (1) of the connected exhaust pipe units constitutes an exhaust collector. One end of the exhaust collector is sealed up and the other end of the exhaust collector is connected with a turbine inlet. The advanced exhaust recovery system has rational structure and simple structure. As the exhaust pipes are connected in series and the vent of each air cylinder is connected with the exhaust pipe unit, exhaust pulse energy can be effectively used. A pulse system can respond quickly, so the diesel has good acceleration performance. When the diesel runs at low speed, as the energy damper loss of waste gas is relatively less, pulse energy can be better used and the diesel ahs better low-speed torque performance.
Description
Technical field
The invention belongs to the diesel exhaust technical field, what relate generally to is a kind of advanced recovery and exhaustion system for reusable diesel exhaust gas.
Background technique
Known high-speed diesel engine vent systems has level pressure turbo charge system and impulse pressure charging system.The characteristics of level pressure turbo charge system are that the gaseous-pressure before the turbine keeps certain basically.Each cylinder exhaust of diesel engine is all received on the exhaust manifold, and the volume of exhaust manifold is enough big, could play steady pressure, and turbine is single suction port.Its advantage is that efficient is higher, and air outlet duct system is simple in structure, and the exhaust manifold sectional area is big, the low shortcoming of pulse energy utilization ratio but exist; The characteristics of pulse turbocharging system are to do the exhaust branch pipe of each cylinder of diesel engine shortly and thin, normally two cylinders or three cylinders connect into an outlet pipe, each root outlet pipe all is connected with a suction port of turbine, and the volume of whole exhaust piping is less.Its advantage is an exhaust pulses energy utilization ratio height, and shortcoming is that the pressure surge in exhaust pipe structure complexity, the outlet pipe is big.
Summary of the invention
Purpose of the present invention promptly produces thus, proposes a kind of advanced recovery and exhaustion system for reusable diesel exhaust gas.It is can utilization ratio low to have solved in the level pressure turbo charge system pulse, big, the exhaust pipe structure complicated problems of pressure surge in the impulse pressure charging system.
For achieving the above object, the technological scheme that the present invention takes is: it is made of a plurality of outlet pipes unit and expansion joint, and each outlet pipe unit includes body and exhaust branch pipe, the caliber convergent of exhaust branch pipe, one end and body are angle and intersect, and the other end is connected with cylinder exhaust port; Its body portion of serial connection back, a plurality of outlet pipes unit has just been formed exhaust manifold, the end sealing of this exhaust manifold, and the other end connects turbine inlet.
The present invention is reasonable in design, and is simple in structure.Because it is the series type exhaust pipe structure, and connects an outlet pipe unit in the exhaust ports of each cylinder.Effectively utilized the waste gas pulse energy, the response of pulse system is very fast, makes diesel engine have acceleration performance preferably; When the diesel engine low cruise, because the restriction loss of exhaust energy is less relatively, can utilize pulse energy preferably, make diesel engine have low-speed torque characteristic preferably; This venting gas appliance is simple in structure in addition, and the component kind is few, uses a large amount of same parts, effectively reduces cost.System compares with the pulse super high pressure-charging, and the quantity of part has reduced 25% in each unary tie point and the venting gas appliance, and the kind of part has reduced 50% in the device.The combination of this venting gas appliance and other system of diesel engine makes diesel engine have advantages such as row's temperature is low, fuel consumption rate is low, makes this serial diesel engine have good competitive advantage.

Embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiments of the invention:
As shown in Figure 1: it is made of present embodiment a plurality of outlet pipes unit and expansion joint, and each cylinder connects an outlet pipe unit in its outlet port.Each outlet pipe unit includes body 1 and exhaust branch pipe 3 (as shown in Figure 2), and body 1 is a cylindrical shape, and its two ends are provided with the flange connector 2 that connects expansion joint 5 usefulness; Exhaust branch pipe 3 directly is connected with corresponding cylinder exhaust port by flange 7.The caliber convergent of exhaust branch pipe, seemingly one is contraction-like nozzle, and an end and body 1 are angle and intersect, and the other end is connected with cylinder exhaust port; Exhaust manifold has just been formed by expansion joint 5 its body portion of serial connection back in the outlet pipe unit of each adjacent cylinder, and an end of this exhaust manifold is sealed by end cap, and the other end is that the exhaust manifold outlet is connected with turbine inlet.
The working principle of present embodiment is after the inblock cylinder valve is opened, waste gas promptly flows into exhaust branch pipe, because the structural feature of exhaust branch pipe is accelerated waste gas therein, makes the air-flow that flows into exhaust manifold have higher kinetic energy, but its pressure obviously descends, and has reduced the pressure surge among the house steward.The speed of exhaust branch pipe jet expansion can pass to the gas that has certain speed in the house steward, flows to turbine inlet more together.Because the volume of exhaust branch pipe is very little, so nozzle is to having played the power buffer action between exhaust manifold and the exhaust branch pipe, make the pulsating pressure at cylinder exhaust initial stage can directly not pass to exhaust manifold on the one hand, suppressed exhaust pressure wave disturbs other cylinders by exhaust manifold scavenging effectively, on the other hand, the inflation and the period of exhaust in exhaust branch pipe space are shortened, pressure in the exhaust branch pipe can be caught up with the variation of inner pressure of air cylinder rapidly, reduce the restriction loss of air-flow at the exhaust valve place, because exhaust branch pipe is installed in the cylinder exhaust port place, so eliminated the pressure wave reflection problem that runs into when the multiple pulse supercharging.
