1. A diesel exhaust gas collection and treatment system (100) for collecting exhaust gas from a diesel engine powered vehicle, treating the exhaust gas with injected ambient air, then releasing the air and exhaust gas mixture to the atmosphere, wherein the system (100) comprises:
(a) a vehicle (110) powered by a diesel engine (111), wherein the diesel engine (111) comprises an exhaust manifold (112) disposed thereon, wherein a stream of exhaust gas from operation of the diesel engine (111) flows from the diesel engine (111) through the exhaust manifold (112); and (b) a generally tubular exhaust collector (120) having an anterior collector end (121), a posterior collector end (122), and a collector side wall (123), wherein an anterior chamber (125) is disposed therein adjacent to the anterior collector end (121) and a posterior chamber (126) is disposed therein adjacent to the posterior collector end (122), wherein the anterior chamber (125) is separated from the posterior chamber (126) via a non-solid planar divider (127), wherein the exhaust collector (120) comprises
(i) an exhaust inlet port (130) centrally disposed on the anterior collector end (121), wherein the exhaust inlet port (130) is fluidly connected to the anterior chamber (125), wherein the exhaust inlet port (130) is fluidly connected to the exhaust manifold (112) via exhaust piping (113),(ii) a plurality of ambient air injection ports (140) disposed on the posterior collector end (122), wherein each air injection port (140) is fluidly connected to the posterior chamber (126),(iii) a plurality of ambient air injection tubes (150), wherein each air injection tube (150) is fluidly disposed on and connected to a corresponding air injection port (140), wherein each air injection tube (150) comprises an injection tube inlet (151) and an injection tube outlet (152), wherein the air injection tube inlet (151) and the air injection tube outlet (152) face a same direction, wherein the injection tube comprises a tube inlet diameter (153) at least two times larger than a tube outlet diameter (154) for acceleration of the ambient air passing through the air injection tube (150),(iv) a plurality of collector outlet ports (160) disposed on the exhaust collector side wall (123), wherein each collector outlet port (160) is fluidly connected to the anterior chamber (125), and(v) a plurality of collector outlet pipes (170), wherein each collector outlet pipe (170) is disposed on and fluidly connected to a corresponding collector outlet port (160), wherein each collector outlet pipe (170) comprises an open outlet pipe terminating end (171) facing a direction opposed the injection tube inlet (151),wherein the exhaust collector (120) is flexibly suspended underneath the vehicle (110), wherein the exhaust collector (120) is disposed adjacent to a first vehicle side (115) or a second vehicle side (116),wherein the exhaust collector (120) comprises flexible connections disposed thereon between the air injection ports (140) and the air injection tubes (150),wherein a combined collector outlet port cross-sectional area (161) is at least two times greater than an exhaust inlet port cross-sectional area (131),wherein the exhaust inlet port (130) is disposed opposite the air injection ports (140) to optimize mixing of the stream of exhaust gas and the accelerated stream of ambient air from the ambient air injection ports (140), wherein the collector outlet ports (160) are disposed at a right angle to the exhaust inlet port (130) and the air injection ports (140). |
