  • Naturally aspirated common rail diesel engine meeting ultra low PM emission by passive exhaust after treatment
    Patent number: 11391250
    Abstract: Systems (100, 200 and 300) and methods (400, 500 and 600) for controlling exhaust gas emissions from naturally aspirated engine are disclosed. The system (100, 200 and 300) includes an open loop exhaust gas recirculation flow to the engine. The system (100, 200 and 300) includes a diesel oxidation catalyst (102, 202 and 302) mounted on or near exhaust manifold (106, 206 and 306) of the engine. Furthermore, the system (100 and 200) includes an exhaust gas mixing conduit (114 and 214) inserted into air intake conduit (104 and 204). The system (100, 200 and 300) further includes an exhaust gas recirculation valve (110, 210 and 310) mounted on cold side or a hot side of EGR cooler. Furthermore, the system (100, 210 and 310) includes an electronic control unit to control exhaust gas recirculation valve (110, 210 and 310) along with various other engine calibration parameters.

  • NATURALLY ASPIRATED COMMON RAIL DIESEL ENGINE MEETING ULTRA LOW PM EMISSION BY PASSIVE EXHAUST AFTER TREATMENT
    Publication number: 20160169164
    Abstract: A system (100) for controlling emissions of exhaust gases in said naturally aspirated engine is disclosed. The system includes an open loop exhaust gas recirculation flow. The system (100) further includes a catalyst (102) mounted at exhaust manifold (106) of the engine. Furthermore the system (100) includes an exhaust gas mixing tube inserted into intake elbow (104) (mixing tube). The system (100) further includes an exhaust gas recirculation valve (110) mounted on cold side of EGR cooler. Furthermore, the system (100) includes an electronic control unit to control exhaust gas recirculation valve (110) along with various other engine calibration parameters.
