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.

Abstract: An operating mechanism (178) for disengaging a cruise control lever (176) operatively engaged with a hydrostatic transmission of an off-road vehicle, the cruise control lever (176) rotatably mounted over a cruise shaft bracket (188) and capable of being acted upon by biasing and counter-biasing forces along a rotational axis of the cruise control lever (176), the operating mechanism (178) comprising, a first cable (226) and a second cable (228), the first and second cables (226, 228) coupled to LH and RH brake pedals (222, 224), respectively, via their one end and extending to be operatively coupled to a brake actuation linkage assembly (230) via their opposite end, a cable holding member (232) formed to have equilateral triangular ends and coplanarly arranged between the first and second cables (226, 228).

Abstract: A lubrication system for turbocharger(s) ensures continuous lubrication of bearings and shaft of the turbocharger with lubricant retention during start and shut down of turbocharger-associated systems thereby enhancing the performance and turbocharger life. A shaft and bearings are lubricated by introducing pressurized lubricating oil through an oil inlet passage in the bearing housing and after lubricating, the lubricant returns to the engine oil sump located below the turbocharger through the oil outlet passage. A valve in the oil inlet pipe line permits lubricant flow to the bearings during engine running, and when the engine stops and oil pressure falls below the valve opening pressure, the valve shuts and traps the lubricant in oil inlet pipe that is above the valve. The oil outlet pipe retains sufficient lubricant in the bearing housing which lubricates the shaft and bearings post engine shutdown.

Abstract: The present invention relates to lubrication system for turbocharger(s) [TC] to ensure continuous lubrication of bearings and shaft of the turbocharger with lubricant retention during start and shut down of turbocharger-associated systems thereby enhancing the performance and turbocharger life. The shaft (6) and bearings, are lubricated by introducing pressurized lubricating oil through an oil inlet passage (12) in the bearing housing (4) and after lubricating, the lubricant returns to the engine oil sump located below the turbocharger through the oil outlet passage (13). A non return valve (15) or one way valve in the oil inlet pipe (16) line permits lubricant flow to the bearings during engine running, and when the engine stops and oil pressure falls below the NRV (15) opening pressure, the NRV (15) shuts and traps the lubricant in oil inlet pipe that is above the NRV (15).

Abstract: A conventional aluminum killed alloy steel for case hardening of gear(s) and/or shaft components consisting of 0.10 to 0.30 weight % Carbon, 0.15 to 0.35 weight % Silicon, 0.8 to 1.5 weight % Chromium, 0.6 to 1.5 weight % Manganese, 0.017 to 0.040 weight % Aluminum, and balance iron including impurities, produced by vacuum degassing and alike routes. Gear(s) and/or shaft components made by the above steel when treated by modified carbonitriding followed by hard shot peening process provide both superior bending fatigue strength and pitting fatigue life, capable of withstanding higher torque levels and speeds.
