    Abstract: A speed-determining system in an internal combustion engine is disclosed. The internal combustion engine includes a crankshaft, a camshaft, and an engine control module (ECM). The system includes a first gear that rotates with the crankshaft and a second gear attached to the camshaft. At least one idler gear is operatively meshed with the first gear and the second gear. A fuel pump gear, meshed with the idler gear, is driven proportionally to the first gear and the second gear. The fuel pump gear includes a transversal face, a circumferential lip portion, and a number of notches along the circumferential lip portion. A proximity sensor, in communication with the ECM, is spaced from the second gear. A rotation of the fuel pump gear moves the notches relative to the proximity sensor, triggering the proximity sensor to register movement of the fuel pump gear and calculate at least a camshaft speed.

    Abstract: An emissions cleaning module includes a first and second conduit. The first conduit contains a diesel oxidation catalyst (DOC) module and a diesel particulate filter (DPF) module; the second conduit contains a selective catalytic reduction (SCR) module. The emissions cleaning module is mounted to an external support by means of a mounting mechanism including at least one adjustable strap which is clamped around a conduit; and at least one saddle which is mounted to the conduit by the at least one adjustable strap. The saddle includes a curved upper surface configured to conform substantially to a portion of the conduit.

    Abstract: It may be necessary to eliminate soot from combustion engine emissions in order to comply with regulatory requirements. It may be desirable to avoid the need for a separate aftertreatment apparatus in order to eliminate soot from combustion engine emissions.A compression ignition engine may be configured to result in combustion having a peak value of equivalence ratio of less than 4.0 at the lift off length of the flame. This may result in particulate emissions of fewer than 1012 particles per kWh.
