An electric device has a driveshaft with at least one stator cylinder positioned between opposing, curvilinear shaped cams mounted on the driveshaft, where the center axis of the stator cylinder is parallel with but spaced apart from the driveshaft axis. A magnet assembly is disposed in each end of the stator cylinder, with one magnet assembly engaging one cam and the other magnet assembly engaging the other cam. Each magnet assembly includes a cam follower that can move along a curvilinear shaped cam. A magnet slide arm attached to the cam reciprocates magnets carried on the magnet slide arm through electromagnetic windings disposed around the stator cylinder. An electrical input delivered to the windings can reciprocate the arm, driving the cams to rotate the driveshaft. Alternatively, rotation of the driveshaft can be used to reciprocate the arm to induce electric current in the windings.

In a tractor, a radiator is arranged on one front-rear side relative to an engine. A cooling fan is provided between the radiator and an engine. A fan drive belt is wound around a fan support shaft and around an output shaft of the engine extending below the fan support shaft. A compressor is located above the output shaft and is supported to the engine at a position offset to one lateral side of the engine relative to the fan support shaft. A compressor drive belt is wound around the output shaft and a compressor drive shaft. The compressor drive belt is located on a side where the compressor is located relative to the fan support shaft, when viewed in a front-rear direction.

The present disclosure describes methods for evaluating ammonia storage capacity of a close-coupled SCR unit while remaining compliant with prescribed emissions limits, methods of controlling an emission aftertreatment system including multiple SCR units and emission management systems for a vehicle including an internal combustion engine and an emission aftertreatment system that includes two or more SCR units.

The present invention discloses a system for providing mobile power, in which the required equipment for the power supply system at fracturing fields as well as connection cables and connection hoses are integrated properly, assigned onto three transport vehicles for movement and effectively connected. Intake components and a turbine generation system are combined on a first transport vehicle and installed together, then transported to customer sites directly, thus saving the installation time at the user sites. The two different designs on the locations of an exhaust stack and an exhaust silencer not only meet the requirements of road transportation, but also meet the requirements of exhaust gas emission during operations.
