    Abstract: An exhaust treatment unit for a work vehicle includes a selective catalytic reduction apparatus, a connection pipe, an ejection apparatus attached to the connection pipe, a first pipe section that guides coolant to the ejection apparatus, a second pipe section that discharges coolant from the ejection apparatus, first and second retaining sections, and a coolant pump. The ejection apparatus ejects reducing agent into exhaust supplied to the selective catalytic reduction apparatus. The first and second retaining sections retain coolant and are connected to the first and second pipe sections above the ejection apparatus, respectively. The coolant pump is driven by an engine driving force and supplies the coolant to the ejection apparatus via the first pipe section. The first and second pipe sections extend upward from first and second connecting sections of the first and second pipe sections and the ejection apparatus toward the first and second retaining sections, respectively.

    Abstract: A method is provided for detecting urea deposits in an exhaust line of an automotive vehicle and includes determination if an exhaust gas's temperature is reached, if the result of determination is positive, stoppage of urea injection, and determination of the quantity of NOx in the exhaust gases on the outlet of the selective catalytic reduction system. A comparison is performed between the quantity of NOx determined on the outlet of the selective catalytic reduction system and a theoretical quantity or a measured quantity of NOx produced by the internal combustion engine. If the comparison shows that the quantities are different, it is considered that urea deposits are present in the exhaust line. A vehicle is also disclosed.

    Abstract: A four-way exhaust gas valve has a permanent inlet, a permanent outlet, a selectable inlet, a selectable outlet and a pivotable valve flap. The pivotable valve flap is arranged for switching between a first mode of operation, in which exhaust gas entering through the permanent inlet is guided directly to the permanent outlet, and a second mode of operation, in which exhaust gas entering through the permanent inlet is discharged through the selectable outlet and exhaust gas re-entering through the selectable inlet is discharged through the permanent outlet.

    Abstract: The invention provides systems and methods for electric power production and integrated combustion and emissions control. The invention may include an engine capable of receiving air and fuel, and producing power and an engine exhaust gas. The invention may also include a first reaction zone receiving the engine exhaust gas from the engine configured to combust fuel and air having an equivalence ratio of more than one, thereby generating a first product. The combustion may reduce nitrogen containing species. The invention may also include a second reaction zone receiving the engine exhaust gas from the engine configured to combust fuel and air having an equivalence ratio of less than one, thereby generating a second product. The combustion may reduce or minimize NOx. The invention may also include a mixing zone configured to receive the first product and second product, and mix and react the first and second products, thereby generating an exhaust with reduced NOx levels. This may occur with sufficient residence time and temperature to complete combustion and promote nitrogenous species reduction reactions. For inventions with multiple zones, fuel or air or exhaust gas may be adjusted, diverted or turned off as load is reduced to maintain flame stability for all zones that remaining operational. For inventions with engine exhaust that provides less oxidant than the burner requires, an air eductor means may be arranged between the engine and the burner that entrains needed additional oxidant and simultaneously recovers the flow energy in the turbine exhaust.

    Abstract: An exhaust system for a motorcycle having a catalyzer casing that is accommodated in an exhaust muffler. The exhaust muffler is provided at opposite sides thereof in the vehicle width direction with lateral walls that are inclined so as to come closer to each other as they extend downward. A bent section is formed in an intermediate portion, within the exhaust muffler, of an exhaust gas conduit passing through a front end wall of the exhaust muffler and changes the flow direction of exhaust gas from the forward and rearward direction of the vehicle to the vehicle width direction. The catalyzer casing has one end connected to a downstream end portion of the exhaust gas conduit and is arranged in an inclined condition to be lowered as it approaches one side of the muffler in the vehicle width direction.
