A vehicle engine exhaust gas treatment system () for use on a tractor comprising storage means () for storing urea, injector means () for injecting urea into a catalytic converter () located in an exhaust () of an engine (), an air duct () via which air is drawn into the engine, and cooling means for cooling the urea on its passage from the storage means to the injector means, the cooling means comprising a heat exchanger which includes an inner pipe () through which the urea flows on its way to the injector means, the inner pipe extending within the air duct () to cool the urea.

Vehicle exhaust treatment systems

A weighing sensor including a base () fixed to a housing, a load sensor () connected to the base in a displaceable manner via two arms (), a lever system () having at least one lever and transmitting the load acting on the load sensor to a transducer (), and a built-in calibration weight () which may be lowered onto a support region () for checking and/or calibrating the sensitivity of the weighing sensor. The support region is guided in a parallel manner by two additional arms () and is connected to a lever () of the lever system () via a coupling element (). Relatively large loads on the weighing sensor may be simulated with relatively small calibration weights, without the need for complicated lifting devices. The two additional arms () are connected on the one hand to the support region () and on the other hand to the load sensor () and are located on the side of the load sensor () opposite from the lever system ().
