Diesel engines of the “new generation” with direct fuel injection are known for their high mechanical efficiency. However, this growth in efficiency does coincide in a decrease of the available amount of heat in the coolant. At low ambient temperatures the heat dissipated by the engine is no longer sufficient to ensure a quick defrosting of the windshield and a comfortable temperature level inside the passenger compartment. Besides the familiar auxiliary heating systems such as aux. fuel heaters or the PTC heaters this problem can be solved by the use of a Visco® heater. This following article will describe the function of the Visco® heater, its integration into the vehicle as well as its effects on vehicle heat up and fuel consumption.
