Emissions-Management

Map-controlled thermostats have an electrically controlled heating element that is integrated into the wax as an expansion material. The heating element is controlled by a map from the engine control unit and heats the expansion material, which causes the thermostat valve to open the coolant circuit.

This allows the thermostat to influence the engine temperature much more quickly in order to operate it in the optimum range in various load and operating conditions. The use of T+H HLPA high-performance heating cartridges in the map thermostats ensures that the operating temperature of the engine is constantly regulated to an optimum temperature in all the different driving situations and engine operating conditions that occur in everyday use. This has advantages in terms of fuel consumption, exhaust emissions and the service life of the combustion engine.

In conventional SCR catalytic converters, the urea solution AdBlue is injected directly into the drive train. However, since temperatures of 220 °C are required for the SCR catalytic converter to operate, conventional exhaust gas purification does not function optimally at low engine loads, during the cold start phase or in short-distance operation.

For this area, T+H offers heating solutions for passenger cars and commercial vehicles that guarantee highly efficient energy transfer to the heated medium while meeting the requirements for tightness and service life.

The current discussions about retrofitting diesel cars are in full swing. At present, the main focus is on avoiding impending driving bans in city centres. Approaches to this include retrofitting concepts for both software and hardware, such as retrofitting catalytic converters or other devices.

Effective measures on the hardware side require the use of electric heating elements. Here, T+H Automotive offers solutions that help to comply with the required emission limits.

Electrically heated catalytic converters are more relevant than ever before. The use of heated catalytic converters significantly reduces the cold start behaviour of extremely cold engine applications and allows exhaust pollutants to be eliminated much earlier.

In addition to much faster catalyst response, they enable further improved evaporation when an AdBlue urea solution is injected directly onto the hot catalytic converter.

Türk+Hillinger heating elements are used in a wide range of applications involving heated catalytic converters.
