It is understood that MANN+HUMMEL is establishing and expanding its testing capabilities to meet the increasing demand of automotive manufacturers for improving the signal quality of air flow meters. With the increasingly stringent requirements of exhaust emission standards and fuel economy indicators, the accuracy of signals has become increasingly important. Especially in diesel engines, the air flow meter is the main source of information for the electronic control unit, and the electronic control unit regulates the exhaust gas recirculation and the fuel injection rate, so the combustion quality of the fuel mixture directly depends on the quality of the air flow meter signal.
Precise signal
MANN+HUMMEL has designed, built and commissioned a benchmark test rig in Ludwigsburg, Germany. The development engineer measures the signal accuracy of the prototype part and determines the factors that affect the signal of the air flow meter. In this way, a master transfer function (MTF) can be generated to convert the actual air flow signal to the voltage or frequency of the engine control unit. The control unit processes the information and ensures that the fuel injected by the injector can be completely burned.
In addition, MANN+HUMMEL has established production process measurement test rigs in factories in China, Mexico and Spain. In China, MANN+HUMMEL's professional testing team focuses on testing the first integrated air flow meter (MAF) air purifier manufactured by MANN+HUMMEL in China to ensure that the product has an accurate air flow meter signal before it is delivered to customers. . Due to the customer's design trend requirements, MANN+HUMMEL has now launched more and more integrated air flow meter air purifier projects. With this test stand, MANN+HUMMEL has further improved its development capabilities in China and provided them with value-added services while adhering to customers' design concepts. As an international automotive industry development partner and original equipment supplier, MANN+HUMMEL will also implement the detection of air flow meters in commercial vehicles.
2K Water Deflector Injection Mould
The water deflector is between the windshield and the wipers,used to house the wipers, sprinklers and rainwater collection devices. The traditional sealing strip between the sink and the windshield is used to solve the sealing problem. Although the sealing strip is simple to install in the production process, there is a risk of the sealing strip and the windshield falling off, and the sealing performance can not be guaranteed.
