BorgWarner is supplying its Pressure Sensor Glow Plug (PSG) for Volkswagen’s all new diesel engines starting with the 1.4-liter version and then adding the 1.6-liter and 2.0-liter versions later this year. Based on the new modular diesel engine system (MDB) (earlier post), the fuel-efficient, low-emission engines offer power ratings ranging from 55 kW (74 HP) to 140 kW (188 HP) and have been selected to be installed in several vehicles from VW, Audi, Seat and Škoda to meet Euro 6 emissions standards.
BorgWarner’s PSG combines a highly efficient glow plug to improve diesel engine cold starts with an integrated pressure sensor to improve engine efficiency. The sensor measures the rapidly changing cylinder pressure in the combustion chamber and reports the data to the engine control unit, establishing closed-loop control of engine pressure that allows the engine controller continuously to adapt fuel injection for each cylinder.
Featuring a robust steel heating rod and a piezo-resistive sensor, the PSG allows improved engine performance and efficiency.
In addition to its innovative PSG, BorgWarner supplies turbocharging technologies for the MDB as well.
