US – The company’s pressure sensor glow plug (PSG) will initially feature on Volkswagen’s new 1.4-litre diesel engine, followed later this year by the 1.6-litre and 2.0-litre models. Based on the new modular diesel engine system (MDB), the engines will feature on VW, Audi, Seat and Skoda vehicles.
“BorgWarner’s advanced diesel cold-start technology contributes significantly to a cleaner combustion process,” commented Brady Ericson, president and general manager, BorgWarner Emissions Systems. “BorgWarner is the first manufacturer to produce the PSG in series production.”

The PSG features a steel heating rod and a piezo-resistive sensor. The glow plug improves diesel engine cold starts with an integrated pressure sensor to boost 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 which allows the controller to continuously adapt fuel injection for each cylinder.

In addition to the PSG, BorgWarner is supplying turbo-charging technologies for the MDB.
