BERU electronically controlled diesel Instant Start System (ISS)

The BERU Diesel Instant Start System ISS of the second generation with new control unit and additional heating flange brings a further reduction in consumption and emission.

The BERU Diesel Instant Start System ISS of the second generation with new control unit and additional heating flange brings a further reduction in consumption and emission.

With the BERU Instant Start System, or ISS for short, the diesel engine starts as quickly and reliably as a petrol engine, even at extremely low temperatures. Thanks to performance-optimised glow plugs and an electronic control unit which regulates the glow time and voltage of every single glow plug individually. The ISS contributes to a permanently safe combustion process. It also largely prevents warm-up problems, irregular running of the engine, diesel nailing and excessive vibrations.


Technical features

  • Extremely short heating up time (up to 1,100 °C in 2 seconds!)
  • Safe start even at temperatures of -25 °C
  • Electronically controlled pre-heating, intermediate and post-heating
  • Immediate stable idling and clean load assumption
  • Minimised emission of pollutants and fuel consumption in the warm-up phase
  • Specially designed for diesel engines with direct injection
  • On board diagnosis compatible
  • Meets the latest requirements of the strict EURO pollution standard
  • In the ISS of the 2nd generation: suction intake air pre-heating by additional heating flange - further reduction in consumption and emission as well as optimisation of engine running and starting behaviour
