Adaptive Knock Controller KC100

Knock Control is an effective way to ensure your engines operational reliability is improved. This system is designed to allow operation at more advanced ignition advance timing without engine damage due to knock, providing better emissions, a potential reduction in fuel consumption and no loss in power.

The KC100 detects knock by using advanced digital signal processing to monitor the signals from one or more piezoelectric knock sensors suitably located on the engine. The KC100, programmed with engine specific measurement data, processes these knock signals and sends knock measurement data to the EC12 Engine Controller. The EC12 is programmed with engine-specific knock response data and with this the EC12 is able to adjust spark timing where required for each cylinder.

Applications include:

• CHP Engines
• Generator Set Engines
• Compressor Engines
• Commercial Vehicle Engines
• Forklift Truck Engines
• Passenger Vehicle Engines

As the KC100 adjusts spark timing on a cylinder-by-cylinder basis, this means that your engine can continue to operate at maximum efficiency. KC100 only makes adjustment where required, meaning that non-knocking cylinders can keep producing at maximum power, and knocking cylinders are adjusted to develop the maximum safe power whilst ensuring that no knock occurs.

Most inline engines will only require one or two knock sensors mounted on the engine block, as the KC100 is programmed to know when each cylinder can potentially knock. With a V-type engine, you will need a minimum of 1 knock sensor per engine bank, to accurately measure knock

Knock control can also protect your engine investment when the calorific content of the fuel changes. On an engine without knock protection, this can mean your engine can suddenly enter into a dangerous knocking condition, potentially leading to catastrophic failure. With the KC100 module this worry is removed as it will protect your engine from changing gas quality conditions.

The KC100 only measures and reports actual engine knock, and ignores the usual vibration signals associated with a reciprocating engine, such as valve chatter.

As part of a Total Engine Management package, the KC100 is designed to work alongside the Gill Instruments EC12 Engine Controller.
