SC Hurricane Common Rail Diesel Engine Management System

Modern common rail diesel engines are very complex and their engine management systems are critical for the engine to operate. Without the engine control unit (ECU) a common rail diesel engine will not start and run. The technology is very different to that of gasoline engines. The fuel pressure in the diesel common rail ranges from 200 to 1600 Bar, varying dynamically as the engine speed and load changes, supplied by an engine mounted electronically control mechanical pump. This compares to just 3 Bar for a typical gasoline engine from its electric pump. Fuel injection timing and quantity is critical in the diesel with up to 5 separate injection events per cylinder per cycle. Each of these injections must be individually timed to less than ΒΌ crankshaft degree. To enable this precise control, the injectors are driven with up to 100 Volts and 20 Amps.


The ECU in a mass production common rail diesel vehicle is dependent on many other modules in the car. These modules communicate with each other on several networks, to share information from various sensors around the engine, transmission, chassis and cabin. Without these other modules, the ECU will not function. The resulting situation is that it is virtually impossible to take a common rail diesel out of a production vehicle and use it in another application.

That is until now, using Specialist Components unique Hurricane stand-alone programmable common rail diesel engine management system. Nothing else is needed to run the engine, as the Hurricane system is completely stand-alone.

The Hurricane system (consisting of the SC Typhoon or Tornado ECU and an external SC Injector Driver Module - IDM) enables simple installation of common rail engines. A PC can be connected to the Hurricane system via SC's bespoke USB interface and software, enabling easy visual diagnostics of all the engine sensors and actuators.

Both Piezo and Solenoid common rail diesel injectors can be used with the Hurricane system and the ECU is capable of driving up to 12 cylinder engines by using multiple driver modules.

Like all SC products, the Hurricane system has been 100% developed and designed by SC's engineers at their base in Norfolk, UK. It is available to OEM customers directly from us, for trade and retail customers from our UK distributors Simtek UK or together with a new Ford common rail diesel engine from Power Torque Engineering Ltd.

Please contact us for further information about this exciting unique product, OEM and trade enquiries are welcome. We are able to provide bespoke engne management systems for most common rail diesel applications, including automotive, industrial, marine and aerospace.
