Bosch Engineering K.K.

A car manufacturer wishes to produce a small series of diesel models of its current of four-cylinder spark ignition engine vehicles. Instead of using the four cylinder spark ignition engine, a diesel engine produced by another manufacturer is to be used. It is a challenging task for the team at Bosch Engineering K.K. because fitting the engine into a different vehicle generates completely different data for the electronic drive control system, which in turn defines the desired values for fuel volume, turbo pressure, injection timing etc.

All parameters of the control system must therefore be adjusted and optimized to conform with the new engine environment. Many of the approx. 5,000-8,000 parameters are interdependent – such as the idle RPM and engine temperature, the fuel volume and accelerator pedal position, or the RPM and turbo pressure. Determining and defining all the ideal parameters is called application.

These complex tasks are solved on the dyno and directly in the vehicle. The interface between computer technology and modern automobile mechanics requires both precision and a feeling for each vehicle.

After successful application, a CD-ROM with the new control data is sent to the manufacturer, who can now begin production manufacturing of the diesel edition: The new engine runs smoothly, consumption and performance are optimized and all legal requirements are fulfilled – without any changes to the mechanical hardware.
