Parameters were controlled with software interface at the control room. Fuel temperature were measured by thermocouples and maintained at constant value with controller embedded in the user software. Ignition Delay was also controlled on the user software as CA value corresponding time between start of injection and start of com- bustion. The engine performance was investigated under many condi- tions and environments and the data was recorded digitally by various measurements. Results were processed results in the form of graphics to make them more comparable. The next stage involved the optimization of the engine parameters to get the optimum operating conditions.

This results shows that existent model can predict the values of ignition delay with approximately 1.5% error. Table 5
