THE INFLUENCE OF DIESEL ENGINE AUTOMATION ON PERFORMANCE, MAINTENANCE AND TBO'S

Two marine Diesel engine functions are mainly automated today: monitoring of conventional measurement signals and the logical sequence of orders to manoeuvre the engine. In addition, wearing parts are condition-monitored on an increasing scale with a view to optimally cost-effective exchange of these parts. Apart from reliable sensors, this necessitates sophisticated data processing by the engine builder, this being the only means of furnishing the engine operator with economical maintenance schedules based on the large number of data obtained. The costs involved in extensive measuring systems will not be fully justified unless these systems enable the engine to adjust itself to changes in ambient and operating conditions, the aim being maximally cost-effect service and low component failure rates. Two examples are given to prove this point: Electronic injection capable of straightforward injection parameter variation permits matching the various fuel grades within a wide service range. Especially in the case of engines developing a high power output per unit of piston area, the variable-geometry nozzle ring of the turbocharger favourably influences the operating values at part loads and thus reduces the thermal loading of the components. Only the self-adjusting Diesel engine will afford optimum operational reliability and component TBOs. Order from BSRA as No. 54,908.
