METHOD OF OPERATING AN ENGINE ASSEMBLY

A method of operating a compoundable engine (10) that includes a turbine (22) having a turbine shaft (26) and an intermittent internal combustion engine (12) having an engine shaft (14). The engine shaft (14) is rotated at a first rotational speed. The turbine (22) is driven by exhaust gases of the...

Zusammenfassung:A method of operating a compoundable engine (10) that includes a turbine (22) having a turbine shaft (26) and an intermittent internal combustion engine (12) having an engine shaft (14). The engine shaft (14) is rotated at a first rotational speed. The turbine (22) is driven by exhaust gases of the intermittent internal combustion engine (12) to rotate the turbine shaft (26) while the engine shaft (14) rotates independently from the turbine shaft (26). A rotatable load (L) is driven with the turbine shaft (26). A rotational speed of the engine shaft (14) is increased from the first rotational speed until the turbine shaft (26) reaches a predetermined rotational speed. After the turbine shaft (26) has reached the predetermined rotational speed, the rotational speed of the engine shaft (14) is adjusted until the turbine shaft (26) and the engine shaft (14) are drivingly engageable with each other, and the turbine shaft (26) with the engine shaft (14) are engaged such that both are in driving engagement with the rotatable load (L).
