Recommissioning the Lotus Experimental Free-Piston Engine

Now that the Free-Piston engine is back at the ThinkTank, the electrical drive to the main crankshaft servo will be re-commissioned by Control Techniques Ltd.

The Engine has been away for a while having a new linear electrical motor-generator fitted, and is now ready for electrical re-comissioning before we move it into it’s test-cell in the new School of Engineering building.

The engine is unique, in that it allows piston trajectory control for experimentation on both conventional (with crankshaft) and free-piston (linear electrical machine, no crankshaft) operation.

After re-commissioning and installation in the new building, Prof Stewart will be continuing research into fundamental combustion, multi-fuel operation with variable compression ratios and free-piston operation in collaboration with Dr Jill Stewart, Reader in Thermofluids.
