The Allen Diesel Engine
The Allen diesel engine is one of four originally installed
at Kew Bridge. The engines were installed to meet extra demand
during the sumer months and, along with electrical pumps,
to replace the steam engines when they retired during the
1940s.
Our engine is a three cylinder, 4-stroke engine, coupled
to a centrifugal pump. It has many feaures in common with
more modern diesel engines, including a fully enclosed crankcase,
but still has an external flywheel.
