Above, left and right: The heart of D402 is the English Electric 16CSVT diesel engine. This engine was a further development of the 16SVT MK1 engine that had been used in the pioneer diesel locomotives No's 10000 and 10001. Dominating the photographs can be seen the eight cylinder heads that make up one bank of the V form engine. Photo © Andy Thomson |

This is a piston and connecting
rod (con rod) similar to the ones that are inside D402's engine. There
are 16 of these inside the English Electric engine arranged in two banks
of 8 in a V formation allowing them to drive a common crankshaft. In this shot the piston is at
the bottom with the metal seal rings clearly visible. These rings
ensure that the gap between the piston and the cylinder liner is
sealed preventing the atmosphere above the piston from escaping to
the area beneath it during the 4 stroke cycle of the engine. Photo © Andy Thomson |
| While D402 was still at Barrow Hill the opportunity was taken in 2002 to inspect the interior of the engine by using an Videoscope. In much the same way as in hospital examinations with an endoscope this allowed for images of the condition of the interior of the engine to be taken whilst the operator navigated the camera through the engine. The resulting images and information were compiled in to a report that can be accessed by clicking here. |
| The following photographs have been taken to show the damage caused by the ingress of water via the exhaust ports. Varying amounts of rust can be seen on the pistons, con rods and parts of the crankshaft itself. They also illustrate how the con rods are connected to the crankshaft. |
