Optical Spark Ignition Research Engine Test Rig
(Product Code: R&DU07)
Description of the Individual Engine Components
There are several different ways of visually accessing the combustion chamber in an internal combustion engine. Optical access is provided through a 15mm length fused silica liner and a sapphire window in the piston crown. An extended piston allows a 45° mirror to be located between the upper and lower piston crowns allowing illumination or viewing into the cylinder from below. A maximum engine speed of 1500 rpm can be achieved through the use of lightweight materials for the piston components and the use of primary and secondary balance shafts in the crankcase. The piston is manufactured from aluminium while the piston crown is made from titanium, chosen due to the similarity in thermal expansibility between titanium and sapphires
