2. Maintaining internal combustion engines During maintenance routines, it is almost impossible to inspect internal components of the engine. This makes it difficult to detect damage and avoid catastrophic failures which result in higher costs for fleets.

3. Inspections of internal engine components Present method –Remove cover of cylinders or cylinder head. Disadvantages: –Unit out of operation throughout time of disassembly and reassembly of components –Higher maintenance costs: man-hours and equipment downtime –Higher risk of particle contamination within engine Solution to problem: Shell VideoCheck Digital Inspection

4. Latest-generation equipment Inspection equipment specially designed for use in industrial applications. A lens located on a probe sends the recorded images to a high-resolution monitor. Images are then recorded either as still images or movies with sound.

5. How does Shell VideoCheck work? The customer removes the injectors (diesel engines) or spark plugs (gasoline engines) so that the test can be carried out on the relevant truck(s) In a 720° crankshaft rotation, the following are inspected in the engine cylinders by the Shell VideoCheck operator: –piston crown –combustion chamber –cylinder wall –valve seats and heads Piston Cylinder Wall Minimum Combustion Chamber Valves & Cylinder Head Inspection Zones 1 3 2 4

6. How does Shell VideoCheck work? (2) Video images are recorded and interpreted by the Shell VideoCheck operator Report prepared for customer including findings and recommended remedial actions (if required) Effect of VideoCheck recommendation on fleet optimization monitored by customer & Shell

7. Features and Benefits of VideoCheck FEATURES Leading-edge technology Highly qualified staff Inspections of components which are hard to access Accurate diagnostics of equipment/ component condition Image recording BENEFITS Monitoring of operating efficiency Increased reliability Increased equipment uptime Efficient maintenance scheduling
