IDENTIFICATION Engine Conversions and Modifications General View of the MBE 900 Engine The function and safety of the engine could be affected if unauthorized modifications are made. Detroit Diesel will not accept responsibility for any resulting damage. The 2004 on-highway MBE 900 engine is equipped with an Exhaust Gas Recirculation (EGR) system to reduce engine exhaust gas emissions in accordance with EPA regulations. See Figure 5 for a right front view of the MBE 900 EGR engine, 6-cylinder model, and Figure 6 for a left rear view. Tampering with the fuel injection system and engine electronics could also affect the engine's power output or exhaust emission levels.
Compliance with the manufacturer's settings and with statutory environmental protection regulations cannot then be guaranteed. The off-highway engine used in construction and industrial applications does not have an EGR system. See Figure 7 for a front view of the MBE 900 non-EGR engine, 6-cylinder model, and Figure 8 for a side view of the 6-cylinder model (right-hand side). See Figure 9 for a front view of the MBE 900 non-EGR engine, 4-cylinder model, and Figure 9 for a rear view of the 4-cylinder model. 14 All information subject to change without notice.
