Mechanical Problems with the Use of Ignition-Improved Methanol in a Heavy-Duty Diesel Engine 872092

Ignition-improved methanol can be used as a fuel for heavy-duty diesel engines. However, endurance tests have revealed several fuel-related durability problems. Serious cavitation-induced erosion was observed in the injection system and extremely hard ceramic-like combustion deposits caused significantly increased wear.
Since solutions could be found for most of the problems encountered, the technical viability of ignition-improved methanol can be considered as sufficiently proven. However, further development work will have to be done to modify engine parts and materials and to adjust properties of lubricating oil to the requirements of operation on methanol fuel.
