The use of a fast pyrolysis oil - Ethanol blend in diesel engines for chp applications

More recently, the four cylinder, 48 kW diesel engine has been modified to enable fueling with FPBO. This engine can be seen as a prototype for a commercial CHP unit (100 kW-1 MW electrical output). The unit was successfully commissioned and initial tests are in line with the 1C experiments. Due to a lower calorific value, the volumetric fuel consumption is significantly higher in case of FPBO. However, the overall electrical efficiency is very similar to diesel.
