For the past four years, the Co-Optimization of Fuels & Engines (Co-Optima) National Laboratory consortium has focused research efforts primarily on turbocharged (boosted) spark-ignition (SI) engines for light-duty vehicles. The report highlights researchers’ answers to three vital questions: What fuels do engines want?

The oil price shocks of the 1970s led the Brazilian government to address the strain high prices were placing on its fragile economy. Experiments have even shown that the evaporation of the water in the intake manifold acts as a charge air cooling, which improves the volumetric efficiency and thereby the overall efficiency of the engine.
