International pressure to reduce transportation carbon dioxide emissions is providing a driving force favoring use of high efficency diesel engines. Environmental groups question increasing use of diesel engines. Laboratory experiments indicate that the diesel engine with new control technologies, in conjunction with very low sulfur diesel fuel, can attain very low emission levels comparable to those of conventional gasoline engines. Cost-effective emissions control can be achieved with three-pronged systems approach, i.e., simultaneously addressing fuels formulation, in-cylinder combustion control. |
