A method for controlling exhaust gas emissions from an engine (16) includes extracting a light distillate fuel (Fd) from conventional gasoline or other liquid hydrocarbon fuel and supplying the engine with the light distillate fuel during an initial operation period of the engine. This reduces the oxidizable pollutants in the engine exhaust during a cold-start period before a catalytic converter (22) used to abate pollutants in the engine exhaust gases has not yet attained its operating temperature. After the catalytic converter (22) has been sufficiently heated, the fuel supply to the engine (16) is switched to gasoline or other liquid hydrocarbon fuel. Both the distillate fuel (Fd) and the liquid hydrocarbon fuel may be passed through a heated cracking catalyst bed (30) to crack the fuel fed to the engine.
A method for abating pollutants in the exhaust gas discharged from an internal combustion engine fueled by a liquid hydrocarbon fuel, the method comprising:
In an internal combustion engine apparatus comprising an internal combustion engine having a fuel intake, a fuel tank for storing a liquid hydrocarbon fuel and a liquid fuel transfer means including a fuel pump and a fuel line connecting the fuel tank in liquid flow communication with the engine for transferring the liquid fuel from the fuel tank to the engine, and an exhaust gas discharge pipe connected to the engine for discharge of exhaust gas from the engine, the improvement comprising:
