摘要： Systems and methods for identifying alcohol content of a fuel in an engine. In one example approach, a method comprises adjusting fuel injection to the engine based on fuel alcohol content identified from crankshaft acceleration. For example, the crankshaft acceleration may be generated by modulating an air/fuel ratio in a selected cylinder across a range of air/fuel ratios while keeping the engine at stoichiometry.

摘要： A method and system for fuel vapor control in a hybrid vehicle (HEV). The HEV fuel vapor recovery system includes a fuel tank isolation valve, which is normally closed to isolate storage of refueling from storage of diurnal vapors. The method for fuel vapor control includes selectively actuating the fuel tank isolation valve during interrelated routines for refueling, fuel vapor purging, and emission system leak detection diagnostics to improve regulation of pressure and vacuum the HEV fuel vapor recovery system.

摘要： A system for managing fuel-vapor emission from a fuel tank of a vehicle using a vortex-effect flow separator coupled in the fuel-vapor purging system of the vehicle. The warmer-flow outlet of the separator is coupled to the engine intake, and the cooler-flow outlet is coupled to the fuel tank. In this way, less fuel vapor is delivered to the engine intake.
