  • Engine control with fuel quality sensor
    Patent number: 7210455
    Abstract: A system is described using a fuel quality sensor for controlling various aspects of engine operation. In particular, an acoustic wave sensor is utilized to measure viscosity and density of gasoline fuels. This measurement is utilized to predict engine combustion quality during an engine start. Based on the prediction, the method adjusts engine operating parameters (such as fuel injection amount and ignition timing) to achieve improved vehicle driveability and engine combustion.

  • Method of improving the operational capacity of three-way catalysts
    Patent number: 4024706
    Abstract: A method is disclosed for widening the range of air-fuel ratios over which three-way catalysts having an oxygen storage capacity are operative. Three-way catalysts are operative when new both in oxidizing at least 80% of the unburned hydrocarbons and carbon monoxide and in reducing 80% of the oxides of nitrogen contained in an exhaust gas stream delivered to the catalysts from an engine. In general, the method is conducted by supplying to the engine to be burned therein an air-fuel mixture in which the fuel to air ratio is varied from a rich condition in which more fuel is present than air to burn it to a lean condition in which less fuel is present than air to burn it. The air-fuel ratio is displaced equal amounts to the rich and to the lean sides from a stoichiometric condition.
