    Abstract: A method of reducing the light-off time of a catalytic converter comprising exposing the matrix of the converter to an alternating magnetic field or to electromagnetic radiation having a frequency such that the washcoat and the catalyst particles supported by the matrix are heated to the light-off temperature without a corresponding increase in the temperature of the entire matrix. The catalytic converter includes a matrix formed in two or more parts, of which the downstream parts are conventional. The upstream part of the matrix consists of a honeycomb made of a material which does not absorb microwave energy, is coated with a washcoat dispersed with catalyst particles which does heat up when exposed to microwave energy, and is enclosed in a waveguide having perforated walls through which exhaust gases can flow.

    Abstract: A phase change mechanism for a camshaft of an internal combustion engine comprises a drive member to be connected to the camshaft drive train, a driven member to be connected to the camshaft, a coupling element interposed between, and movable relative to, the drive and driven members, and means connecting the coupling element for rotation with the drive and driven members in such a manner that the phase of the driven member relative to the drive member is dependent upon the position of the coupling element. The connecting means is designed to permit the coupling element to move between two stable end positions lying on a line generally perpendicular to the axis of rotation of the phase drive and driven members, and a reaction member is connected to the coupling element by a cranking means which causes the coupling element to move from one stable end position towards the other in response to the application of a torque acting to vary the speed of rotation of the reaction member relative to the drive and driven members.

A sensor is provided to produce a signal representative of the burn quality and the fueling timing is controlled in dependence upon the output signal of the sensor so as to optimize the charge stratification within the combustion chamber.

    Abstract: The invention is concerned with a desmodromic valve operating mechanism, i.e. one in which the valve is mechanically closed instead of relying on the action of a spring. The valve operating mechanism comprises a cam 20 driven in synchronism with the engine crankshaft. A cam follower 18 is acted upon by an opening profile 22 of the cam 20 and serves to move the valve 10 in an opening direction. A movable closing member 26 has two profiles 24, 28. The first profile 24 interacts with the cam 20 and the second 28 with the cam follower 18. Closure of the valve is effected by the opening profile 22 of the cam 20 acting on the first cam profile 24 of the closing member 26 to move the closing member 26 in such a direction that the second cam profile 28 of the closing member 26 acts on the cam follower 18 to close the valve 10.

    Abstract: The invention relates to an ignition system in which a parameter of the charge in a cylinder prior to ignition is measured in order to predict the burning characteristics of that charge and the timing of the spark for igniting that charge in the same cycle is varied in dependence upon the measured parameter in such a sense as to reduce cycle to cycle variations in the engine output torque. A hot film anemometer integrated into the spark plug provides a measurement of the charge velocity, this being one parameter which can predict the burning rate of the charge.

    Abstract: A method is described of operating an internal combustion engine burning a fuel containing carbon and hydrogen, to provide a flame in the exhaust system to heat a catalytic converter or burn off the soot in a particulate filter trap. The method involves reducing the intake throttle opening during deceleration mode below the throttle opening for the steady speed idle position to create a proportion of combustible gases in the exhaust gas stream. By ensuring at the same time the presence in the exhaust gas stream of additional air, an ignitable mixture is produced which is ignited to burn as a flame in an afterburner chamber of the exhaust system. By selecting deceleration periods to enrich the mixture excessively in this manner, adverse effects on drivability go unnoticed.
