Abstract: An internal combustion engine 12 in which liquid fuel is introduced prior to the charge entering the combustion chambers is mounted in a vehicle having an air scoop 34 which acts as a source of ram air pressurised by the movement of the vehicle. The ram air is fed into the exhaust system by way of an isolation valve 36 which is opened only during engine deceleration modes and serves to reduce emissions of unburnt hydrocarbons and carbon monoxide caused by the fuel wetting the intake manifold.

Abstract: An intake system for an internal combustion engine has a plurality of intake tracts connected in use to extend from individual engine intake ports to a common plenum chamber and a common passage opening into the plenum chamber for supplying air to all the intake ports. The tracts are arranged to open into the plenum chamber in pairs associated with pairs of intake ports, each pair of intake ports having valve events which do not overlap. The ends of each pair of tracts disposed within the plenum chamber are arranged directly facing one another and are separated by a gap which is sufficiently wide to permit mass air flow between the respective tracts and the common passage but which is sufficiently narrow to couple most of any pressure wave energy emanating from one tract directly into the facing tract.

Abstract: A cylinder head gasket is described which also serves as an electrode of an ionization sensor. The gasket (16) has an electrically conductive surface portion (16c) which is electrically insulated from the cylinder head (14) and from the engine block (12) so that it may serve as an electrode of an ionization sensor. The gasket of the preferred embodiment is of five layer sandwich construction comprising two outer layers (16a, 16b) of soft metal capable of deformation under pressure to effect a gas tight seal with the block (12) and the cylinder head (14), a central core (16c) of electrically conductive material to serve as an ionization electrode and two layaers of ceramic material (16e, 16f) insulating the central core (16c) from the two outer layers (16a, 16b).

Abstract: An engine crankshaft has a crankpin that is radially slidably mounted relative to the crankshaft axis so that its axis can follow other than a circular path centered on the cranking axis. The mechanism includes at least one main bearing section with a stationary eccentric bearing surface, and at least one web fixed to the crankshaft and extending radially from the main bearing section. A housing is slidably mounted on guide surfaces on the webs for a sliding movement along the web, and has a crankpin secured thereto. The non-rotating eccentric bearing surfaces engaged by the housing force the housing to slide radially in and out along the web in synchronism with rotation of the crankshaft such that the distance of the center of the crankpin axis from the center of the main bearing section axis varies as a function of the angle of rotation of the crankshaft.

Abstract: An internal combustion engine has n member of cylinders, a piston in each cylinder connected to a crankshaft (2), each piston being in phase or out of phase with the others by A.degree. or a multiple thereof (A=720/n), cams for actuating inlet and exhaust valves to each cylinder, and a cam drive mechanism (5) which rotates the cams in phased relationship with the crankshaft (2) to open the valves in sequence for a desired angle of rotation of the crankshaft. The cam drive mechanism also includes means for combining the rotational movement of the cams with a phased oscillatory movement of the camshaft (3) and cams of variable amplitude about the axis of rotation at a frequency f times the crankshaft frequency so that over the period which the valves are opened and/or their timings variable, f has the following values:f=2n when the number of cylinders n=1;f=n or n/2 when n=2;and f=n/2 when n=3 or more. The selection of the frequency of the oscillations allows all the cams to be mounted on the same camshaft.
