摘要： A method is described for operating an engine (12) having an afterburner (16) and a catalytic converter (11) downstream of the afterburner (16). Sufficient excess fuel is introduced into the engine (12) to produce in the exhaust gases fuel constituents including unburnt hydrocarbons, carbon monoxide and hydrogen. Unburnt hydrocarbons are intercepted (10) upstream of the afterburner (16) so as to allow substantially only carbon monoxide and hydrogen to reach the afterburner (16). Sufficient additional air is introduced (30, 32) into the exhaust system to bring the composition of only the carbon monoxide, hydrogen and air stoichiometry or leaner than stoichiometry, the resulting concentration of hydrogen and oxygen in the mixture reaching the afterburner (16) being sufficient for ignition immediately after a cold start. By removing the hydrocarbons temporarily before the exhaust gases reach the afterburner (16), reliable cold ignition can be achieved with lower levels of fuel enrichment.

摘要： An engine is described having a combustion chamber with one or more intake ports and an injector for directing a spray or jet of fuel directly into the combustion chamber. The injector (60) is arranged in an injector chamber (54) distinct from the engine intake port or ports and separated from the combustion chamber by a poppet valve (56) that closes to isolate the injector (60) from the the combustion chamber during part of the engine operating cycle. The injector (60) is opened only at times that the poppet valve (56) is open and the spray of the injector is arranged to pass through the orifice of the open poppet valve (56) without wetting the walls of the injector chamber (54).

摘要： A phase change mechanism is described for varying the phase of an engine camshaft relative to the engine crankshaft. The mechanism comprises a drive member (10) to be connected to the camshaft drive, a driven member (14) to be connected to the camshaft, an eccentric (20) mounted for rotation about the axis of the camshaft, a coupling element (18) mounted about the eccentric and acting to transmit torque from the drive member to the driven member, and drive means (22) for rotating the eccentric to move the coupling element (18) relative to the drive and driven members (10, 14) and thereby vary the phase between the drive and driven members. To reduce noise caused by chattering of the coupling element (18) about the eccentric (20), means such as springs (19, 19') are provided for applying a constant additional force to the coupling element while the phase change mechanism is in rotation, the force acting in a direction transverse to the line of action of the reaction force reversals acting on the eccentric (20).

摘要： An internal combustion engine is described having an intake valve (12) and an injector (40) for directing a metered jet of fuel into the intake port. To improve charge preparation, a fluidic ejector or jet pump (32) directs a jet of air at the back of the intake valve (12). The mass flow of air directed at the valve is significantly greater than the mass flow through the supply jet of the ejector, the ejector setting up air recirculation within the intake port to encourage full evaporation while the intake valve (12) is closed.

摘要： An internal combustion engine is described comprising a cylinder having an intake valve (14), and two manifolds having branches (22, 32) that are configured to supply two gas streams to the intake valve of each cylinder. The two streams enter the cylinder separately through the valve (14) so as to produce a stratified charge within the engine cylinder. The first manifold (24) supplies a metered quantity of air within which the fuel to be burnt is dispersed and the second manifold (34) supplies stratification gases. A non-return valve (23) is arranged in each branch (22) of the first manifold to permit gas flow in the branch only in the direction towards the intake valve (14).

摘要： An exhaust system for an internal combustion engine, comprises a down pipe (14) for connecting an exhaust manifold of the engine to a main catalytic converter and a supplementary catalytic converter arranged in a path connected in parallel with the down pipe (14). The supplementary converter has an annular passage defined between inner (18) and outer tubular (16) walls which contains a catalytic matrix (20) and communicates with the interior of the down pipe (14) at its upstream and downstream ends. A second passage (20) also communicates with the interior of the down pipe (14) at its upstream and downstream ends and an obstruction (34) obstructs the down pipe (14) between the upstream and down stream ends of both the first and the second passages. A flow control tube (32) is movable relative to the down pipe (14) between a first position in which exhaust gases can flow from the down pipe into the first annular passage and return to the down pipe downstream of the obstruction (34) after passing through the catalytic matrix (20) and a second position in which exhaust gases can flow from the down pipe (14) into the second passage (22) and return to the down pipe downstream of the obstruction without passing through the catalytic matrix (20).

摘要： A reciprocating piston internal combustion engine is disclosed having an eccentric (16) arranged between each piston (10) and its connecting rod (12) and a spring (22) for applying a biassing torque to urge the point of maximum eccentricity on the eccentric (16) to a rest position lying on a line transverse to the longitudinal axis of the connecting rod. The eccentric is free to oscillate about the rest position as a result of the forces acting between the piston (10) and the connecting rod (12) during engine operation and this varies dynamically the instantaneous effective length of the connecting rod.

摘要： An internal combustion engine is described having a crankshaft, a camshaft (16) driven by the crankshaft through a drive wheel (10) at half the crankshaft speed and at least one cam on the camshaft (16) for actuating a spring biased poppet valve of the engine. To achieve variable event timing, a lost motion coupling (10, 20, 14) is arranged between the drive wheel (10) and the camshaft (16). During the opening of the valve the camshaft (16) rotates at substantially the same speed as the drive wheel (10) but during the closing of a valve, the camshaft (16) is accelerated by the valve spring to lead the drive wheel and thereby reduce the duration of the valve event. It is alternatively possible to collapse the opening phase of the valve event rather than the closing phase by reversing the operation of the coupling.
