    Abstract: A method of controlling the mass of air and fuel delivered to an internal combustion engine per cylinder per cycle by first determining the required fuel per cycle for the existing engine operating conditions, and then setting the air supply to the engine to provide the required air/fuel ratio for the determined fuel per cycle requirement. Thereafter, determining the actual air supply to the engine, and adjusting the fuel per cycle so the actual air/fuel ratio is greater or less than predetermined limits of the required air/fuel ratio. A look-up map can be provided in an electronic engine management system with preset air/fuel ratios against engine speed and load. The map is arranged with the predetermined limits of the required air/fuel ratio selected to prevent a specific condition such as engine misfire or for catalyst and/or emission considerations.

    Abstract: A method of control of the supply of lubricating oil to a two stroke cycle internal combustion engine comprising supplying fuel to a fuel injector from a fuel reservoir having a fuel capacity greater than the maximum fuel requirement of the engine per cycle. The fuel in the reservoir being maintained at a substantially steady pressure. Delivering oil to the engine by a positive displacement pump having a delivery capacity per pump cycle greater than the maximum oil requirement of the engine per cycle. The oil pump being activated in response to the consumption of fuel from the fuel reservoir to maintain a substantially uniform predetermined ratio between the fuel consumption rate and the oil delivery rate.

Along this axis the block (9) has a plurality of aligned recesses in which are located bearing members (24) for the power valves. Bores (25) in each bearing member (24) are axially aligned and the bearing members (24) immobilely retained in the aligned recesses by assembly of the exhaust manifold (16). Spigots on the power valves are received in the bores (25) and coupled together so that the power valves rotate in unison.

    Abstract: A method of operating a two stroke cycle crankcase scavenged internal combustion engine, comprising selectively delivering exhaust gas from a location downstream of the engine exhaust port to the engine crankcase to be delivered together with air in the crankcase to the engine combustion chamber. The quantity of exhaust gas delivered to the crankcase each engine cycle is controlled according with engine operating conditions and the rate of supply of exhaust gas to the crankcase is controlled relative to engine operating conditions such as by an ECU managed valve that responds to engine operating conditions such as load, speed and temperature. The exhaust gas is admitted to the crankcase during a period when the pressure in the crankcase is below that of the available exhaust gas.
