Abstract: A four stroke internal combustion engine has a cylinder (13) with first inlet port 1 directed to discharge in a direction tangential to the periphery of the cylinder (13) and a second inlet part directed to discharge towards the centre of the cylinder (13). A first injector has a spray targeted symmetrically on the up-stream side of a head of a first inlet valve (7) and a second injector has a spray targeted towards the side of a head of a second inlet valve (8) which is closest to the centre of the cylinder (13). There is also provided means by which more exhaust gas recirculation can be supplied to the first inlet port (1) than the second inlet port (2) and a means by which the flow rate through the second inlet port (2) can be restricted.

Abstract: A thermal actuator includes a first arm having a proximal end and a distal end, a second arm, parallel to the first arm, having a proximal end and a distal end, and a third arm arranged between and parallel to the first and second arms, the third arm having a proximal end and a distal end. The third arm has at least one portion at the distal end of the third arm having a width that is substantially larger than a width of the first arm and a width of the second arm. The distal ends of the first, second and third arms are coupled together to form a distal end of the thermal actuator, and the first, second and third arms preferably are made of a single material. When the proximal end of the third arm is coupled to ground and current is applied to the proximal end of the first arm, the distal end of the thermal actuator moves and applies force in a first direction, and when the proximal end of the third arm is coupled to ground and current is applied to the proximal end of the second arm, the distal end of the thermal actuator moves and applies force in a direction opposite to the first direction. A number of thermal actuators can be arranged in an array. The thermal actuator or array of thermal actuators can be coupled to an applicator.

Abstract: A system is provided for rapidly changing the flow of recirculated exhaust gas to each cylinder (61-66) of an internal combustion engine operating on diesel fuel or other fuels. The system preferably includes an exhaust gas recirculation line having an exhaust gas recirculation pump (146) along with a reservoir and cooler (152) for storing a desired volume of recirculated exhaust gas. Recirculated exhaust gas is preferably supplied from the reservoir to each cylinder of the associated engine through respective recirculated exhaust gas conduits (191-195). A metering valve (161-166) is preferably disposed within each recirculated exhaust gas conduit immediately adjacent to each cylinder. The metering valves provide uniform distribution of recirculated exhaust gas to the respective cylinders and allow the system to rapidly change the flow of recirculated exhaust gas to each cylinder. The system provides recirculated exhaust gas at a point close to the combustion chamber where it is needed for effective reduction of undesirable NOx emissions.
