Abstract

1409811 Supercharging I C engines G S POUIT 1 Nov 1972 [5 Nov 1971] 50330/72 Addition to 1354099 Heading F1B The parent Specification 1354099 claims a method of supercharging multi-cylinder I.C. engines wherein the depression which exists at the exhaust port of one of the cylinders, following the initial discharge of exhaust gas, is made to act at the intake port of a second cylinder out of phase with respect to the first by a half-cycle period and the present invention modifies this method by providing a heat storing element located in the exhaust space at a location where the exhaust gases are still at a temperature close to the temperature at which the gases flow out of the cylinder. The flattwin four-stroke engine shown in Fig. 1 has an inlet pipe 8 leading to the intake space 7 of each cylinder. A reverse flow restrictor 13 is positioned in the pipe 8 upstream of the mouth of a communicating passage 12 which leads to the exhaust port 10 of the other cylinder. A reverse flow restrictor 11 is positioned downstream of the outlet of the passage 12. An air inlet 18 in the passage 12 has variable area inlet ports 17 and is connected to the main throttle control of the engine through a one-way linkage which is effective to close the air inlet ports 17 against a spring which tends to open the ports. A dashpot controls the rate at which the spring opens the ports as the main throttle control of the engine is moved towards the open position. A spring-loaded non-return valve 37 is situated in the outlet of the passage 12 and complements the action of the reverse-flow restrictor at low engine speeds. Once the engine has reached a predetermined speed the valve 37 opens and then remains open, due to its inertia, throughout the four strokes of the cycle. In operation, the rarefaction which exists in the exhaust port 10 immediately after the initial discharge of gases from the cylinder 2, is communicated by the passage 12 to the intake pipe 8 and acts to supercharge the engine. A small quantity of fuel/air mixture enters the pipe 12, mixes with additional air which enters through the ports 17 and is directed into the space around the reverse flow restrictor 11, where it causes combustion of the carbon monoxide and unburned hydrocarbons in the exhaust gas, and also reduces the amount of nitrogen oxides in the gas. To promote this combustion, by increasing its temperature, the restrictor 11 is insulated from its support 29 by heat insulating washers 27, 28 and a sleeve 26. Combustion may also be assisted by coating areas 30 of the restrictor with catalytic material, or making these areas of catalytic material. Figs.4 and 5 (riot shown) illustrate the application of the invention to a two-rotor Wankel engine.
