Abstract
941,220. Charging two-stroke and four-stroke engines; valves. SULZER FRERES S.A. June 1, 1961 [June 15, 1960], No. 19867/61. Heading FIB. In a method of operating a multi-cylinder engine supercharged by exhaust-gas turbosuperchargers and having cylinders arranged in at least two groups which have a common scavenging or charging air receiver and each have their own exhaust-gas turbine driving a supercharger each supercharger being in parallel with or followed by at least one engine driven auxiliary pump, in the event of a breakdown,of one of the turbosuperchargers different groups are operated at different power outputs by reducing the fuel charge of the affected group to suit the capacity of its auxiliary pump or pumps and isolating this group by partitioning the air receiver so that it receives air only from its auxiliary pump or pumps, thereby allowing the remaining cylinders to continue to operate at their full mean effective pressure. The term "auxiliary pump" includes the underside of the piston when used for aiding scavenging, or a separate blower or pump for scavenging in the case of a two-stroke engine or for changing the air charge in the case of a four-stroke engine. During normal operation of the two-stroke engine shown in Fig. 1 plates 17 and 18 are omitted and all openings 12 are sealed, so that the two turbosuperchargers 4 operate in parallel to supply compressed air, cooled in coolers 7, into a common receiver 8. The air passes from the receiver 8 through non-return valves 9 into separate scavenging chambers 10a, Fig. 2, interconnected with chambers 10 where it is further compressed by the undersides of the pistons and passes through scavenging ports 21 to the combustion chambers. The combustion products pass through conduits 11, past rotary exhaust control valves 22, to operate the turbines 5. If one of the turbosuperchargers fails covers 14 are removed from that part of the receiver 8 associated with the faulty turbosupercharger, and this part of the receiver is isolated from the other part by inserting plates 17, 18 as shown in Fig. 1. The undersides of the pistons of the group associated with the defective turbosupercharger draw in air through the openings 12 to provide limited scavenging of their cylinders, thereby allowing this group to operate at a reduced power output whereas the other group produces normal power. The fuel charge of the low power group is reduced according to the capacity of the auxiliary pump as by modifying the fuel linkage mechanism by inserting pivot pins in holes provided for that purpose. Specification 815,387 is referred to.
