摘要： An accurate method of determining the power developed by selected cylinders of a multiple cylinder engine is based on the concept of controlling engine rpm for test purposes by adjusting the load on the engine instead of controlling speed by adjusting the fuel rate as is commonly done in normal engine operation. The method may be utilized for evaluating cylinder performance and for accurately balancing the output of the individual cylinders. It is particularly useful in railroad applications where the engine operates a generator that produces electric power and the system is provided with dynamic braking grids, which can be utilized as resistor grids for load testing the engine. However, the method is also applicable to other engines and other engine arrangements where engine power may be absorbed by a generator or dynamometer for controlling the load for test purposes.

摘要： A diesel engine emission control system which optimizes fuel injection timing over a range of air temperatures, air pressures, and engine air flow rates. The emission control system includes a control module interfacing with a fuel injection timing module which in turn interfaces with an engine fuel injection system having fuel injectors. The control module receives data from an air temperature sensor, an air pressure sensor, and an engine boost pressure sensor. The control module determines air density and the air flow rate through the engine to determine optimal fuel injection timing. The injection timing information is relayed to the injection timing module which alters the timing of the fuel injectors to operate the engine at a maximum efficiency possible within applicable emission regulation limits.

摘要： An electronically-controlled air injection system implemented in three different embodiments with respect to each cylinder. A first embodiment includes a T-adapter, an air solenoid, a fuel injector, and a control unit. The T-adapter receives pressurized fuel and pressurized air from an air solenoid, and outputs these to the fuel injector. The air solenoid controls the flow of air to the fuel injector via the control unit. The second embodiment includes a modified fuel injector, an air solenoid, and a control unit. The fuel injector is modified by forming therein an air passage and a communicating sac, wherein the sac communicates with the fuel valve. Compressed air is supplied through an air solenoid to the air passage. The third embodiment includes a modified cylinder head, an air solenoid, and a control unit. Compressed air is supplied through an air solenoid to at least one combustion chamber cylinder port in the cylinder head.
