Embodiment 2
Compression ignition internal combustion engine changes pressurized gas power plant method of work into, and its method is: the oil spout action adopting former compression ignition engine, and directly refluxed after the high pressure fuel pressure limiting export Injection Pump fuel tank; Utilize the fuel pressure hydraulic control after pressure limiting to control jet plug to inject high pressure gas in cylinder body simultaneously, promote cylinder interior pressure, promote piston movement.
The specific works method of this application example is: Injection Pump starts to export high pressure fuel at the compression stroke top dead center annex of compression ignition engine, this fuel oil arrives return pressure regulation pressure-limiting valve and the jet plug of hydraulic control respectively through injection tubing, and fuel oil guarantees that after the pressure limiting of return pressure regulation pressure-limiting valve injection tubing internal pressure is no more than the rated working pressure needed for the jet plug of hydraulic control and returns fuel tank through return tube; The jet plug of hydraulic control is driven jet by the fuel oil after pressure limiting, and pressurized gas enter cylinder and make cylinder pressure increase, and promotes piston movement; Compression ignition engine Injection Pump, along with piston movement, crank rotation, will stop oil spout immediately, and spray bar internal pressure declines, and it is jet that stopping closed by the jet plug of hydraulic control; In cylinder body, the continuation of gas overbottom pressure promotes descent of piston and completes expansion stroke; Each expansion stroke is this process of repetition from top dead center, and go round and begin again, compression ignition engine realizes periodic duty.
The utility model is also suitable in this model utility of multi-cylinder compression ignition engine.
The utility model does not affect and retains the working method that original compression ignition engine uses fuel oil whether simultaneously, makes to start function to switch under two kinds of working methods.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
