- Oil line reversing control from fuel injection pump 27-7, oil tee 27-9, oil passage reversing valve 27-10, pump injector rocker push rod change valve 27- ⁇ , fuel pressure relief Pressure valve 27- ⁇ , cylinder injector 27- ⁇ , spoiler chamber micro-injector 27- ⁇ .
- Circuit commutation control by electronic control unit 27-7, electric tee terminal 27-8, oil passage reversing valve 27-10, cylinder injector 27- ⁇ , spoiler micro-injector 27 - ⁇ and other components.
- Mechanical pump injection engine Firstly, replace the thrust guide block 16-9 of the pump injector rocker push rod change valve with the clip type telescopic guide block, so that the main and auxiliary push rods simultaneously pump fuel in the normal state.
- the oil supply pipe is connected to the oil tee pipe.
- the torque device or the microcomputer command pump injector rocker push rod change valve and the oil electric passage reversing valve act simultaneously, so that the pump injector rocker push rod change valve main Pusher 16- ⁇ Stop pump oil, oil passage reversing valve cuts off oil to cylinder pump injector.
- the spoiler micro-oil injector is continuously injected to achieve the effect of circulating exhaust gas turbulence purification.
- Electronically controlled injector type engine The connection to the oil circuit is the same as that of the mechanical direct injection oil type engine. After the circuit for the injector is connected by the electric tee 27-8, a circuit is directly connected to the spoiler micro-injector 27_ ⁇ . When the engine enters the turbulent flow purification combustion state, the torque device or the microcomputer commands the oil passage directional control valve to operate, and the cylinder injector is cut off and oiled.
- Electronically controlled pump injection type, electronically controlled common rail pump injection type engine The connection of the oil circuit is the same as that of the mechanical pump injection type engine, and the circuit connection is the same as that of the electronically controlled injection type engine.
- the control when entering the turbulent flow purification combustion is also the same as the two types of engines.
- the vehicle and the marine engine which have been improved by the technique of the present invention, are subjected to two operation modes, which are controlled by selection switches in the above systems.
- the full load of the ship is driven for a long time in the deep water jet, and other conditions requiring large engine load for a long time, the full-cylinder operation state is selected.
- the circuits such as the torque detecting system and the two-burning system are all cut off and the control is exited, but the spoiler combustion system does not stop.
- the variable cylinder operation state is selected, and the torque detection system and the secondary combustion system at this time enter the control operation. This achieves a power mode dual mode effect.
- the system is compatible with all reciprocating piston two-stroke and four-stroke, traditional and modern petrol engines and diesel engines.
- the automatic stop cylinder in the vehicle is controlled directly by the torquer.
- the gas is switched, the spark plug is cut off, and the fuel injector is cut off.
- a vacuum negative pressure inside the cylinder is generated in the intake stroke, and a vibration braking phenomenon occurs, which is specially designed to switch a small amount of air supply to the cylinder, so that the cylinder after the cylinder is fired is inflated. Insufficient, which in turn reduces power loss during compression strokes.
- the system is a flexible-type cylinder deactivation method, the increase in vibration is not too large.
- Gas distribution switching spark plug power off by oil passage directional control valve 28-7, intake switching valve 28-8, exhaust switching valve 28-9, auxiliary air intake small pipe 28- @ ⁇ , auxiliary exhaust small pipe 28 - ⁇ @ ⁇ .
- the intake switching valve closes the air intake port, and the auxiliary air intake small pipe is opened, and a small amount of air is supplied to the cylinder along with the valve phase of the original machine, and the oil and electricity passage
- the reversing valve de-energizes the spark plug.
- the exhaust switching valve closes the main exhaust passage, and the sub-exhaust small duct discharges the pure air after the cylinder is broken.
- the oil-electric passage reversing valve performs oil cut-off and fire breakage of the injector, and the spark plug is de-energized.
- Re-use diesel engine automatic stop cylinder control system As shown in Figure 29, it is composed of electrical control and gas distribution switch injector oil cut.
- Gas distribution switch injector oil cut consists of intake switching valve 29-8, auxiliary air intake small pipe 29- ⁇ , oil and gas passage reversing valve 29-7 and so on.
- the intake switching valve closes the intake port, and the sub-inlet small pipe or bypass pipe is opened to supply a small amount of pure air to the cylinder.
- the oil and gas passage reversing valve cuts off the fuel injector.
- an oil passage reversing valve is implemented to shut off the fuel injector.
