Abstract

DC60 fuel injection device consisting of A fuel injection module that provides a function to absorb, pressurize and inject fuel through the reciprocating motion of the piston. And the control unit, which responds to the sensor output. For detecting the running state of the engine To feed the drive signal for the ball pump to the module Inject such fuel Depending on the operating status of the engine To make the vapors generated inside The cylinders may be discharged by flushing the injectors that do not lead to fuel injection. The control unit will inhibit the The injectors of the fuel injection module are flushed depending on the engine operating status by the fuel injection device sensors containing A fuel injection module that provides a function to absorb, pressurize and inject fuel through the reciprocating motion of the piston. And the control unit, which responds to the sensor output. For detecting the running state of the engine To feed the drive signal for the ball pump to the module Inject such fuel Depending on the operating status of the engine To make the vapors generated inside The cylinders may be discharged by flushing the injectors that do not lead to fuel injection. The control unit will inhibit the Flush the injectors of the fuel injection module depending on the running state of the engine by the sensor.

Claims (9)

1. The fuel injection device consists of: a fuel injection module with the function of suction, pressure and injecting fuel by the round-trip motion of the pump shaft. And the control unit, which responds to the output of Sensor for detecting the running state of the engine. To feed the drive signal for the pump ball For the said fuel injection module Depending on the operating state of the engine to cause vapors within the cylinder that may be discharged by cleaning the injectors. It will not lead to fuel injection where the control unit will de-purge the nozzles of the aforementioned fuel injection module depending on the operating status of that engine. By the said sensor 2. Fuel injection device according to claim 1, where the control unit will abolish the cleaning of the injectors of the said fuel injection module in case it measures the start of the engine with the input of the switch signal for starting the device. Start the engine 3. Fuel injection device according to claim 1, where the control unit will stop cleaning the injectors of the said fuel injection module in case it measures the voltage agreement. With power-volt stage input 4. The fuel injection device according to claim 1, where the control unit will de-purge the injectors of the said fuel injection module in case it measures the engine rotation with the signal input of the crank angle sensor. 5. Fuel injection device according to claim 1, where the control unit will de-purge the injectors of the said fuel injection module in case it measures the reference crank angle. For timing the ignition and timing of the fuel injection, which Necessary for controlling the engine With the input of the signal of the crank degree sensor 6. The fuel injection device according to claim 1, where the cleaning of the injectors of the said fuel injection module is canceled. In the event that the engine rotation speed exceeds the preset value for the deciding period Predetermined After the control unit is fed by electric power 7. Fuel injection device according to claim 1, where the cleaning of the injectors of the said fuel injection module will be abandoned. In the event that the power-volt stage is fed to the control unit. More than the preset value for the predetermined judgment period after the control unit is fed by power. 8.Fuel injection equipment in accordance with Claim 6 or Clause 7, where such predetermined interval is 100 milliseconds. 9. Fuel injection equipment according to claim No. 1 at which the control unit. Including the way to classify the rhythm For classifying each engine stroke based on data from the said sensor And where such fuel injection will be done immediately At the timing of the input signal, the degrees of crank later In the case of judgment, it is set to the quick start mode, even though the stroke classification path has not yet ended.
