摘要： PURPOSE:To aim at an increment of pressure-feed power in a fuel injection pump, by controlling a valve, installed in a bypass passage of a fuel injection nozzle, and a regulator lever of the fuel injection pump according to engine speed and load. CONSTITUTION:A valve 21, installed in a bypass passage 18 of a fuel injection nozzle 12, is connected to a linear solenoid 23 via a rod 22, and the upper end of a fuel quantity regulator lever 5 of a fuel injection pump 2 is made contact with a linear solenoid 7. According to engine speed and load, both these solenoids 23 and 27 are driven, controlling the valve 21 and the lever 5. With this constitution, even in times of low speed and low load, the fuel injection pump 2 is operatable for its full load operation so that pressure-feed power in the fuel injection pump 2 is well improved, thus fuel atomization is improvable.

摘要： PROBLEM TO BE SOLVED: To shorten an injection time by increasing a flow rate of injecting fuel without increasing a demand pressure reducing amount of the pump chamber of a pressure accumulation type fuel injection valve for an internal combustion engine and increasing size. SOLUTION: A diameter of a push rod 1 is set to a value lower than that of the guide part 26 of a nozzle needle 9 or the sectional area of the push rod 1 is reduced to a value lower than that of the guide part 26, and set to a value higher than a difference between the sectional area of the guide part 26 and that of a sheet part 32. Since this constitution reduces a stroke volume of the push rod 1, a demand pressure reduction amount of a pump chamber 5 to hold the nozzle needle 9 in an opening state is decreased and the load of an actuator 4 is decreased. When the output of the actuator 4 is the same, a lift amount higher than that of the nozzle needle 9 is obtained and a sheet diameter is expanded, whereby an injection period is shortened through the increase of a flow rate of fuel. The nozzle needle 9 may be formed integrally with the push rod 1.

摘要： PROBLEM TO BE SOLVED: To provide a transfer fixing device for a four-drive vehicle which can further reduce vibrations transmitted to a vehicle body. SOLUTION: Since a fixing part 42 provided on a top end 40 separated a predetermined distance from a part joined to a transfer axle 26 which tends to be vibrated in a transfer 28 is fixed to the middle position 50 of an engine side member 44 of a rear engine mount 18 having fully large rigidity to fix a heavy horizontal engine 24 to a vehicle body, relative vibrations of the horizontal engine 24 to the transfer 28 can be suitably prevented and the top end 40 is directly supported by the engine side member 44, and hence vibration modes absorbed by the insulator 48 of the rear engine mount 18 are made simple and specific. Therefore, the vibration characteristics of the rear engine mount 18 can be tuned easily fully.

摘要： PROBLEM TO BE SOLVED: To reduce generation amount of NOx by providing a gas feel injection valve, setting an injection period according to the operating state of an engine for a gas fuel injection valve and performing a control to intermittently inject gas feel from a gas fuel injection valve during the injection period. SOLUTION: A period to inject gas fuel from a gas fuel injection valve 10 is calculated within an electronic control unit 20. When an injection request flag is set, a signal to discharge a piezoelectric element of the gas fuel injection valve 10 and a signal to charge the element are alternately generated in a fixed time interval while the injection request flag is set. As a result, gas fuel is intermittently injected from the gas fuel injection valve 10. This period to inject gas fuel is preliminarily stored in the form of functions of working amount of an acceleration pedal 30 and engine speed within a ROM 22. Thus, when gas fuel is intermittently injected, generation amount of soot and NOx can be remarkably reduced.

摘要： PURPOSE:To suppress generation of smokes and NOx to substantially zero by injecting the fuel into the combustion chamber at the specified timings, specifying the mean particle size of the fuel injected, allowing the fuel in particle state to boil and evaporate after the compressive upper dead center approximately, and thereby performing the fuel ignition and combustion. CONSTITUTION:An internal combustion engine is structured so that the fuel spreading in the form of thin film is injected from a fuel injection valve 10 furnished in the combustion chamber 5 into the whole space of the combustion chamber 5, wherein the fuel injection should take place under the compression stroke 60deg. before the compressive upper dead center approximately or under the suction stroke, and thereby the injected fuel is dispersed in the whole space of the combustion chamber 5. The particle temp. of mean particle size at fuel injection is made greater than the particle size to attain the boiling point of the main fuel component determined by the pressure at the compressive upper dead center approximately or after the compressive upper dead center so that evaporation of the fuel due to boiling from the particle state is hindered until the compressive upper dead center is attained approximately after the injection. After the compressive upper dead center, the fuel in the particle from is boiled and evaporated so that the fuel ignition and combustion are conducted.

摘要： PURPOSE:To make it possible to precisely feed a plurality of fuels with a simple structure, by coupling a second fuel passage with the intermediate section of a first fuel passage through a communication passage. CONSTITUTION:The body 70 of a fuel injection valve 14 is formed therein with a first fuel passage 74 for supplying first fuel into a fuel injection port 68 and a second fuel passage 78 for introducing second fuel. Further, the second fuel passage 78 is coupled to the coupling part 102 of the first fuel passage 74 through a communication passage 100. The second fuel is fed at a pressure which is lower than the valve opening pressure and is driven into the fuel passage 74 through the communication passage 100. At this time, a seat part 104 is closed so that the second fuel may not flow downward, and therefore flows into the upper section above the coupling part 102 while it pushed back the first fuel. Accordingly, the first fuel is pooled in the fuel passage 74 stratiformly between the fuel injection port 68 and the coupling part 102, then the second fuel which has been driven into, is pooled, and further the first fuel is pooled thereover. Thereby it is possible to inject a plurality of fuel, stratiformly.

摘要： PURPOSE:To prevent variance in fuel feed rates from cylinder to cylinder in a Diesel engine, etc. by distributing auxiliary fuel from a valve mechanism to each of dual fuel injection valves via each of branch passages having respective throttle means. CONSTITUTION:During a period when a valve of a valve mechanism 42 of an auxiliary fuel supply device 4 is open, auxiliary fuel is supplied to each of auxiliary fuel ports 13 of each of dual fuel injection valves 1 and injected prior to a main fuel coming from a distribution type main fuel injection pump 2. Since the flow rate of this auxiliary fuel is determined by two factors of pressure differentials between an outflow passage 88 and spaces 19 and line resistances between the passage and the spaces, a throttle 102 having a relatively great passing resistance is arranged in the middle of each of passages 101 to minimize variance in the line resistances. Thus, the variance in the fuel feed rate is prevented and reliability in uniform distribution is improved with a simple constitution.
