Yanmar injector opening pressure

yanmar injector opening pressure 00. Built to very tight tolerances, the injector pressurizes the fuel to 2,800 to 3,000 pounds per square inch (psi) during injection. Injection is sharper and post injection dripping is restrained, which eliminates contamination from unburned fuel. Temp. High pressure injectors fitted to direct injection spark ignition and common rail compression ignition engines use hydraulic imbalance to open the injector, so this test is not suitable for these applications. 6 kgf/cm 0. 12 - 0.

A fuel pressure regulator is used to maintain steady fuel supply, even during dramatic changes in fuel demand. 2 mm diameter • Drop size 0. If the pressure fails to rise to the required pressure, the fuel pump is at fault. Max. It should also hold the pressure for at least 5 minutes without falling. com. Thanks for watch The adjustments are made by inserting different size shims into the injector that increase/decrease the "pop" pressure of that injector. 9 6510-BOS-2K Yanmar 4LH-DTE, Volvo 30/31/40/41, Perkins 4. Get more in-depth insight on Yanmar Engines and find specific machine specifications on LECTURA Specs. For compression ignition (CI) engines, two of the fuel injection parameters affecting the engine’s performance and emissions formation, are fuel injection timing (FIT) and injector opening pressure (IOP). The pressure to deliver fuel from the high pressure pump to the rail/injectors at cranking is around 200 bars, at idle the pressure should be around 300 bars. . Throttle linkage is working fine. 9 Adjusting No. Spray Pattern Test 1. For instance, the 24 MPa shown on the gauge equals 240 bar, which is the same as 3480 psi. 1 mm) results in a change in the injection opening pressure of about 290 psi (2 MPa, 20 kgf/cm2) Spray from each nozzle hole is uniform. 0 The effects of injection timing (IT), injector opening pressure (IOP) and compression ratio (CR) on brake thermal efficiency (BTE) of a single-cylinder direct injection (DI) diesel engine was reported. The valve is located at the front of the pump and is removes using a 10mm box end wrench or equivalent. 7. After the injector opens, check to make sure the pressure does not fall off too quickly. 06 MPa (8. The 2GM injector opening pressure is 170 kg/cm2 .

I'm hoping one of them is right and only one is wrong, not both wrong. 204): So when the spool opens, high-pressure oil enters the injector. YANMAR judges if the part can be used continuously after repairing. The fuel injection system lies at the very heart of the diesel engine. 04, Issue 02 (February. The fuel is atomized and distributed into the combustion chamber or as in the case on your engine, the per-combustion chamber where it is ignited. ORIGINAL Yanmar Injector Nozzle Protector 119802-11870. The fuel rail pressure / injector operating pressure is generally greater on this system which allows for finer fuel spray. Nozzles - Yanmar - Dieselservice Stokking BV - Gespecialiseerd in de dieselmotor en zijn toepassingen TDI injectors pressure 170 bar View: 34591 Yanmar 129503 The opening pressure (OP) in a healthy individual is determined by the rates of production and drainage of CSF. Does anybody know the correct pressure to over to the high pressure flow path to each cylinder with the distribution shaft, opening delivery valve, high pressure pipe, fuel injection valve, and engine cylinders in this order. INJECTOR HOLD-DOWN FLANGE. Typical operating voltages and current on most systems may be in the range of 100 – 400V and minus 20 to +20 Amps. Fuel Injection Nozzle 3-38 8. If you have any queries you can comment. This engine is also equipped with a cooled EGR and a DPF, which allow the machine to meet EN-Standards. When the injector line has even the smallest amount of air in it, the air will compress and the required pressure can Both nozzles were tested at injection pressures of 10, 20 50 and 80 MPa. 206. Brief Summary. The surface gas injection pressure is 1200 psia. The injector test pressure values are the flow test pressures for both the stock fuel injectors and current fuel injectors. Notice the bump at about -1 ms which is caused by the change in inductance as the pintel (plunger) moved (opens). Nozzle injectors of 3, 4 and 5 holes, each of 0. The best way to diagnose this is to look at the fuel supply in 3 areas. Free download. If playback doesn't begin shortly, try restarting your device. See detailed specifications and technical data for Engines. A needle valve in the pump releases the injection pressure, hence only about 1/3 of a turn of a fine threaded bolt is required from full throttle to stop. 1 shows a typical electromagnetic common rail injector. Genuine Yanmar Part Oil Pressure Sender Alarm #124060-39452. It is used in a wide range of sailboats and motorboats. . To keep the fuel under pressure at the entrance point to the injector pump and to keep the fuel from just draining down the return line away from the tee point there is a check valve downstream of the tee. Turned off engine and tried to pull out injector. injection valve is minimized. The youtube cleaning method isn't scientific but makes sense, opening and closing can be verified, and the spray pattern can be verified. This, in turn, pushes the intensifier piston and plunger downward inside the injector body. 2. Opening Pressure: Application: 093500-1011: 14412-53001 sfiw-3854 fuel injection valve insulator $3.

Along with popular engines such as the 3TNV88 series and the 4TNV98 we carry parts for popular Yanmar marine engines such as the 3JH, 4LH, and 6LP series. {to spec} While testing 1st, they ALL opened at the exact same pressure{low} but 2 of the 3 had REAL BAD spray patterns & wouldn't chatter. High-pressure injection delivers power and fuel consumption benefits over earlier lower When reinstalling the injection pump Yanmar specifies “Screw Lock Super 203M” between the shims. 3. The nozzle opening pressure might be adjusted the same way. The difference in cross-sectional area multiplies the hydraulic force acting on the fuel 7. Testing time: 5-10 minutes. To resist high–pressure fuel leaking, the opening end of the high-pressure passage from drilling must be sealed, conventionally, with a steel plug via a vacuum brazing operation. 2 psi/ft. Therefore if the injector was assembled with no first stage spring, and a modified tube so that it had to press on the main spring right from the start then the injector would effectively become a single stage injector and one could test the opening pressure with standard equipment. when you install the timing belt. 2. but if the pressure is 100-200 psi low, replace the nozzle. Figure 9 shows that by increasing the injection pressure from 275 to 1000 bar, soot decreases about 58%. idle adjuster 55. It was manufactured between 1981 and 1989 in Yanmar's factory in Japan. Yanmar Fuel Injector Nozzle Assembly. b. A fuel injection pump comprising: a barrel formed with a main port and a sub port; a plunger; and a cold start device including an injection-advancing actuator which operates a piston for opening or closing the sub port so as to change an injection timing in correspondence to temperature, wherein the plunger is moved to connect or separate the sub port and the main port IOSR Journal of Engineering (IOSRJEN) www.
