To do this, you'll probably need to work with a camshaft guru who can do all of the mathematics to get you the cam that will do what you want. The injector it's self has different calibrations like high, low, medium etc, a good injector shop like the one I use will calibrate a injector for what ever I am planning for the engine fwiw a injector for a 2 stroke can have as much as 25+ variations. Quick Links: Fuel System Priming Pump and Relative... Unlike its spark-ignited engine counterpart, the diesel fuel injection system delivers fuel under extremely high injection pressures. It's important to remember that a small movement of the pump will result in a large timing change, so do not make any drastic adjustments. Detroit diesel injector timing chart for car. The DDEC also has the ability to shut an engine down in the event of an emergency that may result in severe engine damage, such as low/no oil pressure, excessive engine coolant temperature, and excessive oil temperature. No mechanical work needs to be done, except for getting to the ECM. Engine Starts But Will Not Keep Running. Fuel Injector Timing - Detroit Diesel 53 Series Service Manual. So i set the injectors to 1.
Diagram courtesy of Levy Art and Architecture. The seal between the combustion chamber and crankcase should be completely sealed after the initial break-in period. The engine could be delivering too much fuel, not enough fuel, too much air or simply not enough air. DDECII - The second generation DDEC system eliminated the EDU and instead the ECM picked up the task of actuating the injector solenoids. Last Edit: August 03, 2013, 01:37:03 PM by Brian Evans. Terms like P-Type, M-Type, or S-Type nozzle refer to standardized dimensions of nozzle parameters, as per ISO specifications. While the main purpose of the system is to deliver fuel to the cylinders of a diesel engine, it is how that fuel is delivered that makes the difference in engine performance, emissions, and noise characteristics. While there is considerable variation in terminology, a close post-injection will be referred to as a post-injection and a late post-injection as an after-injection. Diesel injection timing light. • Damaged/Clogged EGR Cooler. Multiple injection events. Added to my manuals.
460000" would need to be measured with a laser and at a set temperature - varying the temperature a few degrees would change the measurement. 2 seconds with 27 queries. 460, should they be at that or is something better or not and why? Thanks again to everybody who chimed in!
470 moved the power band slightly lower and reduced soot a bit. Valvetrain: Overhead camshaft, roller follower rocker arms, 4 valves per cylinder (2 intake, 2 exhaust valves per cylinder). If 5 years from now an injector goes bad how does one know how to set up a replacement? • Wrong Blend of Diesel Fuel For Temperature. Detroit diesel 53 series injector. Some of the more common of these include [922] [2075]: Nozzle refers to the part of the nozzle body/needle assembly which interfaces with the combustion chamber of the engine. Luvrbus also what different setups are you asking for and why? From there, a mechanic can plug in a Flash tool to reprogram the computer.
I blew out the fuel supply line and hooked up a little transfer pump to push fuel through both the strainer, fuel pump, filter, and i had fuel coming out the return. More than that, low power forces the driver to drop gears increasing the number of injections over the same distance and wasting even more fuel. Engine Operating Fuel Pressure is Low. This timing is usually balanced to get as much power as possible, while still remaining in legal limits for emissions. In common rail systems, it contains the main functional parts: the servo-hydraulic circuit and the hydraulic actuator (electromagnetic or piezoelectric). The presence of blue smoke is an indication of burning oil. Consequently, the Fuel Preporator equipped engine is the more efficient engine! Fuel Injector Timing - Detroit Diesel 53 Series Service Manual [Page 66. You say a smaller number fires sooner so I guess that is what my 6V92TA is doing. Air entrainment reduced this to 23. BNO Email Login Page. 2001 - 2011, various on/off highway. Each change of the DDEC system represented an improvement in emissions and diagnostic capabilities, amongst other features.
Print document (84 pages). 60 Series Diesel Fuel. This is a preview of the paper, limited to some initial content. If a stop lever is provided, secure it in. If you get more fuel into the engine than can be burned with the amount of air you get black smoke from unburned fuel.
The following 6 charts and the brief summary are from the Analysis of the Olsen Ecologic ISO 8178 Test by Vineyard Technology. 460000 has to do with precision. OEM is the abbreviation for Original Equipment Manufacturer. This means that they aren't originally set to produce the most power that the engine is capable of. Cold temperatures can cause older more worn rings to unseat just a bit due to deposits found around the rings or cylinders. Last Edit: August 03, 2013, 10:24:06 AM by luvrbus. And even that would still require a set standard of injector timing from the rocker. Six cylinder engine. When diagnosing the problem the first place to look at is the mixture of air and fuel flow into the cylinders.
DDFP Series Fuel System - Section 3. The original engine manufacturers set the timing to balance power and emissions, so that the engines they produce get as much power as possible while staying within legal emissions regulations. This system paved the way for superior injection control, thus maximizing fuel economy and performance in addition to granting the vehicle various diagnostic features and reduced emissions. DDECIII & DDECIV - Third and fourth generation DDEC systems expanded diagnostic capabilities and introduced the Diagnostic Data Reader (DDR) function. The main injection event provides the bulk of the fuel for the engine cycle. The retarded injection results in unburned hydrocarbons and deposits, The two out of three injections that are timely, result in higher temperatures and increased NOx gasses. 60 Series engine family. Maybe you should adjust timing.
An improved engine block was introduced after November 30th, 1994; engines with serial number 6R210293 and later feature this engine block design. Furthermore, the Detroit 60 Series features a single overhead camshaft to operate its intake valves, exhaust valves, and fuel injector plungers. Caterpillar®, PEHP7046: "Damage can be caused by anything in your fuel system that should not be there, including particles, heat, water and air bubbles. In fact, as the filter becomes more restrictive to the fuel flow as it plugs with use, these conditions become much worse! Newer electronic diesel engines with common rail injectorssimultaneously match the speed of the turbo with the metered flow of diesel fuel into the cylinder. Configuration: Inline 6 cylinder.
• Fuel Mixed with Oil. As pointed out by the University of Illinois College of Engineering study, one out of every three injections is retarded. MBE 4000 DDEC VI Spn 651 - Injector #1 Not Operating Normally. Injected fuel quantity is the amount of fuel delivered to an engine cylinder per power stroke. Valve rocker cover, using a new gasket. 460 was a efficient power setting, and 1. Causes of Diesel Engine Smoke - By Color. 'Your website is working well for me - This month I have shipped engines to Canada, South America and several in the USA. Engine Speed Surges at Low or High Idle. 425 - 515 hp @ 1, 800 RPM. Lack of data for the baseline and wide variability in recorded results under otherwise similar conditions precludes any definitive analysis of PM. This is where it got not cranking or running the transfer pump the fuel filter level would drop, and quick enough to see it drop but the only thing lower than it is the fuel pump itself, for fuel to run back past the strainer it has to go uphill. The ISO 8178 is actually a collection of many steady-state test cycles (type C1, C2, D1, etc. )
It is often expressed in mm3/stroke or mg/stroke. I told Don that I was timed at 1. An engine equipped with the Fuel Preporator, having a timely injection and complete burn of the fuel, develops more power from the same volume of fuel than it would when equipped with the vacuum feed filter system. If no further engine tune-up is required, install the. Common Causes of White Smoke: • Damaged Injectors. 460 for standard timing on the cam gear. Electrical signals are converted into mechanical forces using some type of actuator. I had Don Fairchild time my engine for optimum operation at 1800rpm. For older, mechanical engines, there are still several parts that you can manipulate in some way to change the timing. Each type and specification of injector will have different internal gubbins that control fuel volume, where the fuel ports are, the profile of the plunger, the needle valve spring setting, the size of the spray tip. Here are some of the variations I found in my Detroit manual. 01-18-2015 14:58:21.
