P1 explain and compare the operation of two different diesel fuel injection systems used on modern diesel engines P2 describe two different types of diesel fuel supply methods P3 identify and explain the function and operation of the air and diesel fuel supply components of a given diesel fuel injection system P4 describe the function and. 0 Power Stroke. 3 Powertroke, 6. Setting Valves and Injectors on a Cat 3116 Diesel Engine. The engine runs fine otherwise, no missing or loss of power. At Thoroughbred Diesel, you can buy stock diesel replacement parts such as injectors, fuel pumps, ball joints, track bars, turbos, and more for your diesel truck. Before making a repair attempt, the following tests should be performed: Verify that the noise occurs with a hot engine, not cold.

Most common failure mode is known as ‘cold knock’ which essentially sounds like there is a major fault with a bottom end bearing – only whilst cold. Although common rails are an improvement from prior types of fuel systems, they’re not without their issues. This leak will result in a decrease in fuel efficiency, and in some cases performance and acceleration. then its a very unstable cycle causing a lot of noise and sometimes it sounds like a metallic metal on metal sound. An ultrasonic cleaner, or a set of picks and lots of patience. Ford Lehman Marine Diesel engine stuff. [Archive] 2008 6. As a result, any part of the return line system blew off and a really bad feul knock occured before the lines blew off. diesel engine parts because it is not a good lubricant. Severe diesel knocking can,and will, damage an engine: it is caused by a too advanced injection of the diesel; meaning that the diesel is (due to a defect) injected too many degrees before TDC(top dead center),while the piston is still going up; i. How much Sea Foam should I add to my crankcase oil? Add 1 to 1. In many cases, white smoke emanating from the tailpipe (often at idle once the engine reached operating temperature) typically means a worn out injector. Engine misfires and decrease in power, acceleration, and fuel efficiency. Hi all, Recently got a glow plug + engine light fault on my 2004 diesel x type with 180. The piezo injectors can divide the injection cycle into as many as five separate injection events, each specially timed to maximize combustion efficiency. The same thing has happened to me and replacing the injector always fixed the problem. Faulty injector/s Probably the biggest result of injector failure is due to the injectors having excessive return flow or back leakage. In addition, diesel engines tend to create loud noise, also known as diesel clatter, diesel knock, and diesel nailing. As you know, diesel injectors are expensive and this can be very costly. A diesel engine is difficult to start in cold weather due to its lack of an electronic ignition system. 2 diesel engine YD22DDTi/2. Here we have provided a download and keep guide on these warning signs of injector failure. The fuel injector, though small, is a very solidly constructed fuel system component part. Crack the injector lines loose one at a time and see if you can figure out which hole it is. Today's low sulfur diesel fuels are more likely to leave varnish and gum deposits on injectors, and also provide less lubrication so you might recommend an additive to keep things flowing smoothly. Also i heard of a glow plug upgrade thats done under warranty but its a big job. 1999 - 2003 7. Hi, I see similar threads but not exactly as per my problem. Many of these problems, however, stem from things unrelated to the design of a common rail system, which common rail owners should be aware if they want to minimize expensive repairs. Diesel Extreme’s powerful injector cleaner will also clean all components of your fuel system, including upper cylinders, fuel tank, fuel pumps and lines. Don’t settle for less! The 6. Posted: Mon Jun 14, 2010 6:59 am Post subject: Engine knock on a 3000 Diesel My 3000 is developing an engine knock when it gets hot. Update, the owner told me that the diesel repair shop that looked at it last week said they manually disconnected the wiring harness to each injector and it didn't change the sound. The fact-checkers, whose work is more and more important for those who prefer facts over lies, police the line between fact and falsehood on a day-to-day basis, and do a great job. Today, my small contribution is to pass along a very good overview that reflects on one of Trump’s favorite overarching falsehoods. Namely: Trump describes an America in which everything was going down the tubes under  Obama, which is why we needed Trump to make America great again. And he claims that this project has come to fruition, with America setting records for prosperity under his leadership and guidance. “Obama bad; Trump good” is pretty much his analysis in all areas and measurement of U.S. activity, especially economically. Even if this were true, it would reflect poorly on Trump’s character, but it has the added problem of being false, a big lie made up of many small ones. Personally, I don’t assume that all economic measurements directly reflect the leadership of whoever occupies the Oval Office, nor am I smart enough to figure out what causes what in the economy. But the idea that presidents get the credit or the blame for the economy during their tenure is a political fact of life. Trump, in his adorable, immodest mendacity, not only claims credit for everything good that happens in the economy, but tells people, literally and specifically, that they have to vote for him even if they hate him, because without his guidance, their 401(k) accounts “will go down the tubes.” That would be offensive even if it were true, but it is utterly false. The stock market has been on a 10-year run of steady gains that began in 2009, the year Barack Obama was inaugurated. But why would anyone care about that? It’s only an unarguable, stubborn fact. Still, speaking of facts, there are so many measurements and indicators of how the economy is doing, that those not committed to an honest investigation can find evidence for whatever they want to believe. Trump and his most committed followers want to believe that everything was terrible under Barack Obama and great under Trump. That’s baloney. Anyone who believes that believes something false. And a series of charts and graphs published Monday in the Washington Post and explained by Economics Correspondent Heather Long provides the data that tells the tale. The details are complicated. Click through to the link above and you’ll learn much. But the overview is pretty simply this: The U.S. economy had a major meltdown in the last year of the George W. Bush presidency. Again, I’m not smart enough to know how much of this was Bush’s “fault.” But he had been in office for six years when the trouble started. So, if it’s ever reasonable to hold a president accountable for the performance of the economy, the timeline is bad for Bush. GDP growth went negative. Job growth fell sharply and then went negative. Median household income shrank. The Dow Jones Industrial Average dropped by more than 5,000 points! U.S. manufacturing output plunged, as did average home values, as did average hourly wages, as did measures of consumer confidence and most other indicators of economic health. (Backup for that is contained in the Post piece I linked to above.) Barack Obama inherited that mess of falling numbers, which continued during his first year in office, 2009, as he put in place policies designed to turn it around. By 2010, Obama’s second year, pretty much all of the negative numbers had turned positive. By the time Obama was up for reelection in 2012, all of them were headed in the right direction, which is certainly among the reasons voters gave him a second term by a solid (not landslide) margin. Basically, all of those good numbers continued throughout the second Obama term. The U.S. GDP, probably the single best measure of how the economy is doing, grew by 2.9 percent in 2015, which was Obama’s seventh year in office and was the best GDP growth number since before the crash of the late Bush years. GDP growth slowed to 1.6 percent in 2016, which may have been among the indicators that supported Trump’s campaign-year argument that everything was going to hell and only he could fix it. During the first year of Trump, GDP growth grew to 2.4 percent, which is decent but not great and anyway, a reasonable person would acknowledge that — to the degree that economic performance is to the credit or blame of the president — the performance in the first year of a new president is a mixture of the old and new policies. In Trump’s second year, 2018, the GDP grew 2.9 percent, equaling Obama’s best year, and so far in 2019, the growth rate has fallen to 2.1 percent, a mediocre number and a decline for which Trump presumably accepts no responsibility and blames either Nancy Pelosi, Ilhan Omar or, if he can swing it, Barack Obama. I suppose it’s natural for a president to want to take credit for everything good that happens on his (or someday her) watch, but not the blame for anything bad. Trump is more blatant about this than most. If we judge by his bad but remarkably steady approval ratings (today, according to the average maintained by 538.com, it’s 41.9 approval/ 53.7 disapproval) the pretty-good economy is not winning him new supporters, nor is his constant exaggeration of his accomplishments costing him many old ones). I already offered it above, but the full Washington Post workup of these numbers, and commentary/explanation by economics correspondent Heather Long, are here. On a related matter, if you care about what used to be called fiscal conservatism, which is the belief that federal debt and deficit matter, here’s a New York Times analysis, based on Congressional Budget Office data, suggesting that the annual budget deficit (that’s the amount the government borrows every year reflecting that amount by which federal spending exceeds revenues) which fell steadily during the Obama years, from a peak of $1.4 trillion at the beginning of the Obama administration, to $585 billion in 2016 (Obama’s last year in office), will be back up to $960 billion this fiscal year, and back over $1 trillion in 2020. (Here’s the New York Times piece detailing those numbers.) Trump is currently floating various tax cuts for the rich and the poor that will presumably worsen those projections, if passed. As the Times piece reported:
