The engine technical category is dedicated to technical diesel articles like what diesel fuel is the best and how turbochargers increase diesel performance. Scroll down for more technical articles for the Ford PowerStroke, Ram Cummins, and more diesel engines.
For over a decade now, the Ford 6.7 Powerstroke and Dodge’s 6.7 Cummins have been the top of the line for turbo-diesel power plants. Yet, besides their displacement, they actually share very little in common. For starters, the Powerstroke is a V8 while the Cummins is an inline-six. However, they are two of the most…
If you were looking for turbo-diesel power in the 1990s and early-2000s, you had two main choices: Ford’s 7.3 Powerstroke V8 or Dodge’s 5.9 Cummins I6. These were some of the first modern diesels to have direct injection and turbochargers as standard, opening up entire new worlds of performance opportunities. Though now long out of…
The procedures given in this section for valve lash adjustment are to be performed at the initial 38,000 km [24,000 mi] adjustment. Subsequent adjustments are to be performed at 77,000 km [48,000 mi] intervals. With a 15 mm wrench, remove the valve cover. 1/2 Inch Drive, 3824591 Engine Barring Gear Locate Top Dead Center (TDC)…
Controlled venting is provided at the injection pump through the fuel drain manifold. Small amounts of air introduced by changing the filters or injection pump supply line will be vented automatically, if the fuel filter is changed in accordance with the instructions. No manual bleeding of fuel lines is required. NOTE: Manual bleeding is required if:…
Cause Correction Low Fuel Level in Tank Fill fuel supply tank. OK Idle Speed Too Low Check / adjust low idle screw setting. OK Air in the Fuel System Bleed fuel system and check for suction leaks. OK Fuel Supply Restricted Clean or replace pre-filters and screens, check for fuel line restrictions. OK One or more…
Cause Correction Incorrect Starting Procedure Refer to “The Starting Procedure Matrix“. OK No Fuel in Tank Add fuel. OK Electric or Manual Fuel Shutdown Not Open Check for loose wires and verify that the solenoid is functioning. Check to be sure the manual shut-off lever is in the “Run” position. OK If the condition occurs…
Often times we get questions about why someone’s well running diesel truck isn’t “rollin’ coal” or making black smoke. The simple answer is, the fact that you are not seeing any black smoke is a good thing. A properly running diesel engine should not have any smoke at all. Black smoke is an indication of restricted…
Warm it up Diesel engines clatter when they are cold. This is because diesel engines rely on the heat generated by compressing air in the cylinders in the engine for the diesel to ignite, with a cold block and cold air, combustion is not very efficient. When you start a diesel engine for the first…
Why Do Diesel Fuel Injectors Fail? There are two major causes of diesel fuel injector failure associated with the properties of the fuel itself: excess wear and deposits. 1) Common Reasons Diesel Injectors Fail: Excessive Wear One mode of injector failure is excess wear. Prior to 2006, diesel fuels in the United States contained relatively…
Diesel fuel is graded and designated by the American Society for Testing and Materials (ASTM), while its specific gravity and high and low heat values are listed by the American Petroleum Institute (API). Each individual oil refiner and supplier attempts to produce diesel fuels that comply as closely as possible with ASTM and API specifications….
A turbocharger is an exhaust-driven supercharger (fan or blower) that forces air into the engine under pressure. Turbochargers are frequently used on diesel engines to increase power output. Turbochargers are well suited to operation in diesel engines because the diesel engine is immune to detonation as the fuel is not injected until the moment of combustion. By harnessing…
