That happens more likely due to the high 40-42 psi stock boost pressure. In first, factory pistons are prone to crake. But 6.4 Power Stroke is perhaps the best you could achieve from the previous 6.0L version in terms of reliability. The 6.4L, based on the same basic architecture as the 6.0L, retained some of its bad and good design features as well. In 2011, Ford began offering the newest 6.7-liter V8 diesel engine - the 6.7L Power Stroke, designed and manufactured in-house by Ford.Ħ.4 Power Stroke Engine Problems and Reliability The 6.4L Power Stroke became the last diesel engine supplied to Ford by International Navistar. During that active regeneration process, additional fuel is injected on the engine's exhaust stroke to effectively burn out the trapped particles in the DPF. The manufacturer provided the special regeneration process for the DPF to make it as a self-cleaning device. To reduce particulate matter production, the engine exhaust system received a diesel particulate filter (DPF). Almost 25 percent of intake air contains exhaust gases now, lowering NOx emissions. The 6.4L was equipped with an additional exhaust gas recirculation (EGR), two EGR coolers, and EGR valve with a stronger DC motor. All 6.4L diesel engines come with an air-to-air intercooler. This twin sequential turbocharger system gives such benefits as reduced turbo lag and improved overall performance characteristic. It combined a 65 mm fixed geometry low-pressure unit with a 52 mm variable geometry high-pressure turbocharger. The engine has the compound turbo setup - The compact package of turbochargers manufactured by BorgWarner. These injectors are capable of pulling off five events during the course of each cylinder's power stroke and deliver much more precise fueling than the HEUI injectors could. The engine also was equipped a first in the segment with the piezoelectric injectors. The K16 fuel pump is capable of producing 24,650 psi. The fuel is provided by the Siemens VDO K16 high-pressure fuel pump which is located at the rear of the lift valley. The 6.4L Power Stroke engine moved from the HEUI to direct high-pressure common rail fuel injection system. Each rocker arm opens and closes two valves at once together. The 6.7 Power Stroke has a conventional single cam in block and OHV pushrod valvetrain. Like the 6.0L version, cylinder heads have just four head bolts per cylinder, but 6.7L got 16 mm head bolts instead of 14 mm. On top, there are cast iron cylinder heads with four valves per cylinder.
The 6.4L uses powdered-metal connecting rods which are much beefier and stronger than what you'll find in the 6.0L, and capable of handling more than 900 rwhp. This bed plate is securely cinched down to the engine block via four bolts per main. All of these problems can be solved by removing DPF and remapping ECU using our DPF Off files.Like the 6.0L Power Stroke, the 6.4L version has a cast-iron cylinder block and a cast iron bed plate that eliminated traditional main bearing caps.
If we stop this process or these prerequisites are not met, the DPF filter will not regenerate.īelow we present a list of common errors related to DPF.
If they do not work effectively, it can potentially accelerate DPF blocking. Faulty / damaged swirl flaps – Like the EGR valve, the swivel flaps are fitted to help control the emissions in the vehicle.In some cars, if the EGR system is not working effectively or is blocked, the amount of exhaust gas flowing through the DPF will be increased potentially increasing the blocking of the DPF. Defective / Damaged EGR Valve – The EGR valve is designed to recirculate the exhaust gases back to the engine before passing through the DPF.If one or more of these sensors fail, the regeneration process may stop running. These sensors are adapted to monitor the initial and final temperatures as well as the back pressure of the filter. Damaged / defective sensors – DPF has several sensors that are installed before and after the filter.In order for the DPF regeneration process to work efficiently and burn coal deposits, the engine must often reach the correct operating temperature. Short trips – vehicles with a large “urban driving” are more prone to blocking because the DPF filter does not reach sufficient temperature.Things that can lead to blocking the DPF filter: It is worth taking further diagnostics to find the reason for this situation. A substantially blocked DPF filter is usually caused by another major problem.
