Since the EGR system recirculates a portion of exhaust gases, over time the valve can become clogged with carbon deposits, which will prevent it from operating properly. Clogged EGR valves can sometimes be cleaned, but replacement is necessary if the valve is faulty.
PCV valve on Ford Taunus V4 engine (feeding from left side valve cover into the inlet manifold) A crankcase ventilation system (CVS) removes unwanted gases from the crankcase of an internal combustion engine. The system usually consists of a tube, a one-way valve and a vacuum source (such as the inlet manifold).
Each MCA-Jet valve and valve seat are a self-contained cylinder-shaped unit that screws into the cylinder head for easy replacement. Aftermarket MCA-Jet valves are available. With the advent of 4-valve-per-cylinder engines, manufacturers typically design the camshaft(s) to open one intake valve slightly before the other to create a swirling effect.
It is a family of 3-cylinder and 4-cylinder diesel engines featuring modular diesel engine system (MDB (Modularer Diesel Motor Baukasten)), [3] [4] [5] with dual-loop EGR system, with high pressure EGR and a cooled low-pressure EGR loops; variable valve train (VVT) with a camshaft adjuster, Bosch CRS 2-20 2000 bar common rail injection system ...
The 6.4 L also has a DPF and dual EGR coolers which are capable of reducing exhaust gas temps by up to 1,000 degrees before they reach the EGR valve and mix with the intake charge. The DPF traps soot and particulates from the exhaust and virtually eliminates the black smoke that most diesel engines expel upon acceleration. The engine computer ...
While this early effort to match the vacuum-controlled EGR volume more accurately to the engine's load made sense in a conventional engine, it had the effect of causing pinging (detonation) problems in the V8-6-4 engine, because four cylinders operating under higher load needed more EGR, while they were actually producing less exhaust flow and ...
