Re: Air flow increase with electric fans on rear of radiator

'I will be interested in the'pressure balance' with and without the fans running at road speed   say 55 MPH.My scientific fluid-flow knowledge leads me to suspect the engine compartment under the bed is a substantial NEGATIVE pressure to that just aft of the Charge cooler. If my assumption is valid,...

Re: 3126 Injector Failure

'Delayed fuel injection will reduce power output due to less time force is applied to piston turning crankshaft. However, compressible fuel (dissolved air or actual bubbles in fuel) will also dramatically reduce VOLUME OF FUEL injected per cycle. The delayed start of injection is a contributor, but ...

Re: 3126 Injector Failure

'A little CLARITY about how fuel flow effects a diesel engine.   A diesel ALWAYS run in a 'fuel limited-fuel lean' combustion mode.  Power output is ALWAYS limited by fuel input--whether from reduced throttle position  or fuel filter restriction--- the actual impact on engine combustion/power output...

Re: 3126 Injector Failure

'Attachments :Diesel Fuel Injectors are subject to rapid wear if water (or very fine particles) are present in the fuel. The nozzles have a number of very fine openings through which the fuel must flow correctly. Water and any particles will erode (wear) and plug those very fine openings and cause t...

Re: 7.5 Quiet Diesel Overheat cooling air drawn over muffler

'thanks.. Not ;exhaust wrap', but a sheet of aluminum flashing wrapped around, with fiberglass pads to keep it from touching and making noise. Air flowing through the gap will lower the skin temp of the aluminum by some 300 degrees, reducing the radiant heat flux by 80%.  The 'Alabama Heat Shield ' ...

Re: 7.5 Quiet Diesel Overheat cooling air drawn over muffler

'If will be a simple fix---if you want to do it. Simply make and install a simple 'wrap' around the muffler and exhaust pipe to act as a radiant heat barrier.   Buy a length of 24" wide aluminum flashing , cut lengths long enough to wrap around the muffler with an air gap of at least an inch. C...

Re: Average MPG

'The single biggest impact on MPG is SPEED. Of course tires must be properly inflated for the load on EACH wheel. Knowing the actual weight on each wheel is IMPORTANT so proper inflation can be used. AVERAGE weight is NOT SUFFICIENT Driving 55 MPH instead of 70 MPH will increase MPG 40% or more.    ...
