High power inverter will be about 90% efficient. If the 400 Hz unit is 3 phase, a delta-wye bridge rectifier would produce DC with very little ripple. And you wouldn't need any boost section on the inverter either, increasing the efficiency. This is becoming more common in long distance power...

I have worked on vehicles that have been abused by running vegetable oils. I don't claim to be an expert but I have researched the reasons it is a BAD idea. The steels used in the IP and injectors is NOT a corrosion resistant alloy, it is chosen for strength and wear properties. Vegetable...

Scam. aua

Please stop the madness. European diesel isn't any "cleaner" than USA ASTM specification. All diesel is DISTILLED, not only "filtered" from crude. There is no "racket" with the price, it is much more expensive since the mandate for ULSD. And the M1008, 1010, 1028 and 1031 are one ton, so...

Please don't. Vegetable oils are reactive and turn to varnish/sludge in the high pressure/high temperature injection system. Injection pumps are high pressure hydraulics built like Swiss watches. They demand clean, non-reactive diesel. While it may run, it won't for long. :deadhorse:

Appendix F of the -20 TM. Or Appendix E of the -34 TM. That would be TM 9-2320-289-20 or -34.

First, check the wiring. Print out the F-10 in the appendix of the -20 TM, study it and compare with yours. Then get TB 43-0001-39-8 and check to see if this TB has been applied. You should have 3 diodes hanging by wires in the vicinity of the Duvac/Twinput. They are covered with tape and...

It is AC and the tachometer calculates crank speed by the frequency. You have to take into account the pulley (sheave) ratio. Alternators turn 1.5 to 3 times the crank speed. Or more on slower diesels. Usually want to keep the alternator under 10,000 RPM as frequencies above 200 Hz (12,000...

Resurrecting this thread for progress. We had thought replacing the burned-out diode between the IGN term on the upper alt to the FLD term on the Twinput solved the charging issues. But over the weekend, prolonged idling caused the front battery to cook, H2S spewing and a hot battery. So...

After glow is the turning on of the glowplugs after the engine is running to warm the precombustion chamber. Like stated, this reduces emissions by decreasing ignition delay. But it does increase idle noise. It also increases the load on the engine, since the injection pump is also a...

Are the singles radial? That would make all the difference, being much less stable in lateral loading. This would reduce the lateral forces which cause the towed wheels to turn. This opposes the caster angle on the towed vehicle which tends to restore the steering angle to zero (straight...

The oil is probably the least of your worries. Just check the level, if it is very high, chances are there is a fuel leak in the IP. The Army sampled and analyzed the oil on regular basis, changing only when Army Oil Analysis Program required. As long as the engine has proper pressure, it...

The Diesel cycle relies on autoignition. At time of injection, the aerosol mist ignites almost instantly. If the delay is more than the total duration of the injection (low power), you get that diesel "knock". The delay is based on many factors, mostly due to the characteristic called cetane...

Hypercycle is direct injection with a spherical chamber. Intake rotation is vertical where in the modern direct injected diesel has the toroidal combustion chamber. The difference? Hypercycle is designed to sweep pooling liquid fuel into the fire more effectively.

The "multi" in multi-fuel meant use of Mogas in addition to diesel or jet fuels. Most true diesels just will not run on gasoline. And the 6.2 GM was never designed with that capacity as the injection pump is lubed with the fuel, gasoline would cause rapid wear. When the Hypercycle was being...

Some heavy, thick snow there. With a slippery mud base too. How did you snap the axle? Turning under power? Love to see the photos of that.

Caster and camber are set by king pin alignment. There isn't any adjustment that can be made. Only toe. You could have king pin wear. Major work to repair

And warn people to take cover, especially on the starboard (right) side, to take cover. Multifuels tend to spatter.2cents

You have to understand how the transmission is "programmed" to shift using the manifold vacuum of a gasoline engine. And vacuum is inversely proportional to power in normally aspirated gasoline engines. Most gasoline engines pull 17-19" Hg at idle or when coasting, sometimes more. When the...

I am talking about THIS direct injected "diesel" engine. It it DI, most DI engines of this size will have a 17:1 to 18:1 compression ratio. Not 22:1. The ONLY reason it is that high is for use of gasoline fuels (although aviation gasoline with its higher octane index cannot be used)...
