Coal Liquefaction

US energy policies and practices affect the ability of "We the People" to continue driving our diesel vehicles.

Shortly after World War II, the United States started to import oil in order to meet its growing demand for finished petro-chemical products. The rapid escalation of plastics used in packaging, domestic utensils, automobiles and virtually every aspect of American life added to the increasing demand for petroleum. Electric generating plants that run on diesel have been easy to construct as have steam plants supplied by petroleum. This has added to the ever-increasing demand curve for petroleum. Along the way, US domestic production has increased but it could not keep up with the rapid increase in demand. As a result, petroleum imports surged to ever higher levels. Electric generating plants began to shift to burning domestic coal and natural gas, however, the demand for petroleum has not slackened. Nuclear power plants came on line with great promise. Unfortunately, public hysteria cut short the promise of a nation powered by nuclear generated electricity. Modern clean coal fired generating plants began to replace old less efficient power plants with great promise to use the vast quantities of domestic coal reserves in the US. Again, this promising technology would fall to public hysteria: smaller in number than nuclear opponents, they compensated with fanatic hyping of man-made climate change, global warming.

Heath Diesel 6.5L Diesel Oil Cooler and Hose Upgrade

Few things irritate truck-crazy people more than a messy oil leak. While it is unfortunate, many 6.5 drivers are too familiar with the poorly built stock diesel oil cooler hoses on these vehicles. They are known to leak, to fail and to ruin engines. Those of us, who have replaced these leaky rascals, find that the costly, dealer-supplied service replacement hose assemblies seldom provide more than a short term fix. These factory service units will often begin to leak oil within a few months after being replaced. Colder climates accelerate the onset of failure.
Leaking diesel oil cooler hoses are tough to live with, but a complete failure of one of these hoses is not uncommon and can result in the loss of the engine. The message here is that these tell tale leaks cannot be ignored.

AMSOIL Oil Bypass Filtration System

In summary, oil bypass filtration

  • Dramatically extends drain intervals;
  • Improves oil cooling;
  • Increases filtration capacity and life;
  • Increases fluid system capacity;
  • Efficiently removes small particles and soot;
  • Significantly extends engine life;
  • Allows equipment to run constantly on clean oil;
  • Increases engine efficiency; and,
  • Removes particles less than one micron in size.
Jon Moore of Boca Raton, Florida recently purchased a new Chevy Silverado pickup fully equipped with the Duramax and Allison for towing a fifth wheel trailer. Jon, a retired engineer from Pratt & Whitney Corporation and a longtime certified aircraft mechanic and pilot, read the Bypass article in maxxTORQUE, called me and purchased the AMSOIL Dual Remote Bypass System. This article explains the installation procedure and provides some comments on the system components, ease of installation and system quality.

Pre-Turbo Diesel Water Injection

Snake Oil And Water Don’t Mix

Terms like Nitrous, Super-Charging, Wastegate and other hormone-inspired phrases, leave the topic of Water-misting a little... dry; uninspiring to say the least. Water is not a fuel. By itself, water does not burn, dissociate, or otherwise directly increase engine power or fuel economy. But perhaps water does increase engine efficiency and fuel economy when it is used to eliminate or reduce waste heat processes that convert otherwise useful engine power into non-useful heat. Trust me, this heat, wherever it is created, has pump fuel as its origin energy source. That heat is fuel wasted that might otherwise go to propulsion.
The turbo is a major source of this heat. Whatever we can do to reduce heat manufacture during turbo compression will result in better fuel economy and lower exhaust gas temperatures (EGT). No snake oil claims here, just simple thermodynamic facts of life.
In this article, we will look at the facts behind the merits of pre-turbo diesel water injection (PTWI) as a pre-emptive cooling mechanism: a means to tame that waste heat mechanism and direct that energy to the wheels.

Duramax Power Mods and Your GM Warranty

As I started to gather material for this article about the affects of having a Duramax Power Chip or Duramax Power Programmer on your GM warranty, I was dealing with my first casualty arising from GM’s new approach to applying – and, as in my case, denying – its warranty policy. I was not happy about it. The incident involved a good customer, a failed engine and a powertune: that is, a modified engine calibration loaded into the Engine Control Module (ECM) that I had both engineered and installed.
In the past, GM has normally dealt with engine failures on a case-by-case basis. In doing so, it has traditionally been very fair in its approach. Engine overpower failures, that is, failures induced by a combination of customer abuse and huge power programs, are very well defined in a GM bulletin. It is much less difficult to face a customer and deny a warranty for a blown engine when we can show him exactly what happened, and why it is not GM’s fault. But what happens when an engine failure results from a source normally covered under the warranty and the owner has a chip or, as in my case, an aftermarket calibration loaded in the ECM?
