Military forces headquartered at the United States Pentagon are the single largest oil consumers in the world.  The amount of oil consumed is staggering, and exceeds that of entire countries. For example, 40,000,000 gallons of fuel were burned in just three weeks of Desert Storm in Iraq. This is an amount equivalent to all the gasoline consumed by all Allied armies combined during the four years of World War I. Battlefield cost was up to $438 per gallon.

The problem is simple. The 1942 jeep internal combustion engine is the same basic design used in military vehicles today.  Worse, standardization to J-8 fuel for a wide variety of vehicles does not allow many of them to operate with optimal efficiency, resulting in poor performance, high maintenance, noisy operation, and poor fuel economy.


Dependent on a vulnerable supply line carrying specialized fuel, military logistics and tactics have been constrained for nearly a century.  Although the military has experimented with electric and hybrid powertrains, neither are practical for the intended use.

Powering a military vehicle with a ZED engine however would greatly redefine ground warfare.

The Top 10 advantages would be:

  1. No starter. The ZED engine is self-starting, and does not “idle”. When the vehicle stops, the engine stops for total silence, a distinct combat advantage.
  2. No exhaust muffler. Fuel is burned quietly and continuously, so there are no combustion explosions to muffle. This allows quiet, stealth operation of all vehicles at all times.
  3. No air filter because combustion is external. This means that a vehicle can burn fuel and operate in the worst sand storm, torrential rain, snow storm or other adverse condition with mechanical impunity. No contaminants can be ingested in the ZED engine, unlike conventional engines.
  4. Combustion is external to the engine cylinder. No fuel is delivered into the power cylinders, therefore lubricating oil is not dissolved or contaminated. This feature greatly reduces wear, operating damage and maintenance.
  5. Any available fuel can be used to maximize battlefield logistical and tactical efficiency. This means that fuels can be scavenged on-site, as well as mixed randomly, without affecting vehicle performance, or depending on supply lines. This maximizes operational flexibility.
  6. No radiator cooling system. The power cylinders do not have to be cooled like a traditional engine. This means that the engine can operate in extreme heat with mechanical impunity.
  7. No internal cooling passages in the engine block. This means that the engine can operate in extreme cold without concern of freeze up, even if it is shut down in the coldest arctic temperature.
  8. No heat trail or exhaust plume in the battlefield as exhaust heat is scavenged for mechanical work before being discharged widely at near ambient temperature.
  9. Increased operating efficiency from being able to maintain optimal stoich (fuel/air ratio) at all engine speeds, loads and temperatures which results in better fuel economy and far lower emissions.
  10. Maximum power at less than 500 RPM means rapid throttle response, and typically double the torque from the same size engine, which results in heavier duty operation and durability.

Derived from current piston engine design, ZED is the only high efficiency engine which can be built in existing production plants and installed in existing military vehicles. ZED preserves billions of dollars of forge, casting, machining and assembly facilities as well as billions of dollars invested in vehicle design.

In unique designs such as the M-1 battle tank turbine powerpack, the ZED engine offers an alternative which is immune from sand abrasion in the engine as well as high ambient heat.
