Q-SHIELD™
Q-Shield is a patented technology that significantly reduces the consumption of diesel fuel or gasoline in internal combustion engines. Q-Shield™ technology employs space-age Thermal Insulators to key parts of the engine. It does not invade any engine components. Q-Shield™ is fitted to the total air intake system: compressor, turbocharger, exhaust manifold, and intercooler. This total shielding produces a more complete combustion rate. Q-Shield™ operates in engine types with or without intercoolers.
By protecting the air intake system from excessive heating, the air reaches the combustion chamber at lower temperatures. This produces denser air leading to a more complete combustion and much better fuel efficiency.
In addition horsepower is increased at lower RPM’s. A benefit of using Q-Shield™ is the reduction of air pollutants; consuming less fuel and producing fewer emissions. The process increases the heat in the exhaust system which burns off excessive particulates.

Engines with intercoolers
Intercoolers produce cooler and denser air prior to entry into an engine’s combustion chamber. The denser the air the more complete the combustion rate, and the better the fuel consumption.
An intercooler’s effectiveness is greatly reduced when it is exposed, without insulation, to the excessive heat emanating from various heat producing engine components, producing hotter thinner air resulting in a reduced combustion level, thereby increasing fuel consumption.
Q-Shield™ improves the intercooler’s performance and reduces fuel consumption.
Engines without intercoolers
Q-Shield™ technology prevents intake air from heating prior to entry into the combustion chamber.
In an internal combustion system, ambient air initially passes through the air filtration system, located in the engine compartment which are subject to a build-up of heat. The Q-Shield™ system reduces the heat by covering the air box and air intake conduit with thermal insulators.
The air then enters the compressor, which is covered by a Q-Shield™ to further maintain the temperature of air. Maintaining cooler air results in an increase in the air density. The air then leaves the compressor, passes through the hot air inlet pipe, which is also covered by thermal insulators.
The air then enters the combustion chamber in which the air combines with the fuel and is ignited. Since after installation of the thermal insulators, the cooled air is denser, substantially higher amounts of fuel are burned, resulting in the benefits described above.
Engines with turbochargers
Exiting the combustion chamber, unspent fuel and vapors enter the turbocharger which is partially covered by a Q-Shield™. This controls the heat in the turbocharger increasing combustion of exhaust gases. Exiting the turbocharger, the reduced unspent fuel and vapors are expelled through the exhaust system, covered by insulators to maintain the heat, which in turn burns more pollutants.
Effect of Q-Shield technology on engine metal and oil temperatures
Extensive temperature testing has been performed to insure that no components of the engine that are covered with thermal insulators are damaged in any way. The results of these tests warrant that increases in metal and oil temperatures are modest and well within the guidelines set by the engine manufacture.

Q-Shield™ Thermal Insulators For Heat Management In Automotive and Industrial Applications.
Controlling and managing heat is a challenging issue facing many aspects of modern industry. Traditionally, significant reductions in the transfer of heat required the use of very thick, bulky materials that were difficult to install, maintain and service. Given that the nature of many current applications provide only very limited space may to install insulating materials, and as such, a new approach had to be taken to meet the challenge of high performance heat management and space constraints. Q-Shield ™ thermal insulators are comprised of high-performance proprietary multi-layer materials. The high efficiency and small cross section thermal insulating materials employed in Q-Shield ™, produce significant reductions in heat transfer even where there are stringent space constraints. Given space constraints, we can meet heat reduction requirements with custom-designed compact, high-performance thermal insulating products.
There are 3 primary areas of applications for Q-Shield ™ thermal insulators for heat management:
-
Underhood Engine Heat in Automotive Applications
-
General Automotive Insulation Applications
-
Industrial Applications
-
Sound Proofing Applications
Underhood Engine Heat Management for Automotive Applications
Over the last few years, heat generated in truck and bus engine compartments has considerably increased as a result of design changes made by engine manufacturers which was necessitated by new EPA regulations to reduce emissions. As emission regulations became stricter, engine heat has increased sharply.
In 2004 when EGR technology was mandated by the EPA, underhood heat increased by approximately 30%, and when the Diesel Particulate Filters (DPF) were required in 2007 engines, underhood heat increased by an additional 20–30%. These two developments have resulted in an overall increase in underhood heat of approximately 60%.
Extensive component failures have been widely reported, as a result of the introduction of EGR. Such components include: hoses, fuel lines, alternators, air filter canisters, belts, seals, and engine wiring. High engine compartment temperatures have caused grease and other lubricants in the bearing systems to break down, resulting in the failure of alternator bearings, idle puller bearings, and fan hub bearings.
Many of the heat problems caused by the introduction of EGR have by now been solved, but with the introduction of the 2007 engine requirements, further increases in underhood temperatures can be expected with another round of problems of a comparable magnitude to those that were faced when EGR was first introduced.
The answer: American Diesel & Gas, Inc.’s Q-Shield™ technology can significantly contain underhood engine heat and protect components from the heat generated by the engine, with compact, high-performance Q-Shield ™ thermal insulators that can be easily and quickly installed, later removed and reattached as may be required.
