Norman G. Clark showcases Q-Shield™ - Space-age technology at its best!

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.

There are 3 layers that make up the Q-Shield™ Thermal Insulators. Layer 1 - the outside. It is made up of aluminized space-age material. Layer 2 - the middle. Specialized, thick glass fibre insulation. Lastly, layer 3 - the inside. It is a superior, heat-resistant material. Iconel wire is applied on the bottom of the shields for certain engine components such as the turbocharger and manifold.

For typical truck and tractor applications, the Q-Shield™ technology can withstand up to 1000°F. We have Q-Shield™ kits for other applications, such as locomotives and GenSets, which are rated in excess of 2,000 and 3,000°F.

Q-Shield™ 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. One of the many benefits 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.

Q-Shield™ can be applied to any type of engine regardless of engine manufacturer.  Such major engine makes Q-Shield™ caters for are Caterpillar, Cummins, Isuzu, Mack, Mercedes, Mitsubishi, Nissan and Volvo – to name a few, with plenty more engine type fittings available. 

Q-Shield™ will support all types of combustion engines, whether in a moving industrial vehicle, generator, or marine engine. There is no internal combustion engine that will not benefit from the Q-Shield™ technology.

On the matter of fuel consumption improvement - diesel engine vehicles should improve between 10-20%, and petrol vehicles between 20-30%.



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.

The design improves the intercooler’s performance and reduces fuel consumption – which in today’s age, we can all be happy about!

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 is 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 manufacturers.
