Q-Shield, from Norman G Clark , 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. They are:
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. Norman G Clark has 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 better fuel efficiency.
In addition horsepower is increased at lower RPMs. One of the 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, 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 will be, and the better the fuel consumption.
An intercooler’s effectiveness is 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. For 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 vapours 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 vapours 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 high and well within the guidelines set by the engine manufacturers.
