Recent background testing of the STIC Technology with the new STIC boost with and without the reed system.
Here are some preliminary pictures of the engine we tested at Husqvarna, Austria and Sweden with the new STIC boost system (no reeds). Zero Carbon Monoxide from 5,000 rpms to 11,000 rpms, 30% increase in HP. The STIC Boost system utilizes all of the residual pressures to effectively super charge the engine. This will be released this year 2021.
During 1985, the STIC system did not exist. However, Charles Fayette Taylor?s book: titled ?The Internal Combustion Engine in Theory and Practice? ― section: Carburetor Design and Emission control for Spark-Ignition Engines, recognizes and describes the missing carburetor link in single jet carburetors, [12]. Charles Fayette Taylor?s states: ??...The fuel-air ratio should vary as a function of the load under normal steady-running conditions. For the usual type of spark-ignition engine operating under given atmospheric conditions, the load is determined by particular values of any two of the following variables: 1) torque output, 2) speed, 3) throttle position, 4) of air flow, and 5) pressure in inlet manifold.? It is evident that the fuel-air ratio required is a unique function of air flow only at a given speed. The steady-state signal analysis varies drastically from dynamic signal analysis, especially for non-linear systems, [5]. Thus, except in constant-speed applications, an additional control, sensitive to at least one of the variables listed, must be provided if air flow is to be used as one controlling element?...?

This is precisely what the New STIC Metering Block system accomplishes, it reacts to the following, ".... 1): torque output, 2): speed, 3): throttle position, 4): of air flow, and 5): pressure in inlet manifold.? Hang on, part of it is already here in the STIC metering Block; the rest is about to arrive!
The Key to understanding new STIC discoveries.
Design Techniques for Engine Manifolds written by DE Winterbone and RJ Pearson under the heading: Future Development and Closing Remarks, address the need for the introduction of more complex gas laws, [14]. ??The application of multi-dimensional simulation techniques to unsteady flow and the simulation of transient performance of engines using wave action methods. Within section 7.1.1 General gas properties; they state the following: ?It was stated in some detail in Chapter 2 that the analytical methods for calculating unsteady flow have been restricted to perfect gases, viz. gases that obey the perfect gas law. The effect of this assumption is that changes in the properties can only be approximated by modifying the value of the ratio of specific heats, k. This approach has been used for many years in simulations based on the Method of Characteristics, where it was common to use different values of K in the inlet and exhaust manifolds. While this allows for the effect of different gas properties and temperatures on the speed of sound, it does not correctly model the manner by which energy is contained in the gas.? ?However, it is apparent that the different conditions will produce phasing changes in the waves in an engine, particularly those in the exhaust system. The effect of this will be to change the tuning speed of the waves in the pipes and this will affect the volumetric efficiency curve.?
Typical Results using the STIC technology Utilizing our natural resources and minimize waste is essential. Hence, a new approach to fuel injection and/or carburetor modification has been developed. This will enable an almost 100% burn of the fuel, [14]. This will lead to: (1): Increased horsepower and torque ? Hugely decreased emissions. 2): Decreased fuel consumption. (3): Lowering the exhaust temperature. (4): Lowering vibration levels. (5): Increased durability and life expectance of the engine. (6): Green and Sustainable concept! (7): Increased horsepower and torque since the fuel will be vaporized with better distribution, entrained with the oxygen, for a more total burn.
The STIC Metering block when applied to a stock engine will change the effective horsepower and torque since more of the energy within the fuel will be utilized. The empiric research data results presented, have been accomplished by certified independent external laboratories throughout the world.
This is evidenced in the following videos with the STIC installed into a stock YZ125X. Cheers
