What is a Torque Impulse Engine (TIE)? What is a clean burning 2-stroke?(TIE) Technical Analysis by John Heimbecker

A Torque Impulse Engine (TIE) is an engine whose torque function is a unique pulse train. That is, the torque delivered to its flywheel or output shaft, as a function of the angle of rotation, is a pulse train. It is this unique feature that distinguishes the TIE from other engines of today. See figure 1. Figure 1 is the uniquely distinctive torque output function of a Torque Impulse Engine (TIE). Figure 1
Figure 2 is the familiar torque output function of other engines of today. Figure 2
As an electrical engineer, inspired by modern electronic switch-mode technology, the inventor (John Heimbecker) has realized a mechanically analogous engine. The prototype is based on patent pending stroke control technology. That is, at the heart of the TIE is a unique Stroke Control Assembly (SCA). As is the case in modern electronic switch-mode technology, this unique mechanical output function implies high efficiency. With backward reference to figures 1 and 2, similarities and analogies between electronic and mechanical models may be seen. For example: First, notice the “dead-zone” in figure 1. In the electronic circuit, this is usually a region where a transistor is turned off. That is, substantially no power is being delivered to the output. This is also the case with the TIE. That is, power and torque are substantially restricted from reaching the flywheel or output shaft. Second, notice the pulse in figure 1. In the electronic circuit, this is usually a region where a transistor is turned on. That is, substantial and MAXIMUM power is being delivered to the output, during the pulse. This is also the case with the TIE. For example, this is the region where MAXIMUM torque is being delivered to the flywheel. In the TIE, MAXIMUM torque occurs at maximum mechanical advantage. Therefore, MAXIMUM power is being delivered to the flywheel throughout the majority of the power stroke. (i.e., its torque pulse width) The decaying torque pulse is a result of the exponentially decreasing pressure from the heat engine. (This may be seen with reference to thermodynamics and the Carnot or Otto heat engine cycle.) Third, older inefficient electronic circuits do not use the ON/OFF nature of the transistor. That is, the transistor is biased somewhere in the middle. This is done, in order to produce a smooth and continuous output, similar to figure 2. The cost for this smooth output is inefficiency. The transistor runs hotter than necessary. This is wasted power and energy. This is also the case with other engines of today. That is, their output functions are smooth, continuous, and inefficient. They lack an ON/OFF “duty-cycle.” For example, they have no “dead-zones.” The inherent lack of “dead-zones,” ON/OFF “duty-cycles,” and maximum mechanical advantage imply that inefficient side forces exist somewhere within these engines. In these other engines of today, these forces must be dealt with. This is not the case with the TIE. In the TIE, there are substantially no undesirable side forces and maximum mechanical advantage exists throughout the torque pulse width. |
