In this work, the performance of a Pulse-Jet valve engine was estimated numerically based on the Lenoir thermodynamic cycle. With these data it was possible to simulate and build an effective prototype in its operation. Although this type of engine has many advantages over conventional ones, it still presentes many problems for application in the propulsion of devices due to its low energy efficiency, excessive heat and high noise levels. They are engines that have a very simple construction, low cost and can operate with diferente types of fuels. Unfortunately, the high fuel consumption prevents the model from being used in a practical way. This work consists of a compilation of information about the operation of a pulse-jet, aiming to understand its construction and the real reason for its low efficiency, analyzing ways to mitigate it.
