QUIROGA VILLCA, Edgar. Mechanical, energetic and environmental performance tests of the 5TH generation kit natural vehicular gas feeder (NVG) for internal combustion engines, ciudad de La Paz - Bolivia . Rev. Tecnológica [online]. 2019, vol.15, n.21, pp. 24-27. ISSN 1729-7532.

Abstract  The current scenario on the use of alternative fossil fuels has promoted the inclusion in this group of natural gas under conditions of high compression, which in its technological trajectory is in the fifth generation, where the NGV control unit works with the original sensors that provide the gasoline supply, therefore indicate the volumes of NGV necessary to achieve the same power and torque as those obtained by the consumption of gasoline. Thus optimizing combustion and improving engine life time.  This last assertion has promoted a series of mechanical, energy and environmental tests in combustion engines (test and moving bench) powered by a 5th generation CNG system. Establishing that for the conditions of height of the city of La Paz, the use of this system, responds, efficiently both in old and new engines, with acceptable and economic consumption, but the same does not happen in the environmental part with the old engines, thus increasing the levels of hydrocarbons and carbon monoxide, not complying with the standard IBNORCA NB 62002, but with other parameters of air quality. In deference to the test vehicle, that reported good mechanical performance (power and torque), energy and environmental
