The vehicle, fitted with a hydrogen fuel cell device, is essentially a conventional railway car with an onboard power generation to produce the phenomenon called hydrolysis, whereby two molecules of hydrogen and oxygen are separated to produce a gas highly volatile. Academic IPN participating in this project are Abel Israel Tristan Calera, Mario Christopher Yahuaca Diaz, Pedro Castillo Martinez and Carlos Enrique Garnica Cruz, career Technician Automotive Systems.
Tristan Calleja explained that the car does not suffer changes because the system consists of a water tank, a hydrolyser and a filter which counteracts excessive moisture through a hose hydrogen is introduced by the intake system, whose task is to provide large amounts of clean air to the engine to turn stressed that the prototype has its own security system, because hydrogen is a gas having the characteristic of being flammable. If a flare occurs in the ignition switch that cut the fire before it reaches the fuel tank is activated.
Perhaps the greatest challenge in this prototype was the machining of hydrolyzer and although at first glance is a simple device consisting two plastic and more metal plates, we had to perform a series of trial and error until you find the materials and size appropriate to introduce it to the ignition system of the car suffered no damage “said Tristan Calleja, who is also professor of course in UPVM He said that the hydrogen-producing device has been included in three cars with different dimensions:
Grand Caravan, Autos and currently tested in a Nissan Tsuru 2001 with 1.6 liter engine that runs as a taxi. In the unit there have been savings in fuel consumption because the hydrogen is more volatile and stabilizes the motor.
We have found several advantages to this device we reduced by up to 20 percent gasoline use and pollution to the environment and the characteristic odor of combustion vibration and engine noise. Meanwhile, the student Ricardo Flores Rodriguez, sixth semester student career Mechatronics Engineering of UPVM said the approximate water used for this type of car is a gallon.
Nearly four liters for five days even though it is a taxi which has become more stable because the catalyst no longer works so the engine heats up less and emissions are lower because now uses a percentage of hydrogen to run, “he said fuel economy has positively impacted in the pocket of the taxi business and plans to raise using hydrogen in a second draft, which will be necessary to go into the engineering applied to engines and optimize the hydrogen generator.
Everything can be changed. In older cars only hydrogen is injected directly to the carburetor and would issue in modern sensors study to lower or increase the flow of hydrogen in accordance with the strength required by either capacitive or inductive; with respect to air flow of gasoline, it would depend on the type of car.
