Working Of Hydrogen Car Engines Explained


If your memory is strong enough then you can easily recall that hydrogen is the very first element of our periodic table. It is the element whose property matches with almost all the other elements of the table to some extent. Hydrogen is the most abundant element of our universe. It is also present on earth but not in free form. Since it is very light so it remains in the form of compounds but not in free molecular form. The most abundant source of hydrogen on earth is water.

Hydrogen is an excellent fuel. It has very low ignition requirements. On burning, it generates large amount of heat and energy. It can be stored in highly compressed liquid form. It is very explosive also. NASA has used it in space shuttle propagation for years now. So there are many positives that pave the way for hydrogen the fuel to reach fuel tanks of our vehicles.

The concept of Hydrogen Cars is relatively a new concept. Although, the plans for running cars on hydrogen were laid two decades back by some scientist. The actualization of the concept into a feasible idea has come now. Automobile engineers have gained some success in designing hydrogen cars. Many prototypes are under test. However, the reality of hydrogen cars fully running on hydrogen as a fuel is still a distant reality.

Hydrogen cars are of two types. One that have an internal combustion engine with a hydrogen fuel tank. Other is that runs on hydrogen fuel cells. Some smart people have learned to use hydrogen in their gasoline operated cars even much before the purely hydrogen operated cars have been rolled out in the market. They use water in their cars to obtain hydrogen gas. A small water storage tank is accommodated in the car just around the battery.

The electrical energy of the car battery is used to split the water into oxygen and hydrogen. The reaction is known as electrolysis and the gas released is known as Brown's gas. We all know that gasoline powered engines do not burn the gasoline completely. The brown gas enhances the complete combustion of gasoline in the engine. It burns with the gasoline and produces more heat as well as energy. The hydrogen burns as normally as gasoline in the internal combustion engine of the car.

People who have tried to run their car on hydrogen from water have reported many benefits. The first and foremost is the immense gain in mileage. Users have reported gains up to 35% in the mileage of their cars. It also has reduced the emissions of the car as the incomplete combustion leads to more carbon emissions. Also it has resulted in huge savings for the users.

There are no changes required in the design of the car to run it on hydrogen. However, in purely hydrogen cars the engineers will have to upgrade the safety of the hydrogen storage tank, as it is a highly explosive gas. With the rise in oil prices and negative impact of global warming it won't be a surprise if we see more and more people switching to use water derived hydrogen to run their cars.
