Can hydrogen be used in an internal combustion engine?

Hydrogen has a wide flammability range in comparison with all other fuels. As a result, hydrogen can be combusted in an internal combustion engine over a wide range of fuel-air mix- tures. A significant advantage of this is that hydrogen can run on a lean mixture.

Why hydrogen is not popular in IC engine?

First, hydrogen is not as energy-dense as other fuels, meaning that you need a whole lot of it to do a little bit of work. Couple that with the inherent inefficiency of a piston engine (at best, you’re only turning about 30 percent of the fuel’s energy into forward motion), and you’ve got a recipe for disappointment.

Can petrol cars run on hydrogen?

Modern direct-injection turbocharged hydrogen engines can produce more power than an equivalent petrol engine by increasing the proportion of hydrogen in the fuel-air mixture – but the NOx levels increase. Hydrogen can be stored in the same well-proven 700-bar compressed gas tanks used in fuel cell vehicles.

Which is disadvantage in using hydrogen as a fuel in internal combustion engine?

Disadvantages of hydrogen fuel Flame temperature of hydrogen is high, so the emission of NOx also high. Poor volumetric efficiency – When the fuel in gaseous state used in IC engine, the fuel displaces the equal volume of inlet air inside the engine cylinder and poorer volumetric efficiency will be the result.

Is hydrogen fuel a gas or liquid?

Hydrogen is a gas at normal temperature and pressure, but hydrogen condenses to a liquid at minus 423 degrees Fahrenheit (minus 253 degrees Celsius).

Do hydrogen cars produce NOx?

Hydrogen does not contain carbon. However, hydrogen combustion with air produces oxides of nitrogen, known as NOx, against emission regulations. In this way, the combustion process is much like other high temperature combustion fuels, such as kerosene, gasoline, diesel or natural gas.

What are the disadvantages of internal combustion engines?

Even in cases of hybrid vehicles, they still use an internal combustion engine to charge the battery. The disadvantage is the pollution that they put out. Not only the obvious, air pollution, but also pollution of broken or obsolete engines and waste parts, such as oil or rubber items that have to be discarded.

What are the uses for an internal combustion engine?

The internal combustion engine mostly uses in the road and heavy vehicles such as scooters,motorbikes,buses,etc.

  • Also used in the airplanes.
  • These types of engines use in different motorcycles.
  • Internal combustion engines use in marine boats.
  • How does combustion work in an internal combustion engine?

    Intake stroke. As the piston moves downwards the inlet valves open up and because of suction the air is drawn inside the cylinder.

  • Compression stroke.
  • Combustion stroke.
  • Exhaust Stroke.
  • Component of an internal combustion engine
  • Engine Block.
  • Spark Plug.
  • Valves.
  • Piston.
  • Piston rings.
  • What are the different types of internal combustion engines?

    Types of Internal Combustion (IC) Engines. There are two main types of IC engines: spark ignition (SI) engines (petrol or gasoline engine) and compression ignition (CI) or diesel engine. Both these engines are further classified as 2-stroke and 4-stroke engine.
