What is the effect of HHO on an internal combustion engine
Introduction [200 words]
What is an internal combustion engine
Combustion, also known as rapid burning, is the basic chemical process of releasing energy from any fuel and air mixture. In an internal combustion engine, the ignition and combustion of the fuel occurs within each cylinder of the engine block. The engine then partially converts the energy from the combustion to push the piston down. The engine consists of a fixed cylinder and a moving piston (Springfield.mntm.org, 2017). The expanding combustion gases push the piston, which in turn rotates the crankshaft. Ultimately, through a system of gears in the powertrain, this motion drives the vehicle’s wheels

These benefits include; environmental, money saving, longer lasting engines etc. HHO eliminates harmful exhaust emissions that pollute the environment, meanwhile not contributing to global warming (Drive60mpg.com, 2017). Within the experiments that I conducted, I discovered that supplying HHO to an engine had created many new and different advantages, which provide better outcomes.

When the HHO is fed into the air intake, then into a cylinder, the hydrogen explosion is so rapid, that it achieves total combustion upwards of three times faster than a gasoline based explosion (Saisantosh et al., 2017). This subsequently ignites the gasoline from all directions (For example, putting fuel on a fire), instead of just a spark in one end of the combustion cylinder. Hydrogen behaves like this because it has a very wide flammability range-from 4% to 75% in air (Duncan, 2017) . Due to this there is a release of energy in a short period of time, causing the mixture to get hot and greatly expand in volume (Saisantosh et al., 2017). If the fuel is not fully burnt in that short amount of time then it just goes out the exhaust and is lost. It is also best to ignite all of the gasoline when it is under maximum compression in a combustion cylinder to get the maximum amount of energy out of it (this is a small time window). Once the piston starts going down, the energy transfer from the explosion to the
Combustion Reaction: A chemical reaction between a fuel and an oxidizing agent that produces heat.
The invention of the internal combustion engine sprouted from the work of several engineers and inventors across Europe and into America. First, in 1859, Jean-Joseph Etienne Lenoir developed the first practical internal combustion engine which after many modifications and changes, led to the modern engine that plays a crucial role in today’s society. Prior to Lenoir, external combustion engines such as the steam engine and early hydrogen engine
The continuing rotation of the crankshaft drives the piston back up, ready for the next cycle. The piston moves in a reciprocating motion, which is converted into circular motion of the crankshaft, which ultimately propels the car. Gas engines usually have about the same about of horsepower as they do torque. The diesel engine usually has twice as much torque as it does horsepower, thus it is the better hill climber and load carrier.
In a combustion reaction, a compound or element reacts with oxygen, releasing a large amount of energy in the form of light and heat.
Hydrogen fuel cell vehicles (fcvs) have not been around for long, but over the past decade that have developed into a new potential successor of the combustion engine. Fcvs function the same as an electric cars but the difference is the hydrogen fuel cell stack. Hydrogen fuel stacks are just multiple layers of fuel cells stacked up and when hydrogen is pumped in to mix with oxygen a reaction takes place. From this reaction electricity and water vapor is created. The electricity carries on and powers the electric motor(s) in the car. The vapor is released from the exhaust and since only water vapor is released, no harm is done to the environment.
The use of a hydrogen fleet, would solve many of the existing emissions issues associated with diesel fuel usage. ”Vision Motor calls their hydrogen tractor a Zero Emissions Terminal Tractor, or ZETA. It's the right thing for southern California because of its benefits to people's health, says LaRosa, citing lung and respiratory diseases blamed on exhaust smoke from internal combustion engines.” (http://www.truckinginfo.com/article/story/2012/04/hydrogen-fuel-cells-could-be-socal-fleets-future.aspx) Hydrogen offers no emissions in the air other than vapor, and fuel economy is better than most gasoline powered vehicles, roughly in the 30-50% range. Currently hydrogen is very costly to produce, and there isn’t enough infrastructure to support a full fleet of
All internal combustion engines rely on the combustion of a chemical fuel. This process normally outcomes in the production of a large quantity of
A car fueled by a typical gasoline engine runs differently than an electric. Instead of having a battery to power the engine, the car uses an internal combustion unit to propel the car. The gasoline that the owner adds to the vehicle is heated by the combustion unit and is mixed with oxygen to power the engine. When the driver pushes the pedal down, that activates the combustion unit.
The burning of propane is a Combustion reaction. It’s an irreversible reaction. This type of reaction occurs when a hydrocarbon reacts with oxygen to produce water and carbon dioxide. Oxygen is the reactant
There is an explosion just as the piston is at its highest point, and the volume of the chamber is its lowest. This phase is called combustion. The force of this explosion pushes the piston down, and then up again as a second valve opens, pushing the exhaust out and into the air. This final phase is called exhaust. As the piston moves down again, the cycle repeats.
The piston then travels down pulling in fresh air, (third stroke), after the piston bottoms again it travels up compressing the fresh air, (fourth stroke). The fuel is then injected and one cycle is completed in 720 degrees or two full rotations of the crankshaft.
The invention and use of the internal combustion engine was a pivotal point in the history of the automobile. The first attempt at an internal combustion engine was in 1673 by Christian Huygens, using gunpowder as the fuel source, though it was basically worthless as you had to open the engine up and put new gunpowder in it after every single stroke ("The Fuel & Engine"). This lack of a fuel for internal combustion engines sidelined its development for a couple hundred years. In 1860 Jean Joseph Etienne Lenoir built the first effective internal combustion engine using natural gas (Bottorff). The ignition of the gas would create a vacuum and the resulting pressure difference between the vacuum and the atmosphere would drive the power stroke (Bottorff). This gas-atmospheric engine, as it is known, was an effective system capable generating 20hp, still it was imperfect. It was further improved with the development
Conventional cars use internal combustion engines to generate power to put the car into motion. All conventional cars use what is called a “four-stroke combustion cycle” which are “intake
We've all seen them before, the mysterious chunks of metal under the hoods of our cars. They start when we turn the key and take us where we want to go. But how does an engine work? Internal combustion engines are a very important part of everyday life. We use them in our cars, trucks, airplanes. boats, snowmachines, 4 wheelers, and heavy machinery. These pages will help familiarize you with the basic concepts of how an engine works, an understanding of engine output, and some information on how forced induction or "boost" increases power output.
In order to understand the why behind the need to change from fossil fuels to hydrogen power, it is necessary to understand what that power is and how it works. Hydrogen is the most abundant and simplest element on earth. It is most commonly found as part of water. In its pure gaseous form it is extremely light, but when ignited in this state releases a large amount of energy in an explosion. In this violent reaction the hydrogen combines with free oxygen molecules in the atmosphere and creates water vapor. This is similar to the way gasoline is combined with air and ignited in an internal combustion engine in the cars used today and like with gasoline, the combustion of hydrogen has risks. In addition to the risk, some of the energy released in the reaction is lost in the form of sound and heat. As an alternative to burning, these same gases can be combined with the use of catalysts to extract the free electrons produced as liquid water is formed(Popovici and Hoble Dorel). Using cables connected to a fuel cell such as this, those electrons go through a circuit, generating electricity. This is more efficient than combustion because less energy is wasted in the form of sound and heat. Going further, greater efficiency for this reaction can be had the lower the temperature it is allowed to take place at, with 83% power at 25◦C(77◦ F)(Popovici and Hoble Dorel). As fuel cells are created with better heat management and
