The diesel hybrid combustion engine essay

Automakers Grew EV Sales by Percent in June Early on, Tesla recognized that responses to climate change were necessary — not just from individuals and governments, but also from industry. And Tesla realized that, when mated with wind and solar energy, electrical vehicles could become a powerful force for driving an energy transition capable of rapidly cutting global carbon emissions.

Stop reading now, and ponder the table of energies. Concentrate on the last column. Look for the numbers that are surprising. How many can you find? My answers are below. I think all of the following are surprises: Even most physics majors will be surprised.

These surprises and some other features of the table are worthy of much further discussion. They will play an important role in our energy future. When TNT is exploded, the forces push the atoms apart at very high speeds. One of the biggest surprises in the energy table is that chocolate chip cookies CCCs have eight times the energy as the same weight of TNT.

How can that be true? That includes most physics majors. What makes TNT so useful for destructive purposes is that it can release its energy transfer its energy into heat very, very quickly. The heat is so great that the TNT becomes a gas that expands so suddenly that it pushes and shatters surrounding objects.

A typical time for 1 gram of TNT to release all of its energy is about one millionth of a second. Such a sudden release of energy can break strong material.

Power is the rate of energy release. Even though chocolate chip cookies contain more energy than a similar weight of TNT, the energy is normally released more slowly, through a series of chemical processes that we call metabolism. This requires several chemical changes that occur during digestion, such as the mixing of food with acid in the stomach and with enzymes in the intestines.

Finally, the digested food reacts with oxygen taken in by the lungs and stored in red blood cells. In contrast, TNT contains all the molecules it needs to explode; it needs no mixing, and as soon as part of it starts to explode, that triggers the rest.

If you want to destroy a building, you can do it with TNT. Or you could hire a group of teenagers, give them sledgehammers, and feed them cookies. Since the energy in chocolate chip cookies exceeds that in an equal weight of TNT, each gram of chocolate chip cookies will ultimately do more destruction than would each gram of TNT.

Note that we have cheated a little bit. If we were to include the weight of the air, the energy per gram would be lower, about 2. The surprisingly high energy of gasoline As the energy table shows, gasoline contains significantly more energy per gram than cookies, butter, alcohol or coal. This fact will be important when we consider alternatives to gasoline for automobiles.

Visit PhysicsCentral.com Diesel conversions[ edit ] Diesel engine is compression ignition engine and does not have spark plug.

Gasoline releases its energy turns it into heat by combining with oxygen, so it must be well mixed with air to explode. In an automobile, this is done by a special device known as a fuel injector; older cars use something called a carburetor.

The explosion takes place in a cylindrical cavity known, appropriately, as the cylinder.The Diesel Hybrid Combustion Engine Essay - The Diesel Hybrid Combustion Engine Two main types of engines powering everyday machinery are diesel and gasoline internal combustion engines.

Both vary on efficiency levels, but are still effective. Diesel engines have high efficiency levels, such as producing great amount of torque at very low rpms. Yahoo Lifestyle is your source for style, beauty, and wellness, including health, inspiring stories, and the latest fashion trends.
