Although not yet in every day application, there are several different kinds of six-stroke prototypes sporting impressive test results. The most promising of these designs however, appears to be Bruce Crowers design which uses steam to generate a second power stroke.Normally after the power stroke in a normal four-stroke cycle the immense heat from the explosion is dealt with by a radiator. This isnt only inefficient because of the excess weight of a cooling system, but since upVIEW DOCUMENT

The six-stroke engine is an ingenious invention that has the potential to increase engine efficiency by around 30 percent. As fossil fuels are increasingly more expensive to produce and utilize, many have been seeking for answers to these problems. The six-stroke engine seeks to solve some of these problems by exploiting heat that would normally be lost in the four-stroke engine. It does this by utilizing an extra pump to produce more torque and power. In the following graph, the conventional four-stoke is compared to a 6-stroke using a Yamaha TT 500c.

Friction between the cylinder wall and the sides of the piston creates resistance and heat, some of the ignition heat conducts through the cylinder wall and is not used for power, and the ignition itself can not be relied upon to actually burn all the fuel brought into the cylinder.
A properly tuned engine should effectively burn up most of the gas in the cylinder and transfer a majority of the
force into propelling the piston into its power stroke, but if an engine is timed wrong, serious power losses can be experienced and resources will be wasted. In the ignition stroke, the compressed mixture should ignite a few degreesVIEW DOCUMENT

Heatstroke in considered dangerous due to the high incidence of fatality associated with heatstroke.

927 words - 4 pages compression of the air charge in the cylinder (p1 Makartchouk).
There are basically two types of diesel engines, two-stroke and four-stroke. In a two-stroke engine the piston is forced from the top of the cylinder by the expanding air fuel mixture. Before the piston reaches the bottom of the cylinder the used mixture, (called exhaust), is forced out of the cylinder by the incoming fresh air. The fresh air relies upon a blower, air induction system, to propel it into the combustion chamber. During this time period the piston begins to travel to the top of the cylinder and compress the fresh air sufficient to raise the temperature in the combustion chamber, (area between the top of the cylinderVIEW DOCUMENT

To mitigate these detrimental effects, powerful physiological mechanisms are evoked, including cutaneous vasodilation and whole body sweating which facilitates enhanced heat dissipation into the surrounding environment (Charkoudian, 2003).

2625 words - 11 pages but they work slightly different. The difference between the two engines is the way in which the fuel explodes during the combustion cycle. A gasoline engine has to use spark plugs to make the fuel explode where a diesel engine does not. On the first stroke of the combustion cycle of a diesel engine air is let into the cylinder and the second stroke compresses the air. When air is compressed it will heat up which will ignite the fuel on the third stroke driving the piston back down and then the fourth stroke pushes out the exhaust. Both the diesel engine and the gasoline engine have a four-stroke combustion cycle but the gasoline engine has to have the spark form the spark plugs to igniteVIEW DOCUMENT

If you do not drink enough fluids when you exercise then there is a possibility of having heat exhaustion, heat cramps, or a heatstroke.

The Compression stroke begins when the intake valve closes and the piston starts its upward stroke. It is crucial that piston rings function properly to reduce the ammount During this time the volume of the cylinder is decreasing thus compressing the air inside the cylinder.This compression greatly increases the temperature of the air in the cylinder which will allow the air to ignite the diesel fuel when it is to be injected(Diesel Power Magazine)..
During the power stroke, fuel is injected into the highly compressed air and the mixture combusts. This combustion of fuel generates a massive amount of heatVIEW DOCUMENT

Hypothermia is when the body temperature drops too low, and it starts shutting down functions and extremities. If subjected to cold weather for an extended period of time, a person’s mind tends to start slipping. They may forget simple things like how to get food or water, and eventually they may forget their main goal: survival. The opposite of cold is hot, and heat is just as dangerous as cold with a multitude of underlying difficulties. With heat comes new challenges like heat exhaustion and heatstroke that have to be overcome or the probability of survival drops significantly. Heat exhaustion and heatstrokeVIEW DOCUMENT

The purpose of this paper is to investigate the correlation between ethnic minority groups and the heat wave, specifically focusing on African-Americans and Latinos.

Usually, the body perspires and is cooled through the evaporation of that perspiration.

The elderly, the young, the overweight, and the infirm are vulnerable to heatstroke, as are people who have been overexposed to the heat, or have over-exercised for their age and physical condition.

A mixture of air and gasoline enter through the intake valve into the combustion chamber. The second stroke is called compression. The intake valve closes and the piston compresses the mixture.

On August 2, 2006, a fifteen year old high school freshman died from a heatstroke after offseason workouts. This led to counties and parishes having the power to cancel practices to due extremely high heat indexes. Coaches often say that during practice water makes you weak, states have stopped this by requiring water breaks every thirty minutes.

3267 words - 13 pages between gas and diesel engines. A diesel engine does not need spark plug to ignite the fuel. It takes in air, compresses it then injects fuel into the compressed air. The high air temperature ignites the fuel. On the other hand, a gas engine takes in a mixture of air and gas, compresses them, and ignites them using a spark plug. Another difference is the process of injection. Most gas engines use port injection, where the air, as well as the fuel go in the cylinder during the intake stroke and then compressed. There is a limit in the compression of the air and fuel mixture because if the air is compressed too much, the mixture will naturally ignite. On the other hand, diesel engines use directVIEW DOCUMENT

According to Glaser, Davidson, and Csigi (1993), solar power systems can also be designed using mirrors or lenses to concentrate sunlight onto a thermal receiver.

Systems of this type can store power in the form of heat, instead of requiring batteries, but have not yet been used in space.
