Combustion Reaction : 

Combustion Reaction Tag Choi

What are the different types of chemical reactions : 

What are the different types of chemical reactions Combustion Decomposition Synthesis Single Displacement Double Displacement Acid-base

What is a combustion reaction? : 

What is a combustion reaction? It takes place when a fuel and an oxidant react, producing heat or heat and light.

What is the fire triangle? : 

What is the fire triangle? A model for understanding the ingredients for most fires It also called combustion triangle

What is activation energy? : 

What is activation energy? It is energy that mush be overcome in order for a chemical reaction to occur

Why is heat/energy a necessary part of the fire triangle? : 

Why is heat/energy a necessary part of the fire triangle? Because the fire is hot which mean is that fire has heat

How is the Cooktop of your stove (not electric) a real-life example of a fire triangle? : 

How is the Cooktop of your stove (not electric) a real-life example of a fire triangle? It has gas so that make fire. The cooktop of my stove produces heat

What is a combustion engine? : 

What is a combustion engine? The internal combustion engine is an engine in which the combustion of a fuel (generally, fossil fuel) occurs with an oxidizer (usually air) in a combustion chamber. An external combustion engine (EC engine) is a heat engine where an (internal) working fluid is heated by combustion of an external source, through the engine wall or a heat exchanger.

(In general)How does a combustion engine work? : 

(In general)How does a combustion engine work? With an internal combustion engine, fuel is burned inside the engine in what is known as a combustion chamber. The combustion chamber is an enclosed space where the gasoline goes. Once the gas of the confined gasoline expands, it produces energy

In terms of combustion, how are NASCAR engines different from street car engines that allow them to operate at much higher speeds? : 

In terms of combustion, how are NASCAR engines different from street car engines that allow them to operate at much higher speeds? The displacement is large -- 358 cubic inches (5.87 liters). Not many cars have engines this big, but the ones that do usually generate well over 300 horsepower. The NASCAR engines have extremely radical cam profiles, which open the intake valves much earlier and keep them open longer than street cars. This allows more air to be packed into the cylinders, especially at high speeds (see How Camshafts Work for more details). The intake and exhaust are tuned and tested to provide a boost at certain engine speeds. They are also designed to have very low restriction, and there are no mufflers or catalytic converters to slow the exhaust down either. They have carburetors that can let in huge volumes of air and fuel -- no fuel injectors on these engines. They have high intensity programmable ignition systems so the spark timing can be customized to provide the most possible power. All of the subsystems like coolant pumps, oil pumps, steering pumps and alternators are designed to run at sustained high speeds and temperatures.

How does nitrous oxide help engines perform better? : 

How does nitrous oxide help engines perform better? you have more oxygen, you can also inject more fuel, allowing the same engine to produce more power. Nitrous oxide is one of the simplest ways to provide a significant horsepower boost to any gasoline engine.

Provide 1 documented example of cheating in NASCAR in which something was done illegally to increase the combustion performance of the engine : 

Provide 1 documented example of cheating in NASCAR in which something was done illegally to increase the combustion performance of the engine The No. 18 and No. 20 Joe Gibbs Racing teams in the Nationwide Series will likely face big penalties after efforts to alter the results of a chassis dyno test
