What is the purpose of the spark plug?

It ignites the compressed air/fuel mixture.


Why does it smell like gasoline by the spark plugs?

Basically it means your fuel to air mixture is to rich (too much fuel and too little air), meaning that you are getting an incomplete burn of the fuel drawn into the cylinder for each cycle. It could also mean that you are not getting a hot enough spark (to ignite the mixture) thus leaving too much of the fuel unburned.

What change occurs in the fuel air mixture when carburetor heat is applied?

It get's richer, The fuel/air mixture becomes richer..

How do you fix rich air fuel mixture?

install a cold air intake. more air with same amount of fuel being injected will lean out the fuel/air mixture. plus you'll get more power


What is the function of the spark from the spark plug?

The purpose of the spark is to ignite the air fuel mixture in the combustion chamber. When the air fuel mixture ignites the expansion of the burning air fuel mixture causes the piston to go down thus turning the crankshaft.


Define mixture strength in combustion?

Mixture strength in combustion refers to the ratio of fuel to air present in the air-fuel mixture. It can impact the efficiency and performance of the combustion process, with a stoichiometric mixture (ideal ratio of fuel to air) typically providing optimal results. Adjusting the mixture strength can affect factors like power output, emissions, and fuel economy in combustion engines.


In a diesel engine the air fuel mixture is ignited by?

It is ignited by compression. The air fuel mixture is compressed by the piston going up. Some diesels have glow plugs too that heat up the air fuel mixture so it is more easily ignited.


What are the methods used to control fuel and air mixture in carburetor?

The methods to control the fuel and air mixture in a carburetor include needle valves to control fuel flow, and the butterfly or ventura to control air flow.


What properly tuned exaust system prevents the air fuel mixture from leaving with the exhaust?

A properly tuned exhaust system optimizes backpressure, which helps to keep the air-fuel mixture in the combustion chamber for a longer duration, allowing for more efficient combustion. This is achieved through the design of the exhaust headers, pipe diameter, and muffler configuration, which work together to enhance exhaust flow while maintaining the necessary pressure. By preventing the premature escape of exhaust gases, the system ensures better engine performance and efficiency.
