When a spark ignites the mixture of gas and fuel in a four stroke engine stored chemical energy is converted to blank energy?
When a spark ignites the mixture of gas and fuel in a four-stroke engine, stored chemical energy is converted to thermal energy, which causes the gas and fuel mixture to burn and expand rapidly, generating mechanical energy that powers the engine.
In which step of the four -stoke engine cycle does the spark plug initiate the combustion reaction?
The spark plug initiates the combustion reaction during the power stroke of the four-stroke engine cycle. This occurs after the compression stroke, where the air-fuel mixture is compressed, and the spark plug ignites it, causing an explosion that drives the piston down. This process converts the chemical energy of the fuel into mechanical energy.
Which form of energy does a car's engine convert into mechanical energy?
A car engine converts the heat energy contained in the hot high-pressure gases in the cylinder into mechanical energy. The heat comes from the formation of chemical bonds between carbon and oxygen, and between hydrogen and oxygen, when the hydrocarbon fuel is burnt with the air in the cylinder at the top of each power stroke.
Describe each part of a four stroke engine in your own words. What each part does?
The various parts of a stroke engine basically work in unison in converting the thermal energy to mechanical energy.
Advantages of two stroke engine over a four stroke engine?
Explain the advantages of four-stroke engine over two-stroke engine
What causes the power stroke?
The power stroke in an engine is caused by the rapid expansion of gases from the combustion of fuel within the combustion chamber. When the fuel-air mixture ignites, it creates high-pressure gases that push the piston down, converting chemical energy into mechanical energy. This downward movement of the piston is what generates power for the engine's operation. The entire process is a critical part of the engine's cycle, enabling it to produce the necessary force to drive the vehicle.
Which engine was invented first.Two stroke engine or four stroke?
two stroke
Why is four stroke ingine is internal combustion?
A four-stroke engine is classified as an internal combustion engine because it generates power through the combustion of fuel and air within a confined space, typically the engine's cylinders. During its operation, the engine goes through four distinct strokes: intake, compression, power, and exhaust, all occurring within the cylinder. This internal process allows the engine to convert the chemical energy from fuel into mechanical energy, driving the vehicle or machinery. The combustion occurs internally, hence the term "internal combustion engine."
Why fuel consumption is less in 4 stroke engine then in 2 stroke engine?
Why the fuel consumption is less in 4 stroke engine as compared to 2 stroke engine
WHAT IS expansion stroke?
The expansion stroke is a phase in the four-stroke engine cycle where the combustion gases expand, pushing the piston down in the cylinder. This occurs after the power stroke, where the fuel-air mixture has been ignited. During this stroke, the piston moves from the top dead center to the bottom dead center, converting thermal energy from combustion into mechanical energy. This process is essential for generating the power needed to drive the engine.
What is better a four or two stroke engine?
in my opinion a two stroke engine is a better quality engine as compared to a four stroke engine!
During what stage of engine operation does the piston move upward in the cylinder and force the burned?
During the power stroke stage of engine operation, the piston moves upward in the cylinder to force the burned air-fuel mixture out of the combustion chamber. This upward movement generates mechanical energy that is transferred to the crankshaft to produce the engine's power.
