Why initial pickup is better in two stroke engine as compare to four stroke engine?
The two stroke has more initial pickup because combustion happens every time the piston is at or near the top dead center. In the four stroke, combustion happens every other time the piston is at or near top dead center. <><><><><> Since the combustion cycle occurs every rotation, instead of every other rotation, there is twice as much torque available to the engine output.
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 intake stroke in a four stroke cycle?
the air mixture i.e air and the fuel mixture entering the clyinder during the piston moving from top dead center to bottom dead center this is known as intake stroke
What position is the pistons when at top dead center?
At top dead center (TDC), the piston is at its highest point in the cylinder, positioned at the very top of its stroke. This occurs at the end of the compression stroke for the intake or compression cycle, and at the end of the power stroke for the exhaust cycle in a four-stroke engine. At this position, the piston is effectively at the zero-degree mark in relation to the crankshaft. It is crucial for timing events in the engine's operation, such as valve opening and closing.
Advantages of two stroke engine over a four stroke engine?
Explain the advantages of four-stroke engine over two-stroke 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!
Which engine was invented first.Two stroke engine or four stroke?
two stroke
Why you prefer four stroke engine over two stroke engine?
Four stroke engines are quieter than two strokes, but have less power.
Compare the two stroke and four stroke engine in powe output and thermal efficiency?
compare the two stroke and four stroke engine in power output and thermal efficiency?
What is the second stroke called?
In a four-stroke engine its called the compression stroke
What statement correctly describes a four-stroke engine?
The four-stroke engine produces 1 power stroke for every 720 degrees of crankshaft rotation.
What are the four strokes to a four stroke engine?
The four strokes of a four-stroke engine are the intake, compression, power, and exhaust strokes. During the intake stroke, the engine draws in air and fuel. The compression stroke then compresses this mixture, followed by the power stroke, where the spark plug ignites the mixture, generating power. Finally, in the exhaust stroke, the engine expels the burnt gases from the combustion process.
