Tdc On Compression Stroke FAQ

What occurs during the compression stroke?

Mechanical Operation. During the compression stroke, the electrical contact is kept opened. When the volume is the smallest, and the pressure the highest, the contact is closed and current flows through the completed circuit. The switch is then quickly opened, producing a spark which ignites the mixture .

What is the top dead centre compression stroke?

The four separate strokes are termed: Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). ... Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. ... Combustion: Also known as power or ignition. ... Exhaust: Also known as outlet. ...

What is the definition of compression stroke?

The compression stroke is the stroke in an engine in which the air or air/ fuel mixture is compressed before ignition . The intake valve closes and the piston starts up on the compression stroke . During the compression stroke, the piston moves up the cylinder, squeezing the fuel-air mix.

What is the compression stroke of engine?

The compression stroke is the second of four stages in a four-stroke engine. In this stage, the fuel/air mixture (or air alone, in the case of a direct injection engine) is compressed to the top of the cylinder by the piston. This is the result of the piston moving upwards, reducing the volume of the chamber.
