Engine cylinder volume | Auto Repair Answers

In order to provide better engine performance, you need to know what a engine cylinder volume, the volume of the compression chamber, the total volume of the cylinder, compression, displacement and speed of crankshaft. Cylinder volume – the volume between the dead spots. It is filled with a combustible mixture in the intake stroke, ie, When the piston moves from top to bottom dead center. When the piston reaches top dead center above it remains a small space, which is called the compression chamber or combustion. If the volume of the combustion chamber to lay down with a wor

king volume of the cylinder, we obtain the total volume of the cylinder.
All these quantities are measured in cubic centimeters. When dividing the total volume of the cylinder on the volume of the combustion chamber in a value, called the compression ratio.
Compression ratio shows how many times the compressed fuel mixture in the cylinder. The higher the compression ratio, the greater the pressure on the piston during the combustion of the mixture, and thus more horsepower. Increase the compression ratio is very favorable – from the same portion of fuel can be more useful work.

G.K. Kannan However, excessive increase in the degree of compression self-ignition occurs the working mixture and the mixture is burned at high speed – is the detonation of fuel. Detonation – this is unacceptable rapid combustion of working fluid, causing unstable engine operation. The engine comes with a sharp knock, power it down, out of the muffler out black smoke. The designers are seeking ways to deal with the detonation of the fuel and gradually increase the degree of compression. Depending on the degree of compression is used a certain grade of fuel.

Increase the power of the engine also allows an increase in the number of revolutions per minute the crankshaft. However, in this way, there are difficulties: mainly the lack of time on the inlet fuel-air mixture in the cylinder and the exhaust, the occurrence of excessively high rate of movement of parts of the crank and gas distributing mechanisms and their high wear.

Overcoming these obstacles, the designers sought to increase the speed to 1000 5000 in a minute. If the multi-cylinder engine, the swept volume summarize and receive volume, called displacement engine.

Volume in cubic centimeters counted and then converted to liters. The increase in engine displacement is accompanied by increasing its volume. Volume determines the class of vehicle.
