Cycle Engine Diesel Four Steps<\/strong>
\nThe working process of the motor fuel cycle four steps can be described as follows:
\n1. Step Suction<\/strong>
\nIn this step the piston moves from top dead point to the point \u00a0 dies down. Suction valve open so due to vacuum \u00a0 the case of expansion of the volume in the combustion chamber, the air from the outside \u00a0 can get into the combustion chamber through the suction valve \u00a0 open. In combustion engine equipped with a turbocharger \u00a0 the air entering the combustion chamber will be more \u00a0 due to the encouragement of the press compressor wheel \u00a0 padaturbocharger.<\/p>\n

2. Step Compression<\/strong>
\nAfter the piston reaches bottom dead point, the direction of the piston will \u00a0 turned toward the back to the top dead point, it’s just that in step \u00a0 no valves are open. As a result of \u00a0 shrinking the volume of the combustion chamber, the air that is in \u00a0 combustion chamber becomes compressed. With a compression ratio \u00a0 ranging from 19: 1 to 23: 1, the air pengkompresian \u00a0 in the combustion chamber will produce compression heat (heat \u00a0 compression) is high (approximately about 1,000 \u00a0 oF).<\/p>\n

A few degrees before the piston reaches top dead point material \u00a0 The diesel fuel-injected through nozle into the combustion chamber, \u00a0 of the injection should use a high pressure \u00a0 so that diesel fuel is sprayed into the combustion chamber changed \u00a0 into granules and solar fluid very smooth like a fog. \u00a0 At the time of the diesel spray mixture of diesel and \u00a0 the air in the combustion chamber began to burn from the heat affected \u00a0 heat generated by compression.<\/p>\n

3. Step Power<\/strong>
\nThe process of burning a mixture of diesel fuel and air continues \u00a0 until the piston reaches top dead point and then back \u00a0 change direction back toward the bottom dead point. Some degree (+ \u00a0 10o) after passing through the point of death on the arson \u00a0 has been perfect so that the resulting explosion pressure \u00a0 forcing the expansion piston to continue moving towards the point of death \u00a0 below.<\/p>\n

4. Step Disposal<\/strong>
\nAfter the blast of heat energy in the power step has been transformed into mechanical energy, the rest of the combustion process that there should be discarded. This process occurs when the piston moves from the bottom dead point to the top dead point to the condition of the exhaust valve opens. Waste products of combustion gases driven off by the piston through the exhaust valve.<\/p>\n

Furthermore, through mufler the gas will be released into the atmosphere. Except for diesel combustion engine equipped with a turbocharger then before entering into the gas mufler still be used to rotate sudu- turbine blades on the turbine wheel.<\/p>\n

Similarly, this cycle occurs continuously on diesel motor fuel. Illustration of a diesel four-step process work can be seen in the image below. Image sequence from left to right show the condition: the end of the suction step, the end of the compression stroke, the initial step initial step power and exhaust.<\/p><\/div>\n
