Advantages and Disadvantages Technology VTEC

His time I will discuss about the Principle of Work Motor Gasoline 4 Steps. Step is any movement of the piston from the top of the cylinder or TDC (top dead point) to TMB (bottom dead point) or opposite from the TMB to the TMA. One step equals half the piston crankshaft rotation. Motor 4 stroke, for each cycle consists of four steps is a step of suction, compression, and exhaust business. Crankshaft or the crankshaft rotates twice selamapiston full round is completed the 4 steps. Here are pictures and descriptions principle works as follows:

a. Intake Stroke

The first step is the exploitation of which the fuel from the carburetor into the cylinder bore, at this step the piston moves from TDC and TMB sticks at the same time intake valve (intake valve) opens and the exhaust valve (exhaust valve) closed the meeting. At this suction step go mist of fuel and air mixture through the inlet or intake valve into the cylinder bore. After the fuel suction end of which the position of the piston is at TMB, the valve closes and the entry of terperangkaplah mist of fuel and air mixture inside the cylinder.

b. Compression Stroke

The second step is the compression stroke where the piston moves from the TMB to the TMA. In this step the second valve in a state closed the meeting so that the resulting compression of the engine is good. Large or small power generated by a machine good or bad depending on the compression results, as well as many, or at least the mixture of fuel and air is sucked in the first step. Shortly before the piston reaches TDC at the end of the compression stroke, spark plugs fire, causing combustion and high-pressure hot gas is formed.

c. Power Stroke

The third step is the step labor or business, in which the piston moves from TDC to the TMB, referred to the work steps for power generated at this step in order to run the vehicle. At this step the second hold still tetep valve shut and just before the piston reaches TMB, dump valve starts to open.

d. Exhaust Stroke

The fourth step is a step in waste, where the piston moves from TDC and TMB to the dump valve open, whereas the entry valve closes tightly. The movement of the piston toward the TMA TMB aims to encourage the rest of the combustion gases toward the exhaust. and return to the initial steps onward. Thanks for reading, hopefully useful for all your friends.
