PRINCIPLES OF MOTOR GASOLINE 4 TAK

Work is the overall process of successive steps for the occurrence of a work cycle of the motor. The working process occurs sequentially and repeatedly. Motorcycle piston moves back and forth from the top dead point (TDC) to bottom dead center (BDC) and from bottom dead center (BDC) to top dead center (TDC) on the next step

PRINCIPLES OF MOTOR FUEL FOUR STEPS

Suction step

In this step, a mixture of fuel and gasoline in the suction into the suction opening silinder.Katup while the exhaust valve is closed. Time the piston moves from top dead center (TDC) to bottom dead center (BDC), causing the cylinder into the vacuum chamber and causing an influx of air and fuel mixture into the cylinder due to the outside air pressure. (Source: New Step 1, pp. 3-4)

Step Compression

In this step, a mixture of air and fuel is compressed. Suction valve and the exhaust valve is closed. Time piston up from bottom dead center (BDC) to top dead center (TDC), which is inhaled mixture was compressed. As a result, the pressure and the temperature will rise, so will 
flammable. When this happens a spark from the spark plug. Crankshaft rotates one time when the piston reaches top dead titk (TMA). (Source: New Step 1, page 3 -4) 

Step Enterprises

In this step, the engine produces power to drive the vehicle. When the piston reaches top dead center (TDC) during the compression stroke, spark plugs provide the spark jumps the mixture has been compressed. With the burning, the strength of the high pressure combustion gases push the piston down. This effort is a power machine. 

Discard step

In this step, the gas is burned, will be thrown into the outer cylinder. Exhaust valve open while the suction valves piston tertutup.Waktu bergarak from bottom dead center (BDC) to top dead center (TDC), a former gas pushed out of the cylinder. At the end of the current step and the initial step waste a second suction valve will open slightly (valve overlap) which serves as a rinsing step (a mixture of air and fuel new push residual combustion gas). When the piston reaches TDC, will start moving again in preparation for the next step, the step suction. Crankshaft has done 2 full rounds in a single cycle consists of four steps, ie, 1 step suction, compression step 1, step 1 business, 1 step waste which is the basis of the work on the four-stroke engine.

In the four-step motors, the motors work completed in four piston step. The first step is the piston moves from TDC to BDC, called the charging step. The second step is the piston moves from BDC to TDC is called the compression stroke. The third step piston moves from TDC to BDC venture called steps. At step in efforts to pass the combustion process fuel (mixture of air and fuel) in the engine cylinder / combustion chamber that produces power that drives the piston dariTMA keTMB. The fourth step is the piston moves from BDC to TDC called dumping measures. Combustion gases exit the cylinder piston is driven by a motor. So the motor work a four-step process to produce a step mptor business (which produces power) required four steps piston. Four step piston means equal to twice the crankshaft rotation.

In the two-step process of working the motor bike to get a one-time effort only required step dau times the pistons. Two motorcycles the simplest steps, entrance or inlet and exhaust port located opposite each other which is located on the underside of the engine cylinder walls. Process works is as follows. Piston is TMB, these two holes (incoming and exhaust) at the same open then air and fuel mixture is inserted into the cylinder through the inlet. Movement of the piston from BDC to TDC, then masukakan hole closed and closed the hole there buang.maka compression stroke. At the end of the compression stroke fuel gas combustion occurs. With the burning of the fuel gas combustion generated power that drives the piston down from TDC to BDC.Step last attempt to pass exhaust gas so the former open pit waste. After it opened to the inlet resulting in new gas intake while encouraging the former gas push out through the exhaust port. Thus the two-step process on the motor bike one time step to generate business / combustion gas in the cylinder, the piston only takes two steps.seen from the crank shaft rotation required one crankshaft rotation.
