Automotive
The engine is producing power. Components are arranged in this work very much. Among the most vital is the cylinder block (engine block), cylinder head (cylinder head), pistons, piston rings, connecting rod (piston handlebar), and the crankshaft (crankshaft). In addition, there is also a valve mechanism consisting of a camshaft (nok shaft), valve lifter, pushrod, timing belt (timing chain) and valve (valve). But, do not forget one thing that also helped drive the machine. Namely, fuel.
Whether or not the employment components in the machine is very dependent on the quality and quantity of oil and water radiators. In addition, it is important also consider setting-adjustment (tune-up). Although the condition of the engine components depending on the oil, radiator water and tune-ups, in terms of maintenance and inspection of the car, it does not mean not important to know how to work the engine to produce power.
In principle, when the engine starts the starter, will rotate the crankshaft connecting rod moves. Because the connecting rod moves, pistons and piston rings part moves up and down. At the time the crankshaft rotates, the timing belt will deliver the movement of the crankshaft to the shaft so that the nok nok shaft will also rotate. Nok shaft rotation make the valve open and closed.
The cars are now generally use a 4 stroke engine. That means, for the discharge power, the engine 4 stroke piston to 4 steps. Four steps are suction, compression, effort (power) and exhaust.
In the suction step, the piston moves from top dead point (TDC) to bottom dead point (TMB). At that time, the suction valve opens and the exhaust valve closes. When the suction valve opens, fuel will be sucked into the combustion chamber. At the same time, the crank shaft 90 moves the first degree.
In the compression stage, the piston moves from the TMA TMB. In this step, the valve is closed. Because closed, the piston rises. The rise of the piston to make the engine narrower. This resulted in a narrowing of the temperature and fuel pressure go up. Here, the crank shaft 90 moves the second degree.
At the time the crankshaft position 5 degrees before TDC, a spark from the spark plug came out. Sparks that burn fuel in the combustion chamber. Burning produces pressure that will push the piston so that it moves from TDC to the TMB. At the same time, both valves closed. This is called a step effort (power). Here, the crank shaft 90 moves to the third degree.
The next step is wasted. At this time the piston moves from the TMA TMB. The exhaust valve is open while the suction valve is closed. The piston movement resulting from the combustion exhaust gas driven towards the exhaust. Fourth piston moves 90 degrees.
These steps will occur repeatedly in accordance with the rotation of the crankshaft. With the rotary engine was producing power. This power will be used to drive the wheels. In addition to the wheels, power is also sent to the functional components for the survival of the machine. For example, the ignition system, fuel system, charging, and comfort systems such as air conditioning, power steering.
The successor to the Wheel
Power from the engine components were delivered by a medium called the successor. To drive the wheels for example, there is some kind of successor to power. Among the front-wheel drive and rear-wheel drive. And there are also four-wheel drive or all at once commonly known 4WD (wheel drive).
Rear-wheel drive models, for example, the device is the successor to the clutch, transmission, propeller shaft (coupling), axle, axles (axle shaft), wheel bearings and the wheels themselves. Front-wheel drive is also aided by the use of devices that, unless the propeller shaft. There is an additional device for 4WD called the transfer. In addition, the coupling device also features 4WD front, rear, front-rear axle, and front and rear axles.
This clutch has a very important role in deciding and connect power from the engine to the transmission. To support its work, in the clutch there is a canvas clutch, coverclutch (sun), release bearing (ball bearing). If the clutch is not functioning properly, then the power generated to drive the vehicle is reduced. In fact, the vehicle can not walk. Can also cause damage to the clutch to shift gear transmission difficulties. Some of the causes of the clutch is not working properly, either because of age or it could be due to the use of less exactly the way you drive.
Therefore, the coupling should also be checked frequently. There are conventional ways to check to clutch. Turn on the machine, then enter your vehicle into gear transmission gear 2. After it stepped on the gas pedal and brake pedal simultaneously. If your engine off means the clutch is still thick canvas. But if your engine still alive means that means the clutch is clutch slip and canvas needs to be replaced.
What is also important to examine is the transmission. This serves to set the transmission speed of the vehicle or the moment. It sends power to the axle via the coupling. If he is not functioning properly, or may be going wrong usage, your engine could die, or maybe pull heavy and limp.
The easiest signs to see whether or not your car transmission work is to do a gearshift. If the displacement teeth easily, does not sound strange noises when the car skids, it means either. In addition to driving, the transmission of health also depends on the quality and quantity of oil.
In the rear-wheel drive and 4WD model, there are between the transmission and axle coupling work. Its main function for the stable to swing the car due to road surface changes. Due to different road surfaces, the coupling is equipped with a universal joint. These tools served to adjust the angle changes to the road surface. This will affect your driving comfort. If the universal joint is jammed, then the continuation power will not be maximized. In addition, the vehicle body will vibrate while sliding. If your car body vibration and excessive feel different, you should replace the universal joint or coupling balance.
So also with the axle. Its function is very important. It serves to change rotation of the coupling to 90 degrees and zoom in moments. In addition, it also serves to distinguish the left and right wheel when turning.
Symptoms of damage to the axle can be detected by a buzzing sound coming out of the axle. For lubricating oils that need to be checked and re sets the teeth on the axle intersection.
Components of the power transfer is not less important is the axle shaft and bearing. The second component serves to continue the effort and softens the drive wheels spin. To maximize component life, adjust to the use of the vehicle load limits have been determined. And to check the wheel bearings can be done by listening to sounds or by wiggling its tires, both front and rear.
The successor to the Comfort Components and Survival Machines
In addition to drive the wheels, engine power is also used to drive the components associated with the survival of the machine and rider comfort. These components are Timing Belt (for certain types), Van alternator belt, belt Van Air Conditioning (AC) and Van power steering belt.
Timing belt went round play of the crankshaft to the shaft nok. Its own rooftop duty drive shaft valves, rotating distributor (Delco) in the ignition system. Nok shaft also serves to drive a petrol pump in the fuel system (in the conventional type).
Because the timing belt life and death plays a role against the machine, it needs periodic maintenance. Each car has different specifications. Usually for passenger cars based on the timing belt replacement mileage of about 50,000 s / d 60,000 km are shown on the odometer.
When you are up to that number, you should replace the timing belt. Can not be replaced if broken. Therefore, the timing belt is made of special rubber. And when broken, the engine can strike even cause the valves and cylinder head (cylinder head) can be bent or deformed. When that happens, the cost of repairs will be much more expensive.
Van Alternator belt serves to drive the dynamo ampere (alternator) to the charging system, and to drive the water pump (water pump) on the cooling system. When the van was broken belt, can result in electric cars do not work. Even the engine breaking down. Also, it can also result in vehicles having engine overheating (overheating).
Van belt Air Conditioning (AC) function to move the AC compressor. If the van is loose or broken belt, vehicle air conditioning work will be disrupted. This means that the rider failed to get the comfort of air conditioning.
While Van Power steering belt serves to drive the power steering pump. When the van was broken belt, steer the car to be heavy, especially on parking conditions.
Well, because the van belt has a very important role, then there are some things to check on the condition of this van belt. Examination can be done by looking at the van belt. Check the possibility of rubber on the bottom of a separate core, the core edge and core separate van belt. Or, it may also occur cracks, separation separation van belt ribs, ribs, ribs torn or cracked ribs on the ridge of van belt. Try also tapped van belt. In this way, you can test the belt tension and tightness van.
