A majority of vehicles on the road today are equipped with a diesel or gasoline engines in this position only in the mechanical work, albeit temporary. Motor control on a large majority of modern cars is done either by using a synthetic rubber band or a steel timing chain.
The importance of motor control is not easy to explain, but we give it a shot to make it easy to understand. With a four-cylinder SOHC engine as an example, there are two important meetings to run the engine itself, ie the crankshaft and the other is the camshaft. The crankshaft has a unique purpose, run the piston up and down in the cylinder bores in the four-stroke motor cycles. The camshaft is responsible for opening and closing the valves inside the head attached at intervals, either remove air in the cylinder or exhaust after the combustion process.
When these two components are not properly synchronized to the vehicle, by design, can not be executed. If the number one engine cylinder in the top dead center (the highest point of the journey) is a mark on the crankshaft pulley or gear, that the date should reflect the character built into the engine. If a vehicle is at top dead center on number one cylinder on the head for that cylinder valves in a fully closed position so that both the compression and combustion stroke of the engine, the cylinder. This timing is usually easier with the use of another mark on the camshaft, which then align with a different timing mark on the engine itself to ensure everything is in good agreement.
If the timing is as little as one tooth of the vehicle to be able to fire and to implement, but it will not work as intended, and many cars will not even attempt to run if the timing is not perfect. A qualified technician should be able to view the date marked to identify the components and ensure that the machine is good before you try to fire timed.
Some vehicles are than classified what is known as an interference engine. If any of these engines may be the timing is missed, even by as little as one tooth, the valves to open at the wrong time, so they really connect with the pistons as they are at the forefront of their journey. If this happens, it is customary to bend them, require the removal of the valves to replace the cylinder head and the valve would, before the engine can be fired again. This is not an easy process for many modern cars.
It is important to ensure that the time by an experienced technician is to protect your investment. While it seemed to the guides who accompany them to buy through the process of timing engine. The risk of errors outweigh the savings that you can by making the process itself, so it is best left to the professionals, to ensure that the job right the first time is done.
