Motorcycle engine system

Motorcycles are formed with several components. Motorcycle components consist of several series. The series becomes a well-structured entity, so that if one is damaged it will affect the other part.This may be likened to the limbs of human beings, for example when our feet trip over stones and feel pain, surely the other members of the body feel the same.

Save the word, the motorcycle is composed of several components into a single unit. The components on the motorcycle can basically be classified into:
1. Machine system
2. Electrical and frame systems

The discussion on this article is about engine systems for motorcycles. The engine includes components for power sources that can drive the motorcycle. What needs to be observed on the motorcycle engine that is part of the source of power, transmission circuit and engine power capability to drive the rear wheels.The motorcycle engine system itself is divided into
1. Fuel system
2. Lubrication system
3. Exhaust system
4. Cooling system

From the motorcycle engine system parts can then be described as follows:
1. Fuel systemThe use of fuel for motorcycles can use premium, pertalite, or pertamax.
The beginning of the fuel system for motorcycles is to use the carburetor system. Carburetor is a tool used to mix fuel and air. Most motorcycles use a carburetor, this is because the carburetor is felt cheaper and lighter.In its development, in the world of fuel system began to be introduced a new system of injection, the motorcycle used in 2006. The use of fuel injection system is more easily integrated with other systems, and to obtain efficiency in the use of fuel.

2. Lubrication system
Good oil plays a role in motorcycle lubrication system for engine performance. Regular oil change and proper oil selection, can help extend the life of motorcycle usage. SAE (The Society of Automotive Engineers) is generally used to measure oil viscosity. Often motorcycle running, then make the viscosity of oil decreases. This makes the lubrication decrease as well. Examples of SAE in engine oil include:
- Ultratec matic oil: SAE 10w-30
- Ultratec oil: SAE 20w-50
- Oli yamalube matic: SAE 20w-40
- Oli yamalube sport: SAE 10w-40

Good oil for minimal motorcycle lubrication must meet the following requirements:
    Easily transfers heat generated from engine performance.
    Not easy to yawn.
    Has a low freezing point.
    Good stickiness.
    Have a high flash point.

The benefits of regular oil consumption include the following:
a. To withstand heat on a motorcycle engine.
b. Making pistons and piston rings works well, so the machine becomes durable.
c. As anti corrosion.
d. Can be used to clean the dirt on the machine
e. Refine the sound of engine performance
f. Reduces friction on the machine.

Motorcycle lubrication system there are 2 kinds of lubrication for 4 stroke motor and 2 stroke motor. Motorcycle 4 not only use one type of engine oil without the use of side oil. Engine oil is poured into one container. The oil contained in the container, will lubricate every part of the motorcycle engine cylinder. Some mention it with the term sprinkling system. Can be seen from the oil ring function that has been installed on the piston. The oil ring will clean and lubricate.While the motor 2 no, lubrication method there are 2 ways that is in mixed and put in a separate place. For mixed methods, mean side oil is used in conjunction with the fuel. And using a separate place means side oil is accommodated in a separate container.

3. Exhaust system
In this exhaust system the role of exhaust should also be known. The exhaust has several important parts, and the exhaust should also have an emissions standard on the threshold of reasonableness. Here the exhaust can muffle the sound generated from the engine turnaround process. The function of exhaust system on motorcycles are:
    Can exhaust combustion gas from engine performance.
    Can muffle the sound from the burning.
    Able to provide improvements to engine power.

4. Cooling system
The world of machinery is always evolving. Given the high efficiency in the development of the machine, it is also necessary to consider the economic factors, durability, safety of the rider and friendly to the environment. The high temperature conditions in the engine resulting from the ongoing combustion process in the absence of maintenance, this may cause.
