Automobiles are one of the most important things in our daily life. We all use the basic terms used in automation systems. but sometimes we do not recognize the basic terms. Most of the names are familiar for you, but in short description we try to put the main function and proper introduction. In this post, you are reading the first ten terms.
1. IC engine: The internal combustion engine is a type of engine in which the fuel is mixed with other media like air and burned in the combustion chamber. In the internal combustion engine high- temperature and high-pressure gasses are produced by combustion which provides power to some module of the engine.
2. SI engine: The spark ignition engine is a type of internal combustion engine. Spark ignition requires a spark plug for the ignition of low compression ratio of fuel. The maximum efficiency of this type of engine is comparatively low. This engine works on Otto cycle.
3. CI engine: The compression ignition engine is the second type of internal combustion engine. Combustion engine requires a high compression ratio consequently self-ignition takes place in high temperature. The engine works on Diesel Cycle. The efficiency of this type of engine is high.
4.CC/ cubic capacity: Engine pistons move Top dead center to bottom dead center, this is known as swept volume. The single movement of the piston from top dead center to bottom dead center is referred to as cubic centimeter.
5. Ground clearance: The space between the lowest part of a vehicles frame and the ground is known as the ground clearance of the vehicle. The ground clearance is somehow related to the vehicle's center of mass. Increasing the center of mass decreases the handling characteristics of the vehicle. Some automobiles have lower ground clearance that improves the center of gravity of the vehicle (this also improves car handling).
6. SUV: the word SUV stands for Sport utility vehicle. These vehicles are small size trucks which are used as family vehicles. The name of SUV is not used everywhere; they are popular by the brand name to describe the vehicle like "Jeep". Mainly the Sport utility vehicles are mid-size passenger's vehicles. SUVs are popular in the United States and India that encourage automakers to improve design.
7. MUV: These are larger vehicles which can tackle a wide range of applications. They typically allow easy conversion between multiple combinations of passenger and luggage capacity. The main purpose of the vehicle is to work more effectively and carry more load compared to general vehicles.
8. Fuel Injector: The injector of fuel maintains an injection amount of fuel in each cycle. The fuel injector pump can control timing of injections. The high temperature of air at the end of the stroke is sufficient to ignite the fuel. The main function of the fuel pump is to atomize the fuel in very fine particles and correct the quality of fuel to be injected as per the load of the engine and increase the automation speed.
9. Auto transmission (auto gear): Auto transmission means the automatic shifting the gear ratios when the automobiles move. Hydraulic automation is used by most of the heavy vehicles. The automatic transmission helps drivers to concentrate less on shifting arrangements. In comparison between manual and auto transmission the fuel efficiency is affected.
10. Camshaft: The camshaft is essential for operating valves in internal combustion engines. These valves regulate the intake and exhaust of air-fuel mixture and gases. They open and close at precise times during the piston stroke. The crankshaft is crucial for converting linear motion into rotational motion in the engine.
