Your Vehicle Catalytic Converter. "Indomie"
About a vehicle's catalytic converter "indomie"
A catalytic converter is a large metal box, bolted to the underside of your car, that has two pipes coming out of it. One of them (the converter's "input") is connected to the engine and brings in hot, polluted fumes from the engine's cylinders (where the fuel burns and produces power). The second pipe (the converter's "output") is connected to the tailpipe (exhaust). As the gases from the engine fumes blow over the catalyst, chemical reactions take place on its surface, breaking apart the pollutant gases and converting them into other gases that are safe enough to blow harmlessly out into the air.
WHY IS THE CATALYTIC CONVERTER EXPENSIVE
The catalytic converter is constantly being targeted by thieves is because the catalyst is made up of a mix of precious metals.
Platinum is the most active catalyst and is widely used in the manufacture of the catalytic converter including Palladium and Rhodium. Copper, Cerium, Manganese and Nickel are also used.
These are very expensive precious metals and are highly sought after around the world. The average price for the content of a catalytic converter in the metal black market ranges from 2000 naira to 10,000 naira. Replacing them could cost between 20,000 naira to 150,000 naira depending on your car model.
SYMPTOMS OF A FAILING CATALYTIC CONVERTER
1. Misfiring.
2. Reduced Performance.
3. Low Fuel Economy.
4. Low Performance of the Exhaust System
5. Increase emission
V6 or Four?
V6 or Four-Cylinder Engine?
An engine cylinder is where the combustion process occurs. Inside each cylinder is a piston, which moves up and down inside the cylinder (or side to side, as we will learn). Each cylinder is connected to a crankshaft. The crankshaft delivers the energy created by the combustion process to the transmission and, ultimately, to the wheels that drive the vehicle. Generally speaking, the more cylinders an engine has, the more horsepower and torque an engine makes
Engine cylinders are typically arranged in a vertical orientation, lined up one after another from the front to the rear of the engine, or in a V-shaped orientation with an equal number of cylinders on each side. When engine cylinders are vertically oriented, the engine has an "inline" configuration, which is used in conjunction with 4, 5, or 6 cylinders. When engine cylinders are V-oriented, the engine has a "V" configuration, which is used in conjunction with 6 or more cylinders. If an engine is mounted transversely, which is common for front-wheel-drive vehicles, the cylinders and crankshaft are oriented from side-to-side rather than front-to-back.
Inline engines (I) are taller and narrower, and when they are mounted transversely, allow designers to create a vehicle with a smaller front end. V-type engines (V) sit lower with an improved center of gravity, and this design is more space-efficient with a greater numbers of cylinders. Horizontally opposed engines (H) sit very low and wide, producing a low center of gravity and improved handling.
A 6-cylinder engine features six pistons and produces a theoretical 50% more power than the same 4-cylinder engine. While a 4-cylinder engine might hesitate when you press on the gas, a 6-cylinder will tend to be more responsive, with greater get-up-and-go.
The 4-cylinder engine is standard in smaller cars, as the relatively light weight of the vehicle makes it an economical choice with plenty of power for average motoring needs.
The smaller engine will be less expensive and should get slightly better gas mileage, just on gas. And the disadvantage of a 4 cylinder is a lack of power that might factor in more for commuters and travelers. For hilly or mountainous areas, the 6-cylinder engine would likely be a better choice.
