The Motor Cylinder

A 4 cylinder motor was not very popular before as cars equipped with engines of this type were considered weak and unreliable on acceleration. Japanese automobile manufacturers, however, proved that these engines can be efficient as they were not far behind when it comes to performance compared to cars with engines having more cylinders. They have been a popular choice for cars made in Japan. Let us try to enumerate the benefits of a four cylinder engine.

Most engines that sport four cylinders have the in-line design, which means that the cylinders are arranged in one line; however, there are still designs which have tried to sort the cylinders in a V-shape.

One benefit of the 4 cylinder motor is that it takes up less space in the car. This naturally means more space for other things like the other mechanisms that make the car work and other accessories of the car. The owner gets the most benefit as it means more space in the car for passengers where it matters most.

From a manufacturer’s standpoint, this type of engine is easier to craft as there are less parts to create and connect to make the vehicle work. It takes less investment in money and time to manufacture.

From a marketing perspective, these types of cars are easier to sell as they cost less compared to other vehicle types. Smaller cars also cost less insurance compared to bigger cars.

From a maintenance point of view, the 4 cylinder motor requires less maintenance and less money if work is necessary on the cylinders. For example, if a cylinder sleeve is mandated on the cylinders, then you only have four to install. This will take less time to accomplish compared to an engine with six or eight cylinders.

Having fewer cylinders equate to needing less fuel to function. This means fewer emissions thus making this engine type more environment-friendly. With environment conservation a major aspect of today’s living, this is a major selling point for this engine type.

Less fuel naturally means less strain on the pocket as the car owner gets more mileage per liter of fuel consumed. If two cars with engines having different numbers of cylinders were given the same amount of fuel and were made to run under the same speed, the four-cylinder motor will cover the greater distance.

With the advancement of automotive technology today, a motor with four cylinders is now able to match the power output of engines having more cylinders. So if performance is reviewed, for example if cars with different cylinder types were tested on the road, it may even be difficult to determine which car had the four cylinders and which one had more because there is only a negligible difference with the car’s acceleration and power.

Cost, performance and reliability are things to consider when purchasing a new car. Automobiles having engines with four cylinders have always been a popular choice for many because it gives them good value for their money.

For the car enthusiast, it is not only the loyalty to a manufacturer or the beauty of the car that is considered nowadays in the purchase of a vehicle, but also what is under the hood. Actually, what is underneath the hood is more important as it is what determines the performance of the car on the road.

Many people inspect the engine and the other mechanisms that make the car work before deciding on a purchase. Most have posed the question as to how many motor cylinders are the best to have in an engine. The answers you may get vary. It all depends on your purpose, desire and budget. Let us take a look on the different size motors and see what we can discover.

Car manufacturers have various designs for chassis and engines. There are conventions in place, though, for engine designs. For instance, one of these is the arrangement of cylinders. Most use the V-type engine but others still utilize the in-line type. The V-type, as the name implies, has the cylinders sorted in the form of the letter V. The in-line type has the cylinders arranged in one line.

The other convention on engine design is the number of cylinders on the engine. Different size motors offer different numbers of cylinders on the engine. Common designs are the four, six, and the eight-cylinder engine.

The four-cylinder engine usually has the in-line structure. The most obvious advantage of the four cylinder type is that it is compact. It takes less space thus making more room for the other parts of the vehicle. This is usually used for small cars. Passengers have more space on a car which uses this design. Since it only has four cylinders, it also uses less fuel. This saves money for the car owner. It also means fewer emissions and is considered by some to be more environment-friendly. Having a smaller engine also means less money on the price tag.

The six cylinder engine typically uses the V-shape design. Having more cylinders, it naturally offers more power than the previous type. More power means greater acceleration and a smoother ride on long trips. This is the choice of most car buyers who want to get a car that is a great companion on the road.

The eight-cylinder and twelve-cylinder designs are often seen on sports and luxury cars. These designs use the V-shape structure. Having more cylinders give these engines great power on acceleration and sustained speeds on a trip. Needing more fuel to run, cars with these engine types are not a popular buy among the populace because of their high price tag.

Different size motors provide cars equipped with these engines different levels of performance. It is up to the buyer to decide which is best suited for him. The comparison lies mostly between the four and the six-cylinder engine. The criteria often used to distinguish which one to buy are the power of the engine and the price of the car.

It is much easier to learn how to drive a car than it is to comprehend how gasoline or diesel purchased from a gas station can make your car work. Although a bit of information is given about how vehicles work in a driving course, more often than not, this is taken for granted as the important thing in these courses is on driving.

Although mechanisms involved have evolved through the years and may even seem too complicated to be understood by the layman, we will try to simplify the seemingly complex process of how engines work with a focus on motor cylinder.

All engines use a piston to provide power to some moving mechanism, usually a crankshaft for motor vehicles. A cylinder is used to house the piston. This is where combustion takes place. The familiar four-stroke cycle of intake, compression, power and exhaust occurs here. We will try to explain this cycle, taking for example a gasoline engine.

On the first cycle referred to as Intake, air is drawn into the cylinder. On the next cycle called Compression, this air and fuel combination is compressed into the cylinder. On the third cycle known as power, a spark plug ignites this mixture. On the final cycle named Exhaust, the products of combustion are taken out of the cylinder. The cycle then repeats itself. Take note that this cycle happens very quickly, within a matter of seconds.

The four-stroke cycle is what makes the vehicle run. It all happens in a motor cylinder. So now you can just imagine how important this part is on an engine. Since it takes the brunt of the combustion, naturally, this part should be made of sturdy metal. And it is so.

Most engines are made of cast aluminum or cast iron and the cylinders are of the same metal. Some designs, though, line the cylinder with a stronger metal, usually an alloy, or just coat it with a wear-resistant coating.

There is a process called ‘cylinder sleeving’ which is used to fix cylinder walls after being worn from use. Usually made of iron alloys, the sleeves, as they are called, are inserted and pressed into place in the cylinder. This is one of the maintenance procedures given to a motor cylinder.

Since combustion generates heat, the design of an engine considers highly how the cylinders are cooled. Some are air-cooled, others water-cooled, and still others are coolant-cooled. A coolant is a liquid chemical specially formulated to provide cooling to engines.

The two most common arrangements for cylinders are the in-line and V-shape. In the former, the cylinders are placed in one line only and in the latter, they are placed on opposite sides of the engine forming a letter V.

Besides the arrangement, the number of cylinders in an engine also varies depending on the vehicle’s design. For a car, the most compact is the four-cylinder engine. Other manufacturers have six and eight-cylinder engines. Formula One race cars even have up to 12 cylinders.
