With the arrival of 2020, you surely have many purposes in mind that you want to fulfill, such as having a better job, adopting a pet or acquiring a new car and it is with that last goal that we want to help you. If you are analysing what kind of car you should buy, then you cannot miss this guide where we put diesel cars vs gasoline face to face, compare their similarities and differences and tell you which one is best for your needs.

Both diesel and gasoline are internal combustion engines. This means that the fuel mixes with the air when it enters the engine and is compressed internally, inside the cylinders. At some point, the fuel ignites (explodes), pushes a piston down and rotates the crankshaft, which is connected to the vehicle’s transmission and, finally, spins the wheels. The piston then moves up the cylinder, pushing the burnt gases out of the engine through the exhaust pipe. This cycle is repeated several times per second.

The more cylinders an engine has, it will tend to run more smoothly, and the greater its power will also be. However, it will also be more complex. The way the cylinders are configured influences performance, vibration and other factors. And this is true for both gasoline and diesel engines.

Where both engines diverge is how the fuel is ignited inside the engine. In a gasoline engine, air and fuel are compressed and, at a critical point, a spark plug ignites the mixture. But in a diesel engine there are no spark plugs. The extreme compression of diesel and air generates so much heat that the mixture explodes spontaneously. This is known as “compression ignition” and is the basis of how a diesel engine works.

Here at Alpha Mobile Mechanics you are also part of the team, so we explain every detail related to the process and keep you aware of the way we complete this process.

Price difference

Diesel fuel, which is like syrup compared to gasoline (waterier), has more strength in terms of energy per unit of weight than this (for example, per gallon or liter). Therefore, although it often costs more than gasoline, it contains more potential energy, so less diesel than gasoline is required to achieve the same amount of work (in this case, driving distance). In terms of comparative costs, it is a small advantage for any fuel, depending on the price difference, the vehicle and the driving style. But, in general, the final cost to use any of the two fuels over time will be almost the same.

Diesel vehicle owners also have another fuel option: biodiesel, which is made from sources other than oil, such as frying oil or vegetable oil. In fact, the first diesel engines ran on fuel derived from peanut oil. And although making your own gasoline at home is very complex, dangerous and not advisable, it is possible to make biodiesel safely using prefabricated kits.

Power: Horsepower vs. Torque

Both engines are measured in terms of power and torque. Horsepower is a measure of power, while torque is a measure of the torque of a motor in the driveline. Large quantities of both are great, but if you have many horsepower with little torque, your vehicle will take a while to start. It is torsion that makes things move, which is why diesel engines are often used in large vehicles. They are ideal for moving heavy loads because they have a lot of torque, although they do not accelerate too much, since they have fewer horsepower on average than gasoline engines. It is also the reason why not many sports cars with diesel engines are seen under the hood.

What car manufacturers have discovered is that drivers love torque, both in trucks and cars. When you step on the accelerator, a diesel-powered car will have rapid acceleration. Together with a capable transmission, modern diesel engines can start up quickly and in a hurry. And while they will not reach speeds as high as gasoline engines, this is not usually a problem for most users, who prefer to have a (torque) acceleration power and good fuel consumption in the real world, rather than to achieve (in theory) high speeds that, otherwise, will never reach on highways or public roads, unless they want to earn a violation or visit to jail for reckless driving.

Reliability

Because diesel engines use compression ignition, they have a lot of resistance. And because they come from a legacy of workhorses, they tend to be reliable and require little care. They used to be heavy, but with modern manufacturing methods their weight has been reduced considerably and they are currently almost on par with gasoline engines.

In addition, a diesel engine is simpler, since it has no spark plugs or the electrical system associated with them. In general, a diesel engine tends to last longer than a gasoline engine in terms of the number of miles or hours before it needs a major overhaul, so repair bills are smaller and more spaced over time.

Pollution

This is one of the reasons why diesel engines have traditionally had a bad reputation, especially as a result of Diesel. But it must also be said that technology has advanced and made these engines cleaner than ever. In addition, many diesel cars now use an additive called DEF, also known as AdBlue. It is a liquid additive that is kept in a small tank a and that is used to make the diesel exhaust cleaner.

Many diesel cars now use a separate additive called DEF, also known as AdBlue. It is a liquid urea-based additive that is kept in a small tank on board the vehicle, and is used to keep diesel leaks and make it cleaner.

Noise

The first diesel cars sounded like trucks, yes, but once again, modern technology has greatly mitigated this situation. Noise pollution, often associated with old diesel engines, has disappeared along with those distant clouds of black smoke that were left behind.
