Is a diesel engine better?

Is a diesel engine better? Today we will discuss this issue.

According to Digital Trends and How Stuff Works, both gasoline and diesel engines use internal combustion engines. With this type of engine, air enters the engine and combines with fuel. The mixture produced by the compression of the engine's cylinders is ignited to trigger the movement of the pistons and crankshaft. The latter component activates the vehicle's transmission to turn the car's wheels. Then, the piston returns to its original position, and the exhaust gas from the engine is discharged as exhaust gas through the tail pipe. This process happens multiple times per second.

 

However, the ignition process of gas engines and diesel engines are different. During the compression process, the spark plug ignites the fuel in the gas engine. Diesel engines do not have spark plugs, but simply use extreme compression to generate the heat required for self-ignition, also known as compression ignition. When this phenomenon occurs in a gas engine, the engine will be damaged.

These sources, as well as Road and Track, point out that, compared to engines with fewer cylinders, engines with more cylinders provide greater power and smoother operation. However, these more powerful engines are also less efficient and more complicated to repair.

 

Choose the right engine type

According to Bell Performance and Road and Track, customers who drive many highway miles often prefer diesel engines because they are more efficient than gas engines on these roads. Compared with gas fuel, diesel fuel contains more energy per gallon, which makes it more economical overall. Diesel engines are still more efficient than gasoline engines, but for those who are mainly engaged in urban driving, they are less efficient. Diesel cars also have greater torque, which leads to better fuel economy and more impressive acceleration.

 

It is important to remember that certain types of diesel fuel can have a negative impact on vehicle performance. These include black diesel, biodiesel and other enhanced diesel products.

 

For most American consumers, the cost of diesel fuel and gaseous fuel are roughly the same. Sometimes the price of diesel is higher than that of natural gas, and sometimes it is lower than the cost of natural gas. However, even if you spend more on diesel fuel, you will still get more economy from the diesel engine throughout the life of the vehicle. That's because you need an 8-liter gasoline engine to get the same power as a 6-liter diesel engine.

 

Digital Trends reports that diesel engines tend to be more durable than gas engines, have a longer service life, operate reliably, and require minimal maintenance. Although diesel cars used to be much heavier than gasoline cars of the same size, this is no longer a problem due to modern manufacturing methods.

 

Diesel engines also have fewer parts than gas engines, which means that your car has fewer potential parts for failure. Most diesel engines require fewer repairs and maintenance services than gas engines, which represents overall economic savings.

 

Although the early diesel engines had a reputation for being noisy, most of these complaints have been resolved through new technologies. Problems such as noise pollution and black smoke have been alleviated, so if you have been plagued by these problems in the past few decades, you may want to put diesel back into your list of possibilities. Today, your driving experience on a diesel-powered car is almost the same as the experience of driving a gas-powered car.

 

Calculate diesel cost savings

 

The formula you need is as follows:

 

Miles/(city MPG * percentage of your mileage in the city + highway MPG * percentage of your mileage on the highway) * per gallon $ $ = annual gas cost

 

When you calculate these numbers yourself, you may find that although the cost per mile of diesel fuel is lower than that of gasoline, it will take many years to break even if the cost of a diesel vehicle is compared with the cost of a gas drive. vehicle. However, if you drive many miles on the highway each year and plan to use diesel vehicles for long periods of time, you may find that paying upfront for more efficient engines makes sense, especially when you consider annual fuel costs.

 

Also, keep in mind that if you change the percentage of city mileage to highway mileage, or if you drive more or less mileage each year than expected, the break-even point of diesel vehicles will change. Drivers who drive less than 10,000 miles a year on average will not be able to limit fuel costs to a level that makes diesel engines economically meaningful, unless they rarely drive in cities or currently drive vehicles that require high-quality gasoline.
