It is no secret that in Canada, diesel-powered vehicles are often associated with heavy trucks, buses and commercial vehicles. As for passenger cars, the diesel engine on such vehicles is not as commonly seen as the gasoline engine.

In this article, we will look at the main advantages and disadvantages of the diesel engine, as well as talk about when this type of motor can or, alternatively, cannot be considered an optimal choice.

Pros of the diesel engine

So, let us start with the obvious advantages. Fuel consumption of diesel engines, as a rule, is 30-35% lower than that of gasoline engines.

The diesel unit is more environmentally friendly, as it burns the fuel charge more efficiently. As a result, the toxicity of the exhaust of a modern diesel engine is significantly reduced. You can also check diesel catalytic converter to make your car more environmentally friendly.

In addition, the diesel engine has a high torque at lower RPMs, which makes it possible to achieve excellent acceleration dynamics when pulling off.

The motor operating time of the diesel engine is greater than that of gasoline engines. In practice, such a power unit, subject to competent servicing, is able to withstand about 350-400 thousand mileage, while a gasoline motor may need some major repairs after 200000 thousand kilometers.

The lack of ignition system in diesel engines eliminates a number of problems that are inherent in gasoline power units.

The design features and method of ignition of fuel in the cylinders from compression provide the diesel engine with a higher efficiency. In other words, as a result of burning fuel, more energy is converted. This means that the power of such an engine is greater. If you decide to opt for a diesel engine car, make sure to learn about diesel oxidation catalysts, as these devices can have a positive impact on the environment.

Cons of the diesel engine

span style=”font-weight: 400;”>First of all, we want to start with the cost. Diesel engine carы, on average, initially cost 25-35% more than the petrol counterparts (depending on the type and class of the car).

Even given fact that diesel engines now work at higher RPMs, cars with such a motor are still less speedy than gasoline engine cars. It is also worth noting that the diesel engine is heavier than the petrol one, which affects the weighting of the car, its dynamic characteristics and handling.

In the case of diesel engines equipped with a manual transmission, it is necessary to switch gears more often. If an automatic or robotic gearbox is installed on the diesel car, the service life of the gearbox may be less than that on the same petrol model. The reason is that the gearbox has to withstand a considerable torque.

The diesel engine warms up more slowly. The reason is that the efficiency of the diesel is higher, that is, less energy from the combustion of diesel fuel is spent on heating. As a result, the motor is more efficient, but less heat generation also means that such an engine warms up more slowly. In connection with your comfort, this may become a problem in winter.
