Should I still buy a diesel car?

0 0

The advantage of a diesel engine lies above all in its lower consumption of power, combined because of lower taxes at the lower price of diesel fuel at the pump. That’s why the Diesel still accounted for almost two between thirds of new car sales in 2014. In return, it costs more to buy and also to maintain (because mechanics in a diesel car is more complicated than a gasoline engine, for this reasons they construct diesel car with more strong object ) but, the insurance bill is more expensive than gasoline cars, in some countries they encourage the purchase of electric vehicles by the exoneration of taxes.

These additional costs in practice remove any economic interest in Diesel for small distances. The depreciation threshold of a diesel car compared to its gasoline equivalent can be estimated at around 20,000 kilometers per year, a mileage that 71% of diesel cars did not reach in 2012, according to a study by the UFC association.

Is Diesel more dangerous to health than gasoline?

Once praised for its low greenhouse gas (CO2) emissions that led the state to subsidize it with ecological bonuses in the late 2000s, the Diesel is now singled out for its particulate emissions carcinogenic. A little late, while the bonus and the scrappage have massively favored the sale of diesel models without particle filter.

On the other hand, the Diesel in optimal conditions of use, is theoretically less polluting than a gasoline engine: it has an advantage as far as the CO2 emissions, while its systems of depollution evolved allow it to control its emissions of particulates and nitrogen oxides (NOx). In practice, the particulate filter requires proper use of the vehicle to avoid clogging (road trips) and rigorous maintenance to remain effective and reliable. In addition, the finest particles, which are also the most harmful, escape from the filter.

Petrol engines are following the same path, the widespread use of direct injection reduces consumption and CO2 emissions to the detriment of fine particle emissions, which will ultimately impose the use of a particulate filter. But gasoline engines do not face the problem of nitrogen oxides (NOx), other dangerous diesel emissions and very expensive to clean up.

CO2 is not the only gas emitted by cars. NOx (nitrogen oxides) are part of it, and diesel produces more.

At equal power, the higher torque of the Diesel is appreciable in times (accelerations launched), a stronger argument on large vehicles. Nevertheless, even with the best diesel engines, it is necessary to reach a particular regime (generally between 1500 and 2000 rpm) before obtaining a short answer. This lack of flexibility at low speeds can generate jerks in the city. Similarly, it is seldom necessary to climb above 4,000 rpm, the engine not being more efficient beyond. To exploit the punch of a diesel engine optimally, it will, therefore, play the gear lever. An automatic transmission will of course greatly reduce these disadvantages, but the Diesel will always struggle to compete with the flexibility of gasoline engines, especially as they now combine a much higher torque with the generalization of the turbo.

Is Diesel likely to be banned from some cities?

Nevertheless, the Netherlands is on the right way. With one of the lowest levels of CO2 emissions and the sale of electric cars is progressing strongly. Amsterdam is the capital of bicycles. Their inhabitants make nearly 60% of their trips by bike.Netherlands who want to end CO2 emissions by the use of electric cars in 2030, the law has already been debated in Parliament and is now in the hands of senators.On the other hand, this law think about measures to facilitate the purchase and use of electric cars.

The electric cars

There are now several alternatives to the diesel engine that pollutes. in order that electric and hybrid cars make up the bulk of the fleet, electricity remains the primary solution to replace fuel and research is just beginning.

Globally, the electric car market surpassed 2 million sales in 2016. The largest market is China, followed by the United States, Norway, Japan, and France. This is a 40% increase in sales, which however represents only 8% of global auto sales.

Some Electric Car Companies

Tesla, BMW, Nissan, Chevrolet, Ford, Volkswagen, Kia, and many more companies are specially from china. The Chinese BYD remains a great competitor but focused primarily on its domestic market. His small car “BYD EC” will have sold 92,000 copies. And the Renault-Nissan-Mitsubishi Alliance remains well established in this leading trio, among others 3 successful models, the Nissan Leaf, The Renault Zoé and the Mitsubishi Outlander PHEV.
