What are the advantages of a diesel engine?

Rising fuel prices, especially for diesel fuel, has attracted worldwide attention, and around the diesel technology is not subsiding controversy. At the same time, proponents of the “Diesel” result in a number of arguments in its favor.

1. Diesel engines continue to consume less fuel than gasoline

Despite the fact that modern technology – such as gasoline direct injection and the concept of minimizing – to help further improve the gasoline engines, reducing fuel consumption, “Diesel” is still superior to them in this regard.

Modern “diesels,” spend about 30% less fuel than gasoline engines with direct injection of the same generation. Diesel car of the compact class for the previous generation consumed 31% less fuel than a gasoline engine with injection through the intake manifold. The latest generation of diesel engines by 29% more economical than petrol engines with direct injection, turbocharger on exhaust gases and a reduced displacement.

2. Diesel engines are more economical in terms of overall operating costs

In many classes of cars “diesel” is still the leader in terms of total annual operating costs. In addition, long known that the benefit depends on the annual mileage cars: the higher it is, the greater the effect of low fuel consumption.

This is confirmed by several studies, for example, according to the German automobile association ADAC, with an annual mileage of 20 thousand kilometers, “89% of diesel cars are more efficient than their gasoline counterparts.”

3. Distribution of “diesel engine” helps implement a program to reduce the emission of CO2

Thanks to lower fuel consumption diesel engines emit about 25% less CO2, than conventional gasoline engines.

The tendency to buy large cars can have a positive impact on the balance of CO2 – many of them are equipped with diesel engines.

Automakers will be able to reach EU targets on emissions CO2 (120 g / km) only if the diesel models will retain or increase their current share of all new cars in the EU – around 50%.

4. A tax on CO2 – another economic argument in favor of “diesel engine”

A tax on CO2 emissions, diesel cars will make even more advantageous, as they emit about 25% less carbon dioxide than gasoline. Consequently, owners of diesel cars will pay less tax.

5. Diesel engines continue to improve

A number of solutions will soon allow to further reduce fuel consumption and CO2 emissions of diesel engines: the projected engineers “Bosch” – 10% by 2012.

Today offers a variety of technologies for gasoline and diesel engines. For example, the concept of minimization will reduce the displacement without loss of power, reducing fuel consumption and emissions in the engines of both types. The same results and helps to make technology “start-stop”.

In other words, engineers strive to realize the potential of further reducing fuel consumption and harmful emissions – as a diesel and gasoline in cars. Both technologies are developed in parallel to this direction.

6. Diesel cars are gaining ground in world markets

The share of diesels among new cars in Western Europe remains unchanged compared with 2006 and 2007, and in the UK is gradually increasing. The sharp rise in demand for diesel cars has recently seen in France, where in 2008 introduced a system of “bonus-malus,” in which buyers of cars with low CO2 emissions will receive discounts.

From the beginning, the share of diesels among new cars registered in France, has grown by about 6 percentage points – from 74% in 2007 to almost 80%.

The growth in popularity of gasoline direct injection has no effect on the distribution of diesel, but leads to the exclusion of injection through the intake manifold.

Non-European countries are also seeking to reduce vehicle emissions and fuel consumption by introducing appropriate legislative measures. American buyers, for example, are increasingly interested in cost-effective and environmentally friendly engines.

In addition, the U.S. seeks to reduce its dependence on imported crude oil, and diesel engines, with their lower fuel consumption can play a key role in solving this problem. Experts expect that by 2015 diesel engines will be fitted with 15% of all new cars and light trucks in the U.S..

7. New emissions standards will not necessarily lead to higher prices of diesel vehicles

Reduction of nitrogen oxide emissions in compliance with “Euro 5”, which enter into force in Ukraine in 2014, does not require the use of expensive technologies. In many cases – depending on the car – Modern diesel injection technology in combination with the optimization of combustion will fulfill even the norm “Euro 6”, without the high cost of processing the exhaust gases and other additional costs. Now engineers are working on creation of the necessary equipment for this.
