Diesel ... truths and lies


Diesel ... truths and lies


Following the latest developments in the diesel versions will be added to 
the good in our life and judging by their sales in other European countries are close to 50% of the total, or in some cases surpass the outlook is promising ...


Of course, from country to country differences in habits and conditions, which play a crucial role for the correct answer the question "oil or gasoline." For example, in most Central European countries, covering relatively long distances to and from work is the norm in Greece on the other not, while important factor is of course the total cost of the car. In our country with special tax-based system for both the cubic market and for evidence and any extraordinary contributions during the generally larger displacement diesel engines do not always have the advantage on their side. Let's see some interesting facts and some beliefs about diesel engines. The diesel engines are assumed to be cheaper than the equivalent petrol due to construction, as spontaneous combustion achieved due to high compression of the fuel mix results and better efficiency than gasoline engines with spark plugs. Addition to diesel, for this reason, there is a fuel mixture of excess air, which also has a positive effect on consumption. Parallel and diesel fuel has a higher energy content than gasoline. The high compression ratio of engine oil has as a consequence this feature and more intense sound that makes them seem less civilized. The trend in modern ensembles as the Mitsubishi ASX or the new Mazda CX-5, is to reduce the compression ratio with a corresponding reduction in noise perceived mostly from outside the car and not inside it. Outside the car is perceived and the smell of diesel, which seems more intense than that of gasoline. In fact there is more intense-indeed, in both cases due to the chemical composition of these fuels over them and add them, so they vary from brand to brand, but it is different and so it sometimes bothers us most. It So obvious that diesel is now cheaper than the equivalent petrol similar or similar effect. How? To be realistic we must calculate a 20%, and a diesel as their respective stations, the most important factor is still the driver. To see if we really worthwhile to buy diesel should note your additional cost market generally exists to determine the mileage on an annual basis. Credit for any difference in price l see when you do these depreciation of the smallest consumption and decide. The rule wants oil to cost as much kilometers do one time. In some categories, however, cars such as SUV and large MPVs oil is practically the only way, as the differences in consumption are more important than in other categories, due weight body, increased friction transmission, etc., towing a trailer. Besides all anything but coincidence is that in other European countries all are moving jeep and diesel engine range includes significantly less gasoline. To get a picture, however, what will happen in the future, note that the small (mini) until the middle category of the modern petrol engines if not already quickly become as affordable as the diesel. Due to downsizing, direct injection and turbo. The latest in diesel for years considered a sine qua non. Generally, experts talk about opportunities to reduce consumption by up to 40% for petrol engines for the next few years, while the rate for diesel is more than 15%. One and the car gets one for several years note that within the European Union there is a debate about reducing or eliminating the tax advantage currently has oil to petrol or taxation not in volume but the energy content of fuel. In each case the result will be a significant increase in oil prices. The decision, if and when received, should be unanimous and that is an additional difficulty may trenarei to any change. The diesel engines are much more ropatoi and therefore more resilient than low compared with gasoline, but on the other are obviously smaller operating range, since the maximum power occurs at most until 4,000 rpm In practice this means a greater involvement of the driver box. The ideal combination is a diesel engine and automatic transmission. Listen to us and will not lose. The diesel is heavier construction, by an equivalent gasoline. If you are very careful and experienced you may find a greater inertia in the front. Manufacturers, however, do kapooies micro-changes in shock absorbers and springs for the differences in practice be negligible as long as possible. The heart of modern diesel engines is the fuel pump, operating at very high pressures are particularly sensitive to the fuel poor and expensive to repair (and not always covered by warranty). The "dirty" as many say oils are usually derived from fraud, so here is even more important to refuel at gas you have convinced the quality of fuel they sell. As far as possible. Oil is more sensitive to low temperatures than that petrol. Refineries adjust the product produced according to the climatic conditions of each season, although in our country the problem is only locally intense. The problem of micro-particle emission from diesel engines is a real, albeit significantly reduced by Euro standards 5 and 6. But in any case, private diesel models that meet these standards and are moving in the streets of Athens and Thessaloninis will enhance the problem, apart from industrial activities and the central heating is caused mainly by trucks and buses Old technology in addition to a large proportion is preserved and bad. Something that is of course also for taxis. Unlike the diesel does not have issue with the emissions of CO2, so there's no extra expense in terms of road taxes.
