One of the confusions prevailing among the car buyers is the difference between the petrol gasoline engine and the diesel engine. Perhaps the common knowledge or perception is that the diesel motors are noisier and their vibration is intolerable, whereas petrol motors run smoothly.

This mechanical energy moves pistons up and down inside cylinders. The pistons are connected to a crankshaft, and the up-and-down motion of the pistons, known as linear motion, creates the rotary motion needed to turn the wheels of a car forward. Both diesel engines and gasoline engines convert fuel into energy through a series of small explosions or combustions.

The diesel and petrol engines that are used in most cars are highly similar. In essence, they are internal combustion engines that work using a two or four-stroke cycle. In an internal combustion engine, the power cycle is made up of four phases: intake, compression, power and exhaust.

In the intake phase, air is drawn into cylinder through the opening intake valve. In the compression phase, the intake valve closes and air is compressed with fuel. At this point, the mixture of fuel and air is ignited to cause an explosion. It is this explosion that causes the piston to downwards and drive the crankshaft to produce motion.

This is the power phase. The final phase is exhaust where the spent air-fuel mixture is expelled out of the cylinder through the opening exhaust valve so that a new cycle may begin. The main difference between diesel and petrol engines is that petrol engines use spark plugs to ignite the air-fuel mixture, while diesel engines rely solely on heavily compressed air.

As mentioned earlier, Rudolf Diesel found that the temperature of air could be made to increase high enough if it was heavily compressed. The temperature would rise so high to the point where it could cause the ignition of diesel fuel. Therefore in diesel engines, air in cylinder would be very heavily compressed, typically to around 14 to 23 times its original volume. In petrol engines, the compression ratio is generally much lower, because they rely more on the spark plug to begin the power phase.

The compression ratio is petrol engines is typically around only around 7 to 10, with high performance vehicles having higher compression ratios of up to High compression ratios are desirable because it results in higher thermal efficiency. In other words, more energy can be extracted out of the air-fuel mixture. This also explains why diesel engines are considerably more efficient than petrol engines.

In fact, diesel engines have the highest thermal efficiency of any internal combustion engine. Besides being very efficient, what other advantages do diesel engines have over their petrol counterparts? And what disadvantages do diesel engines have? Petrol, on the other hand, are subjected to a petrol duty which, according to the LTA, encourages fuel conservation and discourages excessive use of petrol cars that may contribute to congestion and pollution.

But times have changed dramatically in the past decade. Diesel technology has improved rapidly, and governments are recognizing the environmental benefits that diesel cars have and have put legislations in place to promote their sales. As a result, sales of diesel cars have been on the rise. In many European countries, such as Austria, Belgium and Germany, sales of diesel cars are on a par with or have even surpassed that of petrol cars.

In Singapore, sales of diesel cars are on the rise, albeit slowly. Knowledgeable car buyers are now open to trying out diesel and that has been helped in part by the government, who has revised the special tax on diesel cars.

For modern diesel cars which meet the Euro V standards, the special tax has been drastically reduced. To get a sense of how much cheaper it is to drive a diesel car now, one only has to look at the tax rates. For a pre-Euro IV compliant car , the special tax is a whopping 6 times the road tax of the petrol equivalent.

But thanks to the more favorable tax rates, it is now more affordable and financially practical to drive a diesel. Have feedback on the article for the editorial team? You can reach out to them here. Subscribe to the latest tech news as well as exciting promotions from us and our partners!

Why you should consider a diesel as your next car By Kenny Yeo - 24 Jul Page 2 of 3. Diesel vs petrol engines How are diesel and petrol engines different? The Pros and Cons Besides being very efficient, what other advantages do diesel engines have over their petrol counterparts? Pros Not only are diesel engines more efficient, diesel fuel is also cheaper to purchase. This means diesel vehicles will be cheaper to run, which also explains why buses and most taxis have diesel engines.

Because diesel engines are so efficient, cars can get incredible mileage out of them. It is not uncommon for passengers cars with modest 50 liter fuel tanks to be able to travel over km on a single tank.

This means more time spent traveling and less time spent refueling. To withstand the high compression of gases within the cylinders, diesel engines are built to be extremely hardy and will generally last longer than their petrol counterparts. They can also go longer between maintenance. Diesel engines can be made to run on alternative and renewable fuels like biodiesel with little or no modifications.

Biodiesel generally refers to used vegetable oil that has been used for cooking, and is then recycled and treated so that it can be used to power diesel cars. Cons Diesel engines need to be built stronger to withstand the high compression of gases, as a result, they usually cost more to manufacture. Consequently, diesel cars can sometimes cost more than their petrol equivalent. This depends heavily on the manufacturer.

Diesel engines produce a distinctive knocking sound that is referred to as diesel clatter. This sound is the result of the sudden ignition of fuel which causes a pressure wave.

It makes diesel engines sound less refined and noisier. Diesel engines are heavier and less eager to rev than petrol engines, which makes them undesirable in sports cars.

This also makes diesel powered cars less peppy and engaging to drive. In Singapore, diesel cars are subjected to a special tax on top of the typical road tax which can add to the running costs of the car. Since this tax can be substantial, we will address it in greater detail below. Here's a table to recap the various tax payable using a car with a cc engine as a comparion.

Diesel is an increasingly popular fuel in European cars, with over half of new registrations of this type. What are the differences between these two propellants? Conventional diesel and petrol are both produced from mineral oil, but the precise refining methods vary. Diesel is in principle easier to refine than gasoline, however it contains more pollutants that must be extracted before it can reach the same levels of emissions as petrol. The calorific value of diesel fuel is roughly Crude oil contains hundreds of different types of hydrocarbons all mixed together and, depending on the source of the crude oil, different impurities. In order to produce petrol, diesel or any other oil-based products, the hydrocarbons have to be separated, by refining of one type or another:.

Если по какой-то случайности кольцо попадет не в те руки, я бы предпочел, чтобы мы уже внесли нужные изменения в алгоритм. Тогда, кто бы ни стал обладателем ключа, он скачает себе нашу версию алгоритма.  - Стратмор помахал оружием и встал.

 Тот, что был в парке. Я рассказал о нем полицейскому. Я отказался взять кольцо, а эта фашистская свинья его схватила.

Беккер мрачно оглядел море красно-бело-синих причесок. - Что у них с волосами? - превозмогая боль, спросил он, показывая рукой на остальных пассажиров.  - Они все… - Красно-бело-синие? - подсказал парень.

Это был Чатрукьян. Он снова постучал. У него был такой вид, будто он только что увидел Армагеддон.

Тридцать лет отдал он служению своей стране. Этот день должен был стать днем его славы, его piece de resistance, итогом всей его жизни - днем открытия черного хода во всемирный стандарт криптографии. А вместо этого он заразил вирусом главный банк данных Агентства национальной безопасности.

 - Это составляло половину того, что у него было, и раз в десять больше настоящей стоимости кольца. Росио подняла брови. - Это очень большие деньги. - Конечно. Договорились.

 Диагностика, черт меня дери! - бормотал Чатрукьян, направляясь в свою лабораторию.  - Что же это за цикличная функция, над которой три миллиона процессоров бьются уже шестнадцать часов. Он постоял в нерешительности, раздумывая, не следует ли поставить в известность начальника лаборатории безопасности.

Стоя над Хейлом и стараясь унять дрожь, Сьюзан услышала приближающиеся шаги и медленно обернулась. В проломе стены возникла фигура Стратмора. Он был бледен и еле дышал. Увидев тело Хейла, Стратмор вздрогнул от ужаса. - О Боже! - воскликнул .
