ما الفرق بين محرك الديزل و محرك البنزين؟! Diesel & Petrol Engine

يختلف محرك الديزل عن محرك البنزين
و ذلك من عدة أوجه
تبدأ من فكرة العمل و نسبة الانضغاط و التكلفة و الحجم و الوزن و اختلافات كثيرة هنشوفها مع بعض فى الفيديو
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 13.
Not only are diesel engines more efficient, diesel fuel is also cheaper to purchase. At the time of writing, diesel fuel is around 40% cheaper per liter than petrol. 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 1000km on a single tank. This means more time spent traveling and less time spent refueling.
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 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.
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.
