Car Engine – Petrol Vs. Diesel

Car engine is a lump of metal fitted in the car that makes the car go zooming. The traditional types of car engines are petrol and diesel. Since the introduction of cars on the Indian automobile industry, these two types of engines are dominant and are still among the highest fuel used for fueling the engines.

Although many alternative fuel as LPG, CNG, compressed air and water are now used to drive motors, gasoline and diesel engines hold their positions on top. But they differ a lot in terms of power, performance and output.

Here we will discuss the fundamental distinction between gasoline engine and diesel engine.

Gasoline Engine

Gasoline engine is one of the traditional types of car engines running on gasoline. The first gasoline engine was introduced by two skilled engineers from Germany, Gottlieb Daimler and Karl Benz, this year the 1885th This type of car engine is composed of nearly about 150 moving parts that support the burning of fuel with the use of spark plugs and cause expansion of hot gases.

The gasoline engine is pre-mixing fuel and air allows the car to run at a higher speed but with lower fuel economy.

Diesel Engine

A diesel engine is a combustion engine running on diesel. Named after Dr. Rudolph Diesel, this type of engine uses compression ignition to burn the fuel which is injected into the combustion chamber after the air is compressed.

Diesel engines traditionally used in large Automotives as trucks, locomotives, and ships instead of the steam engines. Later, the same used in Automotive and cars for long distance driving and better efficacy.

Petrol vs Diesel

In India, gasoline more expensive than diesel and that is why many people prefer diesel cars especially those with long distance commuting on a daily basis.

When the time comes to resell the car, diesel cars have better resale value compared to gasoline counterpart. This is because many people believe that diesel vehicles run longer than petrol cars because petrol destroys lubrication, but not diesel.

It is also said that gasoline reduces fuel economy compared to diesel cars. If gasoline supply one kilometer around 60 mpg, so diesel counterpart will deliver almost the 70-80 mpg. On long distance drives and long routes are diesel cars much preferred over gasoline siblings.

The compression ratio in diesel engines is 22:01, which makes it difficult to start the engine while in the case of gasoline engine, the engine is more likely to start at a faster speed compared to the diesel engine.

Petrol engines are relatively lighter than the diesel, but diesel still give them more torque which makes them better for towing.

Diesel engine makes driving more cumbersome and uneasy over gasoline engine. Diesel engine makes wheel tongue and thus drive needs an extra pressure.

Gasoline produces less noise and vibration than the diesel car engines.
