The Ultimate Choice – Diesel and Diesel only?

The main difference between the gasoline engines and diesel engines is the type of ignition. In gasoline engines ignition is done by spark plugs, whereas in diesel engines it is done by compression. The air is drawn into the engine and subjected to high compression that heats it up. The result is a very high temperature in the engine, much high than that of gas engines.

With the diesel engine, unlike gas engines where a mixture of air and gas are introduced, here (in diesel engine) both air and fuel are infused into the engine at different stages. The fuel is injected into the diesel using an injector where in a gas engine, a carburetor is used for this very purpose.

In gas engines, at the same time fuel and air are let into the engine and then compressed. Fuel compression will be limited by the mixture of the air and fuel, and thereby hence the overall efficiency. In diesel engines result ratio can be much higher as they only compress air.

Merits
While comparing the both gasoline and diesel engines, diesel engines are found much more efficient and preferable. There are few reasons telling the same:

1. The several problems of earlier models like higher noise and maintenance costs, have been removed in latest diesel models. Now, they are quiet and require less regular maintenance when compared with gas engines of a similar size.

2. As compared to gasoline engines diesel engines are more rugged and reliable.

3. For fuel ignition there is no spark plug used in diesel engines at all which will obviously help you save the repairing again and again like in gasoline.

4. The well known advantage is the fuel cost produced is 30 – 50 percent    lower than gas engine fuel prices.

5. Gasoline engines have shorter life span when they are compared with diesel engines.
