Advantages and Disadvantages of Diesel Engine

The second most popular diesel engines are used in modern cars. Some people would be the main driver of the car in the near future; some people say the diesel engine is not used. Nevertheless, the diesel engine fuel impending crisis continue to address the problem of private and public transportation fuels and fuel volume more quickly to produce a million worldwide. The diesel engine will evaluate whether an appropriate solution.

Advantages

The main advantage of diesel fuel is low. Then, diesel fuel, gasoline AI-98 cost difference between expensive cars even begin storing owner, and reached a level of 20%. The fuel efficiency of a diesel engine 36% more. The efficiency of gasoline engines, diesel engines are less waste fuel than gasoline powered engines thus only 25%.

Compared to gasoline engines, a diesel engine of the same volume of the combustion chamber has the advantage of high torque. It is very important for a minivan and wagon breaks. The alternative engine is now mounted on the truck. High torque is helpful in city traffic; allow the engine to move the minimum turnover in traffic.

Disadvantages

The main disadvantage of diesel engines is that high. They also maintain all the expensive production (due to the high workload). Evaporation and the need for ecological compatibility in accordance with the stringent requirements of international agreements, it is expensive because it controls the exhaust.

Diesel fuel ignition by the heat of the compressed air. This results in that the fuel does not sufficiently generate the time and combustion CH, NOx and soot to mix with the air. Carbon black, the color below, is particularly evident in the black exhaust gas. To remove the catalyst, but in the case of hydrocarbons, and further the amount of soot in the exhaust gas is controlled by a special exhaust filter positioned between the exhaust manifold and catalyst. Carbon black and warm exhaust filter in the exhaust gas stream generated by the afterburner. Due to be fired at regular intervals, the residual carbon black and the command is a command blocks gas temperature, increase the combustion in the combustion stroke to the amount of added fuel.
