Why trucks burn diesel? Tell you minute by minute

Gasoline said it was violent, kerosene said it was cheerful, then diesel's character can be described as stable, it can be divided into light diesel (car/truck) and heavy diesel (heavy machinery/medium and small ships) two kinds, the latter compared The former has higher density, higher calorific value, higher burning point, and more viscous. Because the characteristics are stable and the ignition point is low, it can be ignited without worrying about the deflagration phenomenon. A large combustion chamber can be made, and gasoline cannot.

Large diesel engine

For some ships and heavy machinery, because of the high load required, there is no requirement for speed increase, but the power and torque (especially torque) are highly demanded. The high calorific value of diesel plus the high compression ratio of diesel engine can make full use of it. Energy, although the speed does not go up, but the power is not that the gasoline engine can match.

Light diesel engine

For trucks using light diesel oil and some domestic cars, the advantages of simple diesel engines, high reliability, and low fuel consumption stand out because they do not have much demand for acceleration performance. In addition, the diesel engine will also deposit carbon, but the adverse reaction of diesel engine to carbon deposition is not very sensitive, especially heavy-duty diesel engines, the manifold is so thick, the effect of carbon deposition is complete mosquito legs.
