Multiple Benefits Of Diesel Engines For Trucks By Rj Performance

1. Multiple Benefits of Diesel Engines for Trucks
The population growth and relentless customer demands led to increased use of movement of goods and hence
the transportation sector was also forced to move up the value chain from archaic techniques to more
constructive and substantive strategies. In this context, the invention of the diesel engine opened up new
opportunities and helped the transition in the transportation sector that had far-reaching impact to yield
unprecedented benefits.
In the diesel engine, the basic scientific theory that energy can neither be created nor destroyed is used and the
chemical energy is transformed into mechanical energy. When the pistons that are connected to the crankshaft,
are moved up and down by this mechanical energy, rotary motion is created moving the truck forward.
The chemical energy is available from diesel, the fuel, and when the fuel burns, energy is created. But in a diesel
engine, combustion of fuel takes place only when the fuel is injected into the cylinder when the compressed air
reaches a particular level. Heat created by the compressed air starts burning the injected fuel.
In trucks, four-stroke diesel engines are used. The four strokes are called the intake stroke, compression stroke,
combustion stroke and exhaust stroke. In the intake stroke, air is taken in to move the piston down.
Compression stroke, as the name suggests, involves compression of the air taken in. When the compression of
air reaches a specific point, fuel is injected and ignited with the heat of the compressed air. This is the point
when compression stroke works to bring the piston down. Again when the piston moves to the top, the exhaust
created is pushed out in the exhaust stroke. Since the fuel is directly injected and ignited due to the
compressed air, there is no spark plug in diesel engine trucks.
In the truck diesel engines, fuel is injected into the cylinder directly. This injector is the most complicated part
of the truck diesel engine. For placing it in the right location, a lot of experiments are carried out because it
should cope up with the temperature and pressure of the compressed air inside the cylinder. At the same time,
it should perform its duty of injecting the fuel at the right moment. To distribute the diesel mist evenly in the
cylinder, in some engines, specially designed induction valves and other devices like pre-combustion chambers
are used.
ECM with the help of sensors is the controller of almost all the functions in a diesel engine, right from
monitoring the R.P.M., engine coolant and oil temperatures to determining the engine position. In a cold
weather, when the outside air is cold, the ECM retards the timing of the engine suitably so that the fuel is
injected a little later when the compressed air develops more heat than in normal weather conditions.
Diesel Fuel is heavier and oilier than gasoline and also evaporates more slowly. Diesel is got by a less refining
process than gasoline and hence it is cheaper. But the energy density is higher. If the diesel engine is
maintained well and is in top condition, you get more mileage. The emission levels of diesel are also better
because diesel emits less of undesirable emissions that threaten the global environment.
