How a Diesel Fuel Injection System Contributes to Fuel Efficiency?
The diesel fuel injection system has undergone many changes over the years. Previously, cars used to have a carburetor installed in them, but such cars are no longer on the market. On the other hand, the fuel injection system has been around since the 1950s and electronic fuel injection (EFI) was installed in European Cars during the 1980s. Now, almost all fuel injection service, including diesel injection service and petrol injection service, will supply fuel injection systems. When people think of the word "diesel", most people will think of huge trucks releasing a lot of black soot and gases that cause a great deal of harm to the environment. However, most container ships still rely on diesel to travel long distances across the ocean. Diesel is still mainly used in heavy vehicles like trucks.
Diesel fuel injection system
Both engines convert fuel into energy via a series of minor explosions or combustions. However, the way the combustion happens is different in both engines. In gasoline engine, the air is mixed with fuel and the combined substance gets compressed by pistons. The explosion is ignited by a spark. On the other hand, in a diesel engine, air is compressed first which causes the air to heat up. Then the fuel is injected, which ignites the explosion.
This is probably the way diesel fuel injection systems differs from gasoline injection systems. In the gasoline injection system, all the chemicals are injected first, then compressed. The problem with this system is getting the right amount of compression pressure. If the mixture is compressed too much, what will happen is that the mixture explodes together at the same time, causing knocking. Knocking can damage the engine. On the other hand, the diesel fuel injector system directly injects fuel into the system. The injector is a very complicated part, and massive research has been done to improve it. The injector can withstand high pressure and deliver the fuel in a fine mist form. Some diesel engines employ induction valves, so that the fuel can get circulated in the engine.
Glow plugs
Some engines contain glow plugs. The function of the glow plug is to raise air temperature so that ignition can occur in the car engine. Sometimes when compression occurs, no ignition might happen. The glow plugs will then raise the temperature high enough to ignite the fuel.
The future of diesel injection system
In the past, scientists experimented with diesel for fuel energy. The results were disappointing. Burning diesel in a car often gives out a lot of black soot and the engines were giving out loud noises. However, in modern times, an increase in technological advancement has made diesel burning a lot more efficient and cleaner. Direct injections are now controlled by computers.
