How is fuel ignited in the engine?
How is fuel ignited in the engine?
In a spark-ignited system, the fuel is injected into the combustion chamber and combined with air. The air/fuel mixture is ignited by a spark from the spark plug. Although gasoline is the most common transportation fuel, there are alternative fuel options that use similar components and engine systems.
What is ignited fuel?
Spark ignition gasoline and compression ignition diesel engines differ in how they supply and ignite the fuel. In a spark ignition engine, the fuel is mixed with air and then inducted into the cylinder during the intake process. After the piston compresses the fuel-air mixture, the spark ignites it, causing combustion.
How is diesel fuel ignited in a warm diesel engine quizlet?
How is diesel fuel ignited in a warm diesel engine? Technician A says that glow plugs are used to help start a diesel engine and are shut off as soon as the engine starts.
Which fuel is the easiest to light?
Light (Watery looking) fuels like white gas or alcohol, have a low flashpoint (Below 0°) and will readily light when a flame is in its vicinity. Heavier (Oilier) fuels like kerosene and lamp oil have a much higher flashpoint.
Is the fuel ignited by the ignition system?
In diesel engine the fuel is injected by fuel injector with plunger arrangement to supply at very high pressure. It does not need spark plug for ignition as the compression ratio of the diesel engine is very high.
How does fuel get into a diesel engine?
Fuel is injected into the cylinders, where it is ignited by squeezing the diesel and air together making an explosion. This explosion moves the pistons, doing work, allowing the vehicle to move forward. Pistons are devices that slide up and down inside the cylinders.
How does a diesel engine burn hot air?
The diesel is then atomized in the injectors, and a mist is sprayed into the hot air. The hot air immediately ignites the fuel, providing ignition. This ignition makes the diesel burn with oxygen from the atmosphere, which turns the chemical energy into increased temperature, which allows the gas to push back out on the piston, see figure 1.
How does a diesel engine use a spark?
A Diesel engine IS a compression-ignition engine. Instead of using a spark to ignite fuel like a gasoline engine, it uses the pressure and temperature reached during compression of the intake gas to ignite the fuel.

How is a diesel engine different from a gasoline engine?
The diesel engine is one type of internal combustion engine; more specifically, it is a compression ignition engine, in which the fuel is ignited by being suddenly exposed to the high temperature and pressure of a compressed gas, rather than by a separate source of ignition, such as a spark plug, as is the case in of the gasoline engine .
The diesel is then atomized in the injectors, and a mist is sprayed into the hot air. The hot air immediately ignites the fuel, providing ignition. This ignition makes the diesel burn with oxygen from the atmosphere, which turns the chemical energy into increased temperature, which allows the gas to push back out on the piston, see figure 1.
Why does a diesel engine have a high temperature?
The high temperature of the air in the cylinder is due to the adiabatic compression. These engines only compress the air and not the fuel. When injected into the combustion chamber, the Diesel fuel undergoes spontaneous ignition.
