All diesel engines use fuel injection by design. Petrol engines can use gasoline direct injection, where the fuel is directly delivered into the combustion chamber, or indirect injection where the fuel is mixed with air before the intake stroke.
On petrol engines, fuel injection replaced carburetors from the 1980s onward. The primary difference between carburetors and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while a carburetor relies Еще
The fuel injection system lies at the very heart of the diesel engine. By pressurizing and injecting the fuel, the system forces it into air that has been compressed to high pressure in the combustion chamber. Еще
