At Central Diesel, we are a distributor of diesel engines and diesel engine components. One of our core product offerings is fuel injection systems and parts, which are designed to consistently deliver precise combinations of fuel and air to engine cylinders. Compared to the carburetors they ultimately replaced, they offer better fuel efficiency, drive consistency, and easier servicing requirements. Below, we highlight the types of fuel injection systems available and our product offerings.

Types of Fuel Injection Systems

Fuel injection systems can be categorized into four basic types:

Engine under hood of carSingle-Point Fuel Injection Systems

Single-point systems—also known as throttle body injection systems—are the original iteration of fuel injection systems. They were used to replace carburetors by adding one or two fuel injector nozzles to the throttle body. While they offer less precision than other systems, they are much cheaper and easier to service than carburetors.

Multipoint Fuel Injection Systems

Multipoint systems—also known as port injection systems—have a separator injector nozzle for each engine cylinder located outside of its intake port. They offer more precise fuel metering than single-point systems, which makes them better at achieving the desired fuel-air ratio and less likely to cause fuel condensation or collection in the intake manifold.

Sequential Fuel Injection Systems

Sequential systems—also known as sequential port fuel injection or timed injection systems—are a type of multiport system. They allow each injector nozzle to be triggered independently, resulting in higher fuel efficiency and lower emissions.

Direct Fuel Injection Systems

Cleaning engine injectors. Car repair.Direct systems inject fuel directly into the combustion chamber of the engine, bypassing the cylinders and valves. They have the most precise fuel metering capabilities.
