Bosch Fuel Injectors

What are Bosch fuel injectors?

Bosch fuel injectors, also called Bosch common rail fuel injectors, are devices for atomizing and and injecting fuel into an internal combustion engine, which are specially used on auto engines. It was also called the racing fuel injectors and the fast fuel injectors.


What is the application of Bosch fuel injectors?

Bosch fuel injectors have widely applications on vehicles and diesel passenger cars, SUVs, van and pick up trucks:

Ashok Leyland, Audi, BharatBenz, Force Motors (Bajaj Tempo), BMW, Chevrolet, Dacia, Eicher, Fiat, Ford, Honda, Hyundai, Isuzu, Jaguar, Jeep, Land Rover Group, Man, Mercedes-Benz, Mini (BMW), M&M, Maruti, Nissan, Porsche, Renault, Skoda, Suzuki, Swaraj Mazda, Tata (Telco), Toyota, Volvo.

What are the differences between Bosch Fuel Injectors and others?

  1. More fuel-efficient with lower emissions. 

 Fuel injectors use gasoline much more efficiently since it goes directly into the combustion chamber and atomizes in a homogeneous dispersion. The result is more complete combustion, resulting in better fuel efficiency and less pollution.

  1. Better for cold startups. 

 When the engine is not warm, the fuel doesn't vaporize as quickly. In carburetors, this is managed by adjusting the choke for a richer fuel mixture. By putting fuel directly into the combustion chamber under pressure, fuel injection overcomes this problem that dogs carbureted engines during a cold start. No longer was it necessary to crank the starter over while pumping the gas pedal to get going on a cold winter morning!

  1. Cooling properties. 

 Direct fuel injection has the benefit of putting liquid fuel into the cylinders, which immediately vaporizes and has a cooling effect on the cylinders, similar to how a squirt from a spray bottle on a hot summer day is refreshing.

  1. More stable but more complex.

 The air/fuel ratio is more precise with fuel injection than carburation. However, the system uses a high-pressure fuel pump and fine jets, which add complex and expensive parts, even more so with modern fuel injectors that are controlled electronically via ECUs and have oxygen sensors to calibrate the air/fuel ratio.
