What are Direct Injection Engines and How Does it Affect My Car?

WARNING: If your vehicle has a direct injection engine it’s critical that you read this article and you NEED to be scheduling induction services at the right mileage intervals, or in time, it can cause very expensive repairs. Induction services are just as important as oil changes and other routine maintenance.

Direct injection engines have a fuel delivery system that is becoming increasingly popular in modern vehicles.

It offers several benefits over traditional fuel injection systems, including improved fuel efficiency and performance. However, one downside of direct injection engines is that it can lead to a build-up of carbon deposits in the engine. This is because the fuel injector is spraying directly into the combustion chamber instead of spraying the back of the intake valve as is the case with a standard port fuel injected system. The carbon build up can cause reduced engine performance, running issues, and lower fuel economy, which leads to you to spend more money at the gas pump. This is where an induction service comes in.

So, what is an induction service and why is it critical for vehicles with direct injection?

An induction service is a process that involves cleaning the intake system, including the intake manifold, throttle body, and combustion chamber, to remove carbon deposits. A fuel system additive is included in the kit to prevent carbon build up. These deposits can build up over time and can cause a variety of issues, including reduced engine performance, reduced fuel efficiency, and running issues.

There are a few different methods that can be used to perform an induction service.

One method involves using specialized cleaning chemicals from our partners at BG that are introduced into the intake system through the intake manifold. These chemicals help to break down and remove the carbon deposits. Another method, which isn’t as effective, involves using a machine that uses high pressure air and/or cleaning solution to blast away the carbon deposits and another involves “walnut blasting” which is very invasive and expensive.

Regardless of the method used, an induction service is a relatively quick and easy process that can have a significant impact on the performance of your vehicle.

In addition to improving engine performance and fuel efficiency, an induction service can also help to extend the life of your engine by preventing damage caused by carbon deposits.

So, how often should you have an induction service?

The answer to this question depends on a few factors, including the age and make of your vehicle, as well as your driving habits. In general, it is recommended to have an induction service every 30,000 to 50,000 miles or every 2 to 4 years, whichever comes first. If you drive in extreme conditions (such as very hot or cold temperatures, or if you do a lot of stop-and-go driving), you may need to have an induction service more frequently.

It’s also a good idea to consult your owner’s manual and/or a trusted mechanic for the specific recommendation for your vehicle. Some automakers have included an induction service as part of their recommended maintenance schedule, while others do not.

Conclusion

An induction service is a critical maintenance task for vehicles with direct injection. It helps to improve engine performance, fuel efficiency, and can extend the life of your engine by preventing damage caused by carbon deposits. Doing an induction service now will save you money and heartache at the gas pump, and help you avoid major repairs in the future.
