How's This Work? Direct Injection

How's This Work? Direct Injection

What is Direct Injection?

For this week’s How’s This Work, we thought we’d switch back to a feature that’s available from a multitude of different manufacturers as it’s a technology found in engines. Many of the engines available in our Honda vehicles utilize Direct Injection, as it’s a pretty big part of Earth Dreams Technology. But we figured we’d dive into what exactly it is and how it works.

[ LAST WEEK: What is Eco Assist? ]

How does Direct Injection work?

There are a few different ways for fuel to be introduced to the engine of your vehicle, and conventionally vehicles utilize something called a multi-point fuel injection method. The multi-point method injects fuel into something called the intake track or cylinder port, rather than injecting it into the engine. With that explanation in mind, you might be able to figure out how direct injection differs from the multi-point method.

Rather than utilizing intake tracks or cylinder ports, the Direct Injection system injects fuel directly into the combustion chamber utilizing a high pressure method. While this doesn’t change anything drastically, there are a few benefits of direct injection in comparison to other methods like multi-point. It has been proven that many engines with direct injection equipped have enabled a stratified fuel charge or ultra-lean burn within the combustion chamber, which ultimately means your fuel efficiency will be improved while your emission levels are reduced.

Needless to say, these are both pretty important things to most drivers on the road today. Today, 45% of vehicles have direct injection installed, which is up from the 2.3% of vehicles that utilized it nearly a decade ago. We expect direct injection to continue its rise to prominence, until of course the next new technology is introduced. If you’re interested in finding out which of our vehicles come with direct injection installed just give us a call right here at the service desk. You can watch the video below for a more visual look at direct injection and other engine technologies.
