Grand Rapids motorists know that engines burn fuel to operate. Fuel is pumped from your fuel tank to your engine where it is squirted—or injected—into your engine’s cylinders. This is the function of the fuel injectors.
There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with air and before it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the engine.
Direct injection engines burn fuel more efficiently than conventional engines. Some models can deliver the power of a V8 with the economy of a V6.
For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same fuel efficiency. The turbocharged version delivers 350 horsepower.
Why the big difference in power? Direct injection systems allow fuel to be squirted into the engine at hundreds of times the pressure of a conventional engine. This atomizes the fuel better (breaks it down into tinier droplets), which means more of it gets burned, which translates to more power for your engine. It also results in cleaner emissions and improved fuel efficiency.
Fuel injectors are precision instruments. They have to deliver the right amount of fuel at exactly the time the engine needs it. They are also engineered to inject fuel with a specific spray pattern. This spray pattern allows for maximum fuel efficiency and proper atomization.
Direct injection engines require a much higher degree of precision than conventional engines. For this reason, they are equipped with more sophisticated computers.
When fuel injectors get dirty, their precision drops off. The spray pattern won’t be precise, and the timing of fuel delivery may be off. This decreases fuel efficiency and gas mileage for Grand Rapids drivers as well as delivering less power to the engine.
Fuel injectors are not cheap to replace. Direct injection fuel injectors are even more expensive. And we’re talking a mortgage payment to buy a set of new fuel injectors for a diesel engine.
So keeping your fuel injectors clean is just good auto advice for Grand Rapids auto owners. The best way to do this is to change your air and fuel filters regularly and practice other habits of good car care and preventive maintenance at Ervine’s Auto Repair in Grand Rapids. Cleaning additives in your fuel can also help.
If you do end up with gum or varnish in your fuel system, you’ll need a professional fuel system cleaning. This will clean out your whole system, including the injectors. The good news is that with proper maintenance, your fuel injectors will last for a long time.
Chelsea Vives: Awesome service!! They were extremely helpful and friendly! I loved how they were accommodating to the customers and being very organized with after hours drop-offs and pick-ups. They were also very quick with fixing my car which was great.
Andy Krafft: Ervine's has provided great service for me throughout my college years! They do their best to make time for customers and understand the importance and value in quality service. Would definitely recommend!
Erin O'Brien-Jenison: The staff is very friendly. The technicians take the time to explain repairs in detail. The loaner car service is very convenient for my family. Each of my experiences with Ervine's has been very positive.
Jamie Riehle: My car needed a lot of work and being relatively new to the area, I had to rely on online reviews. Ervine's got great feedback, so I made an appointment through their website. I was contacted almost immediately and scheduled very quickly. The repairs took a few days, but with the free loaner it was no big deal. They explained everything to me, helped me prioritize which repairs to do first, and Jamie even entertained my 5-year-old while I spent 10 minutes on the phone with my bank to get my payment to go through. I may have been able to find someplace a little cheaper, but you can't pay for the excellent customer service at Ervine's. The lobby is clean, has fresh coffee, and is very professional. As a woman I've been intimidated going into car shops but I never felt that way at Ervine's. I'll definitely be returning.
Kaitlin McDowell: I had a great experience at Ervine's. I know very little about my car beyond turning it on, so I was relieved when the staff were willing to spend extra time explaining to me exactly what is going on and helping me to be an informed consumer. I also appreciated that they are not trying to sell something-- I did not actually need the repair that the dealership had told me to IMMEDIATELY deal with, and the folks at Ervine's were willing to tell me that when they could have made a buck doing the repair. The visit was so painless I even got to run errands while I was waiting using one of their fabulous loaner cars. Thank you so much!
