For those of you in Westerville, Ohio who pay attention to these things, you may have been hearing about the new direct injection engines and want to learn more about them. Some deliver the power of a V8 with the economy of a V6.
For example, in one family of engines the conventional V6 makes about 250 horsepower. The direct injection version of the same engine makes over 300 horsepower and gets essentially the same fuel economy. The turbocharged version makes over 350 horsepower.
So what are the differences from a conventional engine?
The core difference is in the fuel injection system. The system most vehicles use now is called a port injection system. The fuel injector squirts fuel into a port just outside the cylinder where it's then drawn into the engine with the air.
With a direct injection system, the injector squirts the fuel directly into the cylinder. The gain in power and economy come because fuel injected directly into the cylinder during the combustion cycle is burned much more efficiently.
First, the fuel is squirted in at hundreds of times more pressure, so it's atomized much better and burns cleaner and stronger. The other big advance is in electronics. Faster engine management computers can control the additional precision required to manage direct fuel injection.
Fuel injectors are precision instruments. They have to deliver a precise amount of fuel at exactly the right time. The design of the engine also dictates a particular spray pattern for the fuel. If a fuel injector is dirty or gummed up, it can't do its job as well. That means less power and worse fuel economy for your vehicle and can lead to damaged fuel injectors.
Replacing fuel injectors at Tuffy Tire & Auto Service Westerville isn't cheap. Direct injection injectors are even more expensive because of the extremely high-pressure they use. Same thing for diesel fuel injectors; we're talking mortgage payment-range to replace a set of diesel injectors.
A professional fuel system cleaning from Tuffy Tire & Auto Service Westerville gets out the gum and varnish in the whole system, including the fuel injectors. Keep those injectors clean and they'll last a long, long time.

When you get in your vehicle, how does it smell? If it's not so nice, it may be time to have your cabin air filter changed. It's not the same one that filters out the air used in the engine. The cabin air filter screens out dust and other particulates from the outside air so when it enters the c... More

Hi Westerville residents. Let's talk fuel injectors. A fuel injector is a valve that delivers fuel to a vehicle's engine. It has to deliver the precise amount of fuel to precisely the right place, precisely when the engine needs it. The fuel also has to be mixed with air before it can burn in th... More

You're heading down the road and you notice your vehicle is sputtering, like it's running out of gas. But the gauge show's it's still got a quarter of a tank. So what gives? It could be that your fuel pump is failing, meaning your engine is not getting enough gas to run properly. While fuel pu... More
