Maintaining Your Diesel in Denver

Diesel engines have been used extensively in Europe and Asia for many years. They haven’t been as common in Denver because of the high sulfur content in our diesel fuel. But the government is now mandating lower sulfur content and, as a result, we are going to see more Greenwood Village car owners driving diesel-fueled vehicles on the road, especially in passenger cars and SUV’s. Diesels are popular because they get better fuel efficiency than gas-powered engines. They also last longer. Modern diesel engines are quiet and powerful. If you still associate diesel engines with black smoke, then you’re not up with the times; that smoke is a thing of the past. Diesels don’t produce any more pollutants than gasoline engines. The pollution standards for diesel-powered vehicles are as strict in Colorado as for other vehicles. Also, diesel engines can run on bio-diesel fuels as well as fossil fuels. Diesel fuel can be produced from vegeta ... read more

Fuel System Cleaning at Davis Repair for Better Performance

Hi Centennial auto owners. 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 the engine. Fuel injectors are engineered to spray fuel in a specific pattern into the engine. (The pattern varies by engine type and design.) In order to achieve these spray patterns, the fuel must be pressurized. The pressure in a fuel injection system varies depending on its type. Many gasoline truck engines use port injection systems, which operate with a pressure of 60 pounds per square inch. Newer direct injection systems operate at 10 to 30 times that pressure. Some diesel passenger vehicles have fuel injectors that operate at 30,000 pounds or more per square inch. Vehicles have one fuel injector for each cylinder in the engine. Your vehicle’s cont ... read more

E-85 Fuel Safety Advice

Today at Davis Repair we want to talk with you about a very important safety issue. This automotive safety warning is coming from a very unusual source: fire fighting experts. You’ve probably heard of E-85 gasoline being offered in the Denver area. Some newer vehicle models are specifically built to run on E-85 – the rest are not. E-85 gasoline has been developed to fight air pollution and reduce oil consumption. E-85 fuel is a mix of 85% ethanol, a grain-base alcohol, and 15% gasoline. So-called Flex-Fuel vehicles are designed to use either normal gasoline or E-85 gas. The result is lower harmful exhaust emissions to our local Denver community. All gas engines can run with up to 10% ethanol and in fact a lot of gasoline sold in the Centennial Colorado area does contain some ethanol. The problem comes when well meaning people without Flex Fuel certified vehicles put E-85 into the tank. At a 15% concentration, the potentia ... read more
