Keeping Your Fuel System in Tune

Fuel system problems may occur for a variety of reasons. Some remedies, such as replacing a fuel filter, are relatively inexpensive. Others, such as replacing a fuel pump, are costly.

Leave your distributor to a pro

Require no regular servicing. Some have no distributors at all. All testing and servicing of these systems should be left to trained professionals because they’re easily damaged if hooked up improperly, and they employ high voltage that can also damage you. If you’re curious, explain what distributors do. Replacing a …

The following Fuel through the Fuel Injectors

Just about every new vehicle is fuel-injected. (The last carbureted vehicles came off the assembly line in 1990.) Although they’re more expensive to service than carburetors were, fuel injection systems with computerized electronic sensing devices have shown sufficient sensitivity, accuracy, and dependability to repay their cost with better performance, greater …

Improvements to fuel injection systems

Two exciting ways that fuel injection systems are being perfected is the replacement of moving parts with stationary ones and solid parts with intangible substances. By reducing the number of mechanical parts, car manufacturers hope to reduce production costs and create devices that are less susceptible to breakdown due to …

Turbocharger-related Sources of Engine Failure

The damage that may occur from a turbocharger usually concerns pre-ignition or ”engine knock.” This sometimes occurs from setting the timing of the spark ignition system at a value that is too far advanced. The combination of increased cylinder pressure and early ignition causes combustion substantially before the piston has …

Turbocharging Turbocharger Efficiency

When matched properly to an appropriate internal combustion engine, turbochargers provide a great means to efficiently increase the power output of any engine. Naturally aspirated engines are limited to the amount of air/fuel charge that can be combusted efficiently. The amount of air that makes its way to the combustion …
