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 …

Directional signals and fog lights make it easier for you to see and be seen; overhead lights, map lights, lit glove compartments, and illuminated mirrors on sun visors all require attention periodically. In this section, I deal primarily with headlights and modern headlamps. If you experience problems with other lights, …

If you managed to goof up your headlight adjusting screws, or if you just aren’t sure whether your headlights are properly aligned, you can perform a simple check. When you’re driving on a fairly straight road at night, see if your headlights appear to be shining straight ahead and are …

In order to discuss the theory behind camshaft profiles, one should first have some understanding of the different types of scams that exist. The major types of cams are roller and flat tappet cams. Flat tappet cams incorporate a lifter that has a flat face that rides on the cam …

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 …

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 …

An intake manifold is comprised of the main trunk that diverges into separate passages leading to the individual intake valves for each cylinder, which routes the incoming air from the throttle body or carburetor to the cylinder head. The basic intake manifold will be designed for minimum resistance to airflow, …

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 …

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 …

Introduction All vehicle fuel systems consist of the carburettor or fuel injectors, the fuel tank, the fuel pump and the fuel f lter, together with connecting pipes. An engine works by the massive expansion of an ignited fuel air mixture acting on a piston. The job of the fuel system …
