Working Principle of Fuel Injection System For the engine to run smoothly and efficiently it needs to be provided with the right quantity of fuel/air mixture according to its wide range of demands. Traditionally, the fuel/air mixture is controlled by the carburettor, an instrument that is by no means perfect. Its major disadvantage is that a single carburettor supplying a four-cylinder engine cannot give each cylinder precisely the same fuel/air mixture because some of the cylinders are further away from the carburettor than others. One solution is to fit twin-carburettors, but these are difficult to tune correctly. Instead, many cars are now being fitted with fuel-injected engines where the fuel is delivered in precise bursts. Engines so equipped are usually more efficient and more powerful than carburetted ones, and they can also be more economical, as well as having less poisonous emissions.

Step 1 Run your engine. Since warm oil drains faster than cold, run your engine for only a couple of minutes. You never want to get your engine up to full operating temperature, because the oil will be way too hot to safely drain. Step 2 Drive your car onto two ramps. Apply the parking brake. Remove the key. Place chucks behind the wheels for safety. Put on your safety glasses and gloves. Step 3 Locate the oil drain plug and place the oil pan below it. Consult your owner ’ s service manual for help in locating the oil drain plug, and remember that the oil will flow at an angle into the pan. Loosen the plug with a socket wrench. Step 4 Unscrew the plug by hand. While unscrewing it, push the plug back toward the pan to keep oil from rushing out until you are ready to remove the plug from the hole. Be careful — that oil may be hot! Step 5 Drain old oil. Check your owner ’ s service manual to find the location of the filler cap on top of your eng...

The oil tank, constructed of welded aluminum, is serviced (filled) through a filler neck located on the tank and equipped with a spring-loaded locking cap. Inside the tank, a weighted, flexible rubber oil hose is mounted so that it is repositioned automatically to ensure oil pickup during all maneuvers. A dipstick guard is welded inside the tank for the protection of the flexible oil hose assembly. During normal flight, the oil tank is vented to the engine crankcase by a flexible line at the top of the tank. The location of the oil system components in relation to each other and to the engine is shown in Figure 6-18. Repair of an oil tank usually requires that the tank be removed. The removal and installation procedures normally remain the same regardless of whether the engine is removed or not. First, the oil must be drained. Most light aircraft provide an oil drain similar to that shown in Figure 6-19. On some aircraft, the normal ground attitude of the aircraft may prevent t...

The most labor-intensive seal to replace on any engine is the rear main seal. There are no shortcuts or quick fixes if the seal has expired. On most modern engines, the seal ’ s failure is due to a condition inside the engine or a component connected to the back of the engine. PTFE Rear Main Seal Solving why the seal failed in the first place is critical to preventing a labor-intensive comeback. Here are six questions you should be asking yourself before, during and after a rear main seal  job. Is it the rear main seal that is leaking? It might not be. On most engines, oil leaks can occur above and below the rear main seal. It could be a leaking oil pressure sensor, oil pan gasket or galley plug near the seal that causes oil to come from the bell housing. Adding dye to the oil can help reveal where the oil is coming from. Is the PCV system clogged or blocked? Most rear main seals have a lip that rides on the shaft. The pressure inside the crankcase will push...
