You know that the idea behind an engine is to burn gasoline to create pressure, and then to turn the pressure into motion. A remarkably tiny amount of gasoline is needed during each combustion cycle. Something on the order of 10 milligrams of gasoline per combustion stroke is all it takes!
The goal of a carburetor is to mix just the right amount of gasoline with air so that the engine runs properly. If there is not enough fuel mixed with the air, the engine "runs lean" and either will not run or potentially damages the engine. If there is too much fuel mixed with the air, the engine "runs rich" and either will not run (it floods), runs very smoky, runs poorly (bogs down, stalls easily), or at the very least wastes fuel. The carb is in charge of getting the mixture just right.
The intake system on a four-stroke car engine has one main goal, to get as much air-fuel mixture into the cylinder as possible. One way to help the intake is by tuning the lengths of the pipes.
When the intake valve is open on the engine, air is being sucked into the engine, so the air in the intake runner is moving rapidly toward the cylinder. When the intake valve closes suddenly, this air slams to a stop and stacks up on itself, forming an area of high pressure. This high-pressure wave makes its way up the intake runner away from the cylinder. When it reaches the end of the intake runner, where the runner connects to the intake manifold, the pressure wave bounces back down the intake runner.
Whether it is a fuel line replacement or wiring a battery isolator, you can accomplish many seemingly tough jobs on your own. If you find yourself in need of a battery isolator wiring, here are a few tools and materials needed, as well as steps that can help to guide you. Step 1 - Turn Everything Off and Prepare
Begin by making sure that the car is turned off. This is an extremely important step so that you do not do any damage to the car and more importantly, to yourself. Then, allow the car to cool completely for about 20 minutes or so, especially if you were just out driving. You do not want to be working in it and then burn yourself or cause any electrical damage. Then, once the car is ready to be worked on, you will want to check out the manual just to familiarize yourself with everything that is going on so you know where to look.
Every 3 to 5 years, radiator hose clamps and radiator hoses should be replaced so that the engine is in proper working order. With age and use they can become brittle, swollen, or corroded. The radiator can only cool the car if the internal pressure stays high. If the hose clamps become faulty or are improperly installed, the internal engine pressure will drop, and the car will overheat. Be sure you are careful when installing a new radiator hose clamp. Luckily, this is an easy task which should only take about half an hour.
