![]() ![]() The next stage is power, and it is when the explosion of gasoline forcefully pushes the piston back down to rotate the engine. The air is fully compressed when the piston is as high as possible, and this is called “top dead center.” This is the ideal time for the spark plug to fire. The pressure is necessary to get a nice explosion instead of a slow burn, and this is the key to getting propulsion out of the process. The compression stage is when the piston applies pressure to the air-fuel mixture. Those strokes are called intake, compression, power and exhaust.ĭuring intake, air and fuel are drawn into the cylinder for combustion. To keep an engine running, it undergoes four steps (called strokes) in rapid succession. If this is a little hazy, it’ll make more sense when we talk about the whole engine cycle. More specifically, we want to fire the plug right before the piston reaches its peak in the up-and-down motion. To ignite the gasoline, we use electric spark plugs, so when we refer to a vehicle’s timing, we’re talking about making sure the spark plug fires at the best possible moment. This is ignoring a lot of other processes that happen at the same time, but it’s the primary function of your engine. That motion spins the engine which in turn rotates the gears and spins the wheels. To put it simply, an engine works by using small explosions of gasoline to make pistons move up and down. ![]() What Is Timing?īefore we learn how to set ignition timing, we require a short lesson on how engines work. In those cases, an scan tool would be a better investment. Most manufactured since the early 90s will have an electronic ignition timing and do not require this maintenance. Before you jump in, double check your vehicle. While you can get a mechanic to adjust the timing for you, it’s a fairly easy process with a quality timing light, and you’ll stand to save a lot of money when you learn to do it yourself. When timing is neglected, you can suffer poor gas mileage, less power when you hit the gas and eventually degrading problems that might keep the engine from running. Actron scan tools and code readers are made compatible with all 1996 and newer import and domestic vehicles (OBD II & CAN) as well as ‘94 and ‘95 OBD II-compliant vehicles.You need to adjust timing on a car for many older models (those which have a distributor) to maintain the best possible performance. It helps customers save time and money during vehicle repair. The same is true with its automotive diagnostic equipment. The company’s scan tools and code readers are designed to diagnose any vehicle quickly and accurately to they can get fixed in no time. Actron products allow customers to work less and live more.
