Intake valve sucks in air while fuel is delivered by the injectors.

If the ignition timing is the problem, it isn’t as easy to notice because it has four cycles: If the engine timing of the cam is off, your car will either be running rough or not at all. The other scenario, the more expensive result would be engine need replacing. So, if that part of the engine timing is off, the two can hit each other, which would likely result in the engine needing to be rebuilt if you’re lucky. Because the engine pistons and valves fill the same space in the engine cylinder, but with different timing, the intervals between the timing of the two occupying that space is less than one second, aka, the engine timing. There are “interference engines,” like those in BMWs, and the consequences of bad timing can be notably bad. The engine of your BMW can be damaged by timing that is off. The pistons and valves are regulated by the cam timing, which is controlled by the engine timing belt. There are two types of engine timing: cam timing and ignition timing. Each of these things have to work in perfect coordination for the engine timing to be in sync and run correctly and smoothly. As the crankshaft spin, the connecting rods pull and push. The engine valves correspond with the pistons as they move up and down. Each of these parts are important to the engine timing, such as the camshaft, crankshaft, engine timing belt, engine valves, pistons, pulleys, and rod being the main ones that keep your BMW running as it should. There are many components and parts to a car engine, many of them are rapidly moving to keep the car running. This is especially true for a German made car like the BMW. When the engine timing isn’t right on car, it can affect how it runs, drives, the gas mileage, and more. Timing is everything, especially when it comes to how well your car is running.
