This year my knowledge of motor vehicles has increased significantly. Some parts I didn't even know existed in vehicles I now know to some extent. So far this year we have learned the theory of the compression testing engine, we have also learned what each tool is and how to use it correctly. And that lubrication is huge in vehicles because without engine lubrication there's a chance the engine will seize up or explode. We also learned that if you don't reassemble your engines correctly due to lack of knowledge or simply putting the wrong bolt somewhere, it can really ruin your day. Every engine part needs to be precise with measurements if you are even off my .0001mm you could ruin your engine. Say no to plagiarism.

The carburetor's job is to provide a mixture of air and fuel that will burn. During the suction stroke. The intake valve between the carburetor and the combustion chamber opens. This allows pressure to force the air-fuel mixture into the cylinder bore as the piston moves downward. Immediately after the piston moves to the bottom of its stroke from bottom dead center, the cylinder bore contains the maximum possible air-fuel mixture. The intake valve closes and the piston moves up the cylinder bore. This is called compression stroke. The air-fuel mixture is pressed between the piston and the cylinder head. The third step of the 4 cycles is when the piston reaches the maximum limit of its travel, called top dead center, it will be in the perfect place to ignite the fuel and get more power for your electrical equipment. High voltage is created in the ignition coil. In spark plugs, this high voltage must be exerted into the combustion chamber. The heat produced by the spark ignites the gases creating rapidly exploding superheated gases that push the piston back into the cylinder barrel. This is the power shot. When the piston reaches BDC again, the exhaust valve opens. As the piston moves up the cylinder bore, it pushes spent combustion gases through the exhaust valve and out of the exhaust systems. When the piston returns to TDC, the exhaust valve closes and the intake valve opens and the process repeats. Each time the cycle repeats, the cycle requires two full rotations of the crankshaft, while the engine creates power only during one of the strokes. To keep the car running you need the engine's small flywheel. The power stroke creates momentum that forces the flywheel to maintain momentum and the crankshaft to spin throughout the 4 strokes. These are the 4 basic steps for the 4-stroke cycle engine that I have learned so far this year. But there is much more to learn about lubrication systems, such as the difference between the lubrication system for 2-stroke engines and for 4-stroke engines. To start I will talk about 2 stroke engine components and what is called a mist lubrication system which is mostly only used for 2 stroke engines. In the 2-stroke engine, the intake and exhaust ports are opened and closed as the piston moves. There are no poppet valves while a four-stroke has poppet valves. The difference in the induction method occurs in two different ways: First, the air-fuel mixture is drawn into the crankcase as the pistons move down. It is then moved from the crankcase onto the piston. During compression, the air-fuel mixture.
