ABOUT US: Weber State University (WSU) - Automotive Technology Department - Transmission Lab. This video demonstrates the operation of a typical manual transmission. See the parts of a manual transmission in operation. The information here applies to most manual transmissions and transaxles. This particular transmission is a 1995 Toyota "Truck" 5-speed Aisin R150 model. A version of this same transmission is used in some newer vehicles today. We teach current vehicle technologies to our automotive students at Weber State University and online.

A3.C.4 "Diagnose hard shifting and jumping out of gear concerns; determine necessary action.", a priority 2 task. This video was created and edited by Professor John D. Kelly at WSU.

In this simple video we will explain all the steps involved in this process, from the ignition to the operation of the internal combustion engine. When you get on your car the first thing you do, after putting the seat belts on, is to insert the key in the ignition switch to start the engine. When the switch is turned on, the electric circuit between the battery and the starter motor is closed. The starter motor is an important element for the starting system. It allows the engine to reach the proper rpm so as to initiate the engine's operation under its own power. The starter motor essentially transforms the electrical energy into mechanical energy. The starter motor is coupled to the FLYWHEEL, which in turn provides to transmit the motion to the CRANKSHAFT. Now the combustion cycle takes place inside the engine cylinders, so the starter motor is disconnected. Now let's see what happens inside the engine, taking the example of a common 4-STROKE ENGINE. A four-stroke engine is an internal combustion engine widely used in cars. It represents an example of efficiency and perfect synchronization. It converts the explosions that occur inside its combustion chambers into motion. The 4-stroke engine in fact gains its energy from heat released during the combustion of the air and fuel mixture inside its cylinders. The aim of this engine is to use this energy to provide movement and transfer it to the wheels, so that the vehicle can move. This process requires only 4 simple steps: It all takes place inside the cylinder. Here we can find the combustion chamber where the explosions occur. The cylinder is basically the space through which the piston travels. The purpose of the piston is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod or a connecting rod, so that the back-and-forth linear motion of the pistons is transformed into a circular motion which can power the wheels. But let's see this process more in detail by disassembling the engine. 02.34 This process requires only 4 simple steps: It all takes place inside the cylinder. Here we can find the combustion chamber where the explosions occur. The cylinder is basically the space through which the piston travels. The purpose of the piston is to transfer force from expanding gas in the cylinder to the crankshaft The term “four-stroke” is reffered to the cycle of engine operation which requires 4 strokes of the piston: First stroke: INTAKE: The valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure through its downward motion. The air and fuel were previously mixed together by the injectors. The air-fuel ratio is generally about 14.7 to 1. That’s becouse fuel cannot ignite alone. It is the oxygen in the air in fact that provides the combustion of the fuel. What happens now that the air-fuel mixture is iniside the cylinder? Second stroke: COMPRESSION: During this stage both the intake and exhaust valves are closed, and the piston moves up the chamber to the top. This cause the compression of the fuel-air mixture which decreases 10 times its volume. At this point pressure rises drastically as the air and fuel molecules are compressed together colliding with eachother and increasing the temperature. Now we are ready for the explosion! Third stroke: COMBUSTION and EXPANSION: At the top of the compression stroke, the SPARK PLUG fires, igniting the compressed air-fuel mixture. This causes an explosion! As the fuel burns it expands, increasing the pressure inside the cylinder and driving the piston downward moving the twist that rotates the crankshaft, which will convert the energy of the explosion into rotary motion. Now, let’s see the fourth and final stroke, which is called: EXHAUST. During the exhaust stroke, the piston, once again, returns to the top while the exhaust valve is open. This action expels the spent air-fuel mixture through the exhaust valve. The 4-stroke cycle is complete but it does not stop here. At a speed of 6000 rpm it repeats up to 50 times per second, causing 200 explosions per second inside each cylinder of this 4-stroke engine.

Simply put, a drivetrain is a series of parts in your car that work together to make your wheels turn. A powertrain, on the other hand, is basically a drivetrain plus the engine and some other parts, 1) Front-Wheel Drive (FWD): Front-wheel drive refers to a car where the transmission sends the engine’s power to the front wheels. Rear-wheel drive is the transmission that sends the engine’s power to the rear wheels. Four-and all-wheel drive cars have power at all four corners. If a vehicle features front-wheel drive, the transmission transfers power from the engine to the front wheels. The majority of cars today have a front-wheel-drive layout. This setup transfers power to the front wheels, allowing them to move and steer the vehicle. 2) Rear Wheel Drive (RWD): Rear-wheel drive is basically the opposite of FRONT-wheel drive. This drive is most commonly found on sports cars and performance sedans. Vehicles that feature rear-wheel drive are a bit more complicated. Vehicles handle much better than front-wheel drive vehicles, and you will notice the difference in curves, turns, and when navigating through traffic situations. 3) 4-Wheel Drive (4WD): Four-wheel drive, often abbreviated as 4WD, 4WD means the power from the engine is delivered to all 4 wheels all of the time when Four-by-Fours(4x4) is engaged. The 4WD vehicles are usually equipped with a transfer case which allows the car to change to RWD transmission to save fuel and get back to 4WD mode if and when required. 4) All Wheel Drive (AWD): An all-wheel-drive arrangement works on the same principle as 4WD, but in most front-wheel drive or rear-wheel drive is the primary drive mode. The general misconception is that AWD and 4×4 are the same things. While both have all 4 wheels running and run on the same principles, some key differences set the two apart. ---- Time Stamp --- 00:00 - Intro 00:25 - What are Drivetrain & Powertrain? 01:04 - Types of Drivetrains 01:49 - What is Front Wheel Drive (FWD)? 02:24 - How does FWD Works? 03:21 - Pros & Cons of FWD 04:48 - What is Rear Wheel Drive (RWD)? 05:30 - How does RWD Works? 07:35 - Pros & Cons of RWD 07:58 - What is 4 Wheel Drive (4WD)? 08:56 - How does 4WD work? 11:25 - Should you buy a 4WD Vehicle? 12:05 - Pros & Cons of 4WD 11:25 - What is All-Wheel Drive? 13:11 - How does AWD Works? 14:38 - Pros & Cons of AWD 15:59 - Which is better? 16:53 - Wrap Up Disclaimer: This video is just for educational purposes only.
