How an Engine Works
Автокөліктер мен көлік құралдары
Here's how a car engine works to power your car!
The internal combustion engine converts gasoline fuel into rotational energy used by your car's transmission to power the wheels. Most vehicles situate the engine at the front of the vehicle and come in various configurations such as the "inline" "Boxer" and "V" cylinder arrangements.
In this video, a 3.5L VQ35DE Nissan Infiniti V6 engine from an Infiniti G35 is stripped down and taken apart piece by piece to explain what's inside and how it works. There are 5 main sections to a car engine, starting at the top with the valve covers, the engine head (with camshafts), the engine block (with pistons) the crank case (with crankshaft) and the oil pan. Here's a video on how the engine was removed from the vehicle:
• How to Remove a Car En...
The fuel-air mixture begins its path from the air intake into the intake manifold. More information on the air intake can be found here:
• How an Air Intake Syst...
The air makes its way into the combustion chamber as the piston is on its down stroke. As the piston moves up, the air-fuel mixture begins to compress as the valve timing closes the intake valves. The spark plug fires creating a small explosion in the cylinder, pushing the piston down creating a clockwise torque on the crankshaft due to its offset with the connecting rod. This process is repeated six times through each cylinder and its firing order is offset to reduce vibration and smoother engine torque output.
The tear-down procedure starts with removing all the engine accessories (such as the A/C compressor, alternator, power steering pump, cooling circuits and brackets). Next, the timing cover, engine oil pan and valve cover gaskets are removed to demonstrate role of valve timing on the top half of the engine. Once the head is removed, the pistons in the "V6" arrangement can be clearly demonstrated, followed by removal of the crank case and crank shaft with bearings.
For a 4 cylinder explanation, see a Toyota Corolla 1ZZ-FE engine being torn down here:
