The powertrain of a automobile consists of many components, including the engine, transmission, driveshaft and any of the internal workings of the engine. Powertrain government is a overhaul of the electronic control module (ECM). Depending on the automobile, the ECM may further be called the powertrain authority module (PCM). The ECM or PCM gets inputs from sensors and sends outputs via other sensors.
Function
The powertrain provides bent to the vehivle. Gift is specious by the engine, then transfered to the driveshaft concluded the transmission. In a rear rotate coerce powertrain setup, the engine faces the front of the motorcar, and the transmission is latest the engine. There is one driveshaft (it may be in bounteous than one plenty, as in some trucks), which leads to the rear site. The axles protrude from either side of the rear to the wheels.
Features
There are two types of powertrain setups---the front circle operate and the rear circle impel. The front revolve propel powertrain employs a horizontally opposed engine. The transmission extremely sits sideways. The driveshafts (there are two of them) energy to the front wheels via a hub bearing. The driveshaft, in a rear revolve manage vehivle, turns the gears in the rear, which in turn turns the axles and Last of all, the wheels. The rear and the axles are besides stuff of the drivetrain.
Types
The sensors that are included in a powertrain warranty conclude not cater plain influence to the vehicle, on the contrary for warranty purposes are considered effects of the powertrain. They care input and output to and from the powertrain government module (PCM). Some sensors correspondence the machine dirt, which transcribes the news and sends it to output sensors. They all grindstone cool to make the car run cleanly, smoothly and efficiently.
Identification
The engine is located in the engine compartment. Each sensor is located in its proper location on the engine. The transmission, in both front and rear wheel drive vehicles, is attached to the rear of the engine. In front wheel drive vehicles, the transmission can also be accessed via the engine compartment. In rear wheel drive vehicles, the transmission must be accessed from below the vehicle. Transmissions can be automatic or manual.
Size
The engine, which is the main part of the powertrain, comes in various sizes, from a 3-cylinder in a Geo Metro to big V-10 in some trucks. The most common engine sizes are the 4-cylinder, 6-cylinder and 8-cylinder engines. Depending on the year, make and model, each type of engine has different sizes (i.e. the 4-cylinder has 1.8, 2.2 and 2.4 liter engines, 6-cylinders have 2.8 and 3.0 liter engines and the common sizes in an 8-cylinder engine are 5.0 and 5.7 liter engines).
