The engine is the vehicle's main source of power. The engine uses fuel and burns it to produce mechanical power. Chemical Energy converted into Mechanical Energy. The heat produced by the combustion is used to create pressure which is then used to drive a mechanical device. The engine also supplies the rotational energy to drive the alternator which supplies electricity to power computers, lighting and accessories, Driving the power steering pump to give you power steering, and to run your HVAC system.
Maintenance of Drive Train
Engine, Transmission and Differential services are paramount to longevity of your vehicle. Regular inspections during an oil change can save thousands of dollars in the long term. Addressing leaks of engine oil and coolant will allow your engine to last much longer and will avoid breakdowns. Changing transmission fluid every 50,000 miles will help with longevity and fuel economy. Changing differential fluids according to manufacturers specs will also allow the differentials to perform for a longer period of time.
The transmission's primary job is to allow the engine to operate in a range of RPM suitable to the engines design while providing a range of output speeds. The transmission uses gears to make effective use of the engine's torque, and to keep the engine operating at an RPM designed to promote fuel economy and power. The transmission supplies torque through a drive shaft or differential to the tires to provide propulsion.
