In a motor vehicle, the term drivetrain or powertrain refers to the group of components that generate power and deliver it to the road surface, water, or air. A motor Vehicle is a Machine which incorporates a motor (sometimes known as an Engine) and which is used for Transportation This includes the engine, transmission, driveshafts, differentials, and the final drive (drive wheels, caterpillar track, propeller, etc. The internal combustion engine is an engine in which the Combustion of Fuel and an Oxidizer (typically air occurs in a confined space called a This article deals with the concept of a differential in mechanical engineering. A drive wheel is a Wheel in an automotive Vehicle that receives power from the Powertrain, and provides the final driving force for a vehicle Continuous tracks are large (modular tracks used on the so-called caterpillar Tanks construction equipment and certain other off-road vehicles A propeller is essentially a type of fan which transmits power by converting Rotational motion into Thrust for propulsion of a vehicle such as an ). Sometimes "powertrain" is used to refer to simply the engine and transmission, including the other components only if they are integral to the transmission. In a carriage or wagon, running gear designates the wheels and axles in distinction from the body. A carriage is a wheeled vehicle for people usually horse-drawn A wagon (in British English, sometimes waggon) or dray is a heavy four-wheeled Vehicle.

A motor vehicle's driveline consists of the parts of the drivetrain excluding the engine and transmission. It is the portion of a vehicle, after the transmission, that changes depending on whether a vehicle is front-wheel drive, rear-wheel drive, or four-wheel drive. Front-wheel drive (or FF layout) is a form of engine / transmission layout used in Motor vehicles where the engine drives the front Wheels Four-wheel drive, 4WD, or 4x4 ("four by four" is a four-wheeled Vehicle with a drivetrain that allows all four Wheels to

Broader definition

In a wider sense, the power-train includes all of its components to transform chemical, physical or nuclear energy into secondary energy and deliver it to the interface to the outer world for propulsion purposes. This includes the utilization of multiple power sources and non–wheel-based vehicles.

Developments

Powertrain development for diesel engines involves the following trends: modular injection, electronic valve control (EVC), low pressure exhaust gas recirculation (EGR), and advanced combustion. A diesel engine is an Internal combustion engine which operates using the Diesel cycle (named after Dr Spark ignition technology has focused on de-throttling (in part load where the low efficiency of Otto engines is defined) and downsizing (lower displacement, EVC). The term spark-ignition engine is normally used to refer to Internal combustion engines where the fuel-air mixture is ignited with a spark. Today Internal combustion engines in cars, Trucks motorcycles aircraft construction machinery and many others most commonly use a four-stroke cycle. [1]

Attention to new fuel qualities (no sulphur and aromates) allow new combustion concepts. Sulfur or sulphur (ˈsʌlfɚ see spelling below) is the Chemical element that has the Atomic number 16 These promise to combine clean combustion with high efficiency. So-called "combined combustion systems" (CCV) (Volkswagen, 2003) or "diesotto" cycles (Mercedes-Benz) are based on synthetic fuels (synthetic diesel, biomass to liquid (BTL) or gas to liquid (GTL)). Year 2003 ( MMIII) was a Common year starting on Wednesday of the Gregorian calendar. Mercedes-Benz is a German manufacturer of luxury Automobiles Buses coaches and Trucks It is currently a division of the Biomass to liquid ( BTL) or BMTL is a (multi step process to produce liquid Biofuels from Biomass: The process uses the whole plant to improve the Gas to liquids or GTL is a refinery process to convert Natural gas or other gaseous Hydrocarbons into Longer-chain hydrocarbons [2]

Manufacturing

The manufacturing of powertrain components and systems is a key factor in the competitive position of companies in the automotive and other (truck, motorcycle, tractor, construction equipment…) vehicle industrial sectors. Global economic and environmental factors have led to the requirement to engineer and produce powertrain system that are more economical to manufacture, higher in product quality and reliability, higher in performance, more fuel efficient, less polluting, and longer in life expectancy. In turn these trends have led to designs that involve higher internal pressures, are subject to greater instantaneous forces, and are more complex in their design and mechanical operation. The resulting advanced powertrain designs in turn impose significantly more severe requirements on the shape, flatness, waviness, roughness, and porosity,of powertrain subsystems, as well as limitations on the allowed presence of potential defects in the surfaces and other dimensional characteristics of the system components and assemblies. The intuitive idea of flatness is important in several fields Roughness is a measure of the texture of a Surface. It is quantified by the vertical deviations of a real surface from its ideal form Porosity is a measure of the void spaces in a material and is measured as a fraction between 0–1 or as a Percentage between 0–100% In addition to improved materials and material forming methods, these requirements have led to advanced metrology technology that more thoroughly and accurately measures and enables improved control of all of the steps in powertrain manufacturing processes.

Frames and powertrains

The frame plus the "running gear" (powertrain) makes the chassis. A chassis (plural "chassis" (ˈʃæːsiː ˈtʃæːsiː consists of a framework that supports an inanimate object analogous to an Animal 's

Later, a body (sometimes referred to as "coachwork"), which is usually not necessary for integrity of the structure, is built on the chassis to complete the vehicle. Coachwork is the body of a Motor vehicle ( Automobile, Bus or Truck) which is built around a Chassis, rather than Vehicles, derived from the Latin word vehiculum, are non-living Means of transport. Commercial vehicle manufacturers may have “chassis only” and “cowl and chassis” versions that can be outfitted with specialized bodies. These include motor homes, fire engines , ambulances, etc. In North American English the term recreational vehicle, and its acronym RV, are generally used to refer to an enclosed piece of equipment dually used as both A fire apparatus, fire engine, fire truck, or fire appliance is a vehicle designed to assist in fighting Fires by transporting Firefighters An ambulance is a Vehicle for transporting sick or injured people to from or between places of treatment for an Illness or Injury.

The frame plus the body makes a glider (a vehicle without a drivetrain). A vehicle glider is vehicle without powertrain (specially without Engine) It is generally a brand new car but can be used also a second hand car
