Built-in motor
The built-in engine is a term from vehicle technology and, more generally, from mechanical engineering . It is used to describe an internal combustion or electric motor that is not developed and built by the manufacturer of the machine or vehicle to equip a machine or a vehicle, but is purchased from another manufacturer or sub- supplier and then built into its own product.
Application examples:
- Built-in engines of the early motorcycle era, approx. 1910 to 1930. Many small manufacturers of bicycles expanded into the motorcycle business and built larger motorized vehicles without, however, having the design and manufacturing capabilities to develop their own engine - they bought the engines, the "built-in motors". A number of British and Swiss companies, primarily JAP and Motosacoche, were leaders in this business
- Built-in engines in automobiles (e.g. the engine of a Triumph Herald in the Berlin Amphicar 770 ). In the USA there is still an open factory outlet with mostly powerful engine variants as "crate engines" (pallet engines) aimed at private hobbyists and small series manufacturers.
- Built-in engines for aircraft (e.g. Porsche PFM 3200 ) or (ultra) light aircraft
- Motors for forest work. Today, small diesel and two-stroke engines in particular can be found as built-in engines. The companies Hatz and Lombardini may serve as examples.
- Ship engines are practically always built-in engines. Only in rare cases are shipyards also the builders of the engines. Most shipbuilding companies use built-in motors, which are used in yachts e.g. B. for the power requirement between 50 and 200 HP are often so-called "marinated" car engines or small truck engines. "Marinised" means that exhaust systems , the cooling systems and the drives ( flywheel , clutch , gearbox bell housing so rebuild), that an operation is possible on inland waterways or in the sea.
- Generator drives and motor drives as auxiliary units , e.g. B. as a precaution against power failure. In practically every hospital with an operating theater there is an emergency power unit in the basement , consisting of a truck engine and a generator and electrical control equipment. The emergency generator is started automatically in the event of a power failure in order to supply the operating theaters and other essential devices with power.
- Motors in thermal power stations (" combined heat and power ")
- Engines of diesel locomotives
- Engines of tanks
- Emergency drives in industrial plants, e.g. B. pump systems of nuclear power plants or the emergency drive of a rotary kiln to ensure that important processes continue to run and to prevent major damage in the event of a shutdown caused by a power failure.
- Emergency drives for cable cars
- Motors for remote pumping systems. Mobile pump equipment from fire brigades , e.g. B. in the past in West Germany often used a portable VW Beetle engine as the main pump drive.
For reasons of capacity and utilization, many engine manufacturers are looking for ways to open up additional markets for their products - they are also looking for sales channels for their engines as built-in engines. For this, in addition to the technical requirements in developing, manufacturing and logistics and related sales activities and a technical is documentation required - dimensional sketches , diagrams to torque curve , performance , resources - and lubricant consumption , operating and installation instructions and spare parts lists are to be compiled as to motors on the market To be able to offer built-in motors.
