Turbochargers are commonly used on truck, car, train, aircraft, and construction equipment engines. They are most often used with Otto cycle and Diesel cycle internal combustion engines. They have also been found useful in automotive fuel cells.
A repair kit or service kit is a set of items used to repair a device, commonly comprising both tools and spare parts. Many kits are designed for vehicles and may be kept with the vehicle in order to make on-the-spot repairs.
Turbochargers are commonly used in passenger cars to obtain greater power output from a given engine size. The compact nature of a turbocharger means it is often a more space-efficient solution for increasing power output than increasing engine displacement.
