In the early years, steam engines and electric motors were tried, but with limited success. In the 20th century, the internal combustion engine (ICE), became dominant. In 2015, the internal combustion engine remains the most widely used but a resurgence of electricity seems likely because of increasing concern about ic engine exhaust gas emissions.
The following outline is provided as an overview of and topical guide to automobiles: . Automobile (or car) – wheeled passenger vehicle that carries its own motor.Most definitions of the term specify that automobiles are designed to run primarily on roads, to have seating for one to six people, typically have four wheels, and be constructed principally for the transport of people rather than ...
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit.
The four-stroke engine is more efficient when running at full throttle, while the opposite is the case for the two-stroke engine. When a small car under heavy load runs at half speed, the engine automatically switches to the two-cycle mode, which is then more efficient. The research on this showed a 27% reduction in fuel consumption. [8] [9]

The manufacturing of powertrain components and systems is important to industry, including the automotive and other vehicle sectors. Competitiveness drives companies to engineer and produce powertrain systems that over time are more economical to manufacture, higher in product quality and reliability, higher in performance, more fuel efficient, less polluting, and longer in life expectancy.
Most car engines have four to eight cylinders, with some high-performance cars having ten, 12 — or even 16, and some very small cars and trucks having two or three. In previous years, some quite large cars such as the DKW and Saab 92, had two-cylinder or two-stroke engines.
Most engines with four or less cylinders use a straight engine layout, and most engines with eight cylinders or more use a V engine layout. However, there are various exceptions to this, such as the straight-eight engines used by various luxury cars from 1919-1954, [ 1 ] [ 2 ] [ 3 ] V4 engines used by some marine outboard motors, V-twin and ...
