Engine configuration Earlier automobile engine development produced a much larger range of engines than is in common use today.
Engines have ranged from 1- to 16-cylinder designs with corresponding differences in overall size, weight, engine displacement, and cylinder bores.Four cylinders and power ratings from 19 to 120 hp (14 to 90 kW) were followed in a majority of the models.
Several three-cylinder, two-stroke-cycle models were built while most engines had straight or in-line cylinders.
There were several V-type models and horizontally opposed two- and four-cylinder makes too.
The 1970s and 1980s saw an increased interest in improved fuel economy, which caused a return to smaller V-6 and four-cylinder layouts, with as many as five valves per cylinder to improve efficiency.The Bugatti Veyron 16.4 operates with a W16 engine, meaning that two V8 cylinder layouts are positioned next to each other to create the W shape sharing the same crankshaft. The largest internal combustion engine ever built is the Wärtsilä-Sulzer RTA96-C, a 14-cylinder, 2-stroke turbocharged diesel engine that was designed to power the Emma M?rsk, the largest container ship in the world.
This engine weighs 2,300 tons, and when running at 102 RPM produces 109,000 bhp (80,080 kW) consuming some 13.7 tons of fuel each hour.Źródło: https://en.wikipedia.org/wiki/Engine
In the event of sudden failure of the car just a phone call to a friendly mechanic to help it through the phone indicate the source of the problem and identify a solution.
Of course, the most profitable is to conduct your own garage, but working as a mechanic can also be one of the more rewarding physical activity.
For many men, it is also very enjoyable because of the interest in automobiles.
