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. Overhead camshafts were frequently employed. The smaller engines were commonly air-cooled and located at the rear of the vehicle; compression ratios were relatively low. 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.

Authorized services versus usual workshops
On the market there are very many choices when it comes to space repair our car. We decide against it at an authorized service center, which will find professionals who have a much greater knowledge about our car. This applies especially to the latest car models. There are also many possibilities to choose between the usual automotive workshops providing services such as replacement auto parts. This solution is certainly more beneficial for people who want to save money on car repair or car is already quite aged. The price difference between these two types of car repair really is often enormous.
How much is the service cars?
As you know, the price for servicing the car can sometimes be so high that a big surprise for the owner of the car. Very important is the reasonable choice of service centers, because in this area can often lead to fraud, and the potential client is not able to verify whether they were actually carried out such repairs in the car, for which he paid. The price for servicing the car depends not only on the model of the car, but also on how old our car. What's more, the price for such replacement auto parts is also dependent on the complexity of this process and on how much time the mechanic must devote to bring the car to its former glory.
