reduce smoke Mclaren high power-to-weight
Reciprocating piston engines are by far the most common power source for land and water vehicles, including automobiles, motorcycles, ships and to a lesser extent, locomotives (some are electrical but most use Diesel engines45). Rotary engines of the Wankel design are used in some automobiles, aircraft and motorcycles.
Where very high power-to-weight ratios are required, internal combustion engines appear in the form of combustion turbines or Wankel engines. Powered aircraft typically uses an ICE which may be a reciprocating engine. Airplanes can instead use jet engines and helicopters can instead employ turboshafts; both of which are types of turbines. In addition to providing propulsion, airliners may employ a separate ICE as an auxiliary power unit. Wankel engines are fitted to many unmanned aerial vehicles.
Big Diesel generator used for backup power
Combined cycle power plant
ICEs drive some of the large electric generators that power electrical grids. They are found in the form of combustion turbines in combined cycle power plants with a typical electrical output in the range of 100 MW to 1 GW. The high temperature exhaust is used to boil and superheat water to run a steam turbine. Thus, the efficiency is higher because more energy is extracted from the fuel than what could be extracted by the combustion turbine alone. In combined cycle power plants efficiencies in the range of 50% to 60% are typical. In a smaller scale Diesel generators are used for backup power and for providing electrical power to areas not connected to an electric grid.
Small engines (usually 2?stroke gasoline engines) are a common power source for lawnmowers, string trimmers, chain saws, leafblowers, pressure washers, snowmobiles, jet skis, outboard motors, mopeds, and motorcycles.

Why tuning?
Tuning cars gives them the most suitable vehicles sporty look. Many cars and motorcycles looking for faster and more efficient machine when we add a few elements. There's no denying that the tuning is often a form of gain recognition in society or gain friends, especially among younger drivers. Almost every young boy wants to have a car, but not everyone can afford it. Some elements, however, can replace their own. With the necessary financial resources should in fact invest in tuning parts, and then personally carry out improvement of our vehicle.
Cars for the rich
Luxury car brand virtually since their inception are surrounded with an aura of mystery for average earners. Although over the years the exclusive, global brand cars were beginning to reveal its secrets to the outside world and show their offer, however, to this day, some car models are intended only for the richest people in the world. Luxury cars are a sign of prestige and good luck, while allowing very stand out in the crowd. Most of them are made of special materials and to achieve a surprisingly high speed. Another advantage of these cars is equipped with many different, sometimes very expensive gadgets.
