Cylinder configuration
Common cylinder configurations include the straight or inline configuration, the more compact V configuration, and the wider but smoother flat or boxer configuration. Aircraft engines can also adopt a radial configuration, which allows more effective cooling. More unusual configurations such as the H, U, X, and W have also been used.
Multiple cylinder engines have their valve train and crankshaft configured so that pistons are at different parts of their cycle. It is desirable to have the piston's cycles uniformly spaced (this is called even firing) especially in forced induction engines; this reduces torque pulsations21 and makes inline engines with more than 3 cylinders statically balanced in its primary forces. However, some engine configurations require odd firing to achieve better balance than what is possible with even firing. For instance, a 4-stroke I2 engine has better balance when the angle between the crankpins is 180° because the pistons move in opposite directions and inertial forces partially cancel, but this gives an odd firing pattern where one cylinder fires 180° of crankshaft rotation after the other, then no cylinder fires for 540°. With an even firing pattern the pistons would move in unison and the associated forces would add.
Multiple crankshaft configurations do not necessarily need a cylinder head at all because they can instead have a piston at each end of the cylinder called an opposed piston design. Because fuel inlets and outlets are positioned at opposed ends of the cylinder, one can achieve uniflow scavenging, which, as in the four-stroke engine is efficient over a wide range of engine speeds. Thermal efficiency is improved because of a lack of cylinder heads. This design was used in the Junkers Jumo 205 diesel aircraft engine, using two crankshafts at either end of a single bank of cylinders, and most remarkably in the Napier Deltic diesel engines. These used three crankshafts to serve three banks of double-ended cylinders arranged in an equilateral triangle with the crankshafts at the corners. It was also used in single-bank locomotive engines, and is still used in marine propulsion engines and marine auxiliary generators.

Different fuels
Each fuel has its supporters and detractors. Experts automotive industry can give many reasons for allowing the selection of a suitable fuel for our car. However, not always the cheapest solution turns out to be the best for driver or car owner. For example, if you want to consider the option of supplying gas in our car, we must know that it is necessary to install proper installation. This is connected with considerable costs, but on the other hand, avoids the higher fees in the future. However, a group of drivers who decide to change their system already installed in your car, however, is quite sparse.
Choosing a used car - how to buy a really good car?
Used cars are much less expensive than acquiring your dream vehicle straight from the showroom. Not surprisingly, it is a very popular way to quickly obtain necessary sometimes the vehicle. What can you do to buy certainly a good car? Very often it is recommended to select a proposed us a car to the garage. The perfect solution would be that if we had a friendly workshop where our friend after a review by a special software this car could tell us a lot about him. Experienced car mechanics unhindered see if the car has already passed through some accident or has other hidden defects, which would like to avoid a potential car owner.
