reduce smoke Opel The most important news of the ways
Despite the fact that people interested in the automotive industry very keen viewing messages associated with handwritten carrying out repairs in the car or parts replacement, however, a large part of radio listeners or people viewing web pages are waiting for a completely different type of information. This is important especially when we are on the way. Well, very important are the current traffic information. More than one radio provides such information, which is certainly often awaited by drivers standing in unexpected traffic jams and so on. Thanks to that we will hear information about the accident or other traffic problems well in advance, we can even change your route so you can avoid traffic problems.
Blower scavenged

Diagram of uniflow scavenging
Using a separate blower avoids many of the shortcomings of crankcase scavenging, at the expense of increased complexity which means a higher cost and an increase in maintenance requirement. An engine of this type uses ports or valves for intake and valves for exhaust, except opposed piston engines, which may also use ports for exhaust. The blower is usually of the Roots-type but other types have been used too. This design is commonplace in CI engines, and has been occasionally used in SI engines.
CI engines that use a blower typically use uniflow scavenging. In this design the cylinder wall contains several intake ports placed uniformly spaced along the circumference just above the position that the piston crown reaches when at BDC. An exhaust valve or several like that of 4-stroke engines is used. The final part of the intake manifold is an air sleeve which feeds the intake ports. The intake ports are placed at an horizontal angle to the cylinder wall (I.e: they are in plane of the piston crown) to give a swirl to the incoming charge to improve combustion. The largest reciprocating IC are low speed CI engines of this type; they are used for marine propulsion (see marine diesel engine) or electric power generation and achieve the highest thermal efficiencies among internal combustion engines of any kind. Some Diesel-electric locomotive engines operate on the 2-stroke cycle. The most powerful of them have a brake power of around 4.5 MW or 6,000 HP. The EMD SD90MAC class of locomotives use a 2-stroke engine. The comparable class GE AC6000CW whose prime mover has almost the same brake power uses a 4-stroke engine.
An example of this type of engine is the Wärtsilä-Sulzer RTA96-C turbocharged 2-stroke Diesel, used in large container ships. It is the most efficient and powerful internal combustion engine in the world with a thermal efficiency over 50%.9101112 For comparison, the most efficient small four-stroke engines are around 43% thermally-efficient (SAE 900648);citation needed size is an advantage for efficiency due to the increase in the ratio of volume to surface area.

Automotive wins
We can easily notice that the cars or motorcycles are very often one of the main prizes in various competitions or sweepstakes. Why is it like that ? Well, these machines are often very valuable and can significantly make life easier for the winner. So valuable prize is designed to encourage more participants to take part in the common play or boot from the competition. It is a very proven grip, which for years makes competitions with prizes automotive enjoyed considerable popularity. Admittedly, win a car or a motorcycle or any other vehicle is also associated with considerable charges, which obliges us right relating to competitions; not discouraged, however, many taking part in all kinds of lotteries.
