Due to increased demand for fuel injection, high pressure fuel pump diesel is specially manufactured high-precision unit. On older models Diesel engines typically used in-line high pressure fuel pumps. Now, on most modern diesel engines are used more complex rotary pumps with a constant supply fuel, since they work better at higher engine speeds. Modern diesels use electronic control systems for dispensing fuel to achieve combustion of the process is close to ideal. Many diesel cars even equipped with converters to clean exhaust fumes. There are two types of diesel engines, and the difference between them is how they are burning. In some uses direct fuel injection.
The name itself indicates the forward direction of fuel in the combustion chamber cavity. While the injection method is very effective, the adverse parties are a lot of noise and irregularity. For this reason, direct injection diesel engines is preserved only in used by truck. However, diesel engines, improved designs of these shortcomings to a large extent eliminated, and most car manufacturers offer high-performance diesel engines with direct injection. In other diesel engines that do not use direct fuel injection, before combustion chamber creates a small additional chamber into which fuel injection occurs. Have this camera on the opposite side of the installation location and direction of the nozzle it injected fuel. This constructive approach allows to raise the engine speed, but it has to pay for some loss of power.
Yes, one of the main advantages of diesel engines – it is their efficiency. Engine volume about 1.6 liters fuel consumption on the highway about 4-4.5 L/100 km is not unusual. Without even thinking about money, it's a real pleasure, to fill the tank once and ride all the long way, not looking anxiously at the fuel gauge arrow In addition, the diesel engine – this is really such a thing, which works even when all signs should no longer work. But do not be fooled! Such a common approach, when the diesel engine, they say, can be pour anything – and diesel fuel from the tractor, and sunflower oil – very quickly lead to exactly the opposite result: the engine breaks down and will not work even after numerous attempts resurrections. Diesel engine will serve faithfully for many years only if they meet the minimum requirements for its maintenance (as well as any machine). This is a timely replacement of the right type of oil as possible – good, of separated or filtered fuel.? Timely inspection and replacement of cooling nozzles, sprayers, etc.
