Diesel oil dispensing pump

The people described frequently the engine is automobile's heart, but blows the system is diesel engine's heart. Its product quality, the assembly adjust and use the service to diesel engine's power performance, the oil consumption, the emissions and the service life decisive function. Therefore diesel engine's blow system is the modern diesel engine automobile key core system, is also in the diesel engine automobile service the specification is high and the difficulty big project. Since 1985, our country has introduced J series

Commings engine PT spray hole drop oil phenomenon analysis

In the early 80s, the Shandong bulldozer main plant the D85A-18 crawler dozer which introduced from the Japanese small pine manufacture, used the Commings engine. Commings engine PT fuel delivery system's characteristic:The fuel feed is decided in the PT pump supplies spray hole fuel pressure and opens the spray hole gauged orifice the absolute time.The PT pump is the low press pump, the discharge pressure generally in 0.8~1.2MPa, the spray hole spraying fuel oil pressure in 68~136MPa.The PT fuel system (Figure 1), fuel oil tank's position is higher than the PT pump and the PT spray hole.

Turbocharger common faults and the proper

Turbocharger is a high-temperature environment in the Super high-speed rotating machinery, speed up its work 50 000 to 240000 r / min, such high-speed rotating machinery often due to improper installation and damage caused, enabling users suffered economic losses. China currently used by the supercharger whether domestically produced or imported, are often useful life of less than the expected useful life, the reasons for more than 90 per cent is due to improper installation. Serious overloading of vehicles or users to change their own supply of life is affected supercharger the main factors. This paper presents a supercharger in the use of some common faults and the reasons for.

What is a turbo-charged technology

Diesel cars in Europe is relatively common. After years of research and applications, through the use of modern diesel engine car EFI, common-rail, turbo-charged, and other technical means, in the weight, noise, smoke, etc. has made significant achievements, reaching the level of gasoline engine. "Turbocharger" and the "new diesel engine technology", the two have already introduced the diesel engine turbocharger, EFI and common rail technology, here again on the turbo-charged diesel engine knowledge.
